+## About
+
+clownaudio is a stereo sound engine, capable of playing and mixing sounds in a
+variety of formats.
+
+Supported formats include...
+* Ogg Vorbis
+* MP3
+* Opus
+* FLAC
+* WAV
+* Various tracker formats ('.it', '.xm', '.mod', etc.)
+* PxTone Music
+* PxTone Noise
+* SNES SPC
+
+clownaudio is a 'full stack' sound engine, meaning that it handles everything
+from decoding to playback - the user merely has to provide it with sound data to
+process.
+
+That said, clownaudio's internals are modular, meaning you can easily extract
+its mixer and use it as part of your own audio system if needed.
+
+
+## Decoding backends
+
+In order to support a range of audio formats, clownaudio leverages numerous
+open-source libraries, dubbed 'decoding backends'. These libraries include...
+
+| Library     | Format     | Licence             | Included in-tree |
+|-------------|------------|---------------------|------------------|
+| libvorbis   | Ogg Vorbis | BSD                 | No               |
+| stb_vorbis  | Ogg Vorbis | Public-domain/MIT-0 | Yes              |
+| dr_mp3      | MP3        | Public-domain/MIT-0 | Yes              |
+| libopus     | Opus       | BSD                 | No               |
+| libFLAC     | FLAC       | BSD                 | No               |
+| dr_flac     | FLAC       | Public-domain/MIT-0 | Yes              |
+| dr_wav      | WAV        | Public-domain/MIT-0 | Yes              |
+| libsndfile  | Various (includes Ogg Vorbis, FLAC, WAV, AIFF, and others) | LGPL 2.1 | No |
+| libopenmpt  | Various (includes .mod, .it, .xm, .s3m, .mptm, and **many** others) | BSD | No |
+| libxmp-lite | .mod, .it, .xm, .s3m | MIT       | Yes              |
+| PxTone      | PxTone Music/PxTone Noise | Custom (appears to be permissive) | Yes |
+| snes_spc    | SNES SPC   | LGPL 2.1            | Yes              |
+
+clownaudio aims to be bloat-free and dependency-free: each decoding backend can
+be toggled at compile-time, and an effort is made to provide multiple backends
+for individual formats, to allow the user a choice between standard libraries
+(such as libvorbis), and lighter in-tree libraries (such as stb_vorbis).
+
+
+## Playback backends
+
+In addition, clownaudio utilises one of the following libraries to provide
+audio-playback:
+
+| Library   | Licence             | Included in-tree |
+|-----------|---------------------|------------------|
+| Cubeb     | ISC                 | No               |
+| miniaudio | Public-domain/MIT-0 | Yes              |
+| PortAudio | MIT                 | No               |
+| SDL1.2    | LGPL 2.1            | No               |
+| SDL2      | zlib                | No               |
+
+
+## Building
+
+clownaudio is built with CMake - both shared and static libraries can be
+produced. Built libraries can be accessed via `pkg-config` and CMake's
+`find_package`.
+
+As an alternative, CMake projects can embed clownaudio directly, using
+`add_subdirectory`.
+
+Example `Makefile` and `CMakeLists.txt` files for a demo tool are provided: the
+`Makefile` demonstrates linking clownaudio with `pkg-config`, and the
+`CMakeLists.txt` file demonstrates linking with `find_package` and embedding
+with `add_subdirectory`.
+
+`PKGBUILD` files for MSYS2 and Arch Linux are provided in the `packages`
+directory.
+
+
+## Licensing
+
+clownaudio itself is under the zlib licence.
+
+Be aware that libraries used by the various backends are subject to
+their own licences.

+

+RELEASE NOTES - v0.12.0
+=======================
+Version 0.12.0 has breaking API changes including changes to the existing API and the removal of deprecated APIs.
+
+
+Improved Client-Defined Memory Allocation
+-----------------------------------------
+The main change with this release is the addition of a more flexible way of implementing custom memory allocation routines. The
+existing system of DRFLAC_MALLOC, DRFLAC_REALLOC and DRFLAC_FREE are still in place and will be used by default when no custom
+allocation callbacks are specified.
+
+To use the new system, you pass in a pointer to a drflac_allocation_callbacks object to drflac_open() and family, like this:
+
+    void* my_malloc(size_t sz, void* pUserData)
+    {
+        return malloc(sz);
+    }
+    void* my_realloc(void* p, size_t sz, void* pUserData)
+    {
+        return realloc(p, sz);
+    }
+    void my_free(void* p, void* pUserData)
+    {
+        free(p);
+    }
+
+    ...
+
+    drflac_allocation_callbacks allocationCallbacks;
+    allocationCallbacks.pUserData = &myData;
+    allocationCallbacks.onMalloc  = my_malloc;
+    allocationCallbacks.onRealloc = my_realloc;
+    allocationCallbacks.onFree    = my_free;
+    drflac* pFlac = drflac_open_file("my_file.flac", &allocationCallbacks);
+
+The advantage of this new system is that it allows you to specify user data which will be passed in to the allocation routines.
+
+Passing in null for the allocation callbacks object will cause dr_flac to use defaults which is the same as DRFLAC_MALLOC,
+DRFLAC_REALLOC and DRFLAC_FREE and the equivalent of how it worked in previous versions.
+
+Every API that opens a drflac object now takes this extra parameter. These include the following:
+
+    drflac_open()
+    drflac_open_relaxed()
+    drflac_open_with_metadata()
+    drflac_open_with_metadata_relaxed()
+    drflac_open_file()
+    drflac_open_file_with_metadata()
+    drflac_open_memory()
+    drflac_open_memory_with_metadata()
+    drflac_open_and_read_pcm_frames_s32()
+    drflac_open_and_read_pcm_frames_s16()
+    drflac_open_and_read_pcm_frames_f32()
+    drflac_open_file_and_read_pcm_frames_s32()
+    drflac_open_file_and_read_pcm_frames_s16()
+    drflac_open_file_and_read_pcm_frames_f32()
+    drflac_open_memory_and_read_pcm_frames_s32()
+    drflac_open_memory_and_read_pcm_frames_s16()
+    drflac_open_memory_and_read_pcm_frames_f32()
+
+
+
+Optimizations
+-------------
+Seeking performance has been greatly improved. A new binary search based seeking algorithm has been introduced which significantly
+improves performance over the brute force method which was used when no seek table was present. Seek table based seeking also takes
+advantage of the new binary search seeking system to further improve performance there as well. Note that this depends on CRC which
+means it will be disabled when DR_FLAC_NO_CRC is used.
+
+The SSE4.1 pipeline has been cleaned up and optimized. You should see some improvements with decoding speed of 24-bit files in
+particular. 16-bit streams should also see some improvement.
+
+drflac_read_pcm_frames_s16() has been optimized. Previously this sat on top of drflac_read_pcm_frames_s32() and performed it's s32
+to s16 conversion in a second pass. This is now all done in a single pass. This includes SSE2 and ARM NEON optimized paths.
+
+A minor optimization has been implemented for drflac_read_pcm_frames_s32(). This will now use an SSE2 optimized pipeline for stereo
+channel reconstruction which is the last part of the decoding process.
+
+The ARM build has seen a few improvements. The CLZ (count leading zeroes) and REV (byte swap) instructions are now used when
+compiling with GCC and Clang which is achieved using inline assembly. The CLZ instruction requires ARM architecture version 5 at
+compile time and the REV instruction requires ARM architecture version 6.
+
+An ARM NEON optimized pipeline has been implemented. To enable this you'll need to add -mfpu=neon to the command line when compiling.
+
+
+Removed APIs
+------------
+The following APIs were deprecated in version 0.11.0 and have been completely removed in version 0.12.0:
+
+    drflac_read_s32()                   -> drflac_read_pcm_frames_s32()
+    drflac_read_s16()                   -> drflac_read_pcm_frames_s16()
+    drflac_read_f32()                   -> drflac_read_pcm_frames_f32()
+    drflac_seek_to_sample()             -> drflac_seek_to_pcm_frame()
+    drflac_open_and_decode_s32()        -> drflac_open_and_read_pcm_frames_s32()
+    drflac_open_and_decode_s16()        -> drflac_open_and_read_pcm_frames_s16()
+    drflac_open_and_decode_f32()        -> drflac_open_and_read_pcm_frames_f32()
+    drflac_open_and_decode_file_s32()   -> drflac_open_file_and_read_pcm_frames_s32()
+    drflac_open_and_decode_file_s16()   -> drflac_open_file_and_read_pcm_frames_s16()
+    drflac_open_and_decode_file_f32()   -> drflac_open_file_and_read_pcm_frames_f32()
+    drflac_open_and_decode_memory_s32() -> drflac_open_memory_and_read_pcm_frames_s32()
+    drflac_open_and_decode_memory_s16() -> drflac_open_memory_and_read_pcm_frames_s16()
+    drflac_open_and_decode_memory_f32() -> drflac_open_memroy_and_read_pcm_frames_f32()
+
+Prior versions of dr_flac operated on a per-sample basis whereas now it operates on PCM frames. The removed APIs all relate
+to the old per-sample APIs. You now need to use the "pcm_frame" versions.
+*/
+
+
+/*
+Introduction
+============
+dr_flac is a single file library. To use it, do something like the following in one .c file.
+
+    ```c
+    #define DR_FLAC_IMPLEMENTATION
+    #include "dr_flac.h"
+    ```
+
+You can then #include this file in other parts of the program as you would with any other header file. To decode audio data, do something like the following:
+
+    ```c
+    drflac* pFlac = drflac_open_file("MySong.flac", NULL);
+    if (pFlac == NULL) {
+        // Failed to open FLAC file
+    }
+
+    drflac_int32* pSamples = malloc(pFlac->totalPCMFrameCount * pFlac->channels * sizeof(drflac_int32));
+    drflac_uint64 numberOfInterleavedSamplesActuallyRead = drflac_read_pcm_frames_s32(pFlac, pFlac->totalPCMFrameCount, pSamples);
+    ```
+
+The drflac object represents the decoder. It is a transparent type so all the information you need, such as the number of channels and the bits per sample,
+should be directly accessible - just make sure you don't change their values. Samples are always output as interleaved signed 32-bit PCM. In the example above
+a native FLAC stream was opened, however dr_flac has seamless support for Ogg encapsulated FLAC streams as well.
+
+You do not need to decode the entire stream in one go - you just specify how many samples you'd like at any given time and the decoder will give you as many
+samples as it can, up to the amount requested. Later on when you need the next batch of samples, just call it again. Example:
+
+    ```c
+    while (drflac_read_pcm_frames_s32(pFlac, chunkSizeInPCMFrames, pChunkSamples) > 0) {
+        do_something();
+    }
+    ```
+
+You can seek to a specific PCM frame with `drflac_seek_to_pcm_frame()`.
+
+If you just want to quickly decode an entire FLAC file in one go you can do something like this:
+
+    ```c
+    unsigned int channels;
+    unsigned int sampleRate;
+    drflac_uint64 totalPCMFrameCount;
+    drflac_int32* pSampleData = drflac_open_file_and_read_pcm_frames_s32("MySong.flac", &channels, &sampleRate, &totalPCMFrameCount, NULL);
+    if (pSampleData == NULL) {
+        // Failed to open and decode FLAC file.
+    }
+
+    ...
+
+    drflac_free(pSampleData);
+    ```
+
+You can read samples as signed 16-bit integer and 32-bit floating-point PCM with the *_s16() and *_f32() family of APIs respectively, but note that these
+should be considered lossy.
+
+
+If you need access to metadata (album art, etc.), use `drflac_open_with_metadata()`, `drflac_open_file_with_metdata()` or `drflac_open_memory_with_metadata()`.
+The rationale for keeping these APIs separate is that they're slightly slower than the normal versions and also just a little bit harder to use. dr_flac
+reports metadata to the application through the use of a callback, and every metadata block is reported before `drflac_open_with_metdata()` returns.
+
+The main opening APIs (`drflac_open()`, etc.) will fail if the header is not present. The presents a problem in certain scenarios such as broadcast style
+streams or internet radio where the header may not be present because the user has started playback mid-stream. To handle this, use the relaxed APIs:
+    
+    `drflac_open_relaxed()`
+    `drflac_open_with_metadata_relaxed()`
+
+It is not recommended to use these APIs for file based streams because a missing header would usually indicate a corrupt or perverse file. In addition, these
+APIs can take a long time to initialize because they may need to spend a lot of time finding the first frame.
+
+
+
+Build Options
+=============
+#define these options before including this file.
+
+#define DR_FLAC_NO_STDIO
+  Disable `drflac_open_file()` and family.
+
+#define DR_FLAC_NO_OGG
+  Disables support for Ogg/FLAC streams.
+
+#define DR_FLAC_BUFFER_SIZE <number>
+  Defines the size of the internal buffer to store data from onRead(). This buffer is used to reduce the number of calls back to the client for more data.
+  Larger values means more memory, but better performance. My tests show diminishing returns after about 4KB (which is the default). Consider reducing this if
+  you have a very efficient implementation of onRead(), or increase it if it's very inefficient. Must be a multiple of 8.
+
+#define DR_FLAC_NO_CRC
+  Disables CRC checks. This will offer a performance boost when CRC is unnecessary. This will disable binary search seeking. When seeking, the seek table will
+  be used if available. Otherwise the seek will be performed using brute force.
+
+#define DR_FLAC_NO_SIMD
+  Disables SIMD optimizations (SSE on x86/x64 architectures, NEON on ARM architectures). Use this if you are having compatibility issues with your compiler.
+
+
+
+Notes
+=====
+- dr_flac does not support changing the sample rate nor channel count mid stream.
+- dr_flac is not thread-safe, but its APIs can be called from any thread so long as you do your own synchronization.
+- When using Ogg encapsulation, a corrupted metadata block will result in `drflac_open_with_metadata()` and `drflac_open()` returning inconsistent samples due
+  to differences in corrupted stream recorvery logic between the two APIs.

+----------

+
+pAllocationCallbacks (in, optional)
+    A pointer to application defined callbacks for managing memory allocations.
+
+
+Return Value
+------------
+Returns a pointer to an object representing the decoder.
+
+
+Remarks
+-------
+Close the decoder with `drflac_close()`.
+
+`pAllocationCallbacks` can be NULL in which case it will use `DRFLAC_MALLOC`, `DRFLAC_REALLOC` and `DRFLAC_FREE`.
+
+This function will automatically detect whether or not you are attempting to open a native or Ogg encapsulated FLAC, both of which should work seamlessly
+without any manual intervention. Ogg encapsulation also works with multiplexed streams which basically means it can play FLAC encoded audio tracks in videos.
+
+This is the lowest level function for opening a FLAC stream. You can also use `drflac_open_file()` and `drflac_open_memory()` to open the stream from a file or
+from a block of memory respectively.
+
+The STREAMINFO block must be present for this to succeed. Use `drflac_open_relaxed()` to open a FLAC stream where the header may not be present.

+as that is for internal use only.

+-------
+Close the decoder with `drflac_close()`.

+
+This is slower than `drflac_open()`, so avoid this one if you don't need metadata. Internally, this will allocate and free memory on the heap for every
+metadata block except for STREAMINFO and PADDING blocks.
+
+The caller is notified of the metadata via the `onMeta` callback. All metadata blocks will be handled before the function returns.
+
+The STREAMINFO block must be present for this to succeed. Use `drflac_open_with_metadata_relaxed()` to open a FLAC stream where the header may not be present.
+
+Note that this will behave inconsistently with `drflac_open()` if the stream is an Ogg encapsulated stream and a metadata block is corrupted. This is due to
+the way the Ogg stream recovers from corrupted pages. When `drflac_open_with_metadata()` is being used, the open routine will try to read the contents of the
+metadata block, whereas `drflac_open()` will simply seek past it (for the sake of efficiency). This inconsistency can result in different samples being
+returned depending on whether or not the stream is being opened with metadata.

+    to achieve good performance, however on GCC and Clang it's a little bit more annoying. The __builtin_clzl() and __builtin_clzll() intrinsics leave
+    it undefined as to the return value when `x` is 0. We need this to be well defined as returning 32 or 64, depending on whether or not it's a 32- or
+    64-bit build. To work around this we would need to add a conditional to check for the x = 0 case, but this creates unnecessary inefficiency. To work
+    around this problem I have written some inline assembly to emit the LZCNT (x86) or CLZ (ARM) instruction directly which removes the need to include
+    the conditional. This has worked well in the past, but for some reason Clang's MSVC compatible driver, clang-cl, does not seem to be handling this
+    in the same way as the normal Clang driver. It seems that `clang-cl` is just outputting the wrong results sometimes, maybe due to some register
+    getting clobbered?
+
+    I'm not sure if this is a bug with dr_flac's inlined assembly (most likely), a bug in `clang-cl` or just a misunderstanding on my part with inline
+    assembly rules for `clang-cl`. If somebody can identify an error in dr_flac's inlined assembly I'm happy to get that fixed.
+
+    Fortunately there is an easy workaround for this. Clang implements MSVC-specific intrinsics for compatibility. It also defines _MSC_VER for extra
+    compatibility. We can therefore just check for _MSC_VER and use the MSVC intrinsic which, fortunately for us, Clang supports. It would still be nice
+    to know how to fix the inlined assembly for correctness sake, however.

+          2) Use Ogg's framing system.
+
+        Both of these options have their own pros and cons. Using the native FLAC decoder is slower because it needs to
+        do a full decode of the frame. Using Ogg's framing system is faster, but more complicated and involves some code
+        duplication for the decoding of frame headers.
+
+        Another thing to consider is that using the Ogg framing system will perform direct seeking of the physical Ogg
+        bitstream. This is important to consider because it means we cannot read data from the drflac_bs object using the
+        standard drflac__*() APIs because that will read in extra data for its own internal caching which in turn breaks
+        the positioning of the read pointer of the physical Ogg bitstream. Therefore, anything that would normally be read
+        using the native FLAC decoding APIs, such as drflac__read_next_flac_frame_header(), need to be re-implemented so as to
+        avoid the use of the drflac_bs object.
+
+        Considering these issues, I have decided to use the slower native FLAC decoding method for the following reasons:
+          1) Seeking is already partially accelerated using Ogg's paging system in the code block above.
+          2) Seeking in an Ogg encapsulated FLAC stream is probably quite uncommon.
+          3) Simplicity.

+    - drflac_open_memory_and_read_pcm_frames_f32()
+    Set this extra parameter to NULL to use defaults which is the same as the previous behaviour. Setting this NULL will use
+    DRFLAC_MALLOC, DRFLAC_REALLOC and DRFLAC_FREE.
+  - Remove deprecated APIs:
+    - drflac_read_s32()
+    - drflac_read_s16()

+    - drflac_open_and_decode_memory_s16()
+    - drflac_open_and_decode_memory_f32()
+  - Remove drflac.totalSampleCount which is now replaced with drflac.totalPCMFrameCount. You can emulate drflac.totalSampleCount
+    by doing pFlac->totalPCMFrameCount*pFlac->channels.
+  - Rename drflac.currentFrame to drflac.currentFLACFrame to remove ambiguity with PCM frames.

+
+v0.11.0 - 2018-12-16
+  - API CHANGE: Deprecated drflac_read_s32(), drflac_read_s16() and drflac_read_f32() and replaced them with
+    drflac_read_pcm_frames_s32(), drflac_read_pcm_frames_s16() and drflac_read_pcm_frames_f32(). The new APIs take
+    and return PCM frame counts instead of sample counts. To upgrade you will need to change the input count by
+    dividing it by the channel count, and then do the same with the return value.

+  - Fix a crash when the block size of a frame is larger than the maximum block size defined by the FLAC stream.
+  - Fix a crash the the Rice partition order is invalid.
+

+  - A small optimization for the Clang build.
+
+v0.8 - 2017-08-12

+  - Bug fixes.
+
+v0.7 - 2017-07-23

+
+v0.6 - 2017-07-22
+  - Add support for recovering from invalid frames. With this change, dr_flac will simply skip over invalid frames as if they
+    never existed. Frames are checked against their sync code, the CRC-8 of the frame header and the CRC-16 of the whole frame.
+
+v0.5 - 2017-07-16
+  - Fix typos.
+  - Change drflac_bool* types to unsigned.
+  - Add CRC checking. This makes dr_flac slower, but can be disabled with #define DR_FLAC_NO_CRC.
+
+v0.4f - 2017-03-10
+  - Fix a couple of bugs with the bitstreaming code.
+

+  - API/ABI CHANGE: Use fixed size 32-bit booleans instead of the built-in bool type.
+  - API CHANGE: Rename drflac_open_and_decode*() to drflac_open_and_decode*_s32().
+  - API CHANGE: Swap the order of "channels" and "sampleRate" parameters in drflac_open_and_decode*(). Rationale for this is to
+    keep it consistent with drflac_audio.
+
+v0.3f - 2016-09-21
+  - Fix a warning with GCC.
+
+v0.3e - 2016-09-18

+  - Removed an unused debugging variable
+
+v0.2 - 2016-05-09
+  - Added support for Ogg encapsulation.
+  - API CHANGE. Have the onSeek callback take a third argument which specifies whether or not the seek
+    should be relative to the start or the current position. Also changes the seeking rules such that
+    seeking offsets will never be negative.
+  - Have drflac_open_and_decode() fail gracefully if the stream has an unknown total sample count.
+
+v0.1b - 2016-05-07

+
+/*
+RELEASE NOTES - VERSION 0.6
+===========================
+Version 0.6 includes breaking changes with the configuration of decoders. The ability to customize the number of output channels and the sample rate has been
+removed. You must now use the channel count and sample rate reported by the MP3 stream itself, and all channel and sample rate conversion must be done
+yourself.
+
+
+Changes to Initialization
+-------------------------
+Previously, `drmp3_init()`, etc. took a pointer to a `drmp3_config` object that allowed you to customize the output channels and sample rate. This has been
+removed. If you need the old behaviour you will need to convert the data yourself or just not upgrade. The following APIs have changed.
+
+    `drmp3_init()`
+    `drmp3_init_memory()`
+    `drmp3_init_file()`
+
+
+Miscellaneous Changes
+---------------------
+Support for loading a file from a `wchar_t` string has been added via the `drmp3_init_file_w()` API.
+*/
+
+/*
+Introducation
+=============
+dr_mp3 is a single file library. To use it, do something like the following in one .c file.
+
+    ```c
+    #define DR_MP3_IMPLEMENTATION
+    #include "dr_mp3.h"
+    ```
+
+You can then #include this file in other parts of the program as you would with any other header file. To decode audio data, do something like the following:
+
+    ```c
+    drmp3 mp3;
+    if (!drmp3_init_file(&mp3, "MySong.mp3", NULL)) {
+        // Failed to open file
+    }
+
+    ...
+
+    drmp3_uint64 framesRead = drmp3_read_pcm_frames_f32(pMP3, framesToRead, pFrames);
+    ```
+
+The drmp3 object is transparent so you can get access to the channel count and sample rate like so:
+
+    ```
+    drmp3_uint32 channels = mp3.channels;
+    drmp3_uint32 sampleRate = mp3.sampleRate;
+    ```
+
+The example above initializes a decoder from a file, but you can also initialize it from a block of memory and read and seek callbacks with
+`drmp3_init_memory()` and `drmp3_init()` respectively.
+
+You do not need to do any annoying memory management when reading PCM frames - this is all managed internally. You can request any number of PCM frames in each
+call to `drmp3_read_pcm_frames_f32()` and it will return as many PCM frames as it can, up to the requested amount.
+
+You can also decode an entire file in one go with `drmp3_open_and_read_pcm_frames_f32()`, `drmp3_open_memory_and_read_pcm_frames_f32()` and
+`drmp3_open_file_and_read_pcm_frames_f32()`.
+
+
+Build Options
+=============
+#define these options before including this file.
+
+#define DR_MP3_NO_STDIO
+  Disable drmp3_init_file(), etc.
+
+#define DR_MP3_NO_SIMD
+  Disable SIMD optimizations.

+DIFFERENCES BETWEEN minimp3 AND dr_mp3
+======================================
+- First, keep in mind that minimp3 (https://github.com/lieff/minimp3) is where all the real work was done. All of the
+  code relating to the actual decoding remains mostly unmodified, apart from some namespacing changes.
+- dr_mp3 adds a pulling style API which allows you to deliver raw data via callbacks. So, rather than pushing data
+  to the decoder, the decoder _pulls_ data from your callbacks.
+- In addition to callbacks, a decoder can be initialized from a block of memory and a file.
+- The dr_mp3 pull API reads PCM frames rather than whole MP3 frames.
+- dr_mp3 adds convenience APIs for opening and decoding entire files in one go.
+- dr_mp3 is fully namespaced, including the implementation section, which is more suitable when compiling projects
+  as a single translation unit (aka unity builds). At the time of writing this, a unity build is not possible when
+  using minimp3 in conjunction with stb_vorbis. dr_mp3 addresses this.
+*/
+
+/*
+RELEASE NOTES - v0.5.0
+=======================
+Version 0.5.0 has breaking API changes.
+
+Improved Client-Defined Memory Allocation
+-----------------------------------------
+The main change with this release is the addition of a more flexible way of implementing custom memory allocation routines. The
+existing system of DRMP3_MALLOC, DRMP3_REALLOC and DRMP3_FREE are still in place and will be used by default when no custom
+allocation callbacks are specified.
+
+To use the new system, you pass in a pointer to a drmp3_allocation_callbacks object to drmp3_init() and family, like this:
+
+    void* my_malloc(size_t sz, void* pUserData)
+    {
+        return malloc(sz);
+    }
+    void* my_realloc(void* p, size_t sz, void* pUserData)
+    {
+        return realloc(p, sz);
+    }
+    void my_free(void* p, void* pUserData)
+    {
+        free(p);
+    }
+
+    ...
+
+    drmp3_allocation_callbacks allocationCallbacks;
+    allocationCallbacks.pUserData = &myData;
+    allocationCallbacks.onMalloc  = my_malloc;
+    allocationCallbacks.onRealloc = my_realloc;
+    allocationCallbacks.onFree    = my_free;
+    drmp3_init_file(&mp3, "my_file.mp3", NULL, &allocationCallbacks);
+
+The advantage of this new system is that it allows you to specify user data which will be passed in to the allocation routines.
+
+Passing in null for the allocation callbacks object will cause dr_mp3 to use defaults which is the same as DRMP3_MALLOC,
+DRMP3_REALLOC and DRMP3_FREE and the equivalent of how it worked in previous versions.
+
+Every API that opens a drmp3 object now takes this extra parameter. These include the following:
+
+    drmp3_init()
+    drmp3_init_file()
+    drmp3_init_memory()
+    drmp3_open_and_read_pcm_frames_f32()
+    drmp3_open_and_read_pcm_frames_s16()
+    drmp3_open_memory_and_read_pcm_frames_f32()
+    drmp3_open_memory_and_read_pcm_frames_s16()
+    drmp3_open_file_and_read_pcm_frames_f32()
+    drmp3_open_file_and_read_pcm_frames_s16()
+
+Renamed APIs
+------------
+The following APIs have been renamed for consistency with other dr_* libraries and to make it clear that they return PCM frame
+counts rather than sample counts.
+
+    drmp3_open_and_read_f32()        -> drmp3_open_and_read_pcm_frames_f32()
+    drmp3_open_and_read_s16()        -> drmp3_open_and_read_pcm_frames_s16()
+    drmp3_open_memory_and_read_f32() -> drmp3_open_memory_and_read_pcm_frames_f32()
+    drmp3_open_memory_and_read_s16() -> drmp3_open_memory_and_read_pcm_frames_s16()
+    drmp3_open_file_and_read_f32()   -> drmp3_open_file_and_read_pcm_frames_f32()
+    drmp3_open_file_and_read_s16()   -> drmp3_open_file_and_read_pcm_frames_s16()

+  - Add support for C89.
+  - Change license to choice of public domain or MIT-0.
+
+v0.4.2 - 2019-02-21

+  - Bring up to date with minimp3. This has a minor API change: the "pcm" parameter of drmp3dec_decode_frame() has
+    been changed from short* to void* because it can now output both s16 and f32 samples, depending on whether or
+    not the DR_MP3_FLOAT_OUTPUT option is set.
+

+RELEASE NOTES - VERSION 0.12
+============================
+Version 0.12 includes breaking changes to custom chunk handling.
+
+
+Changes to Chunk Callback
+-------------------------
+dr_wav supports the ability to fire a callback when a chunk is encounted (except for WAVE and FMT chunks). The callback has been updated to include both the
+container (RIFF or Wave64) and the FMT chunk which contains information about the format of the data in the wave file.
+
+Previously, there was no direct way to determine the container, and therefore no way to discriminate against the different IDs in the chunk header (RIFF and
+Wave64 containers encode chunk ID's differently). The `container` parameter can be used to know which ID to use.
+
+Sometimes it can be useful to know the data format at the time the chunk callback is fired. A pointer to a `drwav_fmt` object is now passed into the chunk
+callback which will give you information about the data format. To determine the sample format, use `drwav_fmt_get_format()`. This will return one of the
+`DR_WAVE_FORMAT_*` tokens.
+*/
+
+/*
+Introduction
+============
+This is a single file library. To use it, do something like the following in one .c file.
+    
+    ```c
+    #define DR_WAV_IMPLEMENTATION
+    #include "dr_wav.h"
+    ```
+
+You can then #include this file in other parts of the program as you would with any other header file. Do something like the following to read audio data:
+
+    ```c
+    drwav wav;
+    if (!drwav_init_file(&wav, "my_song.wav", NULL)) {
+        // Error opening WAV file.
+    }
+
+    drwav_int32* pDecodedInterleavedPCMFrames = malloc(wav.totalPCMFrameCount * wav.channels * sizeof(drwav_int32));
+    size_t numberOfSamplesActuallyDecoded = drwav_read_pcm_frames_s32(&wav, wav.totalPCMFrameCount, pDecodedInterleavedPCMFrames);
+
+    ...
+
+    drwav_uninit(&wav);
+    ```
+
+If you just want to quickly open and read the audio data in a single operation you can do something like this:
+
+    ```c
+    unsigned int channels;
+    unsigned int sampleRate;
+    drwav_uint64 totalPCMFrameCount;
+    float* pSampleData = drwav_open_file_and_read_pcm_frames_f32("my_song.wav", &channels, &sampleRate, &totalPCMFrameCount, NULL);
+    if (pSampleData == NULL) {
+        // Error opening and reading WAV file.
+    }
+
+    ...
+
+    drwav_free(pSampleData);
+    ```
+
+The examples above use versions of the API that convert the audio data to a consistent format (32-bit signed PCM, in this case), but you can still output the
+audio data in its internal format (see notes below for supported formats):
+
+    ```c
+    size_t framesRead = drwav_read_pcm_frames(&wav, wav.totalPCMFrameCount, pDecodedInterleavedPCMFrames);
+    ```
+
+You can also read the raw bytes of audio data, which could be useful if dr_wav does not have native support for a particular data format:
+
+    ```c
+    size_t bytesRead = drwav_read_raw(&wav, bytesToRead, pRawDataBuffer);
+    ```
+
+dr_wav can also be used to output WAV files. This does not currently support compressed formats. To use this, look at `drwav_init_write()`,
+`drwav_init_file_write()`, etc. Use `drwav_write_pcm_frames()` to write samples, or `drwav_write_raw()` to write raw data in the "data" chunk.
+
+    ```c
+    drwav_data_format format;
+    format.container = drwav_container_riff;     // <-- drwav_container_riff = normal WAV files, drwav_container_w64 = Sony Wave64.
+    format.format = DR_WAVE_FORMAT_PCM;          // <-- Any of the DR_WAVE_FORMAT_* codes.
+    format.channels = 2;
+    format.sampleRate = 44100;
+    format.bitsPerSample = 16;
+    drwav_init_file_write(&wav, "data/recording.wav", &format, NULL);
+
+    ...
+
+    drwav_uint64 framesWritten = drwav_write_pcm_frames(pWav, frameCount, pSamples);
+    ```
+
+dr_wav has seamless support the Sony Wave64 format. The decoder will automatically detect it and it should Just Work without any manual intervention.
+
+
+Build Options
+=============
+#define these options before including this file.
+
+#define DR_WAV_NO_CONVERSION_API
+  Disables conversion APIs such as `drwav_read_pcm_frames_f32()` and `drwav_s16_to_f32()`.
+
+#define DR_WAV_NO_STDIO
+  Disables APIs that initialize a decoder from a file such as `drwav_init_file()`, `drwav_init_file_write()`, etc.
+
+
+
+Notes
+=====
+- Samples are always interleaved.
+- The default read function does not do any data conversion. Use `drwav_read_pcm_frames_f32()`, `drwav_read_pcm_frames_s32()` and `drwav_read_pcm_frames_s16()`
+  to read and convert audio data to 32-bit floating point, signed 32-bit integer and signed 16-bit integer samples respectively. Tested and supported internal
+  formats include the following:
+  - Unsigned 8-bit PCM
+  - Signed 12-bit PCM
+  - Signed 16-bit PCM
+  - Signed 24-bit PCM
+  - Signed 32-bit PCM
+  - IEEE 32-bit floating point
+  - IEEE 64-bit floating point
+  - A-law and u-law
+  - Microsoft ADPCM
+  - IMA ADPCM (DVI, format code 0x11)
+- dr_wav will try to read the WAV file as best it can, even if it's not strictly conformant to the WAV format.

+RELEASE NOTES - v0.11.0
+=======================
+Version 0.11.0 has breaking API changes.
+
+Improved Client-Defined Memory Allocation
+-----------------------------------------
+The main change with this release is the addition of a more flexible way of implementing custom memory allocation routines. The
+existing system of DRWAV_MALLOC, DRWAV_REALLOC and DRWAV_FREE are still in place and will be used by default when no custom
+allocation callbacks are specified.
+
+To use the new system, you pass in a pointer to a drwav_allocation_callbacks object to drwav_init() and family, like this:
+
+    void* my_malloc(size_t sz, void* pUserData)
+    {
+        return malloc(sz);
+    }
+    void* my_realloc(void* p, size_t sz, void* pUserData)
+    {
+        return realloc(p, sz);
+    }
+    void my_free(void* p, void* pUserData)
+    {
+        free(p);
+    }
+
+    ...
+
+    drwav_allocation_callbacks allocationCallbacks;
+    allocationCallbacks.pUserData = &myData;
+    allocationCallbacks.onMalloc  = my_malloc;
+    allocationCallbacks.onRealloc = my_realloc;
+    allocationCallbacks.onFree    = my_free;
+    drwav_init_file(&wav, "my_file.wav", &allocationCallbacks);
+
+The advantage of this new system is that it allows you to specify user data which will be passed in to the allocation routines.
+
+Passing in null for the allocation callbacks object will cause dr_wav to use defaults which is the same as DRWAV_MALLOC,
+DRWAV_REALLOC and DRWAV_FREE and the equivalent of how it worked in previous versions.
+
+Every API that opens a drwav object now takes this extra parameter. These include the following:
+
+    drwav_init()
+    drwav_init_ex()
+    drwav_init_file()
+    drwav_init_file_ex()
+    drwav_init_file_w()
+    drwav_init_file_w_ex()
+    drwav_init_memory()
+    drwav_init_memory_ex()
+    drwav_init_write()
+    drwav_init_write_sequential()
+    drwav_init_write_sequential_pcm_frames()
+    drwav_init_file_write()
+    drwav_init_file_write_sequential()
+    drwav_init_file_write_sequential_pcm_frames()
+    drwav_init_file_write_w()
+    drwav_init_file_write_sequential_w()
+    drwav_init_file_write_sequential_pcm_frames_w()
+    drwav_init_memory_write()
+    drwav_init_memory_write_sequential()
+    drwav_init_memory_write_sequential_pcm_frames()
+    drwav_open_and_read_pcm_frames_s16()
+    drwav_open_and_read_pcm_frames_f32()
+    drwav_open_and_read_pcm_frames_s32()
+    drwav_open_file_and_read_pcm_frames_s16()
+    drwav_open_file_and_read_pcm_frames_f32()
+    drwav_open_file_and_read_pcm_frames_s32()
+    drwav_open_file_and_read_pcm_frames_s16_w()
+    drwav_open_file_and_read_pcm_frames_f32_w()
+    drwav_open_file_and_read_pcm_frames_s32_w()
+    drwav_open_memory_and_read_pcm_frames_s16()
+    drwav_open_memory_and_read_pcm_frames_f32()
+    drwav_open_memory_and_read_pcm_frames_s32()
+
+Endian Improvements
+-------------------
+Previously, the following APIs returned little-endian audio data. These now return native-endian data. This improves compatibility
+on big-endian architectures.
+
+    drwav_read_pcm_frames()
+    drwav_read_pcm_frames_s16()
+    drwav_read_pcm_frames_s32()
+    drwav_read_pcm_frames_f32()
+    drwav_open_and_read_pcm_frames_s16()
+    drwav_open_and_read_pcm_frames_s32()
+    drwav_open_and_read_pcm_frames_f32()
+    drwav_open_file_and_read_pcm_frames_s16()
+    drwav_open_file_and_read_pcm_frames_s32()
+    drwav_open_file_and_read_pcm_frames_f32()
+    drwav_open_file_and_read_pcm_frames_s16_w()
+    drwav_open_file_and_read_pcm_frames_s32_w()
+    drwav_open_file_and_read_pcm_frames_f32_w()
+    drwav_open_memory_and_read_pcm_frames_s16()
+    drwav_open_memory_and_read_pcm_frames_s32()
+    drwav_open_memory_and_read_pcm_frames_f32()
+
+APIs have been added to give you explicit control over whether or not audio data is read or written in big- or little-endian byte
+order:
+
+    drwav_read_pcm_frames_le()
+    drwav_read_pcm_frames_be()
+    drwav_read_pcm_frames_s16le()
+    drwav_read_pcm_frames_s16be()
+    drwav_read_pcm_frames_f32le()
+    drwav_read_pcm_frames_f32be()
+    drwav_read_pcm_frames_s32le()
+    drwav_read_pcm_frames_s32be()
+    drwav_write_pcm_frames_le()
+    drwav_write_pcm_frames_be()
+
+Removed APIs
+------------
+The following APIs were deprecated in version 0.10.0 and have now been removed:
+
+    drwav_open()
+    drwav_open_ex()
+    drwav_open_write()
+    drwav_open_write_sequential()
+    drwav_open_file()
+    drwav_open_file_ex()
+    drwav_open_file_write()
+    drwav_open_file_write_sequential()
+    drwav_open_memory()
+    drwav_open_memory_ex()
+    drwav_open_memory_write()
+    drwav_open_memory_write_sequential()
+    drwav_close()
+
+

+
+See release notes for version 0.9.0 at the bottom of this file for replacement APIs.
+
+Deprecated APIs
+---------------
+The following APIs have been deprecated. There is a confusing and completely arbitrary difference between drwav_init*() and
+drwav_open*(), where drwav_init*() initializes a pre-allocated drwav object, whereas drwav_open*() will first allocated a
+drwav object on the heap and then initialize it. drwav_open*() has been deprecated which means you must now use a pre-
+allocated drwav object with drwav_init*(). If you need the previous functionality, you can just do a malloc() followed by
+a called to one of the drwav_init*() APIs.
+
+    drwav_open()
+    drwav_open_ex()
+    drwav_open_write()
+    drwav_open_write_sequential()
+    drwav_open_file()
+    drwav_open_file_ex()
+    drwav_open_file_write()
+    drwav_open_file_write_sequential()
+    drwav_open_memory()
+    drwav_open_memory_ex()
+    drwav_open_memory_write()
+    drwav_open_memory_write_sequential()
+    drwav_close()
+
+These APIs will be removed completely in a future version. The rationale for this change is to remove confusion between the
+two different ways to initialize a drwav object.

+Requirements
+------------
+
+- This package needs to be built using GNU make
+  (https://www.gnu.org/software/make/). On BSD or SysV systems, you may
+  need to use "gmake" instead of "make".
+
+
+Building the library
+--------------------
+
+In most systems just execute:
+
+  $ ./configure
+  $ make
+
+We'll build the shared library by default. Use ./configure --enable-static
+to build the static library. To check if the library was correctly built,
+run:
+
+  $ make check
+
+Use ./configure --help to see more options.
+
+
+Installation
+------------
+
+To install the library and development components, just run:
+
+# make install
+
+as the superuser. This will install the shared and static libraries,
+header file and pkg-config file into directories under /usr/local or a
+different location selected with the --prefix option in configure.
+

+Libxmp-lite is a lean and lightweight subset of Libxmp that plays MOD, S3M,
+XM, and IT modules and retains full compatibility with the original API.
+It's intended for games and small or embedded applications where module
+format diversity and file depacking are not required.
+
+Library size can be further reduced by disabling Impulse Tracker format
+support (configure with --disable-it). This option will also disable IT
+effects and lowpass filtering.
+
+Please refer to http://xmp.sf.net/libxmp.html for details on the current
+Libxmp API.

+\`configure' configures this package to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:

+
+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+ *  note (instead of doing something like tick%3 or similar). The LUT only has
+ *  16 entries, so when there are more than 16 ticks, it reads beyond array
+ *  boundaries. The vibrato table happens to be stored right after arpeggio
+ *  table. The tables look like this in memory:
+ *
+ *    ArpTab: 0,1,2,0,1,2,0,1,2,0,1,2,0,1,2,0
+ *    VibTab: 0,24,49,74,97,120,141,161,180,197,...
+ *
+ *  All values except for the first in the vibrato table are greater than 1, so
+ *  they trigger the third arpeggio note. Keep in mind that Fasttracker 2 counts
+ *  downwards, so the table has to be read from back to front, i.e. at 16 ticks
+ *  per row, the 16th entry in the LUT is the first to be read. This is also the
+ *  reason why Arpeggio is played 'backwards' in Fasttracker 2."

+snes_spc Change Log
+-------------------
+
+snes_spc 0.9.0
+--------------
+- Improved documentation
+
+- SPC: Added spc_skip() function for quickly seeking in an SPC music
+file. Runs 3-4x faster than normal playback using the fast DSP (or about
+43-60X real-time on my 400 MHz Mac).
+
+- SPC: Added spc_set_tempo() to change tempo of SPC music playback.
+
+- SPC: Sample generation is now corrected to generate exactly one pair
+of samples every 32 clocks without exception. Before it could generate a
+few samples more or less depending on how far ahead or behind DSP was at
+the moment.
+
+- SPC: Changed spc_reset() and spc_soft_reset() to also reset output
+buffer (see spc.h).
+
+- SPC: Fixed minor timer counting bug.
+
+- SPC: Stack pointer wrap-around is now emulated (and without any
+noticeable performance hit).
+
+- SPC: Runs about 5% faster due to various optimizations.
+
+- SPC: Found way to make fast DSP register accesses cycle-accurate in
+most cases, without reducing performance. Allows fast DSP to pass most
+of my validation tests.
+
+- DSP: Added surround disable support to fast DSP again.
+
+- DSP: Improved voice un-muting to take effect immediately on fast DSP.
+
+- DSP: Noise shift register now starts at 0x4000 instead of 0x4001 as it
+incorrectly did before.
+
+- Converted library to C++ code internally. A C interface is still
+included in spc.h and dsp.h. Note that these are different than the
+previous interface, so your code will require minor changes:
+

+	spc = malloc( sizeof (snes_spc_t) );    spc = spc_new();
+	spc_init( spc );
+	
+	spc_end_frame( time );                  spc_end_frame( spc, time );
+	/* etc. */
+	
+	/* done using SPC */                    spc_delete( spc );

+											dsp = spc_dsp_new();
+											spc_dsp_init( dsp, ram );
+	
+	spc_dsp_run( count );                   spc_dsp_run( dsp, count );
+	/* etc. */
+	
+	/* done using DSP */                    spc_dsp_delete( dsp );
+	
+
+snes_spc 0.8.0
+--------------
+- Added several demos
+
+- Added high-pass/low-pass filter to better match SNES sound
+
+- Added save state functionality for SPC and accurate DSP (but not fast
+DSP)
+
+- Added emulation of reset switch on NES (soft reset)
+
+- Made source more compatible with pre-C99 compilers by eliminating
+mid-block declarations
+
+- SPC: Many S-SMP accuracy improvements, mostly in memory access times
+
+- SPC: S-SMP speed improvements
+
+- SPC: Added SPC load/save functions and KON checking to help trim
+silence from beginning
+
+- SPC: Changed spc_init() to have you allocate most of the memory used
+by the library so you have more control over it
+
+- DSP: New highly accurate DSP and faster version derived from same code
+
+- DSP: Changed prefix from dsp_ to spc_dsp_. Your DSP code will require
+changes.
+
+- DSP: Removed surround disable and gain. Gain can now be done with the
+dsp_filter module, and surround disable will probably only be
+implemented in the fast DSP at some point.
+
+- DSP: Changed interface to work in clocks rather than samples,
+necessary for the new accurate DSP. Sample output is now done with
+separate functions. Your DSP code will require changes.

+		  GNU LESSER GENERAL PUBLIC LICENSE
+		       Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+		  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+  
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+			    NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Lesser General Public
+    License as published by the Free Software Foundation; either
+    version 2.1 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Lesser General Public License for more details.
+
+    You should have received a copy of the GNU Lesser General Public
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James Random Hacker.

+snes_spc 0.9.0: SNES SPC-700 APU Emulator
+-----------------------------------------
+This library includes a full SPC emulator and an S-DSP emulator that can
+be used on its own. Two S-DSP emulators are available: a highly accurate
+one for use in a SNES emulator, and a 3x faster one for use in an SPC
+music player or a resource-limited SNES emulator.
+
+* Can be used from C and C++ code
+* Full SPC-700 APU emulator with cycle accuracy in most cases
+* Loads, plays, and saves SPC music files
+* Can save and load exact full emulator state
+* DSP voice muting, surround sound disable, and song tempo adjustment
+* Uses 7% CPU average on 400 MHz Mac to play an SPC using fast DSP
+
+The accurate DSP emulator is based on past research by others and
+hundreds of hours of recent research by me. It passes over a hundred
+strenuous timing and behavior validation tests that were also run on the
+SNES. As far as I know, it's the first DSP emulator with cycle accuracy,
+properly emulating every DSP register and memory access at the exact SPC
+cycle it occurs at, whereas previous DSP emulators emulated these only
+to the nearest sample (which occurs every 32 clocks).

+Getting Started
+---------------
+Build a program consisting of demo/play_spc.c, demo/demo_util.c,
+demo/wave_writer.c, and all source files in snes_spc/. Put an SPC music
+file in the same directory and name it "test.spc". Running the program
+should generate the recording "out.wav".
+
+Read snes_spc.txt for more information. Post to the discussion forum for

+C and C++ Interfaces
+--------------------
+The library includes a C interface in spc.h and dsp.h, which can be used
+from C and C++. This C interface is referred to in the following
+documentation. If you're building this as a shared library (rather than
+linking statically), you should use the C interface since it will change
+less in future versions.
+
+The native C++ interface is in the header files SNES_SPC.h, SPC_DSP.h,
+and SPC_Filter.h, and the two interfaces can be freely mixed in C++
+code. Conversion between the two interfaces generally follows a pattern:
+
+	C interface                     C++ interface
+	- - - - - - - - - - - - - - - - - - - - - - - - - - - - -
+	SNES_SPC* spc;                  SNES_SPC* spc;
+	
+	spc = spc_new();                spc = new SNES_SPC;
+	
+	spc_play( spc, count, buf );    spc->play( count, buf );
+	
+	spc_sample_rate                 SNES_SPC::sample_rate
+	
+	spc_delete( spc );              delete spc;
+
+
+Overview
+--------
+There are three main roles for this library:
+* Full SPC emulation in a SNES emulator
+* DSP emulation in a SNES emulator (where you emulate the SMP CPU)
+* SPC playback in an SPC music file player
+
+Each of these uses are described separately below.
+
+
+Full SPC Emulation
+------------------
+See spc.h for full function reference (SNES_SPC.h if using C++).
+
+* Create SPC emulator with spc_new() and check for NULL.
+
+* Call spc_init_rom() with a pointer to the 64-byte IPL ROM dump (not
+included with library).
+
+* When your emulated SNES is powered on, call spc_reset(). When the
+reset switch is pressed, call spc_soft_reset().
+
+* Call spc_set_output() with your output buffer, then do emulation.
+
+* When the SNES CPU accesses APU ports, call spc_read_port() and
+spc_write_port().
+
+* When your emulator's timebase is going back to 0, call
+spc_end_frame(), usually at the end of a video frame or scanline.
+
+* Periodically play samples from your buffer. Use spc_sample_count() to
+find out how many samples have been written, then spc_set_output() after
+you've made more space in your buffer.
+
+* Save/load full emulator state with spc_copy_state().
+
+* You can save as an SPC music file with spc_save_spc().
+
+* When done, use spc_delete() to free memory.
+
+
+DSP Emulation
+-------------
+See dsp.h for full function reference (SPC_DSP.h if using C++).
+
+* Create DSP emulator with spc_dsp_new() and check for NULL.
+
+* Let the DSP know where your 64K RAM is with spc_dsp_init().
+
+* When your emulated SNES is powered on, call spc_dsp_reset(). When the
+reset switch is pressed, call spc_dsp_soft_reset().
+
+* Call spc_dsp_set_output() with your output buffer, then do emulation.
+
+* Use spc_dsp_run() to run DSP for specified number of clocks (1024000
+per second). Every 32 clocks a pair of samples is added to your output
+buffer.
+
+* Use spc_dsp_read() and spc_dsp_write() to handle DSP reads/writes from
+the S-SMP. Before calling these always catch the DSP up to present time
+with spc_dsp_run().
+
+* Periodically play samples from your buffer. Use spc_dsp_sample_count()
+to find out how many samples have been written, then
+spc_dsp_set_output() after you've made more space in your buffer.
+
+* Use spc_dsp_copy_state() to save/load full DSP state.
+
+* When done, use spc_delete() to free memory.
+
+
+SPC Music Playback
+------------------
+See spc.h for full function reference (SNES_SPC.h if using C++).
+
+* Create SPC emulator with spc_new() and check for NULL.
+
+* Load SPC with spc_load_spc() and check for error.
+
+* Optionally cear echo buffer with spc_clear_echo(). Many SPCs have
+garbage in echo buffer, which causes noise at the beginning.
+
+* Generate samples as needed with spc_play().
+
+* When done, use spc_delete() to free memory.
+
+* For a more complete game music playback library, use Game_Music_Emu
+
+
+State Copying
+-------------
+The SPC and DSP modules include state save/load functions. They take a
+pointer to a pointer to a buffer to store state, and a copy function.
+This copy function can either copy data to the buffer or from it,
+allowing state save and restore with the same library function. The
+internal save state format allows for future expansion without making
+previous save states unusable.
+
+The SPC save state format puts the most important parts first to make it
+easier to manually examine. It's organized as follows:
+
+Offset  Size    Data
+- - - - - - - - - - - - - - - - - -
+     0 $10000   SPC RAM
+$10000    $10   SMP $F0-$FF registers
+$10010      4   SMP $F4-$F8 output registers
+$10014      2   PC
+$10016      1   A
+$10017      1   X
+$10018      1   Y
+$10019      1   PSW
+$1001A      1   SP
+$1001B      5   internal
+$10020    $80   DSP registers
+$100A0    ...   internal
+
+
+Library Compilation
+-------------------
+While this library is in C++, it has been written to easily link in a C
+program *without* needing the standard C++ library. It doesn't use
+exception handling or run-time type information (RTTI), so you can
+disable these in your C++ compiler to increase efficiency.
+
+If you're building a shared library (DLL), I recommend only exporting
+the C interfaces in spc.h and dsp.h, as the C++ interfaces expose
+implementation details that will break link compatibility across
+versions.
+
+If you're using C and compiling with GCC, I recommend the following
+command-line options when compiling the library source, otherwise GCC
+will insert calls to the standard C++ library and require that it be
+linked in:
+
+	-fno-rtti -fno-exceptions
+
+For maximum optimization, see the NDEBUG and BLARGG_NONPORTABLE options
+in blargg_config. If using GCC, you can enable these by adding the
+following command-line options when you invoke gcc. If you encounter
+problems, try without -DBLARGG_NONPORTABLE; if that works, contact me so
+I can figure out why BLARGG_NONPORTABLE was causing it to fail.
+
+	-O3 -DNDEBUG -DBLARGG_NONPORTABLE -fno-rtti -fno-exceptions
+
+
+
+Error handling
+--------------
+Functions which can fail have a return type of spc_err_t (blargg_err_t
+in the C++ interfaces), which is a pointer to an error string (const
+char*). If a function is successful it returns NULL. Errors that you can
+easily avoid are checked with debug assertions; spc_err_t return values
+are only used for genuine run-time errors that can't be easily predicted
+in advance (out of memory, I/O errors, incompatible file data). Your
+code should check all error values.
+
+To improve usability for C programmers, C++ programmers unfamiliar with
+exceptions, and compatibility with older C++ compilers, the library does
+*not* throw any C++ exceptions and uses malloc() instead of the standard
+operator new. This means that you *must* check for NULL when creating a
+library object with the new operator.
+
+
+Solving Problems
+----------------
+If you're having problems, try the following:
+
+* If you're getting garbled sound, try this simple siren generator in
+place of your call to play(). This will quickly tell whether the problem
+is in the library or in your code.
+
+	static void play_siren( long count, short* out )
+	{
+		static double a, a2;
+		while ( count-- )
+			*out++ = 0x2000 * sin( a += .1 + .05*sin( a2+=.00005 ) );
+	}
+
+* Enable debugging support in your environment. This enables assertions
+and other run-time checks.
+
+* Turn the compiler's optimizer is off. Sometimes an optimizer generates
+bad code.
+
+* If multiple threads are being used, ensure that only one at a time is
+accessing a given set of objects from the library. This library is not
+in general thread-safe, though independent objects can be used in
+separate threads.
+
+* If all else fails, see if the demos work.
+
+
+Accurate S-DSP Limitations
+--------------------------
+* Power-up and soft reset behavior might have slight inaccuracies.
+
+* Muting (FLG bit 6) behavior when toggling bit very rapidly is not
+emulated properly.
+
+* No other known inaccuracies. Has passed 100+ strenuous tests.
+
+
+Fast S-DSP Limitations
+----------------------
+* Uses faster sample calculations except in cases where exact value is
+actually important (BRR decoding, and gaussian interpolation combined
+with pitch modulation).
+
+* Stops decoding BRR data when a voice's envelope has released to
+silence.
+
+* Emulates 32 clocks at a time, so DSP register and memory accesses are
+all done in a bunch rather than spread out. Even though, some clever
+code makes register accesses separated by 40 or so clocks occur with
+cycle-accurate timing.
+
+
+S-SMP Limitations
+-----------------
+* Opcode fetches and indirect pointers are always read directly from
+memory, even for the $F0-$FF region, and the DSP is not caught up for
+these fetches.
+
+* Attempts to perversely execute data in registers or an area being
+modified by echo will not be emulated properly.
+
+* Has not been thoroughly tested.
+
+* Test register ($F0) is not implemented.
+
+* Echo buffer can overwrite IPL ROM area, and does not correctly update
+extra RAM there.
+
+
+To Do
+-----
+* I'd like feedback on the interface and any ways to improve it. In
+particular, the differing features between the accurate and fast DSP
+emulators might make it harder to cleanly switch between them without
+modifying source code.
+
+* Finish thorough tests on SMP memory access times.
+
+* Finish thorough tests on SMP instruction behavior (flags, registers).
+
+* Finish thorough tests on SMP timers.
+
+* Finish power-up and reset behavior testing.
+
+* Come up with best starting conditions to play an SPC and implement in
+hardware SNES SPC player for verification.
+
+
+Thanks
+------
+Thanks to Anti-Resonance's SPC2ROM and help getting SPCs playing on my
+SNES in the first place, then Brad Martin's openspc and Chris Moeller's
+openspc++ C++ adaptation, giving me a good SPC emulator to start with
+several years ago. Thanks to Richard Bannister, Mahendra Tallur, Shazz,
+nenolod, theHobbit, Johan Samuelsson, nes6502, and Micket for helping
+test my Game_Music_Emu library. Thanks to hcs for help in converting to
+C for the Rockbox port. Thanks to byuu (bsnes author) and pagefault and
+Nach (zsnes team) for testing and using my new rewritten DSP in their
+emulators. Thanks to anomie for his good SNES documentation and
+discussions with me to keep it up to date with my latest findings.

+
+///////////   MEMORY ALLOCATION
+
+// normally stb_vorbis uses malloc() to allocate memory at startup,
+// and alloca() to allocate temporary memory during a frame on the
+// stack. (Memory consumption will depend on the amount of setup
+// data in the file and how you set the compile flags for speed
+// vs. size. In my test files the maximal-size usage is ~150KB.)
+//
+// You can modify the wrapper functions in the source (setup_malloc,
+// setup_temp_malloc, temp_malloc) to change this behavior, or you
+// can use a simpler allocation model: you pass in a buffer from
+// which stb_vorbis will allocate _all_ its memory (including the
+// temp memory). "open" may fail with a VORBIS_outofmem if you
+// do not pass in enough data; there is no way to determine how
+// much you do need except to succeed (at which point you can
+// query get_info to find the exact amount required. yes I know
+// this is lame).

+// If you pass in a non-NULL buffer of the type below, allocation
+// will occur from it as described above. Otherwise just pass NULL
+// to use malloc()/alloca()

+
+/*
+1. Introduction
+===============
+miniaudio is a single file library for audio playback and capture. To use it, do the following in one .c file:
+
+    ```c
+    #define MINIAUDIO_IMPLEMENTATION
+    #include "miniaudio.h"
+    ```
+
+You can do `#include "miniaudio.h"` in other parts of the program just like any other header.
+
+miniaudio uses the concept of a "device" as the abstraction for physical devices. The idea is that you choose a physical device to emit or capture audio from,
+and then move data to/from the device when miniaudio tells you to. Data is delivered to and from devices asynchronously via a callback which you specify when
+initializing the device.
+
+When initializing the device you first need to configure it. The device configuration allows you to specify things like the format of the data delivered via
+the callback, the size of the internal buffer and the ID of the device you want to emit or capture audio from.
+
+Once you have the device configuration set up you can initialize the device. When initializing a device you need to allocate memory for the device object
+beforehand. This gives the application complete control over how the memory is allocated. In the example below we initialize a playback device on the stack,
+but you could allocate it on the heap if that suits your situation better.
+
+    ```c
+    void data_callback(ma_device* pDevice, void* pOutput, const void* pInput, ma_uint32 frameCount)
+    {
+        // In playback mode copy data to pOutput. In capture mode read data from pInput. In full-duplex mode, both
+        // pOutput and pInput will be valid and you can move data from pInput into pOutput. Never process more than
+        // frameCount frames.
+    }
+
+    int main()
+    {
+        ma_device_config config = ma_device_config_init(ma_device_type_playback);
+        config.playback.format   = ma_format_f32;   // Set to ma_format_unknown to use the device's native format.
+        config.playback.channels = 2;               // Set to 0 to use the device's native channel count.
+        config.sampleRate        = 48000;           // Set to 0 to use the device's native sample rate.
+        config.dataCallback      = data_callback;   // This function will be called when miniaudio needs more data.
+        config.pUserData         = pMyCustomData;   // Can be accessed from the device object (device.pUserData).
+
+        ma_device device;
+        if (ma_device_init(NULL, &config, &device) != MA_SUCCESS) {
+            return -1;  // Failed to initialize the device.
+        }
+
+        ma_device_start(&device);     // The device is sleeping by default so you'll need to start it manually.
+
+        // Do something here. Probably your program's main loop.
+
+        ma_device_uninit(&device);    // This will stop the device so no need to do that manually.
+        return 0;
+    }
+    ```
+
+In the example above, `data_callback()` is where audio data is written and read from the device. The idea is in playback mode you cause sound to be emitted
+from the speakers by writing audio data to the output buffer (`pOutput` in the example). In capture mode you read data from the input buffer (`pInput`) to
+extract sound captured by the microphone. The `frameCount` parameter tells you how many frames can be written to the output buffer and read from the input
+buffer. A "frame" is one sample for each channel. For example, in a stereo stream (2 channels), one frame is 2 samples: one for the left, one for the right.
+The channel count is defined by the device config. The size in bytes of an individual sample is defined by the sample format which is also specified in the
+device config. Multi-channel audio data is always interleaved, which means the samples for each frame are stored next to each other in memory. For example, in
+a stereo stream the first pair of samples will be the left and right samples for the first frame, the second pair of samples will be the left and right samples
+for the second frame, etc.
+
+The configuration of the device is defined by the `ma_device_config` structure. The config object is always initialized with `ma_device_config_init()`. It's
+important to always initialize the config with this function as it initializes it with logical defaults and ensures your program doesn't break when new members
+are added to the `ma_device_config` structure. The example above uses a fairly simple and standard device configuration. The call to `ma_device_config_init()`
+takes a single parameter, which is whether or not the device is a playback, capture, duplex or loopback device (loopback devices are not supported on all
+backends). The `config.playback.format` member sets the sample format which can be one of the following (all formats are native-endian):
+
+    +---------------+----------------------------------------+---------------------------+
+    | Symbol        | Description                            | Range                     |
+    +---------------+----------------------------------------+---------------------------+
+    | ma_format_f32 | 32-bit floating point                  | [-1, 1]                   |
+    | ma_format_s16 | 16-bit signed integer                  | [-32768, 32767]           |
+    | ma_format_s24 | 24-bit signed integer (tightly packed) | [-8388608, 8388607]       |
+    | ma_format_s32 | 32-bit signed integer                  | [-2147483648, 2147483647] |
+    | ma_format_u8  | 8-bit unsigned integer                 | [0, 255]                  |
+    +---------------+----------------------------------------+---------------------------+
+
+The `config.playback.channels` member sets the number of channels to use with the device. The channel count cannot exceed MA_MAX_CHANNELS. The
+`config.sampleRate` member sets the sample rate (which must be the same for both playback and capture in full-duplex configurations). This is usually set to
+44100 or 48000, but can be set to anything. It's recommended to keep this between 8000 and 384000, however.
+
+Note that leaving the format, channel count and/or sample rate at their default values will result in the internal device's native configuration being used
+which is useful if you want to avoid the overhead of miniaudio's automatic data conversion.
+
+In addition to the sample format, channel count and sample rate, the data callback and user data pointer are also set via the config. The user data pointer is
+not passed into the callback as a parameter, but is instead set to the `pUserData` member of `ma_device` which you can access directly since all miniaudio
+structures are transparent.
+
+Initializing the device is done with `ma_device_init()`. This will return a result code telling you what went wrong, if anything. On success it will return
+`MA_SUCCESS`. After initialization is complete the device will be in a stopped state. To start it, use `ma_device_start()`. Uninitializing the device will stop
+it, which is what the example above does, but you can also stop the device with `ma_device_stop()`. To resume the device simply call `ma_device_start()` again.
+Note that it's important to never stop or start the device from inside the callback. This will result in a deadlock. Instead you set a variable or signal an
+event indicating that the device needs to stop and handle it in a different thread. The following APIs must never be called inside the callback:
+
+    ```c
+    ma_device_init()
+    ma_device_init_ex()
+    ma_device_uninit()
+    ma_device_start()
+    ma_device_stop()
+    ```
+
+You must never try uninitializing and reinitializing a device inside the callback. You must also never try to stop and start it from inside the callback. There
+are a few other things you shouldn't do in the callback depending on your requirements, however this isn't so much a thread-safety thing, but rather a
+real-time processing thing which is beyond the scope of this introduction.
+
+The example above demonstrates the initialization of a playback device, but it works exactly the same for capture. All you need to do is change the device type
+from `ma_device_type_playback` to `ma_device_type_capture` when setting up the config, like so:
+
+    ```c
+    ma_device_config config = ma_device_config_init(ma_device_type_capture);
+    config.capture.format   = MY_FORMAT;
+    config.capture.channels = MY_CHANNEL_COUNT;
+    ```
+
+In the data callback you just read from the input buffer (`pInput` in the example above) and leave the output buffer alone (it will be set to NULL when the
+device type is set to `ma_device_type_capture`).
+
+These are the available device types and how you should handle the buffers in the callback:
+
+    +-------------------------+--------------------------------------------------------+
+    | Device Type             | Callback Behavior                                      |
+    +-------------------------+--------------------------------------------------------+
+    | ma_device_type_playback | Write to output buffer, leave input buffer untouched.  |
+    | ma_device_type_capture  | Read from input buffer, leave output buffer untouched. |
+    | ma_device_type_duplex   | Read from input buffer, write to output buffer.        |
+    | ma_device_type_loopback | Read from input buffer, leave output buffer untouched. |
+    +-------------------------+--------------------------------------------------------+
+
+You will notice in the example above that the sample format and channel count is specified separately for playback and capture. This is to support different
+data formats between the playback and capture devices in a full-duplex system. An example may be that you want to capture audio data as a monaural stream (one
+channel), but output sound to a stereo speaker system. Note that if you use different formats between playback and capture in a full-duplex configuration you
+will need to convert the data yourself. There are functions available to help you do this which will be explained later.
+
+The example above did not specify a physical device to connect to which means it will use the operating system's default device. If you have multiple physical
+devices connected and you want to use a specific one you will need to specify the device ID in the configuration, like so:
+
+    ```c
+    config.playback.pDeviceID = pMyPlaybackDeviceID;    // Only if requesting a playback or duplex device.
+    config.capture.pDeviceID = pMyCaptureDeviceID;      // Only if requesting a capture, duplex or loopback device.
+    ```
+
+To retrieve the device ID you will need to perform device enumeration, however this requires the use of a new concept called the "context". Conceptually
+speaking the context sits above the device. There is one context to many devices. The purpose of the context is to represent the backend at a more global level
+and to perform operations outside the scope of an individual device. Mainly it is used for performing run-time linking against backend libraries, initializing
+backends and enumerating devices. The example below shows how to enumerate devices.
+
+    ```c
+    ma_context context;
+    if (ma_context_init(NULL, 0, NULL, &context) != MA_SUCCESS) {
+        // Error.
+    }
+
+    ma_device_info* pPlaybackInfos;
+    ma_uint32 playbackCount;
+    ma_device_info* pCaptureInfos;
+    ma_uint32 captureCount;
+    if (ma_context_get_devices(&context, &pPlaybackInfos, &playbackCount, &pCaptureInfos, &captureCount) != MA_SUCCESS) {
+        // Error.
+    }
+
+    // Loop over each device info and do something with it. Here we just print the name with their index. You may want
+    // to give the user the opportunity to choose which device they'd prefer.
+    for (ma_uint32 iDevice = 0; iDevice < playbackCount; iDevice += 1) {
+        printf("%d - %s\n", iDevice, pPlaybackInfos[iDevice].name);
+    }
+
+    ma_device_config config = ma_device_config_init(ma_device_type_playback);
+    config.playback.pDeviceID = &pPlaybackInfos[chosenPlaybackDeviceIndex].id;
+    config.playback.format    = MY_FORMAT;
+    config.playback.channels  = MY_CHANNEL_COUNT;
+    config.sampleRate         = MY_SAMPLE_RATE;
+    config.dataCallback       = data_callback;
+    config.pUserData          = pMyCustomData;
+
+    ma_device device;
+    if (ma_device_init(&context, &config, &device) != MA_SUCCESS) {
+        // Error
+    }
+
+    ...
+
+    ma_device_uninit(&device);
+    ma_context_uninit(&context);
+    ```
+
+The first thing we do in this example is initialize a `ma_context` object with `ma_context_init()`. The first parameter is a pointer to a list of `ma_backend`
+values which are used to override the default backend priorities. When this is NULL, as in this example, miniaudio's default priorities are used. The second
+parameter is the number of backends listed in the array pointed to by the first parameter. The third parameter is a pointer to a `ma_context_config` object
+which can be NULL, in which case defaults are used. The context configuration is used for setting the logging callback, custom memory allocation callbacks,
+user-defined data and some backend-specific configurations.
+
+Once the context has been initialized you can enumerate devices. In the example above we use the simpler `ma_context_get_devices()`, however you can also use a
+callback for handling devices by using `ma_context_enumerate_devices()`. When using `ma_context_get_devices()` you provide a pointer to a pointer that will,
+upon output, be set to a pointer to a buffer containing a list of `ma_device_info` structures. You also provide a pointer to an unsigned integer that will
+receive the number of items in the returned buffer. Do not free the returned buffers as their memory is managed internally by miniaudio.
+
+The `ma_device_info` structure contains an `id` member which is the ID you pass to the device config. It also contains the name of the device which is useful
+for presenting a list of devices to the user via the UI.
+
+When creating your own context you will want to pass it to `ma_device_init()` when initializing the device. Passing in NULL, like we do in the first example,
+will result in miniaudio creating the context for you, which you don't want to do since you've already created a context. Note that internally the context is
+only tracked by it's pointer which means you must not change the location of the `ma_context` object. If this is an issue, consider using `malloc()` to
+allocate memory for the context.
+
+
+
+2. Building
+===========
+miniaudio should work cleanly out of the box without the need to download or install any dependencies. See below for platform-specific details.
+
+
+2.1. Windows
+------------
+The Windows build should compile cleanly on all popular compilers without the need to configure any include paths nor link to any libraries.
+
+2.2. macOS and iOS
+------------------
+The macOS build should compile cleanly without the need to download any dependencies nor link to any libraries or frameworks. The iOS build needs to be
+compiled as Objective-C and will need to link the relevant frameworks but should compile cleanly out of the box with Xcode. Compiling through the command line
+requires linking to `-lpthread` and `-lm`.
+
+Due to the way miniaudio links to frameworks at runtime, your application may not pass Apple's notarization process. To fix this there are two options. The
+first is to use the `MA_NO_RUNTIME_LINKING` option, like so:
+
+    ```c
+    #ifdef __APPLE__
+        #define MA_NO_RUNTIME_LINKING
+    #endif 
+    #define MINIAUDIO_IMPLEMENTATION
+    #include "miniaudio.h"
+    ```
+
+This will require linking with `-framework CoreFoundation -framework CoreAudio -framework AudioUnit`. Alternatively, if you would rather keep using runtime
+linking you can add the following to your entitlements.xcent file:
+
+    ```
+    <key>com.apple.security.cs.allow-dyld-environment-variables</key>
+    <true/>
+    <key>com.apple.security.cs.allow-unsigned-executable-memory</key>
+    <true/>
+    ```
+
+
+2.3. Linux
+----------
+The Linux build only requires linking to `-ldl`, `-lpthread` and `-lm`. You do not need any development packages.
+
+2.4. BSD
+--------
+The BSD build only requires linking to `-lpthread` and `-lm`. NetBSD uses audio(4), OpenBSD uses sndio and FreeBSD uses OSS.
+
+2.5. Android
+------------
+AAudio is the highest priority backend on Android. This should work out of the box without needing any kind of compiler configuration. Support for AAudio
+starts with Android 8 which means older versions will fall back to OpenSL|ES which requires API level 16+.
+
+2.6. Emscripten
+---------------
+The Emscripten build emits Web Audio JavaScript directly and should compile cleanly out of the box. You cannot use -std=c* compiler flags, nor -ansi.
+
+
+2.7. Build Options
+------------------
+`#define` these options before including miniaudio.h.
+
+    +----------------------+----------------------------------------------------------------------------------------------------------------------------------+

+
+
+3. Definitions
+==============
+This section defines common terms used throughout miniaudio. Unfortunately there is often ambiguity in the use of terms throughout the audio space, so this
+section is intended to clarify how miniaudio uses each term.
+
+3.1. Sample
+-----------
+A sample is a single unit of audio data. If the sample format is f32, then one sample is one 32-bit floating point number.
+
+3.2. Frame / PCM Frame
+----------------------
+A frame is a group of samples equal to the number of channels. For a stereo stream a frame is 2 samples, a mono frame is 1 sample, a 5.1 surround sound frame
+is 6 samples, etc. The terms "frame" and "PCM frame" are the same thing in miniaudio. Note that this is different to a compressed frame. If ever miniaudio
+needs to refer to a compressed frame, such as a FLAC frame, it will always clarify what it's referring to with something like "FLAC frame".
+
+3.3. Channel
+------------
+A stream of monaural audio that is emitted from an individual speaker in a speaker system, or received from an individual microphone in a microphone system. A
+stereo stream has two channels (a left channel, and a right channel), a 5.1 surround sound system has 6 channels, etc. Some audio systems refer to a channel as
+a complex audio stream that's mixed with other channels to produce the final mix - this is completely different to miniaudio's use of the term "channel" and
+should not be confused.
+
+3.4. Sample Rate
+----------------
+The sample rate in miniaudio is always expressed in Hz, such as 44100, 48000, etc. It's the number of PCM frames that are processed per second.
+
+3.5. Formats
+------------
+Throughout miniaudio you will see references to different sample formats:
+
+    +---------------+----------------------------------------+---------------------------+
+    | Symbol        | Description                            | Range                     |
+    +---------------+----------------------------------------+---------------------------+
+    | ma_format_f32 | 32-bit floating point                  | [-1, 1]                   |
+    | ma_format_s16 | 16-bit signed integer                  | [-32768, 32767]           |
+    | ma_format_s24 | 24-bit signed integer (tightly packed) | [-8388608, 8388607]       |
+    | ma_format_s32 | 32-bit signed integer                  | [-2147483648, 2147483647] |
+    | ma_format_u8  | 8-bit unsigned integer                 | [0, 255]                  |
+    +---------------+----------------------------------------+---------------------------+
+
+All formats are native-endian.
+
+
+
+4. Decoding
+===========
+The `ma_decoder` API is used for reading audio files. The following formats are supported:
+
+    +---------+------------------+----------+
+    | Format  | Decoding Backend | Built-In |
+    +---------+------------------+----------+
+    | WAV     | dr_wav           | Yes      |
+    | MP3     | dr_mp3           | Yes      |
+    | FLAC    | dr_flac          | Yes      |
+    | Vorbis  | stb_vorbis       | No       |
+    +---------+------------------+----------+
+
+Vorbis is supported via stb_vorbis which can be enabled by including the header section before the implementation of miniaudio, like the following:
+
+    ```c
+    #define STB_VORBIS_HEADER_ONLY
+    #include "extras/stb_vorbis.c"    // Enables Vorbis decoding.
+
+    #define MINIAUDIO_IMPLEMENTATION
+    #include "miniaudio.h"
+
+    // The stb_vorbis implementation must come after the implementation of miniaudio.
+    #undef STB_VORBIS_HEADER_ONLY
+    #include "extras/stb_vorbis.c"
+    ```
+
+A copy of stb_vorbis is included in the "extras" folder in the miniaudio repository (https://github.com/mackron/miniaudio).
+
+Built-in decoders are amalgamated into the implementation section of miniaudio. You can disable the built-in decoders by specifying one or more of the
+following options before the miniaudio implementation:
+
+    ```c
+    #define MA_NO_WAV
+    #define MA_NO_MP3
+    #define MA_NO_FLAC
+    ```
+
+Disabling built-in decoding libraries is useful if you use these libraries independantly of the `ma_decoder` API.

+A decoder can be initialized from a file with `ma_decoder_init_file()`, a block of memory with `ma_decoder_init_memory()`, or from data delivered via callbacks
+with `ma_decoder_init()`. Here is an example for loading a decoder from a file:
+
+    ```c
+    ma_decoder decoder;
+    ma_result result = ma_decoder_init_file("MySong.mp3", NULL, &decoder);
+    if (result != MA_SUCCESS) {
+        return false;   // An error occurred.
+    }
+
+    ...
+
+    ma_decoder_uninit(&decoder);
+    ```
+
+When initializing a decoder, you can optionally pass in a pointer to a ma_decoder_config object (the NULL argument in the example above) which allows you to
+configure the output format, channel count, sample rate and channel map:
+
+    ```c
+    ma_decoder_config config = ma_decoder_config_init(ma_format_f32, 2, 48000);
+    ```
+
+When passing in NULL for decoder config in `ma_decoder_init*()`, the output format will be the same as that defined by the decoding backend.
+
+Data is read from the decoder as PCM frames. This will return the number of PCM frames actually read. If the return value is less than the requested number of
+PCM frames it means you've reached the end:
+
+    ```c
+    ma_uint64 framesRead = ma_decoder_read_pcm_frames(pDecoder, pFrames, framesToRead);
+    if (framesRead < framesToRead) {
+        // Reached the end.
+    }
+    ```
+
+You can also seek to a specific frame like so:
+
+    ```c
+    ma_result result = ma_decoder_seek_to_pcm_frame(pDecoder, targetFrame);
+    if (result != MA_SUCCESS) {
+        return false;   // An error occurred.
+    }
+    ```
+
+If you want to loop back to the start, you can simply seek back to the first PCM frame:
+
+    ```c
+    ma_decoder_seek_to_pcm_frame(pDecoder, 0);
+    ```
+
+When loading a decoder, miniaudio uses a trial and error technique to find the appropriate decoding backend. This can be unnecessarily inefficient if the type
+is already known. In this case you can use the `_wav`, `_mp3`, etc. varients of the aforementioned initialization APIs:
+
+    ```c
+    ma_decoder_init_wav()
+    ma_decoder_init_mp3()
+    ma_decoder_init_memory_wav()
+    ma_decoder_init_memory_mp3()
+    ma_decoder_init_file_wav()
+    ma_decoder_init_file_mp3()
+    etc.
+    ```
+
+The `ma_decoder_init_file()` API will try using the file extension to determine which decoding backend to prefer.
+
+
+
+5. Encoding
+===========
+The `ma_encoding` API is used for writing audio files. The only supported output format is WAV which is achieved via dr_wav which is amalgamated into the
+implementation section of miniaudio. This can be disabled by specifying the following option before the implementation of miniaudio:
+
+    ```c
+    #define MA_NO_WAV
+    ```
+
+An encoder can be initialized to write to a file with `ma_encoder_init_file()` or from data delivered via callbacks with `ma_encoder_init()`. Below is an
+example for initializing an encoder to output to a file.
+
+    ```c
+    ma_encoder_config config = ma_encoder_config_init(ma_resource_format_wav, FORMAT, CHANNELS, SAMPLE_RATE);
+    ma_encoder encoder;
+    ma_result result = ma_encoder_init_file("my_file.wav", &config, &encoder);
+    if (result != MA_SUCCESS) {
+        // Error
+    }
+
+    ...
+
+    ma_encoder_uninit(&encoder);
+    ```
+
+When initializing an encoder you must specify a config which is initialized with `ma_encoder_config_init()`. Here you must specify the file type, the output
+sample format, output channel count and output sample rate. The following file types are supported:
+
+    +------------------------+-------------+
+    | Enum                   | Description |
+    +------------------------+-------------+
+    | ma_resource_format_wav | WAV         |
+    +------------------------+-------------+
+
+If the format, channel count or sample rate is not supported by the output file type an error will be returned. The encoder will not perform data conversion so
+you will need to convert it before outputting any audio data. To output audio data, use `ma_encoder_write_pcm_frames()`, like in the example below:
+
+    ```c
+    framesWritten = ma_encoder_write_pcm_frames(&encoder, pPCMFramesToWrite, framesToWrite);
+    ```
+
+Encoders must be uninitialized with `ma_encoder_uninit()`.
+
+
+6. Data Conversion
+==================
+A data conversion API is included with miniaudio which supports the majority of data conversion requirements. This supports conversion between sample formats,
+channel counts (with channel mapping) and sample rates.
+
+
+6.1. Sample Format Conversion
+-----------------------------
+Conversion between sample formats is achieved with the `ma_pcm_*_to_*()`, `ma_pcm_convert()` and `ma_convert_pcm_frames_format()` APIs. Use `ma_pcm_*_to_*()`
+to convert between two specific formats. Use `ma_pcm_convert()` to convert based on a `ma_format` variable. Use `ma_convert_pcm_frames_format()` to convert
+PCM frames where you want to specify the frame count and channel count as a variable instead of the total sample count.
+
+
+6.1.1. Dithering
+----------------
+Dithering can be set using the ditherMode parameter.
+
+The different dithering modes include the following, in order of efficiency:
+
+    +-----------+--------------------------+
+    | Type      | Enum Token               |
+    +-----------+--------------------------+
+    | None      | ma_dither_mode_none      |
+    | Rectangle | ma_dither_mode_rectangle |
+    | Triangle  | ma_dither_mode_triangle  |
+    +-----------+--------------------------+
+
+Note that even if the dither mode is set to something other than `ma_dither_mode_none`, it will be ignored for conversions where dithering is not needed.
+Dithering is available for the following conversions:
+
+    ```
+    s16 -> u8
+    s24 -> u8
+    s32 -> u8
+    f32 -> u8
+    s24 -> s16
+    s32 -> s16
+    f32 -> s16
+    ```
+
+Note that it is not an error to pass something other than ma_dither_mode_none for conversions where dither is not used. It will just be ignored.
+
+
+
+6.2. Channel Conversion
+-----------------------
+Channel conversion is used for channel rearrangement and conversion from one channel count to another. The `ma_channel_converter` API is used for channel
+conversion. Below is an example of initializing a simple channel converter which converts from mono to stereo.
+
+    ```c
+    ma_channel_converter_config config = ma_channel_converter_config_init(
+        ma_format,                      // Sample format
+        1,                              // Input channels
+        NULL,                           // Input channel map
+        2,                              // Output channels
+        NULL,                           // Output channel map
+        ma_channel_mix_mode_default);   // The mixing algorithm to use when combining channels.
+
+    result = ma_channel_converter_init(&config, &converter);
+    if (result != MA_SUCCESS) {
+        // Error.
+    }
+    ```
+
+To perform the conversion simply call `ma_channel_converter_process_pcm_frames()` like so:
+
+    ```c
+    ma_result result = ma_channel_converter_process_pcm_frames(&converter, pFramesOut, pFramesIn, frameCount);
+    if (result != MA_SUCCESS) {
+        // Error.
+    }
+    ```
+
+It is up to the caller to ensure the output buffer is large enough to accomodate the new PCM frames.
+
+Input and output PCM frames are always interleaved. Deinterleaved layouts are not supported.
+
+
+6.2.1. Channel Mapping
+----------------------
+In addition to converting from one channel count to another, like the example above, the channel converter can also be used to rearrange channels. When
+initializing the channel converter, you can optionally pass in channel maps for both the input and output frames. If the channel counts are the same, and each
+channel map contains the same channel positions with the exception that they're in a different order, a simple shuffling of the channels will be performed. If,
+however, there is not a 1:1 mapping of channel positions, or the channel counts differ, the input channels will be mixed based on a mixing mode which is
+specified when initializing the `ma_channel_converter_config` object.
+
+When converting from mono to multi-channel, the mono channel is simply copied to each output channel. When going the other way around, the audio of each output
+channel is simply averaged and copied to the mono channel.
+
+In more complicated cases blending is used. The `ma_channel_mix_mode_simple` mode will drop excess channels and silence extra channels. For example, converting
+from 4 to 2 channels, the 3rd and 4th channels will be dropped, whereas converting from 2 to 4 channels will put silence into the 3rd and 4th channels.
+
+The `ma_channel_mix_mode_rectangle` mode uses spacial locality based on a rectangle to compute a simple distribution between input and output. Imagine sitting
+in the middle of a room, with speakers on the walls representing channel positions. The MA_CHANNEL_FRONT_LEFT position can be thought of as being in the corner
+of the front and left walls.
+
+Finally, the `ma_channel_mix_mode_custom_weights` mode can be used to use custom user-defined weights. Custom weights can be passed in as the last parameter of
+`ma_channel_converter_config_init()`.
+
+Predefined channel maps can be retrieved with `ma_get_standard_channel_map()`. This takes a `ma_standard_channel_map` enum as it's first parameter, which can
+be one of the following:
+
+    +-----------------------------------+-----------------------------------------------------------+
+    | Name                              | Description                                               |

+    +---------------+---------------------------------+
+
+
+
+6.3. Resampling
+---------------
+Resampling is achieved with the `ma_resampler` object. To create a resampler object, do something like the following:
+
+    ```c
+    ma_resampler_config config = ma_resampler_config_init(
+        ma_format_s16,
+        channels,
+        sampleRateIn,
+        sampleRateOut,
+        ma_resample_algorithm_linear);
+
+    ma_resampler resampler;
+    ma_result result = ma_resampler_init(&config, &resampler);
+    if (result != MA_SUCCESS) {
+        // An error occurred...
+    }
+    ```
+
+Do the following to uninitialize the resampler:
+
+    ```c
+    ma_resampler_uninit(&resampler);
+    ```
+
+The following example shows how data can be processed
+
+    ```c
+    ma_uint64 frameCountIn  = 1000;
+    ma_uint64 frameCountOut = 2000;
+    ma_result result = ma_resampler_process_pcm_frames(&resampler, pFramesIn, &frameCountIn, pFramesOut, &frameCountOut);
+    if (result != MA_SUCCESS) {
+        // An error occurred...
+    }
+
+    // At this point, frameCountIn contains the number of input frames that were consumed and frameCountOut contains the
+    // number of output frames written.
+    ```
+
+To initialize the resampler you first need to set up a config (`ma_resampler_config`) with `ma_resampler_config_init()`. You need to specify the sample format
+you want to use, the number of channels, the input and output sample rate, and the algorithm.
+
+The sample format can be either `ma_format_s16` or `ma_format_f32`. If you need a different format you will need to perform pre- and post-conversions yourself
+where necessary. Note that the format is the same for both input and output. The format cannot be changed after initialization.
+
+The resampler supports multiple channels and is always interleaved (both input and output). The channel count cannot be changed after initialization.
+
+The sample rates can be anything other than zero, and are always specified in hertz. They should be set to something like 44100, etc. The sample rate is the
+only configuration property that can be changed after initialization.
+
+The miniaudio resampler supports multiple algorithms:
+
+    +-----------+------------------------------+
+    | Algorithm | Enum Token                   |
+    +-----------+------------------------------+
+    | Linear    | ma_resample_algorithm_linear |
+    | Speex     | ma_resample_algorithm_speex  |
+    +-----------+------------------------------+
+
+Because Speex is not public domain it is strictly opt-in and the code is stored in separate files. if you opt-in to the Speex backend you will need to consider
+it's license, the text of which can be found in it's source files in "extras/speex_resampler". Details on how to opt-in to the Speex resampler is explained in
+the Speex Resampler section below.
+
+The algorithm cannot be changed after initialization.
+
+Processing always happens on a per PCM frame basis and always assumes interleaved input and output. De-interleaved processing is not supported. To process
+frames, use `ma_resampler_process_pcm_frames()`. On input, this function takes the number of output frames you can fit in the output buffer and the number of
+input frames contained in the input buffer. On output these variables contain the number of output frames that were written to the output buffer and the
+number of input frames that were consumed in the process. You can pass in NULL for the input buffer in which case it will be treated as an infinitely large
+buffer of zeros. The output buffer can also be NULL, in which case the processing will be treated as seek.
+
+The sample rate can be changed dynamically on the fly. You can change this with explicit sample rates with `ma_resampler_set_rate()` and also with a decimal
+ratio with `ma_resampler_set_rate_ratio()`. The ratio is in/out.
+
+Sometimes it's useful to know exactly how many input frames will be required to output a specific number of frames. You can calculate this with
+`ma_resampler_get_required_input_frame_count()`. Likewise, it's sometimes useful to know exactly how many frames would be output given a certain number of
+input frames. You can do this with `ma_resampler_get_expected_output_frame_count()`.
+
+Due to the nature of how resampling works, the resampler introduces some latency. This can be retrieved in terms of both the input rate and the output rate
+with `ma_resampler_get_input_latency()` and `ma_resampler_get_output_latency()`.
+
+
+6.3.1. Resampling Algorithms
+----------------------------
+The choice of resampling algorithm depends on your situation and requirements. The linear resampler is the most efficient and has the least amount of latency,
+but at the expense of poorer quality. The Speex resampler is higher quality, but slower with more latency. It also performs several heap allocations internally
+for memory management.
+
+
+6.3.1.1. Linear Resampling
+--------------------------
+The linear resampler is the fastest, but comes at the expense of poorer quality. There is, however, some control over the quality of the linear resampler which
+may make it a suitable option depending on your requirements.
+
+The linear resampler performs low-pass filtering before or after downsampling or upsampling, depending on the sample rates you're converting between. When
+decreasing the sample rate, the low-pass filter will be applied before downsampling. When increasing the rate it will be performed after upsampling. By default
+a fourth order low-pass filter will be applied. This can be configured via the `lpfOrder` configuration variable. Setting this to 0 will disable filtering.
+
+The low-pass filter has a cutoff frequency which defaults to half the sample rate of the lowest of the input and output sample rates (Nyquist Frequency). This
+can be controlled with the `lpfNyquistFactor` config variable. This defaults to 1, and should be in the range of 0..1, although a value of 0 does not make
+sense and should be avoided. A value of 1 will use the Nyquist Frequency as the cutoff. A value of 0.5 will use half the Nyquist Frequency as the cutoff, etc.
+Values less than 1 will result in more washed out sound due to more of the higher frequencies being removed. This config variable has no impact on performance
+and is a purely perceptual configuration.
+
+The API for the linear resampler is the same as the main resampler API, only it's called `ma_linear_resampler`.
+
+
+6.3.1.2. Speex Resampling
+-------------------------
+The Speex resampler is made up of third party code which is released under the BSD license. Because it is licensed differently to miniaudio, which is public
+domain, it is strictly opt-in and all of it's code is stored in separate files. If you opt-in to the Speex resampler you must consider the license text in it's
+source files. To opt-in, you must first #include the following file before the implementation of miniaudio.h:
+
+    ```c
+    #include "extras/speex_resampler/ma_speex_resampler.h"
+    ```
+
+Both the header and implementation is contained within the same file. The implementation can be included in your program like so:
+
+    ```c
+    #define MINIAUDIO_SPEEX_RESAMPLER_IMPLEMENTATION
+    #include "extras/speex_resampler/ma_speex_resampler.h"
+    ```
+
+Note that even if you opt-in to the Speex backend, miniaudio won't use it unless you explicitly ask for it in the respective config of the object you are
+initializing. If you try to use the Speex resampler without opting in, initialization of the `ma_resampler` object will fail with `MA_NO_BACKEND`.
+
+The only configuration option to consider with the Speex resampler is the `speex.quality` config variable. This is a value between 0 and 10, with 0 being
+the fastest with the poorest quality and 10 being the slowest with the highest quality. The default value is 3.
+
+
+
+6.4. General Data Conversion
+----------------------------
+The `ma_data_converter` API can be used to wrap sample format conversion, channel conversion and resampling into one operation. This is what miniaudio uses
+internally to convert between the format requested when the device was initialized and the format of the backend's native device. The API for general data
+conversion is very similar to the resampling API. Create a `ma_data_converter` object like this:
+
+    ```c
+    ma_data_converter_config config = ma_data_converter_config_init(
+        inputFormat,
+        outputFormat,
+        inputChannels,
+        outputChannels,
+        inputSampleRate,
+        outputSampleRate
+    );
+
+    ma_data_converter converter;
+    ma_result result = ma_data_converter_init(&config, &converter);
+    if (result != MA_SUCCESS) {
+        // An error occurred...
+    }
+    ```
+
+In the example above we use `ma_data_converter_config_init()` to initialize the config, however there's many more properties that can be configured, such as
+channel maps and resampling quality. Something like the following may be more suitable depending on your requirements:
+
+    ```c
+    ma_data_converter_config config = ma_data_converter_config_init_default();
+    config.formatIn = inputFormat;
+    config.formatOut = outputFormat;
+    config.channelsIn = inputChannels;
+    config.channelsOut = outputChannels;
+    config.sampleRateIn = inputSampleRate;
+    config.sampleRateOut = outputSampleRate;
+    ma_get_standard_channel_map(ma_standard_channel_map_flac, config.channelCountIn, config.channelMapIn);
+    config.resampling.linear.lpfOrder = MA_MAX_FILTER_ORDER;
+    ```
+
+Do the following to uninitialize the data converter:
+
+    ```c
+    ma_data_converter_uninit(&converter);
+    ```
+
+The following example shows how data can be processed
+
+    ```c
+    ma_uint64 frameCountIn  = 1000;
+    ma_uint64 frameCountOut = 2000;
+    ma_result result = ma_data_converter_process_pcm_frames(&converter, pFramesIn, &frameCountIn, pFramesOut, &frameCountOut);
+    if (result != MA_SUCCESS) {
+        // An error occurred...
+    }
+
+    // At this point, frameCountIn contains the number of input frames that were consumed and frameCountOut contains the number
+    // of output frames written.
+    ```
+
+The data converter supports multiple channels and is always interleaved (both input and output). The channel count cannot be changed after initialization.
+
+Sample rates can be anything other than zero, and are always specified in hertz. They should be set to something like 44100, etc. The sample rate is the only
+configuration property that can be changed after initialization, but only if the `resampling.allowDynamicSampleRate` member of `ma_data_converter_config` is
+set to MA_TRUE. To change the sample rate, use `ma_data_converter_set_rate()` or `ma_data_converter_set_rate_ratio()`. The ratio must be in/out. The resampling
+algorithm cannot be changed after initialization.
+
+Processing always happens on a per PCM frame basis and always assumes interleaved input and output. De-interleaved processing is not supported. To process
+frames, use `ma_data_converter_process_pcm_frames()`. On input, this function takes the number of output frames you can fit in the output buffer and the number
+of input frames contained in the input buffer. On output these variables contain the number of output frames that were written to the output buffer and the
+number of input frames that were consumed in the process. You can pass in NULL for the input buffer in which case it will be treated as an infinitely large
+buffer of zeros. The output buffer can also be NULL, in which case the processing will be treated as seek.
+
+Sometimes it's useful to know exactly how many input frames will be required to output a specific number of frames. You can calculate this with
+`ma_data_converter_get_required_input_frame_count()`. Likewise, it's sometimes useful to know exactly how many frames would be output given a certain number of
+input frames. You can do this with `ma_data_converter_get_expected_output_frame_count()`.
+
+Due to the nature of how resampling works, the data converter introduces some latency if resampling is required. This can be retrieved in terms of both the
+input rate and the output rate with `ma_data_converter_get_input_latency()` and `ma_data_converter_get_output_latency()`.
+
+
+
+7. Filtering
+============
+
+7.1. Biquad Filtering
+---------------------
+Biquad filtering is achieved with the `ma_biquad` API. Example:
+
+    ```c
+    ma_biquad_config config = ma_biquad_config_init(ma_format_f32, channels, b0, b1, b2, a0, a1, a2);
+    ma_result result = ma_biquad_init(&config, &biquad);
+    if (result != MA_SUCCESS) {
+        // Error.
+    }
+
+    ...
+
+    ma_biquad_process_pcm_frames(&biquad, pFramesOut, pFramesIn, frameCount);
+    ```
+
+Biquad filtering is implemented using transposed direct form 2. The numerator coefficients are b0, b1 and b2, and the denominator coefficients are a0, a1 and
+a2. The a0 coefficient is required and coefficients must not be pre-normalized.
+
+Supported formats are `ma_format_s16` and `ma_format_f32`. If you need to use a different format you need to convert it yourself beforehand. When using
+`ma_format_s16` the biquad filter will use fixed point arithmetic. When using `ma_format_f32`, floating point arithmetic will be used.
+
+Input and output frames are always interleaved.
+
+Filtering can be applied in-place by passing in the same pointer for both the input and output buffers, like so:
+
+    ```c
+    ma_biquad_process_pcm_frames(&biquad, pMyData, pMyData, frameCount);
+    ```
+
+If you need to change the values of the coefficients, but maintain the values in the registers you can do so with `ma_biquad_reinit()`. This is useful if you
+need to change the properties of the filter while keeping the values of registers valid to avoid glitching. Do not use `ma_biquad_init()` for this as it will
+do a full initialization which involves clearing the registers to 0. Note that changing the format or channel count after initialization is invalid and will
+result in an error.
+
+
+7.2. Low-Pass Filtering
+-----------------------
+Low-pass filtering is achieved with the following APIs:
+
+    +---------+------------------------------------------+
+    | API     | Description                              |
+    +---------+------------------------------------------+
+    | ma_lpf1 | First order low-pass filter              |
+    | ma_lpf2 | Second order low-pass filter             |
+    | ma_lpf  | High order low-pass filter (Butterworth) |
+    +---------+------------------------------------------+
+
+Low-pass filter example:
+
+    ```c
+    ma_lpf_config config = ma_lpf_config_init(ma_format_f32, channels, sampleRate, cutoffFrequency, order);
+    ma_result result = ma_lpf_init(&config, &lpf);
+    if (result != MA_SUCCESS) {
+        // Error.
+    }
+
+    ...
+
+    ma_lpf_process_pcm_frames(&lpf, pFramesOut, pFramesIn, frameCount);
+    ```
+
+Supported formats are `ma_format_s16` and` ma_format_f32`. If you need to use a different format you need to convert it yourself beforehand. Input and output
+frames are always interleaved.
+
+Filtering can be applied in-place by passing in the same pointer for both the input and output buffers, like so:
+
+    ```c
+    ma_lpf_process_pcm_frames(&lpf, pMyData, pMyData, frameCount);
+    ```
+
+The maximum filter order is limited to MA_MAX_FILTER_ORDER which is set to 8. If you need more, you can chain first and second order filters together.
+
+    ```c
+    for (iFilter = 0; iFilter < filterCount; iFilter += 1) {
+        ma_lpf2_process_pcm_frames(&lpf2[iFilter], pMyData, pMyData, frameCount);
+    }
+    ```
+
+If you need to change the configuration of the filter, but need to maintain the state of internal registers you can do so with `ma_lpf_reinit()`. This may be
+useful if you need to change the sample rate and/or cutoff frequency dynamically while maintaing smooth transitions. Note that changing the format or channel
+count after initialization is invalid and will result in an error.
+
+The `ma_lpf` object supports a configurable order, but if you only need a first order filter you may want to consider using `ma_lpf1`. Likewise, if you only
+need a second order filter you can use `ma_lpf2`. The advantage of this is that they're lighter weight and a bit more efficient.
+
+If an even filter order is specified, a series of second order filters will be processed in a chain. If an odd filter order is specified, a first order filter
+will be applied, followed by a series of second order filters in a chain.
+
+
+7.3. High-Pass Filtering
+------------------------
+High-pass filtering is achieved with the following APIs:
+
+    +---------+-------------------------------------------+
+    | API     | Description                               |
+    +---------+-------------------------------------------+
+    | ma_hpf1 | First order high-pass filter              |
+    | ma_hpf2 | Second order high-pass filter             |
+    | ma_hpf  | High order high-pass filter (Butterworth) |
+    +---------+-------------------------------------------+
+
+High-pass filters work exactly the same as low-pass filters, only the APIs are called `ma_hpf1`, `ma_hpf2` and `ma_hpf`. See example code for low-pass filters
+for example usage.
+
+
+7.4. Band-Pass Filtering
+------------------------
+Band-pass filtering is achieved with the following APIs:
+
+    +---------+-------------------------------+
+    | API     | Description                   |
+    +---------+-------------------------------+
+    | ma_bpf2 | Second order band-pass filter |
+    | ma_bpf  | High order band-pass filter   |
+    +---------+-------------------------------+
+
+Band-pass filters work exactly the same as low-pass filters, only the APIs are called `ma_bpf2` and `ma_hpf`. See example code for low-pass filters for example
+usage. Note that the order for band-pass filters must be an even number which means there is no first order band-pass filter, unlike low-pass and high-pass
+filters.
+
+
+7.5. Notch Filtering
+--------------------
+Notch filtering is achieved with the following APIs:
+
+    +-----------+------------------------------------------+
+    | API       | Description                              |
+    +-----------+------------------------------------------+
+    | ma_notch2 | Second order notching filter             |
+    +-----------+------------------------------------------+
+
+
+7.6. Peaking EQ Filtering
+-------------------------
+Peaking filtering is achieved with the following APIs:
+
+    +----------+------------------------------------------+
+    | API      | Description                              |
+    +----------+------------------------------------------+
+    | ma_peak2 | Second order peaking filter              |
+    +----------+------------------------------------------+
+
+
+7.7. Low Shelf Filtering
+------------------------
+Low shelf filtering is achieved with the following APIs:
+
+    +-------------+------------------------------------------+
+    | API         | Description                              |
+    +-------------+------------------------------------------+
+    | ma_loshelf2 | Second order low shelf filter            |
+    +-------------+------------------------------------------+
+
+Where a high-pass filter is used to eliminate lower frequencies, a low shelf filter can be used to just turn them down rather than eliminate them entirely.
+
+
+7.8. High Shelf Filtering
+-------------------------
+High shelf filtering is achieved with the following APIs:
+
+    +-------------+------------------------------------------+
+    | API         | Description                              |
+    +-------------+------------------------------------------+
+    | ma_hishelf2 | Second order high shelf filter           |
+    +-------------+------------------------------------------+
+
+The high shelf filter has the same API as the low shelf filter, only you would use `ma_hishelf` instead of `ma_loshelf`. Where a low shelf filter is used to
+adjust the volume of low frequencies, the high shelf filter does the same thing for high frequencies.
+
+
+
+
+8. Waveform and Noise Generation
+================================
+
+8.1. Waveforms
+--------------
+miniaudio supports generation of sine, square, triangle and sawtooth waveforms. This is achieved with the `ma_waveform` API. Example:
+
+    ```c
+    ma_waveform_config config = ma_waveform_config_init(
+        FORMAT,
+        CHANNELS,
+        SAMPLE_RATE,
+        ma_waveform_type_sine,
+        amplitude,
+        frequency);
+
+    ma_waveform waveform;
+    ma_result result = ma_waveform_init(&config, &waveform);
+    if (result != MA_SUCCESS) {
+        // Error.
+    }
+
+    ...
+
+    ma_waveform_read_pcm_frames(&waveform, pOutput, frameCount);
+    ```
+
+The amplitude, frequency and sample rate can be changed dynamically with `ma_waveform_set_amplitude()`, `ma_waveform_set_frequency()` and
+`ma_waveform_set_sample_rate()` respectively.
+
+You can invert the waveform by setting the amplitude to a negative value. You can use this to control whether or not a sawtooth has a positive or negative
+ramp, for example.
+
+Below are the supported waveform types:
+
+    +---------------------------+
+    | Enum Name                 |
+    +---------------------------+
+    | ma_waveform_type_sine     |
+    | ma_waveform_type_square   |
+    | ma_waveform_type_triangle |
+    | ma_waveform_type_sawtooth |
+    +---------------------------+
+
+
+
+8.2. Noise
+----------
+miniaudio supports generation of white, pink and Brownian noise via the `ma_noise` API. Example:
+
+    ```c
+    ma_noise_config config = ma_noise_config_init(
+        FORMAT,
+        CHANNELS,
+        ma_noise_type_white,
+        SEED,
+        amplitude);
+
+    ma_noise noise;
+    ma_result result = ma_noise_init(&config, &noise);
+    if (result != MA_SUCCESS) {
+        // Error.
+    }
+
+    ...
+
+    ma_noise_read_pcm_frames(&noise, pOutput, frameCount);
+    ```
+
+The noise API uses simple LCG random number generation. It supports a custom seed which is useful for things like automated testing requiring reproducibility.
+Setting the seed to zero will default to MA_DEFAULT_LCG_SEED.
+
+By default, the noise API will use different values for different channels. So, for example, the left side in a stereo stream will be different to the right
+side. To instead have each channel use the same random value, set the `duplicateChannels` member of the noise config to true, like so:
+
+    ```c
+    config.duplicateChannels = MA_TRUE;
+    ```
+
+Below are the supported noise types.
+
+    +------------------------+
+    | Enum Name              |
+    +------------------------+
+    | ma_noise_type_white    |
+    | ma_noise_type_pink     |
+    | ma_noise_type_brownian |
+    +------------------------+
+
+
+
+9. Audio Buffers
+================
+miniaudio supports reading from a buffer of raw audio data via the `ma_audio_buffer` API. This can read from memory that's managed by the application, but
+can also handle the memory management for you internally. Memory management is flexible and should support most use cases.
+
+Audio buffers are initialised using the standard configuration system used everywhere in miniaudio:
+
+    ```c
+    ma_audio_buffer_config config = ma_audio_buffer_config_init(
+        format,
+        channels,
+        sizeInFrames,
+        pExistingData,
+        &allocationCallbacks);
+
+    ma_audio_buffer buffer;
+    result = ma_audio_buffer_init(&config, &buffer);
+    if (result != MA_SUCCESS) {
+        // Error.
+    }
+
+    ...
+
+    ma_audio_buffer_uninit(&buffer);
+    ```
+
+In the example above, the memory pointed to by `pExistingData` will _not_ be copied and is how an application can do self-managed memory allocation. If you
+would rather make a copy of the data, use `ma_audio_buffer_init_copy()`. To uninitialize the buffer, use `ma_audio_buffer_uninit()`.
+
+Sometimes it can be convenient to allocate the memory for the `ma_audio_buffer` structure _and_ the raw audio data in a contiguous block of memory. That is,
+the raw audio data will be located immediately after the `ma_audio_buffer` structure. To do this, use `ma_audio_buffer_alloc_and_init()`:
+
+    ```c
+    ma_audio_buffer_config config = ma_audio_buffer_config_init(
+        format,
+        channels,
+        sizeInFrames,
+        pExistingData,
+        &allocationCallbacks);
+
+    ma_audio_buffer* pBuffer
+    result = ma_audio_buffer_alloc_and_init(&config, &pBuffer);
+    if (result != MA_SUCCESS) {
+        // Error
+    }
+
+    ...
+    
+    ma_audio_buffer_uninit_and_free(&buffer);
+    ```
+
+If you initialize the buffer with `ma_audio_buffer_alloc_and_init()` you should uninitialize it with `ma_audio_buffer_uninit_and_free()`. In the example above,
+the memory pointed to by `pExistingData` will be copied into the buffer, which is contrary to the behavior of `ma_audio_buffer_init()`.
+
+An audio buffer has a playback cursor just like a decoder. As you read frames from the buffer, the cursor moves forward. The last parameter (`loop`) can be
+used to determine if the buffer should loop. The return value is the number of frames actually read. If this is less than the number of frames requested it
+means the end has been reached. This should never happen if the `loop` parameter is set to true. If you want to manually loop back to the start, you can do so
+with with `ma_audio_buffer_seek_to_pcm_frame(pAudioBuffer, 0)`. Below is an example for reading data from an audio buffer.
+
+    ```c
+    ma_uint64 framesRead = ma_audio_buffer_read_pcm_frames(pAudioBuffer, pFramesOut, desiredFrameCount, isLooping);
+    if (framesRead < desiredFrameCount) {
+        // If not looping, this means the end has been reached. This should never happen in looping mode with valid input.
+    }
+    ```
+
+Sometimes you may want to avoid the cost of data movement between the internal buffer and the output buffer. Instead you can use memory mapping to retrieve a
+pointer to a segment of data:
+
+    ```c
+    void* pMappedFrames;
+    ma_uint64 frameCount = frameCountToTryMapping;
+    ma_result result = ma_audio_buffer_map(pAudioBuffer, &pMappedFrames, &frameCount);
+    if (result == MA_SUCCESS) {
+        // Map was successful. The value in frameCount will be how many frames were _actually_ mapped, which may be
+        // less due to the end of the buffer being reached.
+        ma_copy_pcm_frames(pFramesOut, pMappedFrames, frameCount, pAudioBuffer->format, pAudioBuffer->channels);
+
+        // You must unmap the buffer.
+        ma_audio_buffer_unmap(pAudioBuffer, frameCount);
+    }
+    ```
+
+When you use memory mapping, the read cursor is increment by the frame count passed in to `ma_audio_buffer_unmap()`. If you decide not to process every frame
+you can pass in a value smaller than the value returned by `ma_audio_buffer_map()`. The disadvantage to using memory mapping is that it does not handle looping
+for you. You can determine if the buffer is at the end for the purpose of looping with `ma_audio_buffer_at_end()` or by inspecting the return value of
+`ma_audio_buffer_unmap()` and checking if it equals `MA_AT_END`. You should not treat `MA_AT_END` as an error when returned by `ma_audio_buffer_unmap()`.
+
+
+
+10. Ring Buffers
+================
+miniaudio supports lock free (single producer, single consumer) ring buffers which are exposed via the `ma_rb` and `ma_pcm_rb` APIs. The `ma_rb` API operates
+on bytes, whereas the `ma_pcm_rb` operates on PCM frames. They are otherwise identical as `ma_pcm_rb` is just a wrapper around `ma_rb`.
+
+Unlike most other APIs in miniaudio, ring buffers support both interleaved and deinterleaved streams. The caller can also allocate their own backing memory for
+the ring buffer to use internally for added flexibility. Otherwise the ring buffer will manage it's internal memory for you.
+
+The examples below use the PCM frame variant of the ring buffer since that's most likely the one you will want to use. To initialize a ring buffer, do
+something like the following:
+
+    ```c
+    ma_pcm_rb rb;
+    ma_result result = ma_pcm_rb_init(FORMAT, CHANNELS, BUFFER_SIZE_IN_FRAMES, NULL, NULL, &rb);
+    if (result != MA_SUCCESS) {
+        // Error
+    }
+    ```
+
+The `ma_pcm_rb_init()` function takes the sample format and channel count as parameters because it's the PCM varient of the ring buffer API. For the regular
+ring buffer that operates on bytes you would call `ma_rb_init()` which leaves these out and just takes the size of the buffer in bytes instead of frames. The
+fourth parameter is an optional pre-allocated buffer and the fifth parameter is a pointer to a `ma_allocation_callbacks` structure for custom memory allocation
+routines. Passing in `NULL` for this results in `MA_MALLOC()` and `MA_FREE()` being used.
+
+Use `ma_pcm_rb_init_ex()` if you need a deinterleaved buffer. The data for each sub-buffer is offset from each other based on the stride. To manage your
+sub-buffers you can use `ma_pcm_rb_get_subbuffer_stride()`, `ma_pcm_rb_get_subbuffer_offset()` and `ma_pcm_rb_get_subbuffer_ptr()`.
+
+Use 'ma_pcm_rb_acquire_read()` and `ma_pcm_rb_acquire_write()` to retrieve a pointer to a section of the ring buffer. You specify the number of frames you
+need, and on output it will set to what was actually acquired. If the read or write pointer is positioned such that the number of frames requested will require
+a loop, it will be clamped to the end of the buffer. Therefore, the number of frames you're given may be less than the number you requested.
+
+After calling `ma_pcm_rb_acquire_read()` or `ma_pcm_rb_acquire_write()`, you do your work on the buffer and then "commit" it with `ma_pcm_rb_commit_read()` or
+`ma_pcm_rb_commit_write()`. This is where the read/write pointers are updated. When you commit you need to pass in the buffer that was returned by the earlier
+call to `ma_pcm_rb_acquire_read()` or `ma_pcm_rb_acquire_write()` and is only used for validation. The number of frames passed to `ma_pcm_rb_commit_read()` and
+`ma_pcm_rb_commit_write()` is what's used to increment the pointers.
+
+If you want to correct for drift between the write pointer and the read pointer you can use a combination of `ma_pcm_rb_pointer_distance()`,
+`ma_pcm_rb_seek_read()` and `ma_pcm_rb_seek_write()`. Note that you can only move the pointers forward, and you should only move the read pointer forward via
+the consumer thread, and the write pointer forward by the producer thread. If there is too much space between the pointers, move the read pointer forward. If
+there is too little space between the pointers, move the write pointer forward.
+
+You can use a ring buffer at the byte level instead of the PCM frame level by using the `ma_rb` API. This is exactly the same, only you will use the `ma_rb`
+functions instead of `ma_pcm_rb` and instead of frame counts you will pass around byte counts.
+
+The maximum size of the buffer in bytes is `0x7FFFFFFF-(MA_SIMD_ALIGNMENT-1)` due to the most significant bit being used to encode a loop flag and the internally
+managed buffers always being aligned to MA_SIMD_ALIGNMENT.
+
+Note that the ring buffer is only thread safe when used by a single consumer thread and single producer thread.
+

+    +-------------+-----------------------+--------------------------------------------------------+
+
+Some backends have some nuance details you may want to be aware of.
+
+11.1. WASAPI
+------------
+- Low-latency shared mode will be disabled when using an application-defined sample rate which is different to the device's native sample rate. To work around
+  this, set `wasapi.noAutoConvertSRC` to true in the device config. This is due to IAudioClient3_InitializeSharedAudioStream() failing when the
+  `AUDCLNT_STREAMFLAGS_AUTOCONVERTPCM` flag is specified. Setting wasapi.noAutoConvertSRC will result in miniaudio's internal resampler being used instead
+  which will in turn enable the use of low-latency shared mode.
+
+11.2. PulseAudio
+----------------
+- If you experience bad glitching/noise on Arch Linux, consider this fix from the Arch wiki:
+  https://wiki.archlinux.org/index.php/PulseAudio/Troubleshooting#Glitches,_skips_or_crackling. Alternatively, consider using a different backend such as ALSA.
+
+11.3. Android
+-------------
+- To capture audio on Android, remember to add the RECORD_AUDIO permission to your manifest: `<uses-permission android:name="android.permission.RECORD_AUDIO" />`
+- With OpenSL|ES, only a single ma_context can be active at any given time. This is due to a limitation with OpenSL|ES.
+- With AAudio, only default devices are enumerated. This is due to AAudio not having an enumeration API (devices are enumerated through Java). You can however
+  perform your own device enumeration through Java and then set the ID in the ma_device_id structure (ma_device_id.aaudio) and pass it to ma_device_init().
+- The backend API will perform resampling where possible. The reason for this as opposed to using miniaudio's built-in resampler is to take advantage of any
+  potential device-specific optimizations the driver may implement.
+
+11.4. UWP
+---------
+- UWP only supports default playback and capture devices.
+- UWP requires the Microphone capability to be enabled in the application's manifest (Package.appxmanifest):
+
+    ```
+    <Package ...>
+        ...
+        <Capabilities>
+            <DeviceCapability Name="microphone" />
+        </Capabilities>
+    </Package>
+    ```
+
+11.5. Web Audio / Emscripten
+----------------------------
+- You cannot use `-std=c*` compiler flags, nor `-ansi`. This only applies to the Emscripten build.
+- The first time a context is initialized it will create a global object called "miniaudio" whose primary purpose is to act as a factory for device objects.
+- Currently the Web Audio backend uses ScriptProcessorNode's, but this may need to change later as they've been deprecated.
+- Google has implemented a policy in their browsers that prevent automatic media output without first receiving some kind of user input. The following web page
+  has additional details: https://developers.google.com/web/updates/2017/09/autoplay-policy-changes. Starting the device may fail if you try to start playback
+  without first handling some kind of user input.
+
+
+
+12. Miscellaneous Notes
+=======================
+- Automatic stream routing is enabled on a per-backend basis. Support is explicitly enabled for WASAPI and Core Audio, however other backends such as
+  PulseAudio may naturally support it, though not all have been tested.
+- The contents of the output buffer passed into the data callback will always be pre-initialized to zero unless the `noPreZeroedOutputBuffer` config variable
+  in `ma_device_config` is set to true, in which case it'll be undefined which will require you to write something to the entire buffer.
+- By default miniaudio will automatically clip samples. This only applies when the playback sample format is configured as `ma_format_f32`. If you are doing
+  clipping yourself, you can disable this overhead by setting `noClip` to true in the device config.
+- The sndio backend is currently only enabled on OpenBSD builds.
+- The audio(4) backend is supported on OpenBSD, but you may need to disable sndiod before you can use it.
+- Note that GCC and Clang requires `-msse2`, `-mavx2`, etc. for SIMD optimizations.
+- When compiling with VC6 and earlier, decoding is restricted to files less than 2GB in size. This is due to 64-bit file APIs not being available.

+Logging Levels
+==============
+A log level will automatically include the lower levels. For example, verbose logging will enable everything. The warning log level will only include warnings
+and errors, but will ignore informational and verbose logging. If you only want to handle a specific log level, implement a custom log callback (see
+ma_context_init() for details) and interrogate the `logLevel` parameter.
+
+By default the log level will be set to MA_LOG_LEVEL_ERROR, but you can change this by defining MA_LOG_LEVEL before the implementation of miniaudio.
+
+MA_LOG_LEVEL_VERBOSE
+    Mainly intended for debugging. This will enable all log levels and can be triggered from within the data callback so care must be taken when enabling this
+    in production environments.
+
+MA_LOG_LEVEL_INFO
+    Informational logging. Useful for debugging. This will also enable warning and error logs. This will never be called from within the data callback.
+
+MA_LOG_LEVEL_WARNING
+    Warnings. You should enable this in you development builds and action them when encounted. This will also enable error logs. These logs usually indicate a
+    potential problem or misconfiguration, but still allow you to keep running. This will never be called from within the data callback.
+
+MA_LOG_LEVEL_ERROR
+    Error logging. This will be fired when an operation fails and is subsequently aborted. This can be fired from within the data callback, in which case the
+    device will be stopped. You should always have this log level enabled.

+The callback for processing audio data from the device.
+
+The data callback is fired by miniaudio whenever the device needs to have more data delivered to a playback device, or when a capture device has some data
+available. This is called as soon as the backend asks for more data which means it may be called with inconsistent frame counts. You cannot assume the

+----------
+pDevice (in)
+    A pointer to the relevant device.
+
+pOutput (out)
+    A pointer to the output buffer that will receive audio data that will later be played back through the speakers. This will be non-null for a playback or
+    full-duplex device and null for a capture and loopback device.
+
+pInput (in)
+    A pointer to the buffer containing input data from a recording device. This will be non-null for a capture, full-duplex or loopback device and null for a
+    playback device.
+
+frameCount (in)
+    The number of PCM frames to process. Note that this will not necessarily be equal to what you requested when you initialized the device. The

+    not assume this will always be the same value each time the callback is fired.
+
+
+Remarks
+-------
+You cannot stop and start the device from inside the callback or else you'll get a deadlock. You must also not uninitialize the device from inside the
+callback. The following APIs cannot be called from inside the callback:
+
+    ma_device_init()
+    ma_device_init_ex()
+    ma_device_uninit()
+    ma_device_start()
+    ma_device_stop()

+Parameters
+----------
+pContext (in)
+    A pointer to the context performing the enumeration.
+
+deviceType (in)
+    The type of the device being enumerated. This will always be either `ma_device_type_playback` or `ma_device_type_capture`.
+
+pInfo (in)
+    A pointer to a `ma_device_info` containing the ID and name of the enumerated device. Note that this will not include detailed information about the device,
+    only basic information (ID and name). The reason for this is that it would otherwise require opening the backend device to probe for the information which
+    is too inefficient.
+
+pUserData (in)
+    The user data pointer passed into `ma_context_enumerate_devices()`.

+
+
+Remarks
+-------
+You must always use this to initialize the default state of the `ma_context_config` object. Not using this will result in your program breaking when miniaudio
+is updated and new members are added to `ma_context_config`. It also sets logical defaults.
+
+You can override members of the returned object by changing it's members directly.

+Initializes a context.
+
+The context is used for selecting and initializing an appropriate backend and to represent the backend at a more global level than that of an individual
+device. There is one context to many devices, and a device is created from a context. A context is required to enumerate devices.
+
+
+Parameters
+----------
+backends (in, optional)
+    A list of backends to try initializing, in priority order. Can be NULL, in which case it uses default priority order.
+
+backendCount (in, optional)
+    The number of items in `backend`. Ignored if `backend` is NULL.
+
+pConfig (in, optional)
+    The context configuration.
+
+pContext (in)
+    A pointer to the context object being initialized.
+
+
+Return Value
+------------
+MA_SUCCESS if successful; any other error code otherwise.
+
+
+Thread Safety
+-------------
+Unsafe. Do not call this function across multiple threads as some backends read and write to global state.

+The context can be configured via the `pConfig` argument. The config object is initialized with `ma_context_config_init()`. Individual configuration settings
+can then be set directly on the structure. Below are the members of the `ma_context_config` object.
+
+    logCallback
+        Callback for handling log messages from miniaudio. 
+
+    threadPriority
+        The desired priority to use for the audio thread. Allowable values include the following:
+
+        |--------------------------------------|
+        | Thread Priority                      |
+        |--------------------------------------|

+        | ma_thread_priority_default           |
+        |--------------------------------------|
+
+    pUserData
+        A pointer to application-defined data. This can be accessed from the context object directly such as `context.pUserData`.
+
+    allocationCallbacks
+        Structure containing custom allocation callbacks. Leaving this at defaults will cause it to use MA_MALLOC, MA_REALLOC and MA_FREE. These allocation
+        callbacks will be used for anything tied to the context, including devices.
+
+    alsa.useVerboseDeviceEnumeration
+        ALSA will typically enumerate many different devices which can be intrusive and not user-friendly. To combat this, miniaudio will enumerate only unique
+        card/device pairs by default. The problem with this is that you lose a bit of flexibility and control. Setting alsa.useVerboseDeviceEnumeration makes
+        it so the ALSA backend includes all devices. Defaults to false.
+
+    pulse.pApplicationName
+        PulseAudio only. The application name to use when initializing the PulseAudio context with `pa_context_new()`.
+
+    pulse.pServerName
+        PulseAudio only. The name of the server to connect to with `pa_context_connect()`.
+
+    pulse.tryAutoSpawn
+        PulseAudio only. Whether or not to try automatically starting the PulseAudio daemon. Defaults to false. If you set this to true, keep in mind that
+        miniaudio uses a trial and error method to find the most appropriate backend, and this will result in the PulseAudio daemon starting which may be
+        intrusive for the end user.

+
+    jack.pClientName
+        The name of the client to pass to `jack_client_open()`.

+    jack.tryStartServer
+        Whether or not to try auto-starting the JACK server. Defaults to false.
+
+
+It is recommended that only a single context is active at any given time because it's a bulky data structure which performs run-time linking for the
+relevant backends every time it's initialized.
+
+The location of the context cannot change throughout it's lifetime. Consider allocating the `ma_context` object with `malloc()` if this is an issue. The
+reason for this is that a pointer to the context is stored in the `ma_device` structure.
+
+
+Example 1 - Default Initialization
+----------------------------------
+The example below shows how to initialize the context using the default configuration.
+
+```c
+ma_context context;
+ma_result result = ma_context_init(NULL, 0, NULL, &context);
+if (result != MA_SUCCESS) {
+    // Error.
+}
+```
+
+
+Example 2 - Custom Configuration
+--------------------------------
+The example below shows how to initialize the context using custom backend priorities and a custom configuration. In this hypothetical example, the program
+wants to prioritize ALSA over PulseAudio on Linux. They also want to avoid using the WinMM backend on Windows because it's latency is too high. They also
+want an error to be returned if no valid backend is available which they achieve by excluding the Null backend.
+
+For the configuration, the program wants to capture any log messages so they can, for example, route it to a log file and user interface.
+
+```c
+ma_backend backends[] = {
+    ma_backend_alsa,
+    ma_backend_pulseaudio,
+    ma_backend_wasapi,
+    ma_backend_dsound
+};
+
+ma_context_config config = ma_context_config_init();
+config.logCallback = my_log_callback;
+config.pUserData   = pMyUserData;
+
+ma_context context;
+ma_result result = ma_context_init(backends, sizeof(backends)/sizeof(backends[0]), &config, &context);
+if (result != MA_SUCCESS) {
+    // Error.
+    if (result == MA_NO_BACKEND) {
+        // Couldn't find an appropriate backend.
+    }
+}
+```

+This is a lower-level enumeration function to the easier to use `ma_context_get_devices()`. Use `ma_context_enumerate_devices()` if you would rather not incur
+an internal heap allocation, or it simply suits your code better.
+
+Note that this only retrieves the ID and name/description of the device. The reason for only retrieving basic information is that it would otherwise require

+MA_API ma_device_config ma_device_config_init(ma_device_type deviceType);

+
+/*
+Initializes a device.
+
+A device represents a physical audio device. The idea is you send or receive audio data from the device to either play it back through a speaker, or capture it
+from a microphone. Whether or not you should send or receive data from the device (or both) depends on the type of device you are initializing which can be
+playback, capture, full-duplex or loopback. (Note that loopback mode is only supported on select backends.) Sending and receiving audio data to and from the
+device is done via a callback which is fired by miniaudio at periodic time intervals.
+
+The frequency at which data is delivered to and from a device depends on the size of it's period. The size of the period can be defined in terms of PCM frames
+or milliseconds, whichever is more convenient. Generally speaking, the smaller the period, the lower the latency at the expense of higher CPU usage and
+increased risk of glitching due to the more frequent and granular data deliver intervals. The size of a period will depend on your requirements, but
+miniaudio's defaults should work fine for most scenarios. If you're building a game you should leave this fairly small, whereas if you're building a simple
+media player you can make it larger. Note that the period size you request is actually just a hint - miniaudio will tell the backend what you want, but the
+backend is ultimately responsible for what it gives you. You cannot assume you will get exactly what you ask for.
+
+When delivering data to and from a device you need to make sure it's in the correct format which you can set through the device configuration. You just set the
+format that you want to use and miniaudio will perform all of the necessary conversion for you internally. When delivering data to and from the callback you
+can assume the format is the same as what you requested when you initialized the device. See Remarks for more details on miniaudio's data conversion pipeline.
+
+
+Parameters
+----------
+pContext (in, optional)
+    A pointer to the context that owns the device. This can be null, in which case it creates a default context internally.
+
+pConfig (in)
+    A pointer to the device configuration. Cannot be null. See remarks for details.
+
+pDevice (out)
+    A pointer to the device object being initialized.
+
+
+Return Value
+------------
+MA_SUCCESS if successful; any other error code otherwise.
+
+
+Thread Safety
+-------------
+Unsafe. It is not safe to call this function simultaneously for different devices because some backends depend on and mutate global state. The same applies to
+calling this at the same time as `ma_device_uninit()`.
+
+
+Callback Safety
+---------------
+Unsafe. It is not safe to call this inside any callback.
+
+
+Remarks
+-------
+Setting `pContext` to NULL will result in miniaudio creating a default context internally and is equivalent to passing in a context initialized like so:
+
+    ```c
+    ma_context_init(NULL, 0, NULL, &context);
+    ```
+
+Do not set `pContext` to NULL if you are needing to open multiple devices. You can, however, use NULL when initializing the first device, and then use
+device.pContext for the initialization of other devices.
+
+The device can be configured via the `pConfig` argument. The config object is initialized with `ma_device_config_init()`. Individual configuration settings can
+then be set directly on the structure. Below are the members of the `ma_device_config` object.
+
+    deviceType
+        Must be `ma_device_type_playback`, `ma_device_type_capture`, `ma_device_type_duplex` of `ma_device_type_loopback`.
+
+    sampleRate
+        The sample rate, in hertz. The most common sample rates are 48000 and 44100. Setting this to 0 will use the device's native sample rate.
+
+    periodSizeInFrames
+        The desired size of a period in PCM frames. If this is 0, `periodSizeInMilliseconds` will be used instead. If both are 0 the default buffer size will
+        be used depending on the selected performance profile. This value affects latency. See below for details.
+
+    periodSizeInMilliseconds
+        The desired size of a period in milliseconds. If this is 0, `periodSizeInFrames` will be used instead. If both are 0 the default buffer size will be
+        used depending on the selected performance profile. The value affects latency. See below for details.
+
+    periods
+        The number of periods making up the device's entire buffer. The total buffer size is `periodSizeInFrames` or `periodSizeInMilliseconds` multiplied by
+        this value. This is just a hint as backends will be the ones who ultimately decide how your periods will be configured.
+
+    performanceProfile
+        A hint to miniaudio as to the performance requirements of your program. Can be either `ma_performance_profile_low_latency` (default) or
+        `ma_performance_profile_conservative`. This mainly affects the size of default buffers and can usually be left at it's default value.
+
+    noPreZeroedOutputBuffer
+        When set to true, the contents of the output buffer passed into the data callback will be left undefined. When set to false (default), the contents of
+        the output buffer will be cleared the zero. You can use this to avoid the overhead of zeroing out the buffer if you can guarantee that your data
+        callback will write to every sample in the output buffer, or if you are doing your own clearing.
+
+    noClip
+        When set to true, the contents of the output buffer passed into the data callback will be clipped after returning. When set to false (default), the
+        contents of the output buffer are left alone after returning and it will be left up to the backend itself to decide whether or not the clip. This only
+        applies when the playback sample format is f32.
+
+    dataCallback
+        The callback to fire whenever data is ready to be delivered to or from the device.
+
+    stopCallback
+        The callback to fire whenever the device has stopped, either explicitly via `ma_device_stop()`, or implicitly due to things like the device being
+        disconnected.
+
+    pUserData
+        The user data pointer to use with the device. You can access this directly from the device object like `device.pUserData`.
+
+    resampling.algorithm
+        The resampling algorithm to use when miniaudio needs to perform resampling between the rate specified by `sampleRate` and the device's native rate. The
+        default value is `ma_resample_algorithm_linear`, and the quality can be configured with `resampling.linear.lpfOrder`.
+
+    resampling.linear.lpfOrder
+        The linear resampler applies a low-pass filter as part of it's procesing for anti-aliasing. This setting controls the order of the filter. The higher
+        the value, the better the quality, in general. Setting this to 0 will disable low-pass filtering altogether. The maximum value is
+        `MA_MAX_FILTER_ORDER`. The default value is `min(4, MA_MAX_FILTER_ORDER)`.
+
+    playback.pDeviceID
+        A pointer to a `ma_device_id` structure containing the ID of the playback device to initialize. Setting this NULL (default) will use the system's
+        default playback device. Retrieve the device ID from the `ma_device_info` structure, which can be retrieved using device enumeration.
+
+    playback.format
+        The sample format to use for playback. When set to `ma_format_unknown` the device's native format will be used. This can be retrieved after
+        initialization from the device object directly with `device.playback.format`.
+
+    playback.channels
+        The number of channels to use for playback. When set to 0 the device's native channel count will be used. This can be retrieved after initialization
+        from the device object directly with `device.playback.channels`.
+
+    playback.channelMap
+        The channel map to use for playback. When left empty, the device's native channel map will be used. This can be retrieved after initialization from the
+        device object direct with `device.playback.channelMap`.
+
+    playback.shareMode
+        The preferred share mode to use for playback. Can be either `ma_share_mode_shared` (default) or `ma_share_mode_exclusive`. Note that if you specify
+        exclusive mode, but it's not supported by the backend, initialization will fail. You can then fall back to shared mode if desired by changing this to
+        ma_share_mode_shared and reinitializing.
+
+    capture.pDeviceID
+        A pointer to a `ma_device_id` structure containing the ID of the capture device to initialize. Setting this NULL (default) will use the system's
+        default capture device. Retrieve the device ID from the `ma_device_info` structure, which can be retrieved using device enumeration.
+
+    capture.format
+        The sample format to use for capture. When set to `ma_format_unknown` the device's native format will be used. This can be retrieved after
+        initialization from the device object directly with `device.capture.format`.
+
+    capture.channels
+        The number of channels to use for capture. When set to 0 the device's native channel count will be used. This can be retrieved after initialization
+        from the device object directly with `device.capture.channels`.
+
+    capture.channelMap
+        The channel map to use for capture. When left empty, the device's native channel map will be used. This can be retrieved after initialization from the
+        device object direct with `device.capture.channelMap`.
+
+    capture.shareMode
+        The preferred share mode to use for capture. Can be either `ma_share_mode_shared` (default) or `ma_share_mode_exclusive`. Note that if you specify
+        exclusive mode, but it's not supported by the backend, initialization will fail. You can then fall back to shared mode if desired by changing this to
+        ma_share_mode_shared and reinitializing.
+
+    wasapi.noAutoConvertSRC
+        WASAPI only. When set to true, disables WASAPI's automatic resampling and forces the use of miniaudio's resampler. Defaults to false. 
+
+    wasapi.noDefaultQualitySRC
+        WASAPI only. Only used when `wasapi.noAutoConvertSRC` is set to false. When set to true, disables the use of `AUDCLNT_STREAMFLAGS_SRC_DEFAULT_QUALITY`.
+        You should usually leave this set to false, which is the default.
+
+    wasapi.noAutoStreamRouting
+        WASAPI only. When set to true, disables automatic stream routing on the WASAPI backend. Defaults to false.
+
+    wasapi.noHardwareOffloading
+        WASAPI only. When set to true, disables the use of WASAPI's hardware offloading feature. Defaults to false.
+
+    alsa.noMMap
+        ALSA only. When set to true, disables MMap mode. Defaults to false.
+
+    alsa.noAutoFormat
+        ALSA only. When set to true, disables ALSA's automatic format conversion by including the SND_PCM_NO_AUTO_FORMAT flag. Defaults to false.
+
+    alsa.noAutoChannels
+        ALSA only. When set to true, disables ALSA's automatic channel conversion by including the SND_PCM_NO_AUTO_CHANNELS flag. Defaults to false.
+
+    alsa.noAutoResample
+        ALSA only. When set to true, disables ALSA's automatic resampling by including the SND_PCM_NO_AUTO_RESAMPLE flag. Defaults to false.
+
+    pulse.pStreamNamePlayback
+        PulseAudio only. Sets the stream name for playback.
+
+    pulse.pStreamNameCapture
+        PulseAudio only. Sets the stream name for capture.
+
+
+Once initialized, the device's config is immutable. If you need to change the config you will need to initialize a new device.
+
+After initializing the device it will be in a stopped state. To start it, use `ma_device_start()`.
+
+If both `periodSizeInFrames` and `periodSizeInMilliseconds` are set to zero, it will default to `MA_DEFAULT_PERIOD_SIZE_IN_MILLISECONDS_LOW_LATENCY` or
+`MA_DEFAULT_PERIOD_SIZE_IN_MILLISECONDS_CONSERVATIVE`, depending on whether or not `performanceProfile` is set to `ma_performance_profile_low_latency` or
+`ma_performance_profile_conservative`.
+
+If you request exclusive mode and the backend does not support it an error will be returned. For robustness, you may want to first try initializing the device
+in exclusive mode, and then fall back to shared mode if required. Alternatively you can just request shared mode (the default if you leave it unset in the
+config) which is the most reliable option. Some backends do not have a practical way of choosing whether or not the device should be exclusive or not (ALSA,
+for example) in which case it just acts as a hint. Unless you have special requirements you should try avoiding exclusive mode as it's intrusive to the user.
+Starting with Windows 10, miniaudio will use low-latency shared mode where possible which may make exclusive mode unnecessary.
+
+When sending or receiving data to/from a device, miniaudio will internally perform a format conversion to convert between the format specified by the config
+and the format used internally by the backend. If you pass in 0 for the sample format, channel count, sample rate _and_ channel map, data transmission will run
+on an optimized pass-through fast path. You can retrieve the format, channel count and sample rate by inspecting the `playback/capture.format`,
+`playback/capture.channels` and `sampleRate` members of the device object.
+
+When compiling for UWP you must ensure you call this function on the main UI thread because the operating system may need to present the user with a message
+asking for permissions. Please refer to the official documentation for ActivateAudioInterfaceAsync() for more information.
+
+ALSA Specific: When initializing the default device, requesting shared mode will try using the "dmix" device for playback and the "dsnoop" device for capture.
+If these fail it will try falling back to the "hw" device.
+
+
+Example 1 - Simple Initialization
+---------------------------------
+This example shows how to initialize a simple playback device using a standard configuration. If you are just needing to do simple playback from the default
+playback device this is usually all you need.
+
+```c
+ma_device_config config = ma_device_config_init(ma_device_type_playback);
+config.playback.format   = ma_format_f32;
+config.playback.channels = 2;
+config.sampleRate        = 48000;
+config.dataCallback      = ma_data_callback;
+config.pMyUserData       = pMyUserData;
+
+ma_device device;
+ma_result result = ma_device_init(NULL, &config, &device);
+if (result != MA_SUCCESS) {
+    // Error
+}
+```
+
+
+Example 2 - Advanced Initialization
+-----------------------------------
+This example shows how you might do some more advanced initialization. In this hypothetical example we want to control the latency by setting the buffer size
+and period count. We also want to allow the user to be able to choose which device to output from which means we need a context so we can perform device
+enumeration.
+
+```c
+ma_context context;
+ma_result result = ma_context_init(NULL, 0, NULL, &context);
+if (result != MA_SUCCESS) {
+    // Error
+}
+
+ma_device_info* pPlaybackDeviceInfos;
+ma_uint32 playbackDeviceCount;
+result = ma_context_get_devices(&context, &pPlaybackDeviceInfos, &playbackDeviceCount, NULL, NULL);
+if (result != MA_SUCCESS) {
+    // Error
+}
+
+// ... choose a device from pPlaybackDeviceInfos ...
+
+ma_device_config config = ma_device_config_init(ma_device_type_playback);
+config.playback.pDeviceID       = pMyChosenDeviceID;    // <-- Get this from the `id` member of one of the `ma_device_info` objects returned by ma_context_get_devices().
+config.playback.format          = ma_format_f32;
+config.playback.channels        = 2;
+config.sampleRate               = 48000;
+config.dataCallback             = ma_data_callback;
+config.pUserData                = pMyUserData;
+config.periodSizeInMilliseconds = 10;
+config.periods                  = 3;
+
+ma_device device;
+result = ma_device_init(&context, &config, &device);

+
+The returned backends are determined based on compile time settings, not the platform it's currently running on. For

+        problems with some device configurations when used in conjunction with MMAP access mode. To fix this problem we need to disable
+        resampling.
+        
+        To reproduce this problem, open the "plug:dmix" device, and set the sample rate to 44100. Internally, it looks like dmix uses a
+        sample rate of 48000. The hardware parameters will get set correctly with no errors, but it looks like the 44100 -> 48000 resampling
+        doesn't work properly - but only with MMAP access mode. You will notice skipping/crackling in the audio, and it'll run at a slightly
+        faster rate.
+        
+        miniaudio has built-in support for sample rate conversion (albeit low quality at the moment), so disabling resampling should be fine
+        for us. The only problem is that it won't be taking advantage of any kind of hardware-accelerated resampling and it won't be very
+        good quality until I get a chance to improve the quality of miniaudio's software sample rate conversion.
+        
+        I don't currently know if the dmix plugin is the only one with this error. Indeed, this is the only one I've been able to reproduce
+        this error with. In the future, we may want to restrict the disabling of resampling to only known bad plugins.

+Core Audio
+
+So far, Core Audio has been the worst backend to work with due to being both unintuitive and having almost no documentation
+apart from comments in the headers (which admittedly are quite good). For my own purposes, and for anybody out there whose
+needing to figure out how this darn thing works, I'm going to outline a few things here.
+
+Since miniaudio is a fairly low-level API, one of the things it needs is control over specific devices, and it needs to be
+able to identify whether or not it can be used as playback and/or capture. The AudioObject API is the only one I've seen
+that supports this level of detail. There was some public domain sample code I stumbled across that used the AudioComponent
+and AudioUnit APIs, but I couldn't see anything that gave low-level control over device selection and capabilities (the
+distinction between playback and capture in particular). Therefore, miniaudio is using the AudioObject API.
+
+Most (all?) functions in the AudioObject API take a AudioObjectID as it's input. This is the device identifier. When
+retrieving global information, such as the device list, you use kAudioObjectSystemObject. When retrieving device-specific
+data, you pass in the ID for that device. In order to retrieve device-specific IDs you need to enumerate over each of the
+devices. This is done using the AudioObjectGetPropertyDataSize() and AudioObjectGetPropertyData() APIs which seem to be
+the central APIs for retrieving information about the system and specific devices.
+
+To use the AudioObjectGetPropertyData() API you need to use the notion of a property address. A property address is a
+structure with three variables and is used to identify which property you are getting or setting. The first is the "selector"
+which is basically the specific property that you're wanting to retrieve or set. The second is the "scope", which is
+typically set to kAudioObjectPropertyScopeGlobal, kAudioObjectPropertyScopeInput for input-specific properties and
+kAudioObjectPropertyScopeOutput for output-specific properties. The last is the "element" which is always set to
+kAudioObjectPropertyElementMaster in miniaudio's case. I don't know of any cases where this would be set to anything different.
+
+Back to the earlier issue of device retrieval, you first use the AudioObjectGetPropertyDataSize() API to retrieve the size
+of the raw data which is just a list of AudioDeviceID's. You use the kAudioObjectSystemObject AudioObjectID, and a property
+address with the kAudioHardwarePropertyDevices selector and the kAudioObjectPropertyScopeGlobal scope. Once you have the
+size, allocate a block of memory of that size and then call AudioObjectGetPropertyData(). The data is just a list of
+AudioDeviceID's so just do "dataSize/sizeof(AudioDeviceID)" to know the device count.

+        something called AudioWorklets which _forces_ you to load a _separate_ .js file at run time... nice... Hopefully ScriptProcessorNode will continue to

+        implementation. I'll be avoiding that insane AudioWorklet API like the plague...
+
+        For capture it is a bit unintuitive. We use the ScriptProccessorNode _only_ to get the raw PCM data. It is connected to an AudioContext just like the
+        playback case, however we just output silence to the AudioContext instead of passing any real data. It would make more sense to me to use the
+        MediaRecorder API, but unfortunately you need to specify a MIME time (Opus, Vorbis, etc.) for the binary blob that's returned to the client, but I've
+        been unable to figure out how to get this as raw PCM. The closest I can think is to use the MIME type for WAV files and just parse it, but I don't know
+        how well this would work. Although ScriptProccessorNode is deprecated, in practice it seems to have pretty good browser support so I'm leaving it like
+        this for now. If anyone knows how I could get raw PCM data using the MediaRecorder API please let me know!

+    Imagine the following simplified example: You have a single input speaker which is the front/left speaker which you want to convert to
+    the following output configuration:
+    
+     - front/left
+     - side/left
+     - back/left
+    
+    The front/left output is easy - it the same speaker position so it receives the full contribution of the front/left input. The amount
+    of contribution to apply to the side/left and back/left speakers, however, is a bit more complicated.
+    
+    Imagine the front/left speaker as emitting audio from two planes - the front plane and the left plane. You can think of the front/left
+    speaker emitting half of it's total volume from the front, and the other half from the left. Since part of it's volume is being emitted
+    from the left side, and the side/left and back/left channels also emit audio from the left plane, one would expect that they would
+    receive some amount of contribution from front/left speaker. The amount of contribution depends on how many planes are shared between
+    the two speakers. Note that in the examples below I've added a top/front/left speaker as an example just to show how the math works
+    across 3 spatial dimensions.
+    
+    The first thing to do is figure out how each speaker's volume is spread over each of plane:
+     - front/left:     2 planes (front and left)      = 1/2 = half it's total volume on each plane
+     - side/left:      1 plane (left only)            = 1/1 = entire volume from left plane
+     - back/left:      2 planes (back and left)       = 1/2 = half it's total volume on each plane
+     - top/front/left: 3 planes (top, front and left) = 1/3 = one third it's total volume on each plane
+    
+    The amount of volume each channel contributes to each of it's planes is what controls how much it is willing to given and take to other
+    channels on the same plane. The volume that is willing to the given by one channel is multiplied by the volume that is willing to be
+    taken by the other to produce the final contribution.

+RELEASE NOTES - VERSION 0.10.x
+==============================
+Version 0.10 includes major API changes and refactoring, mostly concerned with the data conversion system. Data conversion is performed internally to convert
+audio data between the format requested when initializing the `ma_device` object and the format of the internal device used by the backend. The same applies
+to the `ma_decoder` object. The previous design has several design flaws and missing features which necessitated a complete redesign.
+
+
+Changes to Data Conversion
+--------------------------
+The previous data conversion system used callbacks to deliver input data for conversion. This design works well in some specific situations, but in other
+situations it has some major readability and maintenance issues. The decision was made to replace this with a more iterative approach where you just pass in a
+pointer to the input data directly rather than dealing with a callback.
+
+The following are the data conversion APIs that have been removed and their replacements:
+
+  - ma_format_converter -> ma_convert_pcm_frames_format()
+  - ma_channel_router   -> ma_channel_converter
+  - ma_src              -> ma_resampler
+  - ma_pcm_converter    -> ma_data_converter
+
+The previous conversion APIs accepted a callback in their configs. There are no longer any callbacks to deal with. Instead you just pass the data into the
+`*_process_pcm_frames()` function as a pointer to a buffer.
+
+The simplest aspect of data conversion is sample format conversion. To convert between two formats, just call `ma_convert_pcm_frames_format()`. Channel
+conversion is also simple which you can do with `ma_channel_converter` via `ma_channel_converter_process_pcm_frames()`.
+
+Resampling is more complicated because the number of output frames that are processed is different to the number of input frames that are consumed. When you
+call `ma_resampler_process_pcm_frames()` you need to pass in the number of input frames available for processing and the number of output frames you want to
+output. Upon returning they will receive the number of input frames that were consumed and the number of output frames that were generated.
+
+The `ma_data_converter` API is a wrapper around format, channel and sample rate conversion and handles all of the data conversion you'll need which probably
+makes it the best option if you need to do data conversion.
+
+In addition to changes to the API design, a few other changes have been made to the data conversion pipeline:
+
+  - The sinc resampler has been removed. This was completely broken and never actually worked properly.
+  - The linear resampler now uses low-pass filtering to remove aliasing. The quality of the low-pass filter can be controlled via the resampler config with the
+    `lpfOrder` option, which has a maximum value of MA_MAX_FILTER_ORDER.
+  - Data conversion now supports s16 natively which runs through a fixed point pipeline. Previously everything needed to be converted to floating point before
+    processing, whereas now both s16 and f32 are natively supported. Other formats still require conversion to either s16 or f32 prior to processing, however
+    `ma_data_converter` will handle this for you.
+
+
+Custom Memory Allocators
+------------------------
+miniaudio has always supported macro level customization for memory allocation via MA_MALLOC, MA_REALLOC and MA_FREE, however some scenarios require more
+flexibility by allowing a user data pointer to be passed to the custom allocation routines. Support for this has been added to version 0.10 via the
+`ma_allocation_callbacks` structure. Anything making use of heap allocations has been updated to accept this new structure.
+
+The `ma_context_config` structure has been updated with a new member called `allocationCallbacks`. Leaving this set to it's defaults returned by
+`ma_context_config_init()` will cause it to use MA_MALLOC, MA_REALLOC and MA_FREE. Likewise, The `ma_decoder_config` structure has been updated in the same
+way, and leaving everything as-is after `ma_decoder_config_init()` will cause it to use the same defaults.
+
+The following APIs have been updated to take a pointer to a `ma_allocation_callbacks` object. Setting this parameter to NULL will cause it to use defaults.
+Otherwise they will use the relevant callback in the structure.
+
+  - ma_malloc()
+  - ma_realloc()
+  - ma_free()
+  - ma_aligned_malloc()
+  - ma_aligned_free()
+  - ma_rb_init() / ma_rb_init_ex()
+  - ma_pcm_rb_init() / ma_pcm_rb_init_ex()
+
+Note that you can continue to use MA_MALLOC, MA_REALLOC and MA_FREE as per normal. These will continue to be used by default if you do not specify custom
+allocation callbacks.
+
+
+Buffer and Period Configuration Changes
+---------------------------------------
+The way in which the size of the internal buffer and periods are specified in the device configuration have changed. In previous versions, the config variables
+`bufferSizeInFrames` and `bufferSizeInMilliseconds` defined the size of the entire buffer, with the size of a period being the size of this variable divided by
+the period count. This became confusing because people would expect the value of `bufferSizeInFrames` or `bufferSizeInMilliseconds` to independantly determine
+latency, when in fact it was that value divided by the period count that determined it. These variables have been removed and replaced with new ones called
+`periodSizeInFrames` and `periodSizeInMilliseconds`.
+
+These new configuration variables work in the same way as their predecessors in that if one is set to 0, the other will be used, but the main difference is
+that you now set these to you desired latency rather than the size of the entire buffer. The benefit of this is that it's much easier and less confusing to
+configure latency.
+
+The following unused APIs have been removed:
+
+    ma_get_default_buffer_size_in_milliseconds()
+    ma_get_default_buffer_size_in_frames()
+
+The following macros have been removed:
+
+    MA_BASE_BUFFER_SIZE_IN_MILLISECONDS_LOW_LATENCY
+    MA_BASE_BUFFER_SIZE_IN_MILLISECONDS_CONSERVATIVE
+
+
+Other API Changes
+-----------------
+Other less major API changes have also been made in version 0.10.
+
+`ma_device_set_stop_callback()` has been removed. If you require a stop callback, you must now set it via the device config just like the data callback.
+
+The `ma_sine_wave` API has been replaced with a more general API called `ma_waveform`. This supports generation of different types of waveforms, including
+sine, square, triangle and sawtooth. Use `ma_waveform_init()` in place of `ma_sine_wave_init()` to initialize the waveform object. This takes a configuration
+object called `ma_waveform_config` which defines the properties of the waveform. Use `ma_waveform_config_init()` to initialize a `ma_waveform_config` object.
+Use `ma_waveform_read_pcm_frames()` in place of `ma_sine_wave_read_f32()` and `ma_sine_wave_read_f32_ex()`.
+
+`ma_convert_frames()` and `ma_convert_frames_ex()` have been changed. Both of these functions now take a new parameter called `frameCountOut` which specifies
+the size of the output buffer in PCM frames. This has been added for safety. In addition to this, the parameters for `ma_convert_frames_ex()` have changed to
+take a pointer to a `ma_data_converter_config` object to specify the input and output formats to convert between. This was done to make it more flexible, to
+prevent the parameter list getting too long, and to prevent API breakage whenever a new conversion property is added.
+
+`ma_calculate_frame_count_after_src()` has been renamed to `ma_calculate_frame_count_after_resampling()` for consistency with the new `ma_resampler` API.
+
+
+Filters
+-------
+The following filters have been added:
+
+    |-------------|-------------------------------------------------------------------|
+    | API         | Description                                                       |
+    |-------------|-------------------------------------------------------------------|
+    | ma_biquad   | Biquad filter (transposed direct form 2)                          |
+    | ma_lpf1     | First order low-pass filter                                       |
+    | ma_lpf2     | Second order low-pass filter                                      |
+    | ma_lpf      | High order low-pass filter (Butterworth)                          |
+    | ma_hpf1     | First order high-pass filter                                      |
+    | ma_hpf2     | Second order high-pass filter                                     |
+    | ma_hpf      | High order high-pass filter (Butterworth)                         |
+    | ma_bpf2     | Second order band-pass filter                                     |
+    | ma_bpf      | High order band-pass filter                                       |
+    | ma_peak2    | Second order peaking filter                                       |
+    | ma_notch2   | Second order notching filter                                      |
+    | ma_loshelf2 | Second order low shelf filter                                     |
+    | ma_hishelf2 | Second order high shelf filter                                    |
+    |-------------|-------------------------------------------------------------------|
+
+These filters all support 32-bit floating point and 16-bit signed integer formats natively. Other formats need to be converted beforehand.
+
+
+Sine, Square, Triangle and Sawtooth Waveforms
+---------------------------------------------
+Previously miniaudio supported only sine wave generation. This has now been generalized to support sine, square, triangle and sawtooth waveforms. The old
+`ma_sine_wave` API has been removed and replaced with the `ma_waveform` API. Use `ma_waveform_config_init()` to initialize a config object, and then pass it
+into `ma_waveform_init()`. Then use `ma_waveform_read_pcm_frames()` to read PCM data.
+
+
+Noise Generation
+----------------
+A noise generation API has been added. This is used via the `ma_noise` API. Currently white, pink and Brownian noise is supported. The `ma_noise` API is
+similar to the waveform API. Use `ma_noise_config_init()` to initialize a config object, and then pass it into `ma_noise_init()` to initialize a `ma_noise`
+object. Then use `ma_noise_read_pcm_frames()` to read PCM data.
+
+
+Miscellaneous Changes
+---------------------
+The MA_NO_STDIO option has been removed. This would disable file I/O APIs, however this has proven to be too hard to maintain for it's perceived value and was
+therefore removed.
+
+Internal functions have all been made static where possible. If you get warnings about unused functions, please submit a bug report.
+
+The `ma_device` structure is no longer defined as being aligned to MA_SIMD_ALIGNMENT. This resulted in a possible crash when allocating a `ma_device` object on
+the heap, but not aligning it to MA_SIMD_ALIGNMENT. This crash would happen due to the compiler seeing the alignment specified on the structure and assuming it
+was always aligned as such and thinking it was safe to emit alignment-dependant SIMD instructions. Since miniaudio's philosophy is for things to just work,
+this has been removed from all structures.
+
+Results codes have been overhauled. Unnecessary result codes have been removed, and some have been renumbered for organisation purposes. If you are are binding
+maintainer you will need to update your result codes. Support has also been added for retrieving a human readable description of a given result code via the
+`ma_result_description()` API.
+
+ALSA: The automatic format conversion, channel conversion and resampling performed by ALSA is now disabled by default as they were causing some compatibility
+issues with certain devices and configurations. These can be individually enabled via the device config:
+
+    ```c
+    deviceConfig.alsa.noAutoFormat   = MA_TRUE;
+    deviceConfig.alsa.noAutoChannels = MA_TRUE;
+    deviceConfig.alsa.noAutoResample = MA_TRUE;
+    ```

+RELEASE NOTES - VERSION 0.9.x
+=============================
+Version 0.9 includes major API changes, centered mostly around full-duplex and the rebrand to "miniaudio". Before I go into detail about the major changes I
+would like to apologize. I know it's annoying dealing with breaking API changes, but I think it's best to get these changes out of the way now while the
+library is still relatively young and unknown.
+
+There's been a lot of refactoring with this release so there's a good chance a few bugs have been introduced. I apologize in advance for this. You may want to
+hold off on upgrading for the short term if you're worried. If mini_al v0.8.14 works for you, and you don't need full-duplex support, you can avoid upgrading
+(though you won't be getting future bug fixes).
+
+
+Rebranding to "miniaudio"
+-------------------------
+The decision was made to rename mini_al to miniaudio. Don't worry, it's the same project. The reason for this is simple:
+
+1) Having the word "audio" in the title makes it immediately clear that the library is related to audio; and
+2) I don't like the look of the underscore.
+
+This rebrand has necessitated a change in namespace from "mal" to "ma". I know this is annoying, and I apologize, but it's better to get this out of the road
+now rather than later. Also, since there are necessary API changes for full-duplex support I think it's better to just get the namespace change over and done
+with at the same time as the full-duplex changes. I'm hoping this will be the last of the major API changes. Fingers crossed!
+
+The implementation define is now "#define MINIAUDIO_IMPLEMENTATION". You can also use "#define MA_IMPLEMENTATION" if that's your preference.
+
+
+Full-Duplex Support
+-------------------
+The major feature added to version 0.9 is full-duplex. This has necessitated a few API changes.
+
+1) The data callback has now changed. Previously there was one type of callback for playback and another for capture. I wanted to avoid a third callback just
+   for full-duplex so the decision was made to break this API and unify the callbacks. Now, there is just one callback which is the same for all three modes
+   (playback, capture, duplex). The new callback looks like the following:
+
+       void data_callback(ma_device* pDevice, void* pOutput, const void* pInput, ma_uint32 frameCount);
+
+   This callback allows you to move data straight out of the input buffer and into the output buffer in full-duplex mode. In playback-only mode, pInput will be
+   null. Likewise, pOutput will be null in capture-only mode. The sample count is no longer returned from the callback since it's not necessary for miniaudio
+   anymore.
+
+2) The device config needed to change in order to support full-duplex. Full-duplex requires the ability to allow the client to choose a different PCM format
+   for the playback and capture sides. The old ma_device_config object simply did not allow this and needed to change. With these changes you now specify the
+   device ID, format, channels, channel map and share mode on a per-playback and per-capture basis (see example below). The sample rate must be the same for
+   playback and capture.
+
+   Since the device config API has changed I have also decided to take the opportunity to simplify device initialization. Now, the device ID, device type and
+   callback user data are set in the config. ma_device_init() is now simplified down to taking just the context, device config and a pointer to the device
+   object being initialized. The rationale for this change is that it just makes more sense to me that these are set as part of the config like everything
+   else.
+
+   Example device initialization:
+
+       ma_device_config config = ma_device_config_init(ma_device_type_duplex);   // Or ma_device_type_playback or ma_device_type_capture.
+       config.playback.pDeviceID = &myPlaybackDeviceID; // Or NULL for the default playback device.
+       config.playback.format    = ma_format_f32;
+       config.playback.channels  = 2;
+       config.capture.pDeviceID  = &myCaptureDeviceID;  // Or NULL for the default capture device.
+       config.capture.format     = ma_format_s16;
+       config.capture.channels   = 1;
+       config.sampleRate         = 44100;
+       config.dataCallback       = data_callback;
+       config.pUserData          = &myUserData;
+
+       result = ma_device_init(&myContext, &config, &device);
+       if (result != MA_SUCCESS) {
+           ... handle error ...
+       }
+
+   Note that the "onDataCallback" member of ma_device_config has been renamed to "dataCallback". Also, "onStopCallback" has been renamed to "stopCallback".
+
+This is the first pass for full-duplex and there is a known bug. You will hear crackling on the following backends when sample rate conversion is required for
+the playback device:
+  - Core Audio
+  - JACK
+  - AAudio
+  - OpenSL
+  - WebAudio
+
+In addition to the above, not all platforms have been absolutely thoroughly tested simply because I lack the hardware for such thorough testing. If you
+experience a bug, an issue report on GitHub or an email would be greatly appreciated (and a sample program that reproduces the issue if possible).
+
+
+Other API Changes
+-----------------
+In addition to the above, the following API changes have been made:
+
+- The log callback is no longer passed to ma_context_config_init(). Instead you need to set it manually after initialization.
+- The onLogCallback member of ma_context_config has been renamed to "logCallback".
+- The log callback now takes a logLevel parameter. The new callback looks like: void log_callback(ma_context* pContext, ma_device* pDevice, ma_uint32 logLevel, const char* message)
+  - You can use ma_log_level_to_string() to convert the logLevel to human readable text if you want to log it.
+- Some APIs have been renamed:
+  - mal_decoder_read()          -> ma_decoder_read_pcm_frames()
+  - mal_decoder_seek_to_frame() -> ma_decoder_seek_to_pcm_frame()
+  - mal_sine_wave_read()        -> ma_sine_wave_read_f32()
+  - mal_sine_wave_read_ex()     -> ma_sine_wave_read_f32_ex()
+- Some APIs have been removed:
+  - mal_device_get_buffer_size_in_bytes()
+  - mal_device_set_recv_callback()
+  - mal_device_set_send_callback()
+  - mal_src_set_input_sample_rate()
+  - mal_src_set_output_sample_rate()
+- Error codes have been rearranged. If you're a binding maintainer you will need to update.
+- The ma_backend enums have been rearranged to priority order. The rationale for this is to simplify automatic backend selection and to make it easier to see
+  the priority. If you're a binding maintainer you will need to update.
+- ma_dsp has been renamed to ma_pcm_converter. The rationale for this change is that I'm expecting "ma_dsp" to conflict with some future planned high-level
+  APIs.
+- For functions that take a pointer/count combo, such as ma_decoder_read_pcm_frames(), the parameter order has changed so that the pointer comes before the
+  count. The rationale for this is to keep it consistent with things like memcpy().
+
+
+Miscellaneous Changes
+---------------------
+The following miscellaneous changes have also been made.
+
+- The AAudio backend has been added for Android 8 and above. This is Android's new "High-Performance Audio" API. (For the record, this is one of the nicest
+  audio APIs out there, just behind the BSD audio APIs).
+- The WebAudio backend has been added. This is based on ScriptProcessorNode. This removes the need for SDL.
+- The SDL and OpenAL backends have been removed. These were originally implemented to add support for platforms for which miniaudio was not explicitly
+  supported. These are no longer needed and have therefore been removed.
+- Device initialization now fails if the requested share mode is not supported. If you ask for exclusive mode, you either get an exclusive mode device, or an
+  error. The rationale for this change is to give the client more control over how to handle cases when the desired shared mode is unavailable.
+- A lock-free ring buffer API has been added. There are two varients of this. "ma_rb" operates on bytes, whereas "ma_pcm_rb" operates on PCM frames.
+- The library is now licensed as a choice of Public Domain (Unlicense) _or_ MIT-0 (No Attribution) which is the same as MIT, but removes the attribution
+  requirement. The rationale for this is to support countries that don't recognize public domain.

+  - Mark ma_device_sink_info_callback() as static.
+  - Fix compilation errors with MA_NO_DECODING and MA_NO_ENCODING.
+  - Fix compilation errors with MA_NO_DEVICE_IO
+
+v0.10.9 - 2020-06-24
+  - Amalgamation of dr_wav, dr_flac and dr_mp3. With this change, including the header section of these libraries before the implementation of miniaudio is no
+    longer required. Decoding of WAV, FLAC and MP3 should be supported seamlessly without any additional libraries. Decoders can be excluded from the build
+    with the following options:

+    - MA_NO_FLAC
+    - MA_NO_MP3
+    If you get errors about multiple definitions you need to either enable the options above, move the implementation of dr_wav, dr_flac and/or dr_mp3 to before

+v0.10.8 - 2020-06-22
+  - Remove dependency on ma_context from mutexes.
+  - Change ma_data_source_read_pcm_frames() to return a result code and output the frames read as an output parameter.
+  - Change ma_data_source_seek_pcm_frames() to return a result code and output the frames seeked as an output parameter.
+  - Change ma_audio_buffer_unmap() to return MA_AT_END when the end has been reached. This should be considered successful.
+  - Change playback.pDeviceID and capture.pDeviceID to constant pointers in ma_device_config.
+  - Add support for initializing decoders from a virtual file system object. This is achieved via the ma_vfs API and allows the application to customize file
+    IO for the loading and reading of raw audio data. Passing in NULL for the VFS will use defaults. New APIs:
+    - ma_decoder_init_vfs()
+    - ma_decoder_init_vfs_wav()
+    - ma_decoder_init_vfs_flac()
+    - ma_decoder_init_vfs_mp3()
+    - ma_decoder_init_vfs_vorbis()
+    - ma_decoder_init_vfs_w()
+    - ma_decoder_init_vfs_wav_w()
+    - ma_decoder_init_vfs_flac_w()
+    - ma_decoder_init_vfs_mp3_w()
+    - ma_decoder_init_vfs_vorbis_w()
+  - Add support for memory mapping to ma_data_source.
+    - ma_data_source_map()
+    - ma_data_source_unmap()
+  - Add ma_offset_pcm_frames_ptr() and ma_offset_pcm_frames_const_ptr() which can be used for offsetting a pointer by a specified number of PCM frames.

+
+v0.10.3 - 2020-04-07
+  - Bring up to date with breaking changes to dr_mp3.

+  - Decorate some APIs with MA_API which were missed in the previous version.
+  - Fix a bug in ma_linear_resampler_set_rate() and ma_linear_resampler_set_rate_ratio().

+  - Fix warnings on macOS.
+
+v0.10.0 - 2020-03-07
+  - API CHANGE: Refactor data conversion APIs
+    - ma_format_converter has been removed. Use ma_convert_pcm_frames_format() instead.
+    - ma_channel_router has been replaced with ma_channel_converter.
+    - ma_src has been replaced with ma_resampler
+    - ma_pcm_converter has been replaced with ma_data_converter
+  - API CHANGE: Add support for custom memory allocation callbacks. The following APIs have been updated to take an extra parameter for the allocation
+    callbacks:
+    - ma_malloc()
+    - ma_realloc()
+    - ma_free()
+    - ma_aligned_malloc()
+    - ma_aligned_free()
+    - ma_rb_init() / ma_rb_init_ex()
+    - ma_pcm_rb_init() / ma_pcm_rb_init_ex()
+  - API CHANGE: Simplify latency specification in device configurations. The bufferSizeInFrames and bufferSizeInMilliseconds parameters have been replaced with
+    periodSizeInFrames and periodSizeInMilliseconds respectively. The previous variables defined the size of the entire buffer, whereas the new ones define the
+    size of a period. The following APIs have been removed since they are no longer relevant:
+    - ma_get_default_buffer_size_in_milliseconds()
+    - ma_get_default_buffer_size_in_frames()
+  - API CHANGE: ma_device_set_stop_callback() has been removed. If you require a stop callback, you must now set it via the device config just like the data
+    callback.
+  - API CHANGE: The ma_sine_wave API has been replaced with ma_waveform. The following APIs have been removed:
+    - ma_sine_wave_init()
+    - ma_sine_wave_read_f32()
+    - ma_sine_wave_read_f32_ex()
+  - API CHANGE: ma_convert_frames() has been updated to take an extra parameter which is the size of the output buffer in PCM frames. Parameters have also been
+    reordered.
+  - API CHANGE: ma_convert_frames_ex() has been changed to take a pointer to a ma_data_converter_config object to specify the input and output formats to
+    convert between.
+  - API CHANGE: ma_calculate_frame_count_after_src() has been renamed to ma_calculate_frame_count_after_resampling().
+  - Add support for the following filters:
+    - Biquad (ma_biquad)
+    - First order low-pass (ma_lpf1)
+    - Second order low-pass (ma_lpf2)
+    - Low-pass with configurable order (ma_lpf)

+    - Sawtooth
+  - Add noise generation API (ma_noise) with support for the following:
+    - White
+    - Pink

+  - More meaningful result codes are now returned when a file fails to open.
+  - Internal functions have all been made static where possible.
+  - Fix potential crash when ma_device object's are not aligned to MA_SIMD_ALIGNMENT.
+  - Fix a bug in ma_decoder_get_length_in_pcm_frames() where it was returning the length based on the internal sample rate rather than the output sample rate.
+  - Fix bugs in some backends where the device is not drained properly in ma_device_stop().
+  - Improvements to documentation.
+
+v0.9.10 - 2020-01-15

+
+v0.9.9 - 2020-01-09
+  - Fix compilation errors with MinGW.
+  - Fix compilation errors when compiling on Apple platforms.
+  - WASAPI: Add support for disabling hardware offloading.
+  - WASAPI: Add support for disabling automatic stream routing.

+
+v0.9.8 - 2019-10-07
+  - WASAPI: Fix a potential deadlock when starting a full-duplex device.
+  - WASAPI: Enable automatic resampling by default. Disable with config.wasapi.noAutoConvertSRC.
+  - Core Audio: Fix bugs with automatic stream routing.
+  - Add support for controlling whether or not the content of the output buffer passed in to the data callback is pre-initialized
+    to zero. By default it will be initialized to zero, but this can be changed by setting noPreZeroedOutputBuffer in the device
+    config. Setting noPreZeroedOutputBuffer to true will leave the contents undefined.
+  - Add support for clipping samples after the data callback has returned. This only applies when the playback sample format is
+    configured as ma_format_f32. If you are doing clipping yourself, you can disable this overhead by setting noClip to true in
+    the device config.
+  - Add support for master volume control for devices.
+    - Use ma_device_set_master_volume() to set the volume to a factor between 0 and 1, where 0 is silence and 1 is full volume.
+    - Use ma_device_set_master_gain_db() to set the volume in decibels where 0 is full volume and < 0 reduces the volume.
+  - Fix warnings emitted by GCC when `__inline__` is undefined or defined as nothing.
+
+v0.9.7 - 2019-08-28
+  - Add support for loopback mode (WASAPI only).
+    - To use this, set the device type to ma_device_type_loopback, and then fill out the capture section of the device config.
+    - If you need to capture from a specific output device, set the capture device ID to that of a playback device.
+  - Fix a crash when an error is posted in ma_device_init().
+  - Fix a compilation error when compiling for ARM architectures.
+  - Fix a bug with the audio(4) backend where the device is incorrectly being opened in non-blocking mode.

+
+v0.9.6 - 2019-08-04
+  - Add support for loading decoders using a wchar_t string for file paths.
+  - Don't trigger an assert when ma_device_start() is called on a device that is already started. This will now log a warning
+    and return MA_INVALID_OPERATION. The same applies for ma_device_stop().
+  - Try fixing an issue with PulseAudio taking a long time to start playback.
+  - Fix a bug in ma_convert_frames() and ma_convert_frames_ex().
+  - Fix memory leaks in the WASAPI backend.
+  - Fix a compilation error with Visual Studio 2010.
+
+v0.9.5 - 2019-05-21

+  - Fix a bug with capture on the OpenSL|ES backend.
+  - Fix a bug with the ALSA backend where a device would not restart after being stopped.
+
+v0.9.4 - 2019-05-06
+  - Add support for C89. With this change, miniaudio should compile clean with GCC/Clang with "-std=c89 -ansi -pedantic" and
+    Microsoft compilers back to VC6. Other compilers should also work, but have not been tested.
+
+v0.9.3 - 2019-04-19
+  - Fix compiler errors on GCC when compiling with -std=c99.
+
+v0.9.2 - 2019-04-08
+  - Add support for per-context user data.
+  - Fix a potential bug with context configs.
+  - Fix some bugs with PulseAudio.
+
+v0.9.1 - 2019-03-17
+  - Fix a bug where the output buffer is not getting zeroed out before calling the data callback. This happens when
+    the device is running in passthrough mode (not doing any data conversion).
+  - Fix an issue where the data callback is getting called too frequently on the WASAPI and DirectSound backends.
+  - Fix error on the UWP build.
+  - Fix a build error on Apple platforms.
+
+v0.9 - 2019-03-06
+  - Rebranded to "miniaudio". All namespaces have been renamed from "mal" to "ma".
+  - API CHANGE: ma_device_init() and ma_device_config_init() have changed significantly:
+    - The device type, device ID and user data pointer have moved from ma_device_init() to the config.
+    - All variations of ma_device_config_init_*() have been removed in favor of just ma_device_config_init().
+    - ma_device_config_init() now takes only one parameter which is the device type. All other properties need
+      to be set on the returned object directly.
+    - The onDataCallback and onStopCallback members of ma_device_config have been renamed to "dataCallback"
+      and "stopCallback".
+    - The ID of the physical device is now split into two: one for the playback device and the other for the
+      capture device. This is required for full-duplex. These are named "pPlaybackDeviceID" and "pCaptureDeviceID".
+  - API CHANGE: The data callback has changed. It now uses a unified callback for all device types rather than
+    being separate for each. It now takes two pointers - one containing input data and the other output data. This
+    design in required for full-duplex. The return value is now void instead of the number of frames written. The
+    new callback looks like the following:
+        void data_callback(ma_device* pDevice, void* pOutput, const void* pInput, ma_uint32 frameCount);
+  - API CHANGE: Remove the log callback parameter from ma_context_config_init(). With this change,
+    ma_context_config_init() now takes no parameters and the log callback is set via the structure directly. The
+    new policy for config initialization is that only mandatory settings are passed in to *_config_init(). The
+    "onLog" member of ma_context_config has been renamed to "logCallback".
+  - API CHANGE: Remove ma_device_get_buffer_size_in_bytes().
+  - API CHANGE: Rename decoding APIs to "pcm_frames" convention.
+    - mal_decoder_read()          -> ma_decoder_read_pcm_frames()
+    - mal_decoder_seek_to_frame() -> ma_decoder_seek_to_pcm_frame()
+  - API CHANGE: Rename sine wave reading APIs to f32 convention.
+    - mal_sine_wave_read()    -> ma_sine_wave_read_f32()
+    - mal_sine_wave_read_ex() -> ma_sine_wave_read_f32_ex()
+  - API CHANGE: Remove some deprecated APIs
+    - mal_device_set_recv_callback()
+    - mal_device_set_send_callback()
+    - mal_src_set_input_sample_rate()
+    - mal_src_set_output_sample_rate()
+  - API CHANGE: Add log level to the log callback. New signature:
+    - void on_log(ma_context* pContext, ma_device* pDevice, ma_uint32 logLevel, const char* message)
+  - API CHANGE: Changes to result codes. Constants have changed and unused codes have been removed. If you're
+    a binding mainainer you will need to update your result code constants.
+  - API CHANGE: Change the order of the ma_backend enums to priority order. If you are a binding maintainer, you
+    will need to update.
+  - API CHANGE: Rename mal_dsp to ma_pcm_converter. All functions have been renamed from mal_dsp_*() to
+    ma_pcm_converter_*(). All structures have been renamed from mal_dsp* to ma_pcm_converter*.
+  - API CHANGE: Reorder parameters of ma_decoder_read_pcm_frames() to be consistent with the new parameter order scheme.
+  - The resampling algorithm has been changed from sinc to linear. The rationale for this is that the sinc implementation
+    is too inefficient right now. This will hopefully be improved at a later date.
+  - Device initialization will no longer fall back to shared mode if exclusive mode is requested but is unusable.
+    With this change, if you request an device in exclusive mode, but exclusive mode is not supported, it will not
+    automatically fall back to shared mode. The client will need to reinitialize the device in shared mode if that's
+    what they want.
+  - Add ring buffer API. This is ma_rb and ma_pcm_rb, the difference being that ma_rb operates on bytes and
+    ma_pcm_rb operates on PCM frames.
+  - Add Web Audio backend. This is used when compiling with Emscripten. The SDL backend, which was previously
+    used for web support, will be removed in a future version.
+  - Add AAudio backend (Android Audio). This is the new priority backend for Android. Support for AAudio starts
+    with Android 8. OpenSL|ES is used as a fallback for older versions of Android.
+  - Remove OpenAL and SDL backends.
+  - Fix a possible deadlock when rapidly stopping the device after it has started.
+  - Update documentation.
+  - Change licensing to a choice of public domain _or_ MIT-0 (No Attribution).
+
+v0.8.14 - 2018-12-16
+  - Core Audio: Fix a bug where the device state is not set correctly after stopping.
+  - Add support for custom weights to the channel router.
+  - Update decoders to use updated APIs in dr_flac, dr_mp3 and dr_wav.
+
+v0.8.13 - 2018-12-04
+  - Core Audio: Fix a bug with channel mapping.
+  - Fix a bug with channel routing where the back/left and back/right channels have the wrong weight.
+
+v0.8.12 - 2018-11-27
+  - Drop support for SDL 1.2. The Emscripten build now requires "-s USE_SDL=2".
+  - Fix a linking error with ALSA.
+  - Fix a bug on iOS where the device name is not set correctly.
+
+v0.8.11 - 2018-11-21
+  - iOS bug fixes.
+  - Minor tweaks to PulseAudio.
+
+v0.8.10 - 2018-10-21
+  - Core Audio: Fix a hang when uninitializing a device.

+
+v0.8.8 - 2018-09-14
+  - Fix Linux build with the ALSA backend.
+  - Minor documentation fix.
+
+v0.8.7 - 2018-09-12
+  - Fix a bug with UWP detection.
+
+v0.8.6 - 2018-08-26
+  - Automatically switch the internal device when the default device is unplugged. Note that this is still in the
+    early stages and not all backends handle this the same way. As of this version, this will not detect a default
+    device switch when changed from the operating system's audio preferences (unless the backend itself handles
+    this automatically). This is not supported in exclusive mode.
+  - WASAPI and Core Audio: Add support for stream routing. When the application is using a default device and the
+    user switches the default device via the operating system's audio preferences, miniaudio will automatically switch
+    the internal device to the new default. This is not supported in exclusive mode.
+  - WASAPI: Add support for hardware offloading via IAudioClient2. Only supported on Windows 8 and newer.
+  - WASAPI: Add support for low-latency shared mode via IAudioClient3. Only supported on Windows 10 and newer.
+  - Add support for compiling the UWP build as C.
+  - mal_device_set_recv_callback() and mal_device_set_send_callback() have been deprecated. You must now set this
+    when the device is initialized with mal_device_init*(). These will be removed in version 0.9.0.
+
+v0.8.5 - 2018-08-12
+  - Add support for specifying the size of a device's buffer in milliseconds. You can still set the buffer size in
+    frames if that suits you. When bufferSizeInFrames is 0, bufferSizeInMilliseconds will be used. If both are non-0
+    then bufferSizeInFrames will take priority. If both are set to 0 the default buffer size is used.
+  - Add support for the audio(4) backend to OpenBSD.
+  - Fix a bug with the ALSA backend that was causing problems on Raspberry Pi. This significantly improves the
+    Raspberry Pi experience.
+  - Fix a bug where an incorrect number of samples is returned from sinc resampling.
+  - Add support for setting the value to be passed to internal calls to CoInitializeEx().
+  - WASAPI and WinMM: Stop the device when it is unplugged.
+
+v0.8.4 - 2018-08-06
+  - Add sndio backend for OpenBSD.
+  - Add audio(4) backend for NetBSD.
+  - Drop support for the OSS backend on everything except FreeBSD and DragonFly BSD.
+  - Formats are now native-endian (were previously little-endian).
+  - Mark some APIs as deprecated:
+    - mal_src_set_input_sample_rate() and mal_src_set_output_sample_rate() are replaced with mal_src_set_sample_rate().
+    - mal_dsp_set_input_sample_rate() and mal_dsp_set_output_sample_rate() are replaced with mal_dsp_set_sample_rate().
+  - Fix a bug when capturing using the WASAPI backend.
+  - Fix some aliasing issues with resampling, specifically when increasing the sample rate.
+  - Fix warnings.
+
+v0.8.3 - 2018-07-15
+  - Fix a crackling bug when resampling in capture mode.
+  - Core Audio: Fix a bug where capture does not work.
+  - ALSA: Fix a bug where the worker thread can get stuck in an infinite loop.
+  - PulseAudio: Fix a bug where mal_context_init() succeeds when PulseAudio is unusable.
+  - JACK: Fix a bug where mal_context_init() succeeds when JACK is unusable.
+
+v0.8.2 - 2018-07-07
+  - Fix a bug on macOS with Core Audio where the internal callback is not called.
+
+v0.8.1 - 2018-07-06
+  - Fix compilation errors and warnings.
+
+v0.8 - 2018-07-05
+  - Changed MAL_IMPLEMENTATION to MINI_AL_IMPLEMENTATION for consistency with other libraries. The old
+    way is still supported for now, but you should update as it may be removed in the future.
+  - API CHANGE: Replace device enumeration APIs. mal_enumerate_devices() has been replaced with
+    mal_context_get_devices(). An additional low-level device enumration API has been introduced called
+    mal_context_enumerate_devices() which uses a callback to report devices.
+  - API CHANGE: Rename mal_get_sample_size_in_bytes() to mal_get_bytes_per_sample() and add
+    mal_get_bytes_per_frame().
+  - API CHANGE: Replace mal_device_config.preferExclusiveMode with mal_device_config.shareMode.
+    - This new config can be set to mal_share_mode_shared (default) or mal_share_mode_exclusive.
+  - API CHANGE: Remove excludeNullDevice from mal_context_config.alsa.
+  - API CHANGE: Rename MAL_MAX_SAMPLE_SIZE_IN_BYTES to MAL_MAX_PCM_SAMPLE_SIZE_IN_BYTES.
+  - API CHANGE: Change the default channel mapping to the standard Microsoft mapping.
+  - API CHANGE: Remove backend-specific result codes.
+  - API CHANGE: Changes to the format conversion APIs (mal_pcm_f32_to_s16(), etc.)
+  - Add support for Core Audio (Apple).
+  - Add support for PulseAudio.
+    - This is the highest priority backend on Linux (higher priority than ALSA) since it is commonly
+      installed by default on many of the popular distros and offer's more seamless integration on
+      platforms where PulseAudio is used. In addition, if PulseAudio is installed and running (which
+      is extremely common), it's better to just use PulseAudio directly rather than going through the
+      "pulse" ALSA plugin (which is what the "default" ALSA device is likely set to).
+  - Add support for JACK.
+  - Remove dependency on asound.h for the ALSA backend. This means the ALSA development packages are no
+    longer required to build miniaudio.
+  - Remove dependency on dsound.h for the DirectSound backend. This fixes build issues with some
+    distributions of MinGW.
+  - Remove dependency on audioclient.h for the WASAPI backend. This fixes build issues with some
+    distributions of MinGW.
+  - Add support for dithering to format conversion.
+  - Add support for configuring the priority of the worker thread.
+  - Add a sine wave generator.
+  - Improve efficiency of sample rate conversion.
+  - Introduce the notion of standard channel maps. Use mal_get_standard_channel_map().
+  - Introduce the notion of default device configurations. A default config uses the same configuration
+    as the backend's internal device, and as such results in a pass-through data transmission pipeline.
+  - Add support for passing in NULL for the device config in mal_device_init(), which uses a default
+    config. This requires manually calling mal_device_set_send/recv_callback().
+  - Add support for decoding from raw PCM data (mal_decoder_init_raw(), etc.)
+  - Make mal_device_init_ex() more robust.
+  - Make some APIs more const-correct.
+  - Fix errors with SDL detection on Apple platforms.
+  - Fix errors with OpenAL detection.
+  - Fix some memory leaks.
+  - Fix a bug with opening decoders from memory.
+  - Early work on SSE2, AVX2 and NEON optimizations.
+  - Miscellaneous bug fixes.
+  - Documentation updates.
+
+v0.7 - 2018-02-25
+  - API CHANGE: Change mal_src_read_frames() and mal_dsp_read_frames() to use 64-bit sample counts.
+  - Add decoder APIs for loading WAV, FLAC, Vorbis and MP3 files.
+  - Allow opening of devices without a context.
+    - In this case the context is created and managed internally by the device.
+  - Change the default channel mapping to the same as that used by FLAC.
+  - Fix build errors with macOS.
+
+v0.6c - 2018-02-12
+  - Fix build errors with BSD/OSS.
+
+v0.6b - 2018-02-03
+  - Fix some warnings when compiling with Visual C++.
+
+v0.6a - 2018-01-26
+  - Fix errors with channel mixing when increasing the channel count.
+  - Improvements to the build system for the OpenAL backend.
+  - Documentation fixes.
+
+v0.6 - 2017-12-08
+  - API CHANGE: Expose and improve mutex APIs. If you were using the mutex APIs before this version you'll
+    need to update.
+  - API CHANGE: SRC and DSP callbacks now take a pointer to a mal_src and mal_dsp object respectively.
+  - API CHANGE: Improvements to event and thread APIs. These changes make these APIs more consistent.
+  - Add support for SDL and Emscripten.
+  - Simplify the build system further for when development packages for various backends are not installed.
+    With this change, when the compiler supports __has_include, backends without the relevant development
+    packages installed will be ignored. This fixes the build for old versions of MinGW.
+  - Fixes to the Android build.
+  - Add mal_convert_frames(). This is a high-level helper API for performing a one-time, bulk conversion of
+    audio data to a different format.
+  - Improvements to f32 -> u8/s16/s24/s32 conversion routines.
+  - Fix a bug where the wrong value is returned from mal_device_start() for the OpenSL backend.
+  - Fixes and improvements for Raspberry Pi.
+  - Warning fixes.
+
+v0.5 - 2017-11-11
+  - API CHANGE: The mal_context_init() function now takes a pointer to a mal_context_config object for
+    configuring the context. The works in the same kind of way as the device config. The rationale for this
+    change is to give applications better control over context-level properties, add support for backend-
+    specific configurations, and support extensibility without breaking the API.
+  - API CHANGE: The alsa.preferPlugHW device config variable has been removed since it's not really useful for
+    anything anymore.
+  - ALSA: By default, device enumeration will now only enumerate over unique card/device pairs. Applications
+    can enable verbose device enumeration by setting the alsa.useVerboseDeviceEnumeration context config
+    variable.
+  - ALSA: When opening a device in shared mode (the default), the dmix/dsnoop plugin will be prioritized. If
+    this fails it will fall back to the hw plugin. With this change the preferExclusiveMode config is now
+    honored. Note that this does not happen when alsa.useVerboseDeviceEnumeration is set to true (see above)
+    which is by design.
+  - ALSA: Add support for excluding the "null" device using the alsa.excludeNullDevice context config variable.
+  - ALSA: Fix a bug with channel mapping which causes an assertion to fail.
+  - Fix errors with enumeration when pInfo is set to NULL.
+  - OSS: Fix a bug when starting a device when the client sends 0 samples for the initial buffer fill.
+
+v0.4 - 2017-11-05
+  - API CHANGE: The log callback is now per-context rather than per-device and as is thus now passed to
+    mal_context_init(). The rationale for this change is that it allows applications to capture diagnostic
+    messages at the context level. Previously this was only available at the device level.
+  - API CHANGE: The device config passed to mal_device_init() is now const.
+  - Added support for OSS which enables support on BSD platforms.
+  - Added support for WinMM (waveOut/waveIn).
+  - Added support for UWP (Universal Windows Platform) applications. Currently C++ only.
+  - Added support for exclusive mode for selected backends. Currently supported on WASAPI.
+  - POSIX builds no longer require explicit linking to libpthread (-lpthread).
+  - ALSA: Explicit linking to libasound (-lasound) is no longer required.
+  - ALSA: Latency improvements.
+  - ALSA: Use MMAP mode where available. This can be disabled with the alsa.noMMap config.
+  - ALSA: Use "hw" devices instead of "plughw" devices by default. This can be disabled with the
+    alsa.preferPlugHW config.
+  - WASAPI is now the highest priority backend on Windows platforms.
+  - Fixed an error with sample rate conversion which was causing crackling when capturing.
+  - Improved error handling.
+  - Improved compiler support.
+  - Miscellaneous bug fixes.
+
+v0.3 - 2017-06-19
+  - API CHANGE: Introduced the notion of a context. The context is the highest level object and is required for
+    enumerating and creating devices. Now, applications must first create a context, and then use that to
+    enumerate and create devices. The reason for this change is to ensure device enumeration and creation is
+    tied to the same backend. In addition, some backends are better suited to this design.
+  - API CHANGE: Removed the rewinding APIs because they're too inconsistent across the different backends, hard
+    to test and maintain, and just generally unreliable.
+  - Added helper APIs for initializing mal_device_config objects.
+  - Null Backend: Fixed a crash when recording.
+  - Fixed build for UWP.
+  - Added support for f32 formats to the OpenSL|ES backend.
+  - Added initial implementation of the WASAPI backend.
+  - Added initial implementation of the OpenAL backend.
+  - Added support for low quality linear sample rate conversion.
+  - Added early support for basic channel mapping.
+
+v0.2 - 2016-10-28
+  - API CHANGE: Add user data pointer as the last parameter to mal_device_init(). The rationale for this
+    change is to ensure the logging callback has access to the user data during initialization.
+  - API CHANGE: Have device configuration properties be passed to mal_device_init() via a structure. Rationale:
+    1) The number of parameters is just getting too much.
+    2) It makes it a bit easier to add new configuration properties in the future. In particular, there's a
+       chance there will be support added for backend-specific properties.
+  - Dropped support for f64, A-law and Mu-law formats since they just aren't common enough to justify the
+    added maintenance cost.
+  - DirectSound: Increased the default buffer size for capture devices.
+  - Added initial implementation of the OpenSL|ES backend.
+
+v0.1 - 2016-10-21
+  - Initial versioned release.

+
+ MISSION STATEMENT
+ =================
+
+ - Easy to use to create code-driven and data-driven tools.
+ - Easy to use to create ad hoc short-lived tools and long-lived, more elaborate tools.
+ - Easy to hack and improve.
+ - Minimize screen real-estate usage.
+ - Minimize setup and maintenance.
+ - Minimize state storage on user side.
+ - Portable, minimize dependencies, run on target (consoles, phones, etc.).
+ - Efficient runtime and memory consumption (NB- we do allocate when "growing" content e.g. creating a window,.
+   opening a tree node for the first time, etc. but a typical frame should not allocate anything).
+
+ Designed for developers and content-creators, not the typical end-user! Some of the weaknesses includes:
+ - Doesn't look fancy, doesn't animate.
+ - Limited layout features, intricate layouts are typically crafted in code.
+
+
+ END-USER GUIDE
+ ==============
+
+ - Double-click on title bar to collapse window.
+ - Click upper right corner to close a window, available when 'bool* p_open' is passed to ImGui::Begin().
+ - Click and drag on lower right corner to resize window (double-click to auto fit window to its contents).
+ - Click and drag on any empty space to move window.
+ - TAB/SHIFT+TAB to cycle through keyboard editable fields.
+ - CTRL+Click on a slider or drag box to input value as text.
+ - Use mouse wheel to scroll.
+ - Text editor:
+   - Hold SHIFT or use mouse to select text.
+   - CTRL+Left/Right to word jump.
+   - CTRL+Shift+Left/Right to select words.
+   - CTRL+A our Double-Click to select all.
+   - CTRL+X,CTRL+C,CTRL+V to use OS clipboard/
+   - CTRL+Z,CTRL+Y to undo/redo.
+   - ESCAPE to revert text to its original value.
+   - You can apply arithmetic operators +,*,/ on numerical values. Use +- to subtract (because - would set a negative value!)
+   - Controls are automatically adjusted for OSX to match standard OSX text editing operations.
+ - General Keyboard controls: enable with ImGuiConfigFlags_NavEnableKeyboard.
+ - General Gamepad controls: enable with ImGuiConfigFlags_NavEnableGamepad. See suggested mappings in imgui.h ImGuiNavInput_ + download PNG/PSD at http://goo.gl/9LgVZW
+
+
+ PROGRAMMER GUIDE
+ ================
+
+ READ FIRST
+ ----------
+ - Remember to read the FAQ (https://www.dearimgui.org/faq)
+ - Your code creates the UI, if your code doesn't run the UI is gone! The UI can be highly dynamic, there are no construction
+   or destruction steps, less superfluous data retention on your side, less state duplication, less state synchronization, less bugs.
+ - Call and read ImGui::ShowDemoWindow() for demo code demonstrating most features.
+ - The library is designed to be built from sources. Avoid pre-compiled binaries and packaged versions. See imconfig.h to configure your build.
+ - Dear ImGui is an implementation of the IMGUI paradigm (immediate-mode graphical user interface, a term coined by Casey Muratori).
+   You can learn about IMGUI principles at http://www.johno.se/book/imgui.html, http://mollyrocket.com/861 & more links docs/README.md.
+ - Dear ImGui is a "single pass" rasterizing implementation of the IMGUI paradigm, aimed at ease of use and high-performances.
+   For every application frame your UI code will be called only once. This is in contrast to e.g. Unity's own implementation of an IMGUI,
+   where the UI code is called multiple times ("multiple passes") from a single entry point. There are pros and cons to both approaches.
+ - Our origin are on the top-left. In axis aligned bounding boxes, Min = top-left, Max = bottom-right.
+ - This codebase is also optimized to yield decent performances with typical "Debug" builds settings.
+ - Please make sure you have asserts enabled (IM_ASSERT redirects to assert() by default, but can be redirected).
+   If you get an assert, read the messages and comments around the assert.
+ - C++: this is a very C-ish codebase: we don't rely on C++11, we don't include any C++ headers, and ImGui:: is a namespace.
+ - C++: ImVec2/ImVec4 do not expose math operators by default, because it is expected that you use your own math types.
+   See FAQ "How can I use my own math types instead of ImVec2/ImVec4?" for details about setting up imconfig.h for that.
+   However, imgui_internal.h can optionally export math operators for ImVec2/ImVec4, which we use in this codebase.
+ - C++: pay attention that ImVector<> manipulates plain-old-data and does not honor construction/destruction (avoid using it in your code!).
+
+ HOW TO UPDATE TO A NEWER VERSION OF DEAR IMGUI
+ ----------------------------------------------
+ - Overwrite all the sources files except for imconfig.h (if you have made modification to your copy of imconfig.h)
+ - Or maintain your own branch where you have imconfig.h modified.
+ - Read the "API BREAKING CHANGES" section (below). This is where we list occasional API breaking changes.
+   If a function/type has been renamed / or marked obsolete, try to fix the name in your code before it is permanently removed
+   from the public API. If you have a problem with a missing function/symbols, search for its name in the code, there will
+   likely be a comment about it. Please report any issue to the GitHub page!
+ - Try to keep your copy of dear imgui reasonably up to date.
+
+ GETTING STARTED WITH INTEGRATING DEAR IMGUI IN YOUR CODE/ENGINE
+ ---------------------------------------------------------------
+ - Run and study the examples and demo in imgui_demo.cpp to get acquainted with the library.
+ - In the majority of cases you should be able to use unmodified back-ends files available in the examples/ folder.
+ - Add the Dear ImGui source files to your projects or using your preferred build system.
+   It is recommended you build and statically link the .cpp files as part of your project and NOT as shared library (DLL).
+ - You can later customize the imconfig.h file to tweak some compile-time behavior, such as integrating Dear ImGui types with your own maths types.
+ - When using Dear ImGui, your programming IDE is your friend: follow the declaration of variables, functions and types to find comments about them.
+ - Dear ImGui never touches or knows about your GPU state. The only function that knows about GPU is the draw function that you provide.
+   Effectively it means you can create widgets at any time in your code, regardless of considerations of being in "update" vs "render"
+   phases of your own application. All rendering information are stored into command-lists that you will retrieve after calling ImGui::Render().
+ - Refer to the bindings and demo applications in the examples/ folder for instruction on how to setup your code.
+ - If you are running over a standard OS with a common graphics API, you should be able to use unmodified imgui_impl_*** files from the examples/ folder.
+
+ HOW A SIMPLE APPLICATION MAY LOOK LIKE
+ --------------------------------------
+ EXHIBIT 1: USING THE EXAMPLE BINDINGS (imgui_impl_XXX.cpp files from the examples/ folder).
+
+     // Application init: create a dear imgui context, setup some options, load fonts
+     ImGui::CreateContext();
+     ImGuiIO& io = ImGui::GetIO();
+     // TODO: Set optional io.ConfigFlags values, e.g. 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard' to enable keyboard controls.
+     // TODO: Fill optional fields of the io structure later.
+     // TODO: Load TTF/OTF fonts if you don't want to use the default font.
+
+     // Initialize helper Platform and Renderer bindings (here we are using imgui_impl_win32.cpp and imgui_impl_dx11.cpp)
+     ImGui_ImplWin32_Init(hwnd);
+     ImGui_ImplDX11_Init(g_pd3dDevice, g_pd3dDeviceContext);
+
+     // Application main loop
+     while (true)
+     {
+         // Feed inputs to dear imgui, start new frame
+         ImGui_ImplDX11_NewFrame();
+         ImGui_ImplWin32_NewFrame();
+         ImGui::NewFrame();
+
+         // Any application code here
+         ImGui::Text("Hello, world!");
+
+         // Render dear imgui into screen
+         ImGui::Render();
+         ImGui_ImplDX11_RenderDrawData(ImGui::GetDrawData());
+         g_pSwapChain->Present(1, 0);
+     }
+
+     // Shutdown
+     ImGui_ImplDX11_Shutdown();
+     ImGui_ImplWin32_Shutdown();
+     ImGui::DestroyContext();
+
+ EXHIBIT 2: IMPLEMENTING CUSTOM BINDING / CUSTOM ENGINE
+
+     // Application init: create a dear imgui context, setup some options, load fonts
+     ImGui::CreateContext();
+     ImGuiIO& io = ImGui::GetIO();
+     // TODO: Set optional io.ConfigFlags values, e.g. 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard' to enable keyboard controls.

+     // After we have created the texture, store its pointer/identifier (_in whichever format your engine uses_) in 'io.Fonts->TexID'.
+     // This will be passed back to your via the renderer. Basically ImTextureID == void*. Read FAQ for details about ImTextureID.
+     MyTexture* texture = MyEngine::CreateTextureFromMemoryPixels(pixels, width, height, TEXTURE_TYPE_RGBA32)
+     io.Fonts->TexID = (void*)texture;
+
+     // Application main loop
+     while (true)
+     {
+        // Setup low-level inputs, e.g. on Win32: calling GetKeyboardState(), or write to those fields from your Windows message handlers, etc.
+        // (In the examples/ app this is usually done within the ImGui_ImplXXX_NewFrame() function from one of the demo Platform bindings)
+        io.DeltaTime = 1.0f/60.0f;              // set the time elapsed since the previous frame (in seconds)
+        io.DisplaySize.x = 1920.0f;             // set the current display width
+        io.DisplaySize.y = 1280.0f;             // set the current display height here
+        io.MousePos = my_mouse_pos;             // set the mouse position
+        io.MouseDown[0] = my_mouse_buttons[0];  // set the mouse button states
+        io.MouseDown[1] = my_mouse_buttons[1];
+
+        // Call NewFrame(), after this point you can use ImGui::* functions anytime
+        // (So you want to try calling NewFrame() as early as you can in your mainloop to be able to use Dear ImGui everywhere)
+        ImGui::NewFrame();
+
+        // Most of your application code here
+        ImGui::Text("Hello, world!");
+        MyGameUpdate(); // may use any Dear ImGui functions, e.g. ImGui::Begin("My window"); ImGui::Text("Hello, world!"); ImGui::End();
+        MyGameRender(); // may use any Dear ImGui functions as well!
+
+        // Render dear imgui, swap buffers
+        // (You want to try calling EndFrame/Render as late as you can, to be able to use Dear ImGui in your own game rendering code)
+        ImGui::EndFrame();
+        ImGui::Render();
+        ImDrawData* draw_data = ImGui::GetDrawData();
+        MyImGuiRenderFunction(draw_data);
+        SwapBuffers();
+     }

+             if (pcmd->UserCallback)
+             {
+                 pcmd->UserCallback(cmd_list, pcmd);
+             }
+             else
+             {

+                 // The vast majority of draw calls will use the Dear ImGui texture atlas, which value you have set yourself during initialization.

+                 //   (some elements visible outside their bounds) but you can fix that once everything else works!
+                 // - Clipping coordinates are provided in imgui coordinates space (from draw_data->DisplayPos to draw_data->DisplayPos + draw_data->DisplaySize)

+                 //   However, in the interest of supporting multi-viewport applications in the future (see 'viewport' branch on github),
+                 //   always subtract draw_data->DisplayPos from clipping bounds to convert them to your viewport space.
+                 // - Note that pcmd->ClipRect contains Min+Max bounds. Some graphics API may use Min+Max, other may use Min+Size (size being Max-Min)

+                 MyEngineDrawIndexedTriangles(pcmd->ElemCount, sizeof(ImDrawIdx) == 2 ? GL_UNSIGNED_SHORT : GL_UNSIGNED_INT, idx_buffer, vtx_buffer);
+             }
+             idx_buffer += pcmd->ElemCount;
+          }
+       }
+    }
+
+ - The examples/ folders contains many actual implementation of the pseudo-codes above.
+ - When calling NewFrame(), the 'io.WantCaptureMouse', 'io.WantCaptureKeyboard' and 'io.WantTextInput' flags are updated.
+   They tell you if Dear ImGui intends to use your inputs. When a flag is set you want to hide the corresponding inputs from the
+   rest of your application. In every cases you need to pass on the inputs to Dear ImGui.
+ - Refer to the FAQ for more information. Amusingly, it is called a FAQ because people frequently run into the same issues!
+
+ USING GAMEPAD/KEYBOARD NAVIGATION CONTROLS
+ ------------------------------------------
+ - The gamepad/keyboard navigation is fairly functional and keeps being improved.
+ - Gamepad support is particularly useful to use Dear ImGui on a console system (e.g. PS4, Switch, XB1) without a mouse!
+ - You can ask questions and report issues at https://github.com/ocornut/imgui/issues/787
+ - The initial focus was to support game controllers, but keyboard is becoming increasingly and decently usable.
+ - Keyboard:
+    - Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard to enable.
+      NewFrame() will automatically fill io.NavInputs[] based on your io.KeysDown[] + io.KeyMap[] arrays.
+    - When keyboard navigation is active (io.NavActive + ImGuiConfigFlags_NavEnableKeyboard), the io.WantCaptureKeyboard flag
+      will be set. For more advanced uses, you may want to read from:
+       - io.NavActive: true when a window is focused and it doesn't have the ImGuiWindowFlags_NoNavInputs flag set.
+       - io.NavVisible: true when the navigation cursor is visible (and usually goes false when mouse is used).
+       - or query focus information with e.g. IsWindowFocused(ImGuiFocusedFlags_AnyWindow), IsItemFocused() etc. functions.
+      Please reach out if you think the game vs navigation input sharing could be improved.
+ - Gamepad:
+    - Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad to enable.
+    - Backend: Set io.BackendFlags |= ImGuiBackendFlags_HasGamepad + fill the io.NavInputs[] fields before calling NewFrame().
+      Note that io.NavInputs[] is cleared by EndFrame().
+    - See 'enum ImGuiNavInput_' in imgui.h for a description of inputs. For each entry of io.NavInputs[], set the following values:
+         0.0f= not held. 1.0f= fully held. Pass intermediate 0.0f..1.0f values for analog triggers/sticks.
+    - We uses a simple >0.0f test for activation testing, and won't attempt to test for a dead-zone.
+      Your code will probably need to transform your raw inputs (such as e.g. remapping your 0.2..0.9 raw input range to 0.0..1.0 imgui range, etc.).
+    - You can download PNG/PSD files depicting the gamepad controls for common controllers at: http://goo.gl/9LgVZW.
+    - If you need to share inputs between your game and the imgui parts, the easiest approach is to go all-or-nothing, with a buttons combo
+      to toggle the target. Please reach out if you think the game vs navigation input sharing could be improved.
+ - Mouse:
+    - PS4 users: Consider emulating a mouse cursor with DualShock4 touch pad or a spare analog stick as a mouse-emulation fallback.
+    - Consoles/Tablet/Phone users: Consider using a Synergy 1.x server (on your PC) + uSynergy.c (on your console/tablet/phone app) to share your PC mouse/keyboard.
+    - On a TV/console system where readability may be lower or mouse inputs may be awkward, you may want to set the ImGuiConfigFlags_NavEnableSetMousePos flag.
+      Enabling ImGuiConfigFlags_NavEnableSetMousePos + ImGuiBackendFlags_HasSetMousePos instructs dear imgui to move your mouse cursor along with navigation movements.
+      When enabled, the NewFrame() function may alter 'io.MousePos' and set 'io.WantSetMousePos' to notify you that it wants the mouse cursor to be moved.
+      When that happens your back-end NEEDS to move the OS or underlying mouse cursor on the next frame. Some of the binding in examples/ do that.
+      (If you set the NavEnableSetMousePos flag but don't honor 'io.WantSetMousePos' properly, imgui will misbehave as it will see your mouse as moving back and forth!)
+      (In a setup when you may not have easy control over the mouse cursor, e.g. uSynergy.c doesn't expose moving remote mouse cursor, you may want
+       to set a boolean to ignore your other external mouse positions until the external source is moved again.)
+
+
+ API BREAKING CHANGES
+ ====================
+
+ Occasionally introducing changes that are breaking the API. We try to make the breakage minor and easy to fix.
+ Below is a change-log of API breaking changes only. If you are using one of the functions listed, expect to have to fix some code.
+ When you are not sure about a old symbol or function name, try using the Search/Find function of your IDE to look for comments or references in all imgui files.
+ You can read releases logs https://github.com/ocornut/imgui/releases for more details.
+
+ - 2020/01/22 (1.75) - ImDrawList::AddCircle()/AddCircleFilled() functions don't accept negative radius any more.
+ - 2019/12/17 (1.75) - made Columns() limited to 64 columns by asserting above that limit. While the current code technically supports it, future code may not so we're putting the restriction ahead.
+ - 2019/12/13 (1.75) - [imgui_internal.h] changed ImRect() default constructor initializes all fields to 0.0f instead of (FLT_MAX,FLT_MAX,-FLT_MAX,-FLT_MAX). If you used ImRect::Add() to create bounding boxes by adding multiple points into it, you may need to fix your initial value.
+ - 2019/12/08 (1.75) - removed redirecting functions/enums that were marked obsolete in 1.53 (December 2017):
+                       - ShowTestWindow()                    -> use ShowDemoWindow()
+                       - IsRootWindowFocused()               -> use IsWindowFocused(ImGuiFocusedFlags_RootWindow)
+                       - IsRootWindowOrAnyChildFocused()     -> use IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows)
+                       - SetNextWindowContentWidth(w)        -> use SetNextWindowContentSize(ImVec2(w, 0.0f)
+                       - GetItemsLineHeightWithSpacing()     -> use GetFrameHeightWithSpacing()
+                       - ImGuiCol_ChildWindowBg              -> use ImGuiCol_ChildBg
+                       - ImGuiStyleVar_ChildWindowRounding   -> use ImGuiStyleVar_ChildRounding
+                       - ImGuiTreeNodeFlags_AllowOverlapMode -> use ImGuiTreeNodeFlags_AllowItemOverlap
+                       - IMGUI_DISABLE_TEST_WINDOWS          -> use IMGUI_DISABLE_DEMO_WINDOWS
+ - 2019/12/08 (1.75) - obsoleted calling ImDrawList::PrimReserve() with a negative count (which was the vaguely documented and rarely if ever used). Instead we added an explicit PrimUnreserve() API.
+ - 2019/12/06 (1.75) - removed implicit default parameter to IsMouseDragging(int button = 0) to be consistent with other mouse functions (none of the other functions have it).
+ - 2019/11/21 (1.74) - ImFontAtlas::AddCustomRectRegular() now requires an ID larger than 0x110000 (instead of 0x10000) to conform with supporting Unicode planes 1-16 in a future update. ID below 0x110000 will now assert.
+ - 2019/11/19 (1.74) - renamed IMGUI_DISABLE_FORMAT_STRING_FUNCTIONS to IMGUI_DISABLE_DEFAULT_FORMAT_FUNCTIONS for consistency.
+ - 2019/11/19 (1.74) - renamed IMGUI_DISABLE_MATH_FUNCTIONS to IMGUI_DISABLE_DEFAULT_MATH_FUNCTIONS for consistency.
+ - 2019/10/22 (1.74) - removed redirecting functions/enums that were marked obsolete in 1.52 (October 2017):
+                       - Begin() [old 5 args version]        -> use Begin() [3 args], use SetNextWindowSize() SetNextWindowBgAlpha() if needed
+                       - IsRootWindowOrAnyChildHovered()     -> use IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows)
+                       - AlignFirstTextHeightToWidgets()     -> use AlignTextToFramePadding()
+                       - SetNextWindowPosCenter()            -> use SetNextWindowPos() with a pivot of (0.5f, 0.5f)
+                       - ImFont::Glyph                       -> use ImFontGlyph
+ - 2019/10/14 (1.74) - inputs: Fixed a miscalculation in the keyboard/mouse "typematic" repeat delay/rate calculation, used by keys and e.g. repeating mouse buttons as well as the GetKeyPressedAmount() function.
+                       if you were using a non-default value for io.KeyRepeatRate (previous default was 0.250), you can add +io.KeyRepeatDelay to it to compensate for the fix.
+                       The function was triggering on: 0.0 and (delay+rate*N) where (N>=1). Fixed formula responds to (N>=0). Effectively it made io.KeyRepeatRate behave like it was set to (io.KeyRepeatRate + io.KeyRepeatDelay).
+                       If you never altered io.KeyRepeatRate nor used GetKeyPressedAmount() this won't affect you.
+ - 2019/07/15 (1.72) - removed TreeAdvanceToLabelPos() which is rarely used and only does SetCursorPosX(GetCursorPosX() + GetTreeNodeToLabelSpacing()). Kept redirection function (will obsolete).
+ - 2019/07/12 (1.72) - renamed ImFontAtlas::CustomRect to ImFontAtlasCustomRect. Kept redirection typedef (will obsolete).
+ - 2019/06/14 (1.72) - removed redirecting functions/enums names that were marked obsolete in 1.51 (June 2017): ImGuiCol_Column*, ImGuiSetCond_*, IsItemHoveredRect(), IsPosHoveringAnyWindow(), IsMouseHoveringAnyWindow(), IsMouseHoveringWindow(), IMGUI_ONCE_UPON_A_FRAME. Grep this log for details and new names, or see how they were implemented until 1.71.
+ - 2019/06/07 (1.71) - rendering of child window outer decorations (bg color, border, scrollbars) is now performed as part of the parent window. If you have
+                       overlapping child windows in a same parent, and relied on their relative z-order to be mapped to their submission order, this will affect your rendering.
+                       This optimization is disabled if the parent window has no visual output, because it appears to be the most common situation leading to the creation of overlapping child windows.
+                       Please reach out if you are affected.
+ - 2019/05/13 (1.71) - renamed SetNextTreeNodeOpen() to SetNextItemOpen(). Kept inline redirection function (will obsolete).
+ - 2019/05/11 (1.71) - changed io.AddInputCharacter(unsigned short c) signature to io.AddInputCharacter(unsigned int c).
+ - 2019/04/29 (1.70) - improved ImDrawList thick strokes (>1.0f) preserving correct thickness up to 90 degrees angles (e.g. rectangles). If you have custom rendering using thick lines, they will appear thicker now.
+ - 2019/04/29 (1.70) - removed GetContentRegionAvailWidth(), use GetContentRegionAvail().x instead. Kept inline redirection function (will obsolete).
+ - 2019/03/04 (1.69) - renamed GetOverlayDrawList() to GetForegroundDrawList(). Kept redirection function (will obsolete).
+ - 2019/02/26 (1.69) - renamed ImGuiColorEditFlags_RGB/ImGuiColorEditFlags_HSV/ImGuiColorEditFlags_HEX to ImGuiColorEditFlags_DisplayRGB/ImGuiColorEditFlags_DisplayHSV/ImGuiColorEditFlags_DisplayHex. Kept redirection enums (will obsolete).
+ - 2019/02/14 (1.68) - made it illegal/assert when io.DisplayTime == 0.0f (with an exception for the first frame). If for some reason your time step calculation gives you a zero value, replace it with a dummy small value!
+ - 2019/02/01 (1.68) - removed io.DisplayVisibleMin/DisplayVisibleMax (which were marked obsolete and removed from viewport/docking branch already).
+ - 2019/01/06 (1.67) - renamed io.InputCharacters[], marked internal as was always intended. Please don't access directly, and use AddInputCharacter() instead!
+ - 2019/01/06 (1.67) - renamed ImFontAtlas::GlyphRangesBuilder to ImFontGlyphRangesBuilder. Kept redirection typedef (will obsolete).
+ - 2018/12/20 (1.67) - made it illegal to call Begin("") with an empty string. This somehow half-worked before but had various undesirable side-effects.
+ - 2018/12/10 (1.67) - renamed io.ConfigResizeWindowsFromEdges to io.ConfigWindowsResizeFromEdges as we are doing a large pass on configuration flags.
+ - 2018/10/12 (1.66) - renamed misc/stl/imgui_stl.* to misc/cpp/imgui_stdlib.* in prevision for other C++ helper files.
+ - 2018/09/28 (1.66) - renamed SetScrollHere() to SetScrollHereY(). Kept redirection function (will obsolete).
+ - 2018/09/06 (1.65) - renamed stb_truetype.h to imstb_truetype.h, stb_textedit.h to imstb_textedit.h, and stb_rect_pack.h to imstb_rectpack.h.
+                       If you were conveniently using the imgui copy of those STB headers in your project you will have to update your include paths.
+ - 2018/09/05 (1.65) - renamed io.OptCursorBlink/io.ConfigCursorBlink to io.ConfigInputTextCursorBlink. (#1427)
+ - 2018/08/31 (1.64) - added imgui_widgets.cpp file, extracted and moved widgets code out of imgui.cpp into imgui_widgets.cpp. Re-ordered some of the code remaining in imgui.cpp.
+                       NONE OF THE FUNCTIONS HAVE CHANGED. THE CODE IS SEMANTICALLY 100% IDENTICAL, BUT _EVERY_ FUNCTION HAS BEEN MOVED.
+                       Because of this, any local modifications to imgui.cpp will likely conflict when you update. Read docs/CHANGELOG.txt for suggestions.
+ - 2018/08/22 (1.63) - renamed IsItemDeactivatedAfterChange() to IsItemDeactivatedAfterEdit() for consistency with new IsItemEdited() API. Kept redirection function (will obsolete soonish as IsItemDeactivatedAfterChange() is very recent).
+ - 2018/08/21 (1.63) - renamed ImGuiTextEditCallback to ImGuiInputTextCallback, ImGuiTextEditCallbackData to ImGuiInputTextCallbackData for consistency. Kept redirection types (will obsolete).
+ - 2018/08/21 (1.63) - removed ImGuiInputTextCallbackData::ReadOnly since it is a duplication of (ImGuiInputTextCallbackData::Flags & ImGuiInputTextFlags_ReadOnly).
+ - 2018/08/01 (1.63) - removed per-window ImGuiWindowFlags_ResizeFromAnySide beta flag in favor of a global io.ConfigResizeWindowsFromEdges [update 1.67 renamed to ConfigWindowsResizeFromEdges] to enable the feature.
+ - 2018/08/01 (1.63) - renamed io.OptCursorBlink to io.ConfigCursorBlink [-> io.ConfigInputTextCursorBlink in 1.65], io.OptMacOSXBehaviors to ConfigMacOSXBehaviors for consistency.
+ - 2018/07/22 (1.63) - changed ImGui::GetTime() return value from float to double to avoid accumulating floating point imprecisions over time.
+ - 2018/07/08 (1.63) - style: renamed ImGuiCol_ModalWindowDarkening to ImGuiCol_ModalWindowDimBg for consistency with other features. Kept redirection enum (will obsolete).
+ - 2018/06/08 (1.62) - examples: the imgui_impl_xxx files have been split to separate platform (Win32, Glfw, SDL2, etc.) from renderer (DX11, OpenGL, Vulkan,  etc.).
+                       old bindings will still work as is, however prefer using the separated bindings as they will be updated to support multi-viewports.
+                       when adopting new bindings follow the main.cpp code of your preferred examples/ folder to know which functions to call.
+                       in particular, note that old bindings called ImGui::NewFrame() at the end of their ImGui_ImplXXXX_NewFrame() function.
+ - 2018/06/06 (1.62) - renamed GetGlyphRangesChinese() to GetGlyphRangesChineseFull() to distinguish other variants and discourage using the full set.
+ - 2018/06/06 (1.62) - TreeNodeEx()/TreeNodeBehavior(): the ImGuiTreeNodeFlags_CollapsingHeader helper now include the ImGuiTreeNodeFlags_NoTreePushOnOpen flag. See Changelog for details.
+ - 2018/05/03 (1.61) - DragInt(): the default compile-time format string has been changed from "%.0f" to "%d", as we are not using integers internally any more.
+                       If you used DragInt() with custom format strings, make sure you change them to use %d or an integer-compatible format.
+                       To honor backward-compatibility, the DragInt() code will currently parse and modify format strings to replace %*f with %d, giving time to users to upgrade their code.
+                       If you have IMGUI_DISABLE_OBSOLETE_FUNCTIONS enabled, the code will instead assert! You may run a reg-exp search on your codebase for e.g. "DragInt.*%f" to help you find them.
+ - 2018/04/28 (1.61) - obsoleted InputFloat() functions taking an optional "int decimal_precision" in favor of an equivalent and more flexible "const char* format",
+                       consistent with other functions. Kept redirection functions (will obsolete).
+ - 2018/04/09 (1.61) - IM_DELETE() helper function added in 1.60 doesn't clear the input _pointer_ reference, more consistent with expectation and allows passing r-value.
+ - 2018/03/20 (1.60) - renamed io.WantMoveMouse to io.WantSetMousePos for consistency and ease of understanding (was added in 1.52, _not_ used by core and only honored by some binding ahead of merging the Nav branch).
+ - 2018/03/12 (1.60) - removed ImGuiCol_CloseButton, ImGuiCol_CloseButtonActive, ImGuiCol_CloseButtonHovered as the closing cross uses regular button colors now.
+ - 2018/03/08 (1.60) - changed ImFont::DisplayOffset.y to default to 0 instead of +1. Fixed rounding of Ascent/Descent to match TrueType renderer. If you were adding or subtracting to ImFont::DisplayOffset check if your fonts are correctly aligned vertically.
+ - 2018/03/03 (1.60) - renamed ImGuiStyleVar_Count_ to ImGuiStyleVar_COUNT and ImGuiMouseCursor_Count_ to ImGuiMouseCursor_COUNT for consistency with other public enums.
+ - 2018/02/18 (1.60) - BeginDragDropSource(): temporarily removed the optional mouse_button=0 parameter because it is not really usable in many situations at the moment.
+ - 2018/02/16 (1.60) - obsoleted the io.RenderDrawListsFn callback, you can call your graphics engine render function after ImGui::Render(). Use ImGui::GetDrawData() to retrieve the ImDrawData* to display.
+ - 2018/02/07 (1.60) - reorganized context handling to be more explicit,
+                       - YOU NOW NEED TO CALL ImGui::CreateContext() AT THE BEGINNING OF YOUR APP, AND CALL ImGui::DestroyContext() AT THE END.
+                       - removed Shutdown() function, as DestroyContext() serve this purpose.
+                       - you may pass a ImFontAtlas* pointer to CreateContext() to share a font atlas between contexts. Otherwise CreateContext() will create its own font atlas instance.
+                       - removed allocator parameters from CreateContext(), they are now setup with SetAllocatorFunctions(), and shared by all contexts.
+                       - removed the default global context and font atlas instance, which were confusing for users of DLL reloading and users of multiple contexts.
+ - 2018/01/31 (1.60) - moved sample TTF files from extra_fonts/ to misc/fonts/. If you loaded files directly from the imgui repo you may need to update your paths.
+ - 2018/01/11 (1.60) - obsoleted IsAnyWindowHovered() in favor of IsWindowHovered(ImGuiHoveredFlags_AnyWindow). Kept redirection function (will obsolete).
+ - 2018/01/11 (1.60) - obsoleted IsAnyWindowFocused() in favor of IsWindowFocused(ImGuiFocusedFlags_AnyWindow). Kept redirection function (will obsolete).
+ - 2018/01/03 (1.60) - renamed ImGuiSizeConstraintCallback to ImGuiSizeCallback, ImGuiSizeConstraintCallbackData to ImGuiSizeCallbackData.
+ - 2017/12/29 (1.60) - removed CalcItemRectClosestPoint() which was weird and not really used by anyone except demo code. If you need it it's easy to replicate on your side.
+ - 2017/12/24 (1.53) - renamed the emblematic ShowTestWindow() function to ShowDemoWindow(). Kept redirection function (will obsolete).
+ - 2017/12/21 (1.53) - ImDrawList: renamed style.AntiAliasedShapes to style.AntiAliasedFill for consistency and as a way to explicitly break code that manipulate those flag at runtime. You can now manipulate ImDrawList::Flags
+ - 2017/12/21 (1.53) - ImDrawList: removed 'bool anti_aliased = true' final parameter of ImDrawList::AddPolyline() and ImDrawList::AddConvexPolyFilled(). Prefer manipulating ImDrawList::Flags if you need to toggle them during the frame.
+ - 2017/12/14 (1.53) - using the ImGuiWindowFlags_NoScrollWithMouse flag on a child window forwards the mouse wheel event to the parent window, unless either ImGuiWindowFlags_NoInputs or ImGuiWindowFlags_NoScrollbar are also set.
+ - 2017/12/13 (1.53) - renamed GetItemsLineHeightWithSpacing() to GetFrameHeightWithSpacing(). Kept redirection function (will obsolete).
+ - 2017/12/13 (1.53) - obsoleted IsRootWindowFocused() in favor of using IsWindowFocused(ImGuiFocusedFlags_RootWindow). Kept redirection function (will obsolete).
+                     - obsoleted IsRootWindowOrAnyChildFocused() in favor of using IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows). Kept redirection function (will obsolete).
+ - 2017/12/12 (1.53) - renamed ImGuiTreeNodeFlags_AllowOverlapMode to ImGuiTreeNodeFlags_AllowItemOverlap. Kept redirection enum (will obsolete).
+ - 2017/12/10 (1.53) - removed SetNextWindowContentWidth(), prefer using SetNextWindowContentSize(). Kept redirection function (will obsolete).
+ - 2017/11/27 (1.53) - renamed ImGuiTextBuffer::append() helper to appendf(), appendv() to appendfv(). If you copied the 'Log' demo in your code, it uses appendv() so that needs to be renamed.
+ - 2017/11/18 (1.53) - Style, Begin: removed ImGuiWindowFlags_ShowBorders window flag. Borders are now fully set up in the ImGuiStyle structure (see e.g. style.FrameBorderSize, style.WindowBorderSize). Use ImGui::ShowStyleEditor() to look them up.
+                       Please note that the style system will keep evolving (hopefully stabilizing in Q1 2018), and so custom styles will probably subtly break over time. It is recommended you use the StyleColorsClassic(), StyleColorsDark(), StyleColorsLight() functions.
+ - 2017/11/18 (1.53) - Style: removed ImGuiCol_ComboBg in favor of combo boxes using ImGuiCol_PopupBg for consistency.
+ - 2017/11/18 (1.53) - Style: renamed ImGuiCol_ChildWindowBg to ImGuiCol_ChildBg.
+ - 2017/11/18 (1.53) - Style: renamed style.ChildWindowRounding to style.ChildRounding, ImGuiStyleVar_ChildWindowRounding to ImGuiStyleVar_ChildRounding.
+ - 2017/11/02 (1.53) - obsoleted IsRootWindowOrAnyChildHovered() in favor of using IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows);
+ - 2017/10/24 (1.52) - renamed IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCS to IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCTIONS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS for consistency.
+ - 2017/10/20 (1.52) - changed IsWindowHovered() default parameters behavior to return false if an item is active in another window (e.g. click-dragging item from another window to this window). You can use the newly introduced IsWindowHovered() flags to requests this specific behavior if you need it.
+ - 2017/10/20 (1.52) - marked IsItemHoveredRect()/IsMouseHoveringWindow() as obsolete, in favor of using the newly introduced flags for IsItemHovered() and IsWindowHovered(). See https://github.com/ocornut/imgui/issues/1382 for details.
+                       removed the IsItemRectHovered()/IsWindowRectHovered() names introduced in 1.51 since they were merely more consistent names for the two functions we are now obsoleting.
+                         IsItemHoveredRect()        --> IsItemHovered(ImGuiHoveredFlags_RectOnly)
+                         IsMouseHoveringAnyWindow() --> IsWindowHovered(ImGuiHoveredFlags_AnyWindow)
+                         IsMouseHoveringWindow()    --> IsWindowHovered(ImGuiHoveredFlags_AllowWhenBlockedByPopup | ImGuiHoveredFlags_AllowWhenBlockedByActiveItem) [weird, old behavior]
+ - 2017/10/17 (1.52) - marked the old 5-parameters version of Begin() as obsolete (still available). Use SetNextWindowSize()+Begin() instead!
+ - 2017/10/11 (1.52) - renamed AlignFirstTextHeightToWidgets() to AlignTextToFramePadding(). Kept inline redirection function (will obsolete).
+ - 2017/09/26 (1.52) - renamed ImFont::Glyph to ImFontGlyph. Kept redirection typedef (will obsolete).
+ - 2017/09/25 (1.52) - removed SetNextWindowPosCenter() because SetNextWindowPos() now has the optional pivot information to do the same and more. Kept redirection function (will obsolete).
+ - 2017/08/25 (1.52) - io.MousePos needs to be set to ImVec2(-FLT_MAX,-FLT_MAX) when mouse is unavailable/missing. Previously ImVec2(-1,-1) was enough but we now accept negative mouse coordinates. In your binding if you need to support unavailable mouse, make sure to replace "io.MousePos = ImVec2(-1,-1)" with "io.MousePos = ImVec2(-FLT_MAX,-FLT_MAX)".
+ - 2017/08/22 (1.51) - renamed IsItemHoveredRect() to IsItemRectHovered(). Kept inline redirection function (will obsolete). -> (1.52) use IsItemHovered(ImGuiHoveredFlags_RectOnly)!
+                     - renamed IsMouseHoveringAnyWindow() to IsAnyWindowHovered() for consistency. Kept inline redirection function (will obsolete).
+                     - renamed IsMouseHoveringWindow() to IsWindowRectHovered() for consistency. Kept inline redirection function (will obsolete).
+ - 2017/08/20 (1.51) - renamed GetStyleColName() to GetStyleColorName() for consistency.
+ - 2017/08/20 (1.51) - added PushStyleColor(ImGuiCol idx, ImU32 col) overload, which _might_ cause an "ambiguous call" compilation error if you are using ImColor() with implicit cast. Cast to ImU32 or ImVec4 explicily to fix.
+ - 2017/08/15 (1.51) - marked the weird IMGUI_ONCE_UPON_A_FRAME helper macro as obsolete. prefer using the more explicit ImGuiOnceUponAFrame type.
+ - 2017/08/15 (1.51) - changed parameter order for BeginPopupContextWindow() from (const char*,int buttons,bool also_over_items) to (const char*,int buttons,bool also_over_items). Note that most calls relied on default parameters completely.
+ - 2017/08/13 (1.51) - renamed ImGuiCol_Column to ImGuiCol_Separator, ImGuiCol_ColumnHovered to ImGuiCol_SeparatorHovered, ImGuiCol_ColumnActive to ImGuiCol_SeparatorActive. Kept redirection enums (will obsolete).
+ - 2017/08/11 (1.51) - renamed ImGuiSetCond_Always to ImGuiCond_Always, ImGuiSetCond_Once to ImGuiCond_Once, ImGuiSetCond_FirstUseEver to ImGuiCond_FirstUseEver, ImGuiSetCond_Appearing to ImGuiCond_Appearing. Kept redirection enums (will obsolete).
+ - 2017/08/09 (1.51) - removed ValueColor() helpers, they are equivalent to calling Text(label) + SameLine() + ColorButton().
+ - 2017/08/08 (1.51) - removed ColorEditMode() and ImGuiColorEditMode in favor of ImGuiColorEditFlags and parameters to the various Color*() functions. The SetColorEditOptions() allows to initialize default but the user can still change them with right-click context menu.
+                     - changed prototype of 'ColorEdit4(const char* label, float col[4], bool show_alpha = true)' to 'ColorEdit4(const char* label, float col[4], ImGuiColorEditFlags flags = 0)', where passing flags = 0x01 is a safe no-op (hello dodgy backward compatibility!). - check and run the demo window, under "Color/Picker Widgets", to understand the various new options.
+                     - changed prototype of rarely used 'ColorButton(ImVec4 col, bool small_height = false, bool outline_border = true)' to 'ColorButton(const char* desc_id, ImVec4 col, ImGuiColorEditFlags flags = 0, ImVec2 size = ImVec2(0,0))'
+ - 2017/07/20 (1.51) - removed IsPosHoveringAnyWindow(ImVec2), which was partly broken and misleading. ASSERT + redirect user to io.WantCaptureMouse
+ - 2017/05/26 (1.50) - removed ImFontConfig::MergeGlyphCenterV in favor of a more multipurpose ImFontConfig::GlyphOffset.
+ - 2017/05/01 (1.50) - renamed ImDrawList::PathFill() (rarely used directly) to ImDrawList::PathFillConvex() for clarity.
+ - 2016/11/06 (1.50) - BeginChild(const char*) now applies the stack id to the provided label, consistently with other functions as it should always have been. It shouldn't affect you unless (extremely unlikely) you were appending multiple times to a same child from different locations of the stack id. If that's the case, generate an id with GetId() and use it instead of passing string to BeginChild().
+ - 2016/10/15 (1.50) - avoid 'void* user_data' parameter to io.SetClipboardTextFn/io.GetClipboardTextFn pointers. We pass io.ClipboardUserData to it.
+ - 2016/09/25 (1.50) - style.WindowTitleAlign is now a ImVec2 (ImGuiAlign enum was removed). set to (0.5f,0.5f) for horizontal+vertical centering, (0.0f,0.0f) for upper-left, etc.
+ - 2016/07/30 (1.50) - SameLine(x) with x>0.0f is now relative to left of column/group if any, and not always to left of window. This was sort of always the intent and hopefully breakage should be minimal.
+ - 2016/05/12 (1.49) - title bar (using ImGuiCol_TitleBg/ImGuiCol_TitleBgActive colors) isn't rendered over a window background (ImGuiCol_WindowBg color) anymore.
+                       If your TitleBg/TitleBgActive alpha was 1.0f or you are using the default theme it will not affect you, otherwise if <1.0f you need tweak your custom theme to readjust for the fact that we don't draw a WindowBg background behind the title bar.
+                       This helper function will convert an old TitleBg/TitleBgActive color into a new one with the same visual output, given the OLD color and the OLD WindowBg color:
+                       ImVec4 ConvertTitleBgCol(const ImVec4& win_bg_col, const ImVec4& title_bg_col) { float new_a = 1.0f - ((1.0f - win_bg_col.w) * (1.0f - title_bg_col.w)), k = title_bg_col.w / new_a; return ImVec4((win_bg_col.x * win_bg_col.w + title_bg_col.x) * k, (win_bg_col.y * win_bg_col.w + title_bg_col.y) * k, (win_bg_col.z * win_bg_col.w + title_bg_col.z) * k, new_a); }
+                       If this is confusing, pick the RGB value from title bar from an old screenshot and apply this as TitleBg/TitleBgActive. Or you may just create TitleBgActive from a tweaked TitleBg color.
+ - 2016/05/07 (1.49) - removed confusing set of GetInternalState(), GetInternalStateSize(), SetInternalState() functions. Now using CreateContext(), DestroyContext(), GetCurrentContext(), SetCurrentContext().
+ - 2016/05/02 (1.49) - renamed SetNextTreeNodeOpened() to SetNextTreeNodeOpen(), no redirection.
+ - 2016/05/01 (1.49) - obsoleted old signature of CollapsingHeader(const char* label, const char* str_id = NULL, bool display_frame = true, bool default_open = false) as extra parameters were badly designed and rarely used. You can replace the "default_open = true" flag in new API with CollapsingHeader(label, ImGuiTreeNodeFlags_DefaultOpen).
+ - 2016/04/26 (1.49) - changed ImDrawList::PushClipRect(ImVec4 rect) to ImDrawList::PushClipRect(Imvec2 min,ImVec2 max,bool intersect_with_current_clip_rect=false). Note that higher-level ImGui::PushClipRect() is preferable because it will clip at logic/widget level, whereas ImDrawList::PushClipRect() only affect your renderer.
+ - 2016/04/03 (1.48) - removed style.WindowFillAlphaDefault setting which was redundant. Bake default BG alpha inside style.Colors[ImGuiCol_WindowBg] and all other Bg color values. (ref github issue #337).
+ - 2016/04/03 (1.48) - renamed ImGuiCol_TooltipBg to ImGuiCol_PopupBg, used by popups/menus and tooltips. popups/menus were previously using ImGuiCol_WindowBg. (ref github issue #337)
+ - 2016/03/21 (1.48) - renamed GetWindowFont() to GetFont(), GetWindowFontSize() to GetFontSize(). Kept inline redirection function (will obsolete).
+ - 2016/03/02 (1.48) - InputText() completion/history/always callbacks: if you modify the text buffer manually (without using DeleteChars()/InsertChars() helper) you need to maintain the BufTextLen field. added an assert.
+ - 2016/01/23 (1.48) - fixed not honoring exact width passed to PushItemWidth(), previously it would add extra FramePadding.x*2 over that width. if you had manual pixel-perfect alignment in place it might affect you.
+ - 2015/12/27 (1.48) - fixed ImDrawList::AddRect() which used to render a rectangle 1 px too large on each axis.
+ - 2015/12/04 (1.47) - renamed Color() helpers to ValueColor() - dangerously named, rarely used and probably to be made obsolete.
+ - 2015/08/29 (1.45) - with the addition of horizontal scrollbar we made various fixes to inconsistencies with dealing with cursor position.
+                       GetCursorPos()/SetCursorPos() functions now include the scrolled amount. It shouldn't affect the majority of users, but take note that SetCursorPosX(100.0f) puts you at +100 from the starting x position which may include scrolling, not at +100 from the window left side.
+                       GetContentRegionMax()/GetWindowContentRegionMin()/GetWindowContentRegionMax() functions allow include the scrolled amount. Typically those were used in cases where no scrolling would happen so it may not be a problem, but watch out!
+ - 2015/08/29 (1.45) - renamed style.ScrollbarWidth to style.ScrollbarSize
+ - 2015/08/05 (1.44) - split imgui.cpp into extra files: imgui_demo.cpp imgui_draw.cpp imgui_internal.h that you need to add to your project.
+ - 2015/07/18 (1.44) - fixed angles in ImDrawList::PathArcTo(), PathArcToFast() (introduced in 1.43) being off by an extra PI for no justifiable reason
+ - 2015/07/14 (1.43) - add new ImFontAtlas::AddFont() API. For the old AddFont***, moved the 'font_no' parameter of ImFontAtlas::AddFont** functions to the ImFontConfig structure.
+                       you need to render your textured triangles with bilinear filtering to benefit from sub-pixel positioning of text.
+ - 2015/07/08 (1.43) - switched rendering data to use indexed rendering. this is saving a fair amount of CPU/GPU and enables us to get anti-aliasing for a marginal cost.
+                       this necessary change will break your rendering function! the fix should be very easy. sorry for that :(
+                     - if you are using a vanilla copy of one of the imgui_impl_XXXX.cpp provided in the example, you just need to update your copy and you can ignore the rest.
+                     - the signature of the io.RenderDrawListsFn handler has changed!
+                       old: ImGui_XXXX_RenderDrawLists(ImDrawList** const cmd_lists, int cmd_lists_count)
+                       new: ImGui_XXXX_RenderDrawLists(ImDrawData* draw_data).
+                         parameters: 'cmd_lists' becomes 'draw_data->CmdLists', 'cmd_lists_count' becomes 'draw_data->CmdListsCount'
+                         ImDrawList: 'commands' becomes 'CmdBuffer', 'vtx_buffer' becomes 'VtxBuffer', 'IdxBuffer' is new.
+                         ImDrawCmd:  'vtx_count' becomes 'ElemCount', 'clip_rect' becomes 'ClipRect', 'user_callback' becomes 'UserCallback', 'texture_id' becomes 'TextureId'.
+                     - each ImDrawList now contains both a vertex buffer and an index buffer. For each command, render ElemCount/3 triangles using indices from the index buffer.
+                     - if you REALLY cannot render indexed primitives, you can call the draw_data->DeIndexAllBuffers() method to de-index the buffers. This is slow and a waste of CPU/GPU. Prefer using indexed rendering!
+                     - refer to code in the examples/ folder or ask on the GitHub if you are unsure of how to upgrade. please upgrade!
+ - 2015/07/10 (1.43) - changed SameLine() parameters from int to float.
+ - 2015/07/02 (1.42) - renamed SetScrollPosHere() to SetScrollFromCursorPos(). Kept inline redirection function (will obsolete).
+ - 2015/07/02 (1.42) - renamed GetScrollPosY() to GetScrollY(). Necessary to reduce confusion along with other scrolling functions, because positions (e.g. cursor position) are not equivalent to scrolling amount.
+ - 2015/06/14 (1.41) - changed ImageButton() default bg_col parameter from (0,0,0,1) (black) to (0,0,0,0) (transparent) - makes a difference when texture have transparence
+ - 2015/06/14 (1.41) - changed Selectable() API from (label, selected, size) to (label, selected, flags, size). Size override should have been rarely be used. Sorry!
+ - 2015/05/31 (1.40) - renamed GetWindowCollapsed() to IsWindowCollapsed() for consistency. Kept inline redirection function (will obsolete).
+ - 2015/05/31 (1.40) - renamed IsRectClipped() to IsRectVisible() for consistency. Note that return value is opposite! Kept inline redirection function (will obsolete).
+ - 2015/05/27 (1.40) - removed the third 'repeat_if_held' parameter from Button() - sorry! it was rarely used and inconsistent. Use PushButtonRepeat(true) / PopButtonRepeat() to enable repeat on desired buttons.
+ - 2015/05/11 (1.40) - changed BeginPopup() API, takes a string identifier instead of a bool. ImGui needs to manage the open/closed state of popups. Call OpenPopup() to actually set the "open" state of a popup. BeginPopup() returns true if the popup is opened.
+ - 2015/05/03 (1.40) - removed style.AutoFitPadding, using style.WindowPadding makes more sense (the default values were already the same).
+ - 2015/04/13 (1.38) - renamed IsClipped() to IsRectClipped(). Kept inline redirection function until 1.50.
+ - 2015/04/09 (1.38) - renamed ImDrawList::AddArc() to ImDrawList::AddArcFast() for compatibility with future API
+ - 2015/04/03 (1.38) - removed ImGuiCol_CheckHovered, ImGuiCol_CheckActive, replaced with the more general ImGuiCol_FrameBgHovered, ImGuiCol_FrameBgActive.
+ - 2014/04/03 (1.38) - removed support for passing -FLT_MAX..+FLT_MAX as the range for a SliderFloat(). Use DragFloat() or Inputfloat() instead.
+ - 2015/03/17 (1.36) - renamed GetItemBoxMin()/GetItemBoxMax()/IsMouseHoveringBox() to GetItemRectMin()/GetItemRectMax()/IsMouseHoveringRect(). Kept inline redirection function until 1.50.
+ - 2015/03/15 (1.36) - renamed style.TreeNodeSpacing to style.IndentSpacing, ImGuiStyleVar_TreeNodeSpacing to ImGuiStyleVar_IndentSpacing
+ - 2015/03/13 (1.36) - renamed GetWindowIsFocused() to IsWindowFocused(). Kept inline redirection function until 1.50.
+ - 2015/03/08 (1.35) - renamed style.ScrollBarWidth to style.ScrollbarWidth (casing)
+ - 2015/02/27 (1.34) - renamed OpenNextNode(bool) to SetNextTreeNodeOpened(bool, ImGuiSetCond). Kept inline redirection function until 1.50.
+ - 2015/02/27 (1.34) - renamed ImGuiSetCondition_*** to ImGuiSetCond_***, and _FirstUseThisSession becomes _Once.
+ - 2015/02/11 (1.32) - changed text input callback ImGuiTextEditCallback return type from void-->int. reserved for future use, return 0 for now.
+ - 2015/02/10 (1.32) - renamed GetItemWidth() to CalcItemWidth() to clarify its evolving behavior

+
+ Q&A: Usage
+ ----------
+
+ Q: Why are multiple widgets reacting when I interact with a single one?
+ Q: How can I have multiple widgets with the same label or with an empty label?
+ A: A primer on labels and the ID Stack...
+
+    Dear ImGui internally need to uniquely identify UI elements.
+    Elements that are typically not clickable (such as calls to the Text functions) don't need an ID.
+    Interactive widgets (such as calls to Button buttons) need a unique ID.
+    Unique ID are used internally to track active widgets and occasionally associate state to widgets.
+    Unique ID are implicitly built from the hash of multiple elements that identify the "path" to the UI element.
+
+   - Unique ID are often derived from a string label:
+
+       Button("OK");          // Label = "OK",     ID = hash of (..., "OK")
+       Button("Cancel");      // Label = "Cancel", ID = hash of (..., "Cancel")
+
+   - ID are uniquely scoped within windows, tree nodes, etc. which all pushes to the ID stack. Having
+     two buttons labeled "OK" in different windows or different tree locations is fine.
+     We used "..." above to signify whatever was already pushed to the ID stack previously:
+
+       Begin("MyWindow");
+       Button("OK");          // Label = "OK",     ID = hash of ("MyWindow", "OK")
+       End();
+       Begin("MyOtherWindow");
+       Button("OK");          // Label = "OK",     ID = hash of ("MyOtherWindow", "OK")
+       End();
+
+   - If you have a same ID twice in the same location, you'll have a conflict:
+
+       Button("OK");
+       Button("OK");          // ID collision! Interacting with either button will trigger the first one.
+
+     Fear not! this is easy to solve and there are many ways to solve it!
+
+   - Solving ID conflict in a simple/local context:
+     When passing a label you can optionally specify extra ID information within string itself.
+     Use "##" to pass a complement to the ID that won't be visible to the end-user.
+     This helps solving the simple collision cases when you know e.g. at compilation time which items
+     are going to be created:
+
+       Begin("MyWindow");
+       Button("Play");        // Label = "Play",   ID = hash of ("MyWindow", "Play")
+       Button("Play##foo1");  // Label = "Play",   ID = hash of ("MyWindow", "Play##foo1")  // Different from above
+       Button("Play##foo2");  // Label = "Play",   ID = hash of ("MyWindow", "Play##foo2")  // Different from above
+       End();
+
+   - If you want to completely hide the label, but still need an ID:
+
+       Checkbox("##On", &b);  // Label = "",       ID = hash of (..., "##On")   // No visible label, just a checkbox!
+
+   - Occasionally/rarely you might want change a label while preserving a constant ID. This allows
+     you to animate labels. For example you may want to include varying information in a window title bar,
+     but windows are uniquely identified by their ID. Use "###" to pass a label that isn't part of ID:
+
+       Button("Hello###ID");  // Label = "Hello",  ID = hash of (..., "###ID")
+       Button("World###ID");  // Label = "World",  ID = hash of (..., "###ID")  // Same as above, even though the label looks different
+
+       sprintf(buf, "My game (%f FPS)###MyGame", fps);
+       Begin(buf);            // Variable title,   ID = hash of "MyGame"
+
+   - Solving ID conflict in a more general manner:
+     Use PushID() / PopID() to create scopes and manipulate the ID stack, as to avoid ID conflicts
+     within the same window. This is the most convenient way of distinguishing ID when iterating and
+     creating many UI elements programmatically.
+     You can push a pointer, a string or an integer value into the ID stack.
+     Remember that ID are formed from the concatenation of _everything_ pushed into the ID stack.
+     At each level of the stack we store the seed used for items at this level of the ID stack.
+
+     Begin("Window");
+       for (int i = 0; i < 100; i++)
+       {
+         PushID(i);           // Push i to the id tack
+         Button("Click");     // Label = "Click",  ID = hash of ("Window", i, "Click")
+         PopID();
+       }
+       for (int i = 0; i < 100; i++)
+       {
+         MyObject* obj = Objects[i];
+         PushID(obj);
+         Button("Click");     // Label = "Click",  ID = hash of ("Window", obj pointer, "Click")
+         PopID();
+       }
+       for (int i = 0; i < 100; i++)
+       {
+         MyObject* obj = Objects[i];
+         PushID(obj->Name);
+         Button("Click");     // Label = "Click",  ID = hash of ("Window", obj->Name, "Click")
+         PopID();
+       }
+       End();
+
+   - You can stack multiple prefixes into the ID stack:
+
+       Button("Click");       // Label = "Click",  ID = hash of (..., "Click")
+       PushID("node");
+       Button("Click");       // Label = "Click",  ID = hash of (..., "node", "Click")
+         PushID(my_ptr);
+           Button("Click");   // Label = "Click",  ID = hash of (..., "node", my_ptr, "Click")
+         PopID();
+       PopID();
+
+   - Tree nodes implicitly creates a scope for you by calling PushID().
+
+       Button("Click");       // Label = "Click",  ID = hash of (..., "Click")
+       if (TreeNode("node"))  // <-- this function call will do a PushID() for you (unless instructed not to, with a special flag)
+       {
+         Button("Click");     // Label = "Click",  ID = hash of (..., "node", "Click")
+         TreePop();
+       }
+
+   - When working with trees, ID are used to preserve the open/close state of each tree node.
+     Depending on your use cases you may want to use strings, indices or pointers as ID.
+      e.g. when following a single pointer that may change over time, using a static string as ID
+       will preserve your node open/closed state when the targeted object change.
+      e.g. when displaying a list of objects, using indices or pointers as ID will preserve the
+       node open/closed state differently. See what makes more sense in your situation!

+// - Step 1: the clipper infer height from first element, calculate the actual range of elements to display, and position the cursor before the first element.
+// - (Step 2: dummy step only required if an explicit items_height was passed to constructor or Begin() and user call Step(). Does nothing and switch to Step 3.)

+// It is the user-code responsibility to setup/build the atlas, then upload the pixel data into a texture accessible by your graphics api.
+//  - Optionally, call any of the AddFont*** functions. If you don't call any, the default font embedded in the code will be loaded for you.
+//  - Call GetTexDataAsAlpha8() or GetTexDataAsRGBA32() to build and retrieve pixels data.
+//  - Upload the pixels data into a texture within your graphics system (see imgui_impl_xxxx.cpp examples)

+// Common pitfalls:
+// - If you pass a 'glyph_ranges' array to AddFont*** functions, you need to make sure that your array persist up until the
+//   atlas is build (when calling GetTexData*** or Build()). We only copy the pointer, not the data.
+// - Important: By default, AddFontFromMemoryTTF() takes ownership of the data. Even though we are not writing to it, we will free the pointer on destruction.
+//   You can set font_cfg->FontDataOwnedByAtlas=false to keep ownership of your data and it won't be freed,
+// - Even though many functions are suffixed with "TTF", OTF data is supported just as well.
+// - This is an old API and it is currently awkward for those and and various other reasons! We will address them in the future!

+// dear imgui, v1.76 WIP
+// (demo code)
+
+// Help:
+// - Read FAQ at http://dearimgui.org/faq
+// - Newcomers, read 'Programmer guide' in imgui.cpp for notes on how to setup Dear ImGui in your codebase.
+// - Call and read ImGui::ShowDemoWindow() in imgui_demo.cpp for demo code. All applications in examples/ are doing that.
+// Read imgui.cpp for more details, documentation and comments.
+// Get latest version at https://github.com/ocornut/imgui
+
+// Message to the person tempted to delete this file when integrating Dear ImGui into their code base:
+// Do NOT remove this file from your project! Think again! It is the most useful reference code that you and other coders
+// will want to refer to and call. Have the ImGui::ShowDemoWindow() function wired in an always-available debug menu of
+// your game/app! Removing this file from your project is hindering access to documentation for everyone in your team,
+// likely leading you to poorer usage of the library.
+// Everything in this file will be stripped out by the linker if you don't call ImGui::ShowDemoWindow().
+// If you want to link core Dear ImGui in your shipped builds but want a thorough guarantee that the demo will not be linked,
+// you can setup your imconfig.h with #define IMGUI_DISABLE_DEMO_WINDOWS and those functions will be empty.
+// In other situation, whenever you have Dear ImGui available you probably want this to be available for reference.
+// Thank you,
+// -Your beloved friend, imgui_demo.cpp (which you won't delete)
+
+// Message to beginner C/C++ programmers about the meaning of the 'static' keyword:
+// In this demo code, we frequently we use 'static' variables inside functions. A static variable persist across calls, so it is
+// essentially like a global variable but declared inside the scope of the function. We do this as a way to gather code and data
+// in the same place, to make the demo source code faster to read, faster to write, and smaller in size.
+// It also happens to be a convenient way of storing simple UI related information as long as your function doesn't need to be
+// reentrant or used in multiple threads. This might be a pattern you will want to use in your code, but most of the real data
+// you would be editing is likely going to be stored outside your functions.
+
+// The Demo code in this file is designed to be easy to copy-and-paste in into your application!
+// Because of this:
+// - We never omit the ImGui:: namespace when calling functions, even though most of our code is already in the same namespace.
+// - We try to declare static variables in the local scope, as close as possible to the code using them.
+// - We never use any of the helpers/facilities used internally by Dear ImGui, unless it has been exposed in the public API (imgui.h).
+// - We never use maths operators on ImVec2/ImVec4. For other of our sources files, they are provided by imgui_internal.h w/ IMGUI_DEFINE_MATH_OPERATORS.
+//   For your own sources file they are optional and require you either enable those, either provide your own via IM_VEC2_CLASS_EXTRA in imconfig.h.
+//   Because we don't want to assume anything about your support of maths operators, we don't use them in imgui_demo.cpp.

+// dear imgui: Platform Binding for GLFW
+// This needs to be used along with a Renderer (e.g. OpenGL3, Vulkan..)
+// (Info: GLFW is a cross-platform general purpose library for handling windows, inputs, OpenGL/Vulkan graphics context creation, etc.)
+// (Requires: GLFW 3.1+)
+
+// Implemented features:
+//  [X] Platform: Clipboard support.
+//  [X] Platform: Gamepad support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
+//  [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange' (note: the resizing cursors requires GLFW 3.4+).
+//  [X] Platform: Keyboard arrays indexed using GLFW_KEY_* codes, e.g. ImGui::IsKeyPressed(GLFW_KEY_SPACE).
+
+// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
+// If you are new to dear imgui, read examples/README.txt and read the documentation at the top of imgui.cpp.
+// https://github.com/ocornut/imgui
+
+// CHANGELOG
+// (minor and older changes stripped away, please see git history for details)
+//  2020-01-17: Inputs: Disable error callback while assigning mouse cursors because some X11 setup don't have them and it generates errors.
+//  2019-12-05: Inputs: Added support for new mouse cursors added in GLFW 3.4+ (resizing cursors, not allowed cursor).
+//  2019-10-18: Misc: Previously installed user callbacks are now restored on shutdown.
+//  2019-07-21: Inputs: Added mapping for ImGuiKey_KeyPadEnter.
+//  2019-05-11: Inputs: Don't filter value from character callback before calling AddInputCharacter().
+//  2019-03-12: Misc: Preserve DisplayFramebufferScale when main window is minimized.
+//  2018-11-30: Misc: Setting up io.BackendPlatformName so it can be displayed in the About Window.
+//  2018-11-07: Inputs: When installing our GLFW callbacks, we save user's previously installed ones - if any - and chain call them.
+//  2018-08-01: Inputs: Workaround for Emscripten which doesn't seem to handle focus related calls.
+//  2018-06-29: Inputs: Added support for the ImGuiMouseCursor_Hand cursor.
+//  2018-06-08: Misc: Extracted imgui_impl_glfw.cpp/.h away from the old combined GLFW+OpenGL/Vulkan examples.
+//  2018-03-20: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors flag + honor ImGuiConfigFlags_NoMouseCursorChange flag.
+//  2018-02-20: Inputs: Added support for mouse cursors (ImGui::GetMouseCursor() value, passed to glfwSetCursor()).
+//  2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
+//  2018-02-06: Inputs: Added mapping for ImGuiKey_Space.
+//  2018-01-25: Inputs: Added gamepad support if ImGuiConfigFlags_NavEnableGamepad is set.
+//  2018-01-25: Inputs: Honoring the io.WantSetMousePos by repositioning the mouse (when using navigation and ImGuiConfigFlags_NavMoveMouse is set).
+//  2018-01-20: Inputs: Added Horizontal Mouse Wheel support.
+//  2018-01-18: Inputs: Added mapping for ImGuiKey_Insert.
+//  2017-08-25: Inputs: MousePos set to -FLT_MAX,-FLT_MAX when mouse is unavailable/missing (instead of -1,-1).
+//  2016-10-15: Misc: Added a void* user_data parameter to Clipboard function handlers.

+// CHANGELOG
+// (minor and older changes stripped away, please see git history for details)
+//  2020-01-07: OpenGL: Added support for glbindings OpenGL loader.
+//  2019-10-25: OpenGL: Using a combination of GL define and runtime GL version to decide whether to use glDrawElementsBaseVertex(). Fix building with pre-3.2 GL loaders.
+//  2019-09-22: OpenGL: Detect default GL loader using __has_include compiler facility.
+//  2019-09-16: OpenGL: Tweak initialization code to allow application calling ImGui_ImplOpenGL3_CreateFontsTexture() before the first NewFrame() call.
+//  2019-05-29: OpenGL: Desktop GL only: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
+//  2019-04-30: OpenGL: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
+//  2019-03-29: OpenGL: Not calling glBindBuffer more than necessary in the render loop.
+//  2019-03-15: OpenGL: Added a dummy GL call + comments in ImGui_ImplOpenGL3_Init() to detect uninitialized GL function loaders early.
+//  2019-03-03: OpenGL: Fix support for ES 2.0 (WebGL 1.0).
+//  2019-02-20: OpenGL: Fix for OSX not supporting OpenGL 4.5, we don't try to read GL_CLIP_ORIGIN even if defined by the headers/loader.
+//  2019-02-11: OpenGL: Projecting clipping rectangles correctly using draw_data->FramebufferScale to allow multi-viewports for retina display.
+//  2019-02-01: OpenGL: Using GLSL 410 shaders for any version over 410 (e.g. 430, 450).
+//  2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
+//  2018-11-13: OpenGL: Support for GL 4.5's glClipControl(GL_UPPER_LEFT) / GL_CLIP_ORIGIN.
+//  2018-08-29: OpenGL: Added support for more OpenGL loaders: glew and glad, with comments indicative that any loader can be used.
+//  2018-08-09: OpenGL: Default to OpenGL ES 3 on iOS and Android. GLSL version default to "#version 300 ES".
+//  2018-07-30: OpenGL: Support for GLSL 300 ES and 410 core. Fixes for Emscripten compilation.
+//  2018-07-10: OpenGL: Support for more GLSL versions (based on the GLSL version string). Added error output when shaders fail to compile/link.
+//  2018-06-08: Misc: Extracted imgui_impl_opengl3.cpp/.h away from the old combined GLFW/SDL+OpenGL3 examples.
+//  2018-06-08: OpenGL: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
+//  2018-05-25: OpenGL: Removed unnecessary backup/restore of GL_ELEMENT_ARRAY_BUFFER_BINDING since this is part of the VAO state.
+//  2018-05-14: OpenGL: Making the call to glBindSampler() optional so 3.2 context won't fail if the function is a NULL pointer.
+//  2018-03-06: OpenGL: Added const char* glsl_version parameter to ImGui_ImplOpenGL3_Init() so user can override the GLSL version e.g. "#version 150".
+//  2018-02-23: OpenGL: Create the VAO in the render function so the setup can more easily be used with multiple shared GL context.
+//  2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplSdlGL3_RenderDrawData() in the .h file so you can call it yourself.
+//  2018-01-07: OpenGL: Changed GLSL shader version from 330 to 150.
+//  2017-09-01: OpenGL: Save and restore current bound sampler. Save and restore current polygon mode.
+//  2017-05-01: OpenGL: Fixed save and restore of current blend func state.
+//  2017-05-01: OpenGL: Fixed save and restore of current GL_ACTIVE_TEXTURE.
+//  2016-09-05: OpenGL: Fixed save and restore of current scissor rectangle.
+//  2016-07-29: OpenGL: Explicitly setting GL_UNPACK_ROW_LENGTH to reduce issues because SDL changes it. (#752)

+// dear imgui: Renderer for modern OpenGL with shaders / programmatic pipeline
+// - Desktop GL: 2.x 3.x 4.x
+// - Embedded GL: ES 2.0 (WebGL 1.0), ES 3.0 (WebGL 2.0)
+// This needs to be used along with a Platform Binding (e.g. GLFW, SDL, Win32, custom..)
+
+// Implemented features:
+//  [X] Renderer: User texture binding. Use 'GLuint' OpenGL texture identifier as void*/ImTextureID. Read the FAQ about ImTextureID!
+//  [x] Renderer: Desktop GL only: Support for large meshes (64k+ vertices) with 16-bit indices.
+
+// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
+// If you are new to dear imgui, read examples/README.txt and read the documentation at the top of imgui.cpp.
+// https://github.com/ocornut/imgui
+
+// About Desktop OpenGL function loaders:
+//  Modern desktop OpenGL doesn't have a standard portable header file to load OpenGL function pointers.
+//  Helper libraries are often used for this purpose! Here we are supporting a few common ones (gl3w, glew, glad).
+//  You may use another loader/header of your choice (glext, glLoadGen, etc.), or chose to manually implement your own.
+
+// About GLSL version:
+//  The 'glsl_version' initialization parameter should be NULL (default) or a "#version XXX" string.
+//  On computer platform the GLSL version default to "#version 130". On OpenGL ES 3 platform it defaults to "#version 300 es"
+//  Only override if your GL version doesn't handle this GLSL version. See GLSL version table at the top of imgui_impl_opengl3.cpp.

+// stb_rect_pack.h - v1.00 - public domain - rectangle packing
+// Sean Barrett 2014
+//
+// Useful for e.g. packing rectangular textures into an atlas.
+// Does not do rotation.
+//
+// Not necessarily the awesomest packing method, but better than
+// the totally naive one in stb_truetype (which is primarily what
+// this is meant to replace).
+//
+// Has only had a few tests run, may have issues.
+//
+// More docs to come.
+//
+// No memory allocations; uses qsort() and assert() from stdlib.
+// Can override those by defining STBRP_SORT and STBRP_ASSERT.
+//
+// This library currently uses the Skyline Bottom-Left algorithm.
+//
+// Please note: better rectangle packers are welcome! Please
+// implement them to the same API, but with a different init
+// function.

+// [DEAR IMGUI]
+// This is a slightly modified version of stb_textedit.h 1.13. 
+// Those changes would need to be pushed into nothings/stb:
+// - Fix in stb_textedit_discard_redo (see https://github.com/nothings/stb/issues/321)
+// Grep for [DEAR IMGUI] to find the changes.
+
+// stb_textedit.h - v1.13  - public domain - Sean Barrett
+// Development of this library was sponsored by RAD Game Tools
+//
+// This C header file implements the guts of a multi-line text-editing
+// widget; you implement display, word-wrapping, and low-level string
+// insertion/deletion, and stb_textedit will map user inputs into
+// insertions & deletions, plus updates to the cursor position,
+// selection state, and undo state.
+//
+// It is intended for use in games and other systems that need to build
+// their own custom widgets and which do not have heavy text-editing
+// requirements (this library is not recommended for use for editing large
+// texts, as its performance does not scale and it has limited undo).
+//
+// Non-trivial behaviors are modelled after Windows text controls.
+// 
+//
+// LICENSE
+//
+// See end of file for license information.
+//
+//
+// DEPENDENCIES
+//
+// Uses the C runtime function 'memmove', which you can override
+// by defining STB_TEXTEDIT_memmove before the implementation.
+// Uses no other functions. Performs no runtime allocations.
+//

+// USAGE
+//
+// This file behaves differently depending on what symbols you define
+// before including it.
+//
+//
+// Header-file mode:
+//
+//   If you do not define STB_TEXTEDIT_IMPLEMENTATION before including this,
+//   it will operate in "header file" mode. In this mode, it declares a
+//   single public symbol, STB_TexteditState, which encapsulates the current
+//   state of a text widget (except for the string, which you will store
+//   separately).
+//
+//   To compile in this mode, you must define STB_TEXTEDIT_CHARTYPE to a
+//   primitive type that defines a single character (e.g. char, wchar_t, etc).
+//
+//   To save space or increase undo-ability, you can optionally define the
+//   following things that are used by the undo system:
+//
+//      STB_TEXTEDIT_POSITIONTYPE         small int type encoding a valid cursor position
+//      STB_TEXTEDIT_UNDOSTATECOUNT       the number of undo states to allow
+//      STB_TEXTEDIT_UNDOCHARCOUNT        the number of characters to store in the undo buffer
+//
+//   If you don't define these, they are set to permissive types and
+//   moderate sizes. The undo system does no memory allocations, so
+//   it grows STB_TexteditState by the worst-case storage which is (in bytes):
+//
+//        [4 + 3 * sizeof(STB_TEXTEDIT_POSITIONTYPE)] * STB_TEXTEDIT_UNDOSTATE_COUNT
+//      +          sizeof(STB_TEXTEDIT_CHARTYPE)      * STB_TEXTEDIT_UNDOCHAR_COUNT
+//
+//
+// Implementation mode:
+//
+//   If you define STB_TEXTEDIT_IMPLEMENTATION before including this, it
+//   will compile the implementation of the text edit widget, depending
+//   on a large number of symbols which must be defined before the include.
+//
+//   The implementation is defined only as static functions. You will then
+//   need to provide your own APIs in the same file which will access the
+//   static functions.
+//
+//   The basic concept is that you provide a "string" object which
+//   behaves like an array of characters. stb_textedit uses indices to
+//   refer to positions in the string, implicitly representing positions
+//   in the displayed textedit. This is true for both plain text and
+//   rich text; even with rich text stb_truetype interacts with your
+//   code as if there was an array of all the displayed characters.
+//
+// Symbols that must be the same in header-file and implementation mode:
+//
+//     STB_TEXTEDIT_CHARTYPE             the character type
+//     STB_TEXTEDIT_POSITIONTYPE         small type that is a valid cursor position
+//     STB_TEXTEDIT_UNDOSTATECOUNT       the number of undo states to allow
+//     STB_TEXTEDIT_UNDOCHARCOUNT        the number of characters to store in the undo buffer
+//
+// Symbols you must define for implementation mode:
+//
+//    STB_TEXTEDIT_STRING               the type of object representing a string being edited,
+//                                      typically this is a wrapper object with other data you need
+//
+//    STB_TEXTEDIT_STRINGLEN(obj)       the length of the string (ideally O(1))
+//    STB_TEXTEDIT_LAYOUTROW(&r,obj,n)  returns the results of laying out a line of characters
+//                                        starting from character #n (see discussion below)
+//    STB_TEXTEDIT_GETWIDTH(obj,n,i)    returns the pixel delta from the xpos of the i'th character
+//                                        to the xpos of the i+1'th char for a line of characters
+//                                        starting at character #n (i.e. accounts for kerning
+//                                        with previous char)
+//    STB_TEXTEDIT_KEYTOTEXT(k)         maps a keyboard input to an insertable character
+//                                        (return type is int, -1 means not valid to insert)
+//    STB_TEXTEDIT_GETCHAR(obj,i)       returns the i'th character of obj, 0-based
+//    STB_TEXTEDIT_NEWLINE              the character returned by _GETCHAR() we recognize
+//                                        as manually wordwrapping for end-of-line positioning
+//
+//    STB_TEXTEDIT_DELETECHARS(obj,i,n)      delete n characters starting at i
+//    STB_TEXTEDIT_INSERTCHARS(obj,i,c*,n)   insert n characters at i (pointed to by STB_TEXTEDIT_CHARTYPE*)
+//
+//    STB_TEXTEDIT_K_SHIFT       a power of two that is or'd in to a keyboard input to represent the shift key
+//
+//    STB_TEXTEDIT_K_LEFT        keyboard input to move cursor left
+//    STB_TEXTEDIT_K_RIGHT       keyboard input to move cursor right
+//    STB_TEXTEDIT_K_UP          keyboard input to move cursor up
+//    STB_TEXTEDIT_K_DOWN        keyboard input to move cursor down
+//    STB_TEXTEDIT_K_LINESTART   keyboard input to move cursor to start of line  // e.g. HOME
+//    STB_TEXTEDIT_K_LINEEND     keyboard input to move cursor to end of line    // e.g. END
+//    STB_TEXTEDIT_K_TEXTSTART   keyboard input to move cursor to start of text  // e.g. ctrl-HOME
+//    STB_TEXTEDIT_K_TEXTEND     keyboard input to move cursor to end of text    // e.g. ctrl-END
+//    STB_TEXTEDIT_K_DELETE      keyboard input to delete selection or character under cursor
+//    STB_TEXTEDIT_K_BACKSPACE   keyboard input to delete selection or character left of cursor
+//    STB_TEXTEDIT_K_UNDO        keyboard input to perform undo
+//    STB_TEXTEDIT_K_REDO        keyboard input to perform redo
+//
+// Optional:
+//    STB_TEXTEDIT_K_INSERT              keyboard input to toggle insert mode
+//    STB_TEXTEDIT_IS_SPACE(ch)          true if character is whitespace (e.g. 'isspace'),
+//                                          required for default WORDLEFT/WORDRIGHT handlers
+//    STB_TEXTEDIT_MOVEWORDLEFT(obj,i)   custom handler for WORDLEFT, returns index to move cursor to
+//    STB_TEXTEDIT_MOVEWORDRIGHT(obj,i)  custom handler for WORDRIGHT, returns index to move cursor to
+//    STB_TEXTEDIT_K_WORDLEFT            keyboard input to move cursor left one word // e.g. ctrl-LEFT
+//    STB_TEXTEDIT_K_WORDRIGHT           keyboard input to move cursor right one word // e.g. ctrl-RIGHT
+//    STB_TEXTEDIT_K_LINESTART2          secondary keyboard input to move cursor to start of line
+//    STB_TEXTEDIT_K_LINEEND2            secondary keyboard input to move cursor to end of line
+//    STB_TEXTEDIT_K_TEXTSTART2          secondary keyboard input to move cursor to start of text
+//    STB_TEXTEDIT_K_TEXTEND2            secondary keyboard input to move cursor to end of text
+//
+// Todo:
+//    STB_TEXTEDIT_K_PGUP        keyboard input to move cursor up a page
+//    STB_TEXTEDIT_K_PGDOWN      keyboard input to move cursor down a page
+//
+// Keyboard input must be encoded as a single integer value; e.g. a character code
+// and some bitflags that represent shift states. to simplify the interface, SHIFT must
+// be a bitflag, so we can test the shifted state of cursor movements to allow selection,
+// i.e. (STB_TEXTED_K_RIGHT|STB_TEXTEDIT_K_SHIFT) should be shifted right-arrow.
+//
+// You can encode other things, such as CONTROL or ALT, in additional bits, and
+// then test for their presence in e.g. STB_TEXTEDIT_K_WORDLEFT. For example,
+// my Windows implementations add an additional CONTROL bit, and an additional KEYDOWN
+// bit. Then all of the STB_TEXTEDIT_K_ values bitwise-or in the KEYDOWN bit,
+// and I pass both WM_KEYDOWN and WM_CHAR events to the "key" function in the
+// API below. The control keys will only match WM_KEYDOWN events because of the
+// keydown bit I add, and STB_TEXTEDIT_KEYTOTEXT only tests for the KEYDOWN
+// bit so it only decodes WM_CHAR events.
+//
+// STB_TEXTEDIT_LAYOUTROW returns information about the shape of one displayed
+// row of characters assuming they start on the i'th character--the width and
+// the height and the number of characters consumed. This allows this library
+// to traverse the entire layout incrementally. You need to compute word-wrapping
+// here.
+//
+// Each textfield keeps its own insert mode state, which is not how normal
+// applications work. To keep an app-wide insert mode, update/copy the
+// "insert_mode" field of STB_TexteditState before/after calling API functions.
+//
+// API
+//
+//    void stb_textedit_initialize_state(STB_TexteditState *state, int is_single_line)
+//
+//    void stb_textedit_click(STB_TEXTEDIT_STRING *str, STB_TexteditState *state, float x, float y)
+//    void stb_textedit_drag(STB_TEXTEDIT_STRING *str, STB_TexteditState *state, float x, float y)

+//
+//      initialize_state:
+//          set the textedit state to a known good default state when initially
+//          constructing the textedit.
+//
+//      click:
+//          call this with the mouse x,y on a mouse down; it will update the cursor
+//          and reset the selection start/end to the cursor point. the x,y must
+//          be relative to the text widget, with (0,0) being the top left.
+//     
+//      drag:
+//          call this with the mouse x,y on a mouse drag/up; it will update the
+//          cursor and the selection end point
+//     
+//      cut:
+//          call this to delete the current selection; returns true if there was
+//          one. you should FIRST copy the current selection to the system paste buffer.
+//          (To copy, just copy the current selection out of the string yourself.)
+//     
+//      paste:
+//          call this to paste text at the current cursor point or over the current
+//          selection if there is one.
+//     
+//      key:
+//          call this for keyboard inputs sent to the textfield. you can use it
+//          for "key down" events or for "translated" key events. if you need to
+//          do both (as in Win32), or distinguish Unicode characters from control
+//          inputs, set a high bit to distinguish the two; then you can define the
+//          various definitions like STB_TEXTEDIT_K_LEFT have the is-key-event bit
+//          set, and make STB_TEXTEDIT_KEYTOCHAR check that the is-key-event bit is
+//          clear. STB_TEXTEDIT_KEYTYPE defaults to int, but you can #define it to
+//          anything other type you wante before including.
+//
+//     
+//   When rendering, you can read the cursor position and selection state from
+//   the STB_TexteditState.
+//
+//
+// Notes:
+//
+// This is designed to be usable in IMGUI, so it allows for the possibility of
+// running in an IMGUI that has NOT cached the multi-line layout. For this
+// reason, it provides an interface that is compatible with computing the
+// layout incrementally--we try to make sure we make as few passes through
+// as possible. (For example, to locate the mouse pointer in the text, we
+// could define functions that return the X and Y positions of characters
+// and binary search Y and then X, but if we're doing dynamic layout this
+// will run the layout algorithm many times, so instead we manually search
+// forward in one pass. Similar logic applies to e.g. up-arrow and
+// down-arrow movement.)
+//
+// If it's run in a widget that *has* cached the layout, then this is less
+// efficient, but it's not horrible on modern computers. But you wouldn't
+// want to edit million-line files with it.

+//   Starting with version 1.06, the rasterizer was replaced with a new,
+//   faster and generally-more-precise rasterizer. The new rasterizer more
+//   accurately measures pixel coverage for anti-aliasing, except in the case
+//   where multiple shapes overlap, in which case it overestimates the AA pixel
+//   coverage. Thus, anti-aliasing of intersecting shapes may look wrong. If
+//   this turns out to be a problem, you can re-enable the old rasterizer with
+//        #define STBTT_RASTERIZER_VERSION 1
+//   which will incur about a 15% speed hit.
+//
+// ADDITIONAL DOCUMENTATION
+//
+//   Immediately after this block comment are a series of sample programs.
+//
+//   After the sample programs is the "header file" section. This section
+//   includes documentation for each API function.
+//
+//   Some important concepts to understand to use this library:
+//
+//      Codepoint
+//         Characters are defined by unicode codepoints, e.g. 65 is
+//         uppercase A, 231 is lowercase c with a cedilla, 0x7e30 is
+//         the hiragana for "ma".
+//
+//      Glyph
+//         A visual character shape (every codepoint is rendered as
+//         some glyph)
+//
+//      Glyph index
+//         A font-specific integer ID representing a glyph
+//
+//      Baseline
+//         Glyph shapes are defined relative to a baseline, which is the
+//         bottom of uppercase characters. Characters extend both above
+//         and below the baseline.
+//
+//      Current Point
+//         As you draw text to the screen, you keep track of a "current point"
+//         which is the origin of each character. The current point's vertical
+//         position is the baseline. Even "baked fonts" use this model.
+//
+//      Vertical Font Metrics
+//         The vertical qualities of the font, used to vertically position
+//         and space the characters. See docs for stbtt_GetFontVMetrics.
+//
+//      Font Size in Pixels or Points
+//         The preferred interface for specifying font sizes in stb_truetype
+//         is to specify how tall the font's vertical extent should be in pixels.
+//         If that sounds good enough, skip the next paragraph.
+//
+//         Most font APIs instead use "points", which are a common typographic
+//         measurement for describing font size, defined as 72 points per inch.
+//         stb_truetype provides a point API for compatibility. However, true
+//         "per inch" conventions don't make much sense on computer displays
+//         since different monitors have different number of pixels per
+//         inch. For example, Windows traditionally uses a convention that
+//         there are 96 pixels per inch, thus making 'inch' measurements have
+//         nothing to do with inches, and thus effectively defining a point to
+//         be 1.333 pixels. Additionally, the TrueType font data provides
+//         an explicit scale factor to scale a given font's glyphs to points,
+//         but the author has observed that this scale factor is often wrong
+//         for non-commercial fonts, thus making fonts scaled in points
+//         according to the TrueType spec incoherently sized in practice.
+//
+// DETAILED USAGE:
+//
+//  Scale:
+//    Select how high you want the font to be, in points or pixels.
+//    Call ScaleForPixelHeight or ScaleForMappingEmToPixels to compute
+//    a scale factor SF that will be used by all other functions.
+//
+//  Baseline:
+//    You need to select a y-coordinate that is the baseline of where
+//    your text will appear. Call GetFontBoundingBox to get the baseline-relative
+//    bounding box for all characters. SF*-y0 will be the distance in pixels
+//    that the worst-case character could extend above the baseline, so if
+//    you want the top edge of characters to appear at the top of the
+//    screen where y=0, then you would set the baseline to SF*-y0.
+//
+//  Current point:
+//    Set the current point where the first character will appear. The
+//    first character could extend left of the current point; this is font
+//    dependent. You can either choose a current point that is the leftmost
+//    point and hope, or add some padding, or check the bounding box or
+//    left-side-bearing of the first character to be displayed and set
+//    the current point based on that.
+//
+//  Displaying a character:
+//    Compute the bounding box of the character. It will contain signed values
+//    relative to <current_point, baseline>. I.e. if it returns x0,y0,x1,y1,
+//    then the character should be displayed in the rectangle from
+//    <current_point+SF*x0, baseline+SF*y0> to <current_point+SF*x1,baseline+SF*y1).
+//
+//  Advancing for the next character:
+//    Call GlyphHMetrics, and compute 'current_point += SF * advance'.
+// 
+//
+// ADVANCED USAGE
+//
+//   Quality:
+//
+//    - Use the functions with Subpixel at the end to allow your characters
+//      to have subpixel positioning. Since the font is anti-aliased, not
+//      hinted, this is very import for quality. (This is not possible with
+//      baked fonts.)
+//
+//    - Kerning is now supported, and if you're supporting subpixel rendering
+//      then kerning is worth using to give your text a polished look.
+//
+//   Performance:
+//
+//    - Convert Unicode codepoints to glyph indexes and operate on the glyphs;
+//      if you don't do this, stb_truetype is forced to do the conversion on
+//      every call.
+//
+//    - There are a lot of memory allocations. We should modify it to take
+//      a temp buffer and allocate from the temp buffer (without freeing),
+//      should help performance a lot.
+//
+// NOTES
+//
+//   The system uses the raw data found in the .ttf file without changing it
+//   and without building auxiliary data structures. This is a bit inefficient
+//   on little-endian systems (the data is big-endian), but assuming you're
+//   caching the bitmaps or glyph shapes this shouldn't be a big deal.
+//
+//   It appears to be very hard to programmatically determine what font a
+//   given file is in a general way. I provide an API for this, but I don't
+//   recommend it.

+//                                 if positive, > onedge_value is inside; if negative, < onedge_value is inside
+//        width,height      --  output height & width of the SDF bitmap (including padding)
+//        xoff,yoff         --  output origin of the character
+//        return value      --  a 2D array of bytes 0..255, width*height in size
+//
+// pixel_dist_scale & onedge_value are a scale & bias that allows you to make
+// optimal use of the limited 0..255 for your application, trading off precision
+// and special effects. SDF values outside the range 0..255 are clamped to 0..255.
+//
+// Example:
+//      scale = stbtt_ScaleForPixelHeight(22)
+//      padding = 5
+//      onedge_value = 180
+//      pixel_dist_scale = 180/5.0 = 36.0
+//
+//      This will create an SDF bitmap in which the character is about 22 pixels
+//      high but the whole bitmap is about 22+5+5=32 pixels high. To produce a filled
+//      shape, sample the SDF at each pixel and fill the pixel if the SDF value
+//      is greater than or equal to 180/255. (You'll actually want to antialias,
+//      which is beyond the scope of this example.) Additionally, you can compute
+//      offset outlines (e.g. to stroke the character border inside & outside,
+//      or only outside). For example, to fill outside the character up to 3 SDF
+//      pixels, you would compare against (180-36.0*3)/255 = 72/255. The above
+//      choice of variables maps a range from 5 pixels outside the shape to
+//      2 pixels inside the shape to 0..255; this is intended primarily for apply
+//      outside effects only (the interior range is needed to allow proper
+//      antialiasing of the font at *smaller* sizes)
+//
+// The function computes the SDF analytically at each SDF pixel, not by e.g.
+// building a higher-res bitmap and approximating it. In theory the quality
+// should be as high as possible for an SDF of this size & representation, but
+// unclear if this is true in practice (perhaps building a higher-res bitmap
+// and computing from that can allow drop-out prevention).
+//
+// The algorithm has not been optimized at all, so expect it to be slow
+// if computing lots of characters or very large sizes.

+// Finding the right font...
+//
+// You should really just solve this offline, keep your own tables
+// of what font is what, and don't try to get it out of the .ttf file.
+// That's because getting it out of the .ttf file is really hard, because
+// the names in the file can appear in many possible encodings, in many
+// possible languages, and e.g. if you need a case-insensitive comparison,
+// the details of that depend on the encoding & language in a complex way
+// (actually underspecified in truetype, but also gigantic).
+//
+// But you can use the provided functions in two possible ways:
+//     stbtt_FindMatchingFont() will use *case-sensitive* comparisons on
+//             unicode-encoded names to try to find the font you want;
+//             you can run this before calling stbtt_InitFont()
+//
+//     stbtt_GetFontNameString() lets you get any of the various strings
+//             from the file yourself and do your own comparisons on them.
+//             You have to have called stbtt_InitFont() first.
+
+
+STBTT_DEF int stbtt_FindMatchingFont(const unsigned char *fontdata, const char *name, int flags);
+// returns the offset (not index) of the font that matches, or -1 if none
+//   if you use STBTT_MACSTYLE_DONTCARE, use a font name like "Arial Bold".
+//   if you use any other flag, use a font name like "Arial"; this checks
+//     the 'macStyle' header field; i don't know if fonts set this consistently

+ * by Khronos client API header files that use its types and defines.
+ *
+ * The types in khrplatform.h should only be used to define API-specific types.
+ *
+ * Types defined in khrplatform.h:
+ *    khronos_int8_t              signed   8  bit
+ *    khronos_uint8_t             unsigned 8  bit
+ *    khronos_int16_t             signed   16 bit
+ *    khronos_uint16_t            unsigned 16 bit
+ *    khronos_int32_t             signed   32 bit
+ *    khronos_uint32_t            unsigned 32 bit
+ *    khronos_int64_t             signed   64 bit
+ *    khronos_uint64_t            unsigned 64 bit
+ *    khronos_intptr_t            signed   same number of bits as a pointer
+ *    khronos_uintptr_t           unsigned same number of bits as a pointer
+ *    khronos_ssize_t             signed   size
+ *    khronos_usize_t             unsigned size
+ *    khronos_float_t             signed   32 bit floating point
+ *    khronos_time_ns_t           unsigned 64 bit time in nanoseconds
+ *    khronos_utime_nanoseconds_t unsigned time interval or absolute time in
+ *                                         nanoseconds
+ *    khronos_stime_nanoseconds_t signed time interval in nanoseconds
+ *    khronos_boolean_enum_t      enumerated boolean type. This should
+ *      only be used as a base type when a client API's boolean type is
+ *      an enum. Client APIs which use an integer or other type for
+ *      booleans cannot use this as the base type for their boolean.
+ *
+ * Tokens defined in khrplatform.h:
+ *
+ *    KHRONOS_FALSE, KHRONOS_TRUE Enumerated boolean false/true values.
+ *
+ *    KHRONOS_SUPPORT_INT64 is 1 if 64 bit integers are supported; otherwise 0.
+ *    KHRONOS_SUPPORT_FLOAT is 1 if floats are supported; otherwise 0.
+ *
+ * Calling convention macros defined in this file:
+ *    KHRONOS_APICALL
+ *    KHRONOS_APIENTRY
+ *    KHRONOS_APIATTRIBUTES

+## Introduction
+
+GLFW is an Open Source, multi-platform library for OpenGL, OpenGL ES and Vulkan
+application development.  It provides a simple, platform-independent API for
+creating windows, contexts and surfaces, reading input, handling events, etc.
+
+GLFW natively supports Windows, macOS and Linux and other Unix-like systems.  On
+Linux both X11 and Wayland are supported.
+
+GLFW is licensed under the [zlib/libpng
+license](http://www.glfw.org/license.html).
+
+You can [download](http://www.glfw.org/download.html) the latest stable release
+as source or Windows binaries, or fetch the `latest` branch from GitHub.  Each
+release starting with 3.0 also has a corresponding [annotated
+tag](https://github.com/glfw/glfw/releases) with source and binary archives.
+
+The [documentation](http://www.glfw.org/docs/latest/) is available online and is
+included in all source and binary archives.  See the [release
+notes](https://www.glfw.org/docs/latest/news.html) for new features, caveats and
+deprecations in the latest release.  For more details see the [version
+history](http://www.glfw.org/changelog.html).
+
+The `master` branch is the stable integration branch and _should_ always compile
+and run on all supported platforms, although details of newly added features may
+change until they have been included in a release.  New features and many bug
+fixes live in [other branches](https://github.com/glfw/glfw/branches/all) until
+they are stable enough to merge.
+
+If you are new to GLFW, you may find the
+[tutorial](http://www.glfw.org/docs/latest/quick.html) for GLFW 3 useful.  If
+you have used GLFW 2 in the past, there is a [transition
+guide](http://www.glfw.org/docs/latest/moving.html) for moving to the GLFW
+3 API.
+
+
+## Compiling GLFW
+
+GLFW itself requires only the headers and libraries for your OS and window
+system.  It does not need the headers for any context creation API (WGL, GLX,
+EGL, NSGL, OSMesa) or rendering API (OpenGL, OpenGL ES, Vulkan) to enable
+support for them.
+
+GLFW supports compilation on Windows with Visual C++ 2010 and later, MinGW and
+MinGW-w64, on macOS with Clang and on Linux and other Unix-like systems with GCC
+and Clang.  It will likely compile in other environments as well, but this is
+not regularly tested.
+
+There are [pre-compiled Windows binaries](http://www.glfw.org/download.html)
+available for all supported compilers.
+
+See the [compilation guide](http://www.glfw.org/docs/latest/compile.html) for
+more information about how to compile GLFW yourself.
+
+
+## Using GLFW
+
+See the [documentation](http://www.glfw.org/docs/latest/) for tutorials, guides
+and the API reference.
+
+
+## Contributing to GLFW
+
+See the [contribution
+guide](https://github.com/glfw/glfw/blob/master/docs/CONTRIBUTING.md) for
+more information.
+
+
+## System requirements
+
+GLFW supports Windows XP and later and macOS 10.8 and later.  Linux and other
+Unix-like systems running the X Window System are supported even without
+a desktop environment or modern extensions, although some features require
+a running window or clipboard manager.  The OSMesa backend requires Mesa 6.3.
+
+See the [compatibility guide](http://www.glfw.org/docs/latest/compat.html)
+in the documentation for more information.
+
+
+## Dependencies
+
+GLFW itself depends only on the headers and libraries for your window system.
+
+The (experimental) Wayland backend also depends on the `extra-cmake-modules`
+package, which is used to generate Wayland protocol headers.
+
+The examples and test programs depend on a number of tiny libraries.  These are
+located in the `deps/` directory.
+
+ - [getopt\_port](https://github.com/kimgr/getopt_port/) for examples
+   with command-line options
+ - [TinyCThread](https://github.com/tinycthread/tinycthread) for threaded
+   examples
+ - [glad2](https://github.com/Dav1dde/glad) for loading OpenGL and Vulkan
+   functions
+ - [linmath.h](https://github.com/datenwolf/linmath.h) for linear algebra in
+   examples
+ - [Nuklear](https://github.com/vurtun/nuklear) for test and example UI
+ - [stb\_image\_write](https://github.com/nothings/stb) for writing images to disk
+
+The documentation is generated with [Doxygen](http://doxygen.org/) if CMake can
+find that tool.
+
+
+## Reporting bugs
+
+Bugs are reported to our [issue tracker](https://github.com/glfw/glfw/issues).
+Please check the [contribution
+guide](https://github.com/glfw/glfw/blob/master/docs/CONTRIBUTING.md) for
+information on what to include when reporting a bug.
+
+
+## Changelog

+ *
+ * The types in khrplatform.h should only be used to define API-specific types.

+/// ## About
+/// This is a minimal state immediate mode graphical user interface toolkit
+/// written in ANSI C and licensed under public domain. It was designed as a simple
+/// embeddable user interface for application and does not have any dependencies,
+/// a default renderbackend or OS window and input handling but instead provides a very modular
+/// library approach by using simple input state for input and draw
+/// commands describing primitive shapes as output. So instead of providing a
+/// layered library that tries to abstract over a number of platform and
+/// render backends it only focuses on the actual UI.
+///
+/// ## Highlights
+/// - Graphical user interface toolkit
+/// - Single header library
+/// - Written in C89 (a.k.a. ANSI C or ISO C90)
+/// - Small codebase (~18kLOC)
+/// - Focus on portability, efficiency and simplicity
+/// - No dependencies (not even the standard library if not wanted)
+/// - Fully skinnable and customizable
+/// - Low memory footprint with total memory control if needed or wanted
+/// - UTF-8 support
+/// - No global or hidden state
+/// - Customizable library modules (you can compile and use only what you need)
+/// - Optional font baker and vertex buffer output
+///
+/// ## Features
+/// - Absolutely no platform dependent code
+/// - Memory management control ranging from/to
+///     - Ease of use by allocating everything from standard library
+///     - Control every byte of memory inside the library
+/// - Font handling control ranging from/to
+///     - Use your own font implementation for everything
+///     - Use this libraries internal font baking and handling API
+/// - Drawing output control ranging from/to
+///     - Simple shapes for more high level APIs which already have drawing capabilities
+///     - Hardware accessible anti-aliased vertex buffer output
+/// - Customizable colors and properties ranging from/to
+///     - Simple changes to color by filling a simple color table
+///     - Complete control with ability to use skinning to decorate widgets
+/// - Bendable UI library with widget ranging from/to
+///     - Basic widgets like buttons, checkboxes, slider, ...
+///     - Advanced widget like abstract comboboxes, contextual menus,...
+/// - Compile time configuration to only compile what you need
+///     - Subset which can be used if you do not want to link or use the standard library
+/// - Can be easily modified to only update on user input instead of frame updates
+///
+/// ## Usage
+/// This library is self contained in one single header file and can be used either
+/// in header only mode or in implementation mode. The header only mode is used
+/// by default when included and allows including this header in other headers
+/// and does not contain the actual implementation. <br /><br />
+///
+/// The implementation mode requires to define  the preprocessor macro
+/// NK_IMPLEMENTATION in *one* .c/.cpp file before #includeing this file, e.g.:
+///
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~C
+///     #define NK_IMPLEMENTATION
+///     #include "nuklear.h"
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+/// Also optionally define the symbols listed in the section "OPTIONAL DEFINES"
+/// below in header and implementation mode if you want to use additional functionality
+/// or need more control over the library.
+///
+/// !!! WARNING
+///     Every time nuklear is included define the same compiler flags. This very important not doing so could lead to compiler errors or even worse stack corruptions.
+///
+/// ### Flags
+/// Flag                            | Description
+/// --------------------------------|------------------------------------------
+/// NK_PRIVATE                      | If defined declares all functions as static, so they can only be accessed inside the file that contains the implementation
+/// NK_INCLUDE_FIXED_TYPES          | If defined it will include header `<stdint.h>` for fixed sized types otherwise nuklear tries to select the correct type. If that fails it will throw a compiler error and you have to select the correct types yourself.
+/// NK_INCLUDE_DEFAULT_ALLOCATOR    | If defined it will include header `<stdlib.h>` and provide additional functions to use this library without caring for memory allocation control and therefore ease memory management.
+/// NK_INCLUDE_STANDARD_IO          | If defined it will include header `<stdio.h>` and provide additional functions depending on file loading.
+/// NK_INCLUDE_STANDARD_VARARGS     | If defined it will include header <stdio.h> and provide additional functions depending on file loading.
+/// NK_INCLUDE_VERTEX_BUFFER_OUTPUT | Defining this adds a vertex draw command list backend to this library, which allows you to convert queue commands into vertex draw commands. This is mainly if you need a hardware accessible format for OpenGL, DirectX, Vulkan, Metal,...
+/// NK_INCLUDE_FONT_BAKING          | Defining this adds `stb_truetype` and `stb_rect_pack` implementation to this library and provides font baking and rendering. If you already have font handling or do not want to use this font handler you don't have to define it.
+/// NK_INCLUDE_DEFAULT_FONT         | Defining this adds the default font: ProggyClean.ttf into this library which can be loaded into a font atlas and allows using this library without having a truetype font
+/// NK_INCLUDE_COMMAND_USERDATA     | Defining this adds a userdata pointer into each command. Can be useful for example if you want to provide custom shaders depending on the used widget. Can be combined with the style structures.
+/// NK_BUTTON_TRIGGER_ON_RELEASE    | Different platforms require button clicks occurring either on buttons being pressed (up to down) or released (down to up). By default this library will react on buttons being pressed, but if you define this it will only trigger if a button is released.
+/// NK_ZERO_COMMAND_MEMORY          | Defining this will zero out memory for each drawing command added to a drawing queue (inside nk_command_buffer_push). Zeroing command memory is very useful for fast checking (using memcmp) if command buffers are equal and avoid drawing frames when nothing on screen has changed since previous frame.
+///
+/// !!! WARNING
+///     The following flags will pull in the standard C library:
+///     - NK_INCLUDE_DEFAULT_ALLOCATOR
+///     - NK_INCLUDE_STANDARD_IO
+///     - NK_INCLUDE_STANDARD_VARARGS
+///
+/// !!! WARNING
+///     The following flags if defined need to be defined for both header and implementation:
+///     - NK_INCLUDE_FIXED_TYPES
+///     - NK_INCLUDE_DEFAULT_ALLOCATOR
+///     - NK_INCLUDE_STANDARD_VARARGS
+///     - NK_INCLUDE_VERTEX_BUFFER_OUTPUT
+///     - NK_INCLUDE_FONT_BAKING
+///     - NK_INCLUDE_DEFAULT_FONT
+///     - NK_INCLUDE_STANDARD_VARARGS
+///     - NK_INCLUDE_COMMAND_USERDATA
+///
+/// ### Constants
+/// Define                          | Description
+/// --------------------------------|---------------------------------------
+/// NK_BUFFER_DEFAULT_INITIAL_SIZE  | Initial buffer size allocated by all buffers while using the default allocator functions included by defining NK_INCLUDE_DEFAULT_ALLOCATOR. If you don't want to allocate the default 4k memory then redefine it.
+/// NK_MAX_NUMBER_BUFFER            | Maximum buffer size for the conversion buffer between float and string Under normal circumstances this should be more than sufficient.
+/// NK_INPUT_MAX                    | Defines the max number of bytes which can be added as text input in one frame. Under normal circumstances this should be more than sufficient.
+///
+/// !!! WARNING
+///     The following constants if defined need to be defined for both header and implementation:
+///     - NK_MAX_NUMBER_BUFFER
+///     - NK_BUFFER_DEFAULT_INITIAL_SIZE
+///     - NK_INPUT_MAX
+///
+/// ### Dependencies
+/// Function    | Description
+/// ------------|---------------------------------------------------------------
+/// NK_ASSERT   | If you don't define this, nuklear will use <assert.h> with assert().
+/// NK_MEMSET   | You can define this to 'memset' or your own memset implementation replacement. If not nuklear will use its own version.
+/// NK_MEMCPY   | You can define this to 'memcpy' or your own memcpy implementation replacement. If not nuklear will use its own version.
+/// NK_SQRT     | You can define this to 'sqrt' or your own sqrt implementation replacement. If not nuklear will use its own slow and not highly accurate version.
+/// NK_SIN      | You can define this to 'sinf' or your own sine implementation replacement. If not nuklear will use its own approximation implementation.
+/// NK_COS      | You can define this to 'cosf' or your own cosine implementation replacement. If not nuklear will use its own approximation implementation.
+/// NK_STRTOD   | You can define this to `strtod` or your own string to double conversion implementation replacement. If not defined nuklear will use its own imprecise and possibly unsafe version (does not handle nan or infinity!).
+/// NK_DTOA     | You can define this to `dtoa` or your own double to string conversion implementation replacement. If not defined nuklear will use its own imprecise and possibly unsafe version (does not handle nan or infinity!).
+/// NK_VSNPRINTF| If you define `NK_INCLUDE_STANDARD_VARARGS` as well as `NK_INCLUDE_STANDARD_IO` and want to be safe define this to `vsnprintf` on compilers supporting later versions of C or C++. By default nuklear will check for your stdlib version in C as well as compiler version in C++. if `vsnprintf` is available it will define it to `vsnprintf` directly. If not defined and if you have older versions of C or C++ it will be defined to `vsprintf` which is unsafe.
+///
+/// !!! WARNING
+///     The following dependencies will pull in the standard C library if not redefined:
+///     - NK_ASSERT
+///
+/// !!! WARNING
+///     The following dependencies if defined need to be defined for both header and implementation:
+///     - NK_ASSERT
+///
+/// !!! WARNING
+///     The following dependencies if defined need to be defined only for the implementation part:
+///     - NK_MEMSET
+///     - NK_MEMCPY
+///     - NK_SQRT
+///     - NK_SIN
+///     - NK_COS
+///     - NK_STRTOD
+///     - NK_DTOA
+///     - NK_VSNPRINTF
+///
+/// ## Example
+///
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+/// // init gui state
+/// enum {EASY, HARD};
+/// static int op = EASY;
+/// static float value = 0.6f;
+/// static int i =  20;
+/// struct nk_context ctx;
+///

+ *
+ * =============================================================================*/
+/*/// ### Drawing
+/// This library was designed to be render backend agnostic so it does
+/// not draw anything to screen directly. Instead all drawn shapes, widgets
+/// are made of, are buffered into memory and make up a command queue.
+/// Each frame therefore fills the command buffer with draw commands
+/// that then need to be executed by the user and his own render backend.
+/// After that the command buffer needs to be cleared and a new frame can be
+/// started. It is probably important to note that the command buffer is the main
+/// drawing API and the optional vertex buffer API only takes this format and
+/// converts it into a hardware accessible format.
+///
+/// #### Usage
+/// To draw all draw commands accumulated over a frame you need your own render
+/// backend able to draw a number of 2D primitives. This includes at least
+/// filled and stroked rectangles, circles, text, lines, triangles and scissors.
+/// As soon as this criterion is met you can iterate over each draw command
+/// and execute each draw command in a interpreter like fashion:
+///
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+/// const struct nk_command *cmd = 0;
+/// nk_foreach(cmd, &ctx) {
+///     switch (cmd->type) {
+///     case NK_COMMAND_LINE:
+///         your_draw_line_function(...)
+///         break;
+///     case NK_COMMAND_RECT
+///         your_draw_rect_function(...)
+///         break;
+///     case //...:
+///         //[...]
+///     }
+/// }
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+/// In program flow context draw commands need to be executed after input has been
+/// gathered and the complete UI with windows and their contained widgets have
+/// been executed and before calling `nk_clear` which frees all previously
+/// allocated draw commands.
+///
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+/// struct nk_context ctx;
+/// nk_init_xxx(&ctx, ...);
+/// while (1) {
+///     Event evt;
+///     nk_input_begin(&ctx);
+///     while (GetEvent(&evt)) {
+///         if (evt.type == MOUSE_MOVE)
+///             nk_input_motion(&ctx, evt.motion.x, evt.motion.y);
+///         else if (evt.type == [...]) {
+///             [...]
+///         }
+///     }
+///     nk_input_end(&ctx);
+///     //
+///     // [...]
+///     //
+///     const struct nk_command *cmd = 0;
+///     nk_foreach(cmd, &ctx) {
+///     switch (cmd->type) {
+///     case NK_COMMAND_LINE:
+///         your_draw_line_function(...)
+///         break;
+///     case NK_COMMAND_RECT
+///         your_draw_rect_function(...)
+///         break;
+///     case ...:
+///         // [...]
+///     }
+///     nk_clear(&ctx);
+/// }
+/// nk_free(&ctx);
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+/// You probably noticed that you have to draw all of the UI each frame which is
+/// quite wasteful. While the actual UI updating loop is quite fast rendering
+/// without actually needing it is not. So there are multiple things you could do.
+///
+/// First is only update on input. This of course is only an option if your
+/// application only depends on the UI and does not require any outside calculations.
+/// If you actually only update on input make sure to update the UI two times each
+/// frame and call `nk_clear` directly after the first pass and only draw in
+/// the second pass. In addition it is recommended to also add additional timers
+/// to make sure the UI is not drawn more than a fixed number of frames per second.
+///
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+/// struct nk_context ctx;
+/// nk_init_xxx(&ctx, ...);
+/// while (1) {
+///     // [...wait for input ]
+///     // [...do two UI passes ...]
+///     do_ui(...)
+///     nk_clear(&ctx);
+///     do_ui(...)
+///     //
+///     // draw
+///     const struct nk_command *cmd = 0;
+///     nk_foreach(cmd, &ctx) {
+///     switch (cmd->type) {
+///     case NK_COMMAND_LINE:
+///         your_draw_line_function(...)
+///         break;
+///     case NK_COMMAND_RECT
+///         your_draw_rect_function(...)
+///         break;
+///     case ...:
+///         //[...]
+///     }
+///     nk_clear(&ctx);
+/// }
+/// nk_free(&ctx);
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+/// The second probably more applicable trick is to only draw if anything changed.
+/// It is not really useful for applications with continuous draw loop but
+/// quite useful for desktop applications. To actually get nuklear to only
+/// draw on changes you first have to define `NK_ZERO_COMMAND_MEMORY` and
+/// allocate a memory buffer that will store each unique drawing output.
+/// After each frame you compare the draw command memory inside the library
+/// with your allocated buffer by memcmp. If memcmp detects differences
+/// you have to copy the command buffer into the allocated buffer
+/// and then draw like usual (this example uses fixed memory but you could
+/// use dynamically allocated memory).
+///
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+/// //[... other defines ...]
+/// #define NK_ZERO_COMMAND_MEMORY
+/// #include "nuklear.h"
+/// //
+/// // setup context
+/// struct nk_context ctx;
+/// void *last = calloc(1,64*1024);
+/// void *buf = calloc(1,64*1024);
+/// nk_init_fixed(&ctx, buf, 64*1024);
+/// //
+/// // loop
+/// while (1) {
+///     // [...input...]
+///     // [...ui...]
+///     void *cmds = nk_buffer_memory(&ctx.memory);
+///     if (memcmp(cmds, last, ctx.memory.allocated)) {
+///         memcpy(last,cmds,ctx.memory.allocated);
+///         const struct nk_command *cmd = 0;
+///         nk_foreach(cmd, &ctx) {
+///             switch (cmd->type) {
+///             case NK_COMMAND_LINE:
+///                 your_draw_line_function(...)
+///                 break;
+///             case NK_COMMAND_RECT
+///                 your_draw_rect_function(...)
+///                 break;
+///             case ...:
+///                 // [...]
+///             }
+///         }
+///     }
+///     nk_clear(&ctx);
+/// }
+/// nk_free(&ctx);
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+/// Finally while using draw commands makes sense for higher abstracted platforms like
+/// X11 and Win32 or drawing libraries it is often desirable to use graphics
+/// hardware directly. Therefore it is possible to just define
+/// `NK_INCLUDE_VERTEX_BUFFER_OUTPUT` which includes optional vertex output.
+/// To access the vertex output you first have to convert all draw commands into
+/// vertexes by calling `nk_convert` which takes in your preferred vertex format.
+/// After successfully converting all draw commands just iterate over and execute all

+ *                                  WINDOW
+ *
+ * =============================================================================
+/// ### Window
+/// Windows are the main persistent state used inside nuklear and are life time
+/// controlled by simply "retouching" (i.e. calling) each window each frame.
+/// All widgets inside nuklear can only be added inside the function pair `nk_begin_xxx`
+/// and `nk_end`. Calling any widgets outside these two functions will result in an
+/// assert in debug or no state change in release mode.<br /><br />
+///
+/// Each window holds frame persistent state like position, size, flags, state tables,
+/// and some garbage collected internal persistent widget state. Each window
+/// is linked into a window stack list which determines the drawing and overlapping
+/// order. The topmost window thereby is the currently active window.<br /><br />
+///
+/// To change window position inside the stack occurs either automatically by
+/// user input by being clicked on or programmatically by calling `nk_window_focus`.
+/// Windows by default are visible unless explicitly being defined with flag
+/// `NK_WINDOW_HIDDEN`, the user clicked the close button on windows with flag
+/// `NK_WINDOW_CLOSABLE` or if a window was explicitly hidden by calling
+/// `nk_window_show`. To explicitly close and destroy a window call `nk_window_close`.<br /><br />
+///
+/// #### Usage
+/// To create and keep a window you have to call one of the two `nk_begin_xxx`
+/// functions to start window declarations and `nk_end` at the end. Furthermore it
+/// is recommended to check the return value of `nk_begin_xxx` and only process
+/// widgets inside the window if the value is not 0. Either way you have to call
+/// `nk_end` at the end of window declarations. Furthermore, do not attempt to
+/// nest `nk_begin_xxx` calls which will hopefully result in an assert or if not
+/// in a segmentation fault.
+///
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+/// if (nk_begin_xxx(...) {
+///     // [... widgets ...]
+/// }
+/// nk_end(ctx);
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+/// In the grand concept window and widget declarations need to occur after input
+/// handling and before drawing to screen. Not doing so can result in higher
+/// latency or at worst invalid behavior. Furthermore make sure that `nk_clear`
+/// is called at the end of the frame. While nuklear's default platform backends
+/// already call `nk_clear` for you if you write your own backend not calling
+/// `nk_clear` can cause asserts or even worse undefined behavior.
+///
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+/// struct nk_context ctx;
+/// nk_init_xxx(&ctx, ...);

+///     Event evt;

+ *
+ * =============================================================================
+/// ### Layouting
+/// Layouting in general describes placing widget inside a window with position and size.
+/// While in this particular implementation there are five different APIs for layouting
+/// each with different trade offs between control and ease of use. <br /><br />
+///
+/// All layouting methods in this library are based around the concept of a row.
+/// A row has a height the window content grows by and a number of columns and each
+/// layouting method specifies how each widget is placed inside the row.
+/// After a row has been allocated by calling a layouting functions and then
+/// filled with widgets will advance an internal pointer over the allocated row. <br /><br />
+///
+/// To actually define a layout you just call the appropriate layouting function
+/// and each subsequent widget call will place the widget as specified. Important
+/// here is that if you define more widgets then columns defined inside the layout
+/// functions it will allocate the next row without you having to make another layouting <br /><br />
+/// call.
+///
+/// Biggest limitation with using all these APIs outside the `nk_layout_space_xxx` API
+/// is that you have to define the row height for each. However the row height
+/// often depends on the height of the font. <br /><br />
+///
+/// To fix that internally nuklear uses a minimum row height that is set to the
+/// height plus padding of currently active font and overwrites the row height
+/// value if zero. <br /><br />
+///
+/// If you manually want to change the minimum row height then
+/// use nk_layout_set_min_row_height, and use nk_layout_reset_min_row_height to
+/// reset it back to be derived from font height. <br /><br />
+///
+/// Also if you change the font in nuklear it will automatically change the minimum
+/// row height for you and. This means if you change the font but still want
+/// a minimum row height smaller than the font you have to repush your value. <br /><br />
+///
+/// For actually more advanced UI I would even recommend using the `nk_layout_space_xxx`
+/// layouting method in combination with a cassowary constraint solver (there are
+/// some versions on github with permissive license model) to take over all control over widget
+/// layouting yourself. However for quick and dirty layouting using all the other layouting
+/// functions should be fine.
+///
+/// #### Usage
+/// 1.  __nk_layout_row_dynamic__<br /><br />
+///     The easiest layouting function is `nk_layout_row_dynamic`. It provides each
+///     widgets with same horizontal space inside the row and dynamically grows
+///     if the owning window grows in width. So the number of columns dictates
+///     the size of each widget dynamically by formula:
+///
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+///     widget_width = (window_width - padding - spacing) * (1/colum_count)
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+///     Just like all other layouting APIs if you define more widget than columns this
+///     library will allocate a new row and keep all layouting parameters previously
+///     defined.
+///
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+///     if (nk_begin_xxx(...) {
+///         // first row with height: 30 composed of two widgets
+///         nk_layout_row_dynamic(&ctx, 30, 2);
+///         nk_widget(...);
+///         nk_widget(...);
+///         //
+///         // second row with same parameter as defined above
+///         nk_widget(...);
+///         nk_widget(...);
+///         //
+///         // third row uses 0 for height which will use auto layouting
+///         nk_layout_row_dynamic(&ctx, 0, 2);
+///         nk_widget(...);
+///         nk_widget(...);
+///     }
+///     nk_end(...);
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+/// 2.  __nk_layout_row_static__<br /><br />
+///     Another easy layouting function is `nk_layout_row_static`. It provides each
+///     widget with same horizontal pixel width inside the row and does not grow
+///     if the owning window scales smaller or bigger.
+///
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+///     if (nk_begin_xxx(...) {
+///         // first row with height: 30 composed of two widgets with width: 80
+///         nk_layout_row_static(&ctx, 30, 80, 2);
+///         nk_widget(...);
+///         nk_widget(...);
+///         //
+///         // second row with same parameter as defined above
+///         nk_widget(...);
+///         nk_widget(...);
+///         //
+///         // third row uses 0 for height which will use auto layouting
+///         nk_layout_row_static(&ctx, 0, 80, 2);
+///         nk_widget(...);
+///         nk_widget(...);
+///     }
+///     nk_end(...);
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+/// 3.  __nk_layout_row_xxx__<br /><br />
+///     A little bit more advanced layouting API are functions `nk_layout_row_begin`,
+///     `nk_layout_row_push` and `nk_layout_row_end`. They allow to directly
+///     specify each column pixel or window ratio in a row. It supports either
+///     directly setting per column pixel width or widget window ratio but not
+///     both. Furthermore it is a immediate mode API so each value is directly
+///     pushed before calling a widget. Therefore the layout is not automatically
+///     repeating like the last two layouting functions.
+///
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+///     if (nk_begin_xxx(...) {
+///         // first row with height: 25 composed of two widgets with width 60 and 40
+///         nk_layout_row_begin(ctx, NK_STATIC, 25, 2);
+///         nk_layout_row_push(ctx, 60);
+///         nk_widget(...);
+///         nk_layout_row_push(ctx, 40);
+///         nk_widget(...);
+///         nk_layout_row_end(ctx);
+///         //
+///         // second row with height: 25 composed of two widgets with window ratio 0.25 and 0.75
+///         nk_layout_row_begin(ctx, NK_DYNAMIC, 25, 2);
+///         nk_layout_row_push(ctx, 0.25f);
+///         nk_widget(...);
+///         nk_layout_row_push(ctx, 0.75f);
+///         nk_widget(...);
+///         nk_layout_row_end(ctx);
+///         //
+///         // third row with auto generated height: composed of two widgets with window ratio 0.25 and 0.75
+///         nk_layout_row_begin(ctx, NK_DYNAMIC, 0, 2);
+///         nk_layout_row_push(ctx, 0.25f);
+///         nk_widget(...);
+///         nk_layout_row_push(ctx, 0.75f);
+///         nk_widget(...);
+///         nk_layout_row_end(ctx);
+///     }
+///     nk_end(...);
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+/// 4.  __nk_layout_row__<br /><br />
+///     The array counterpart to API nk_layout_row_xxx is the single nk_layout_row
+///     functions. Instead of pushing either pixel or window ratio for every widget
+///     it allows to define it by array. The trade of for less control is that
+///     `nk_layout_row` is automatically repeating. Otherwise the behavior is the
+///     same.
+///
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+///     if (nk_begin_xxx(...) {
+///         // two rows with height: 30 composed of two widgets with width 60 and 40
+///         const float size[] = {60,40};
+///         nk_layout_row(ctx, NK_STATIC, 30, 2, ratio);
+///         nk_widget(...);
+///         nk_widget(...);
+///         nk_widget(...);
+///         nk_widget(...);
+///         //
+///         // two rows with height: 30 composed of two widgets with window ratio 0.25 and 0.75
+///         const float ratio[] = {0.25, 0.75};
+///         nk_layout_row(ctx, NK_DYNAMIC, 30, 2, ratio);
+///         nk_widget(...);
+///         nk_widget(...);
+///         nk_widget(...);
+///         nk_widget(...);
+///         //
+///         // two rows with auto generated height composed of two widgets with window ratio 0.25 and 0.75
+///         const float ratio[] = {0.25, 0.75};
+///         nk_layout_row(ctx, NK_DYNAMIC, 30, 2, ratio);
+///         nk_widget(...);
+///         nk_widget(...);
+///         nk_widget(...);
+///         nk_widget(...);
+///     }
+///     nk_end(...);
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+/// 5.  __nk_layout_row_template_xxx__<br /><br />
+///     The most complex and second most flexible API is a simplified flexbox version without
+///     line wrapping and weights for dynamic widgets. It is an immediate mode API but
+///     unlike `nk_layout_row_xxx` it has auto repeat behavior and needs to be called
+///     before calling the templated widgets.
+///     The row template layout has three different per widget size specifier. The first
+///     one is the `nk_layout_row_template_push_static`  with fixed widget pixel width.
+///     They do not grow if the row grows and will always stay the same.
+///     The second size specifier is `nk_layout_row_template_push_variable`
+///     which defines a minimum widget size but it also can grow if more space is available
+///     not taken by other widgets.
+///     Finally there are dynamic widgets with `nk_layout_row_template_push_dynamic`
+///     which are completely flexible and unlike variable widgets can even shrink
+///     to zero if not enough space is provided.
+///
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+///     if (nk_begin_xxx(...) {
+///         // two rows with height: 30 composed of three widgets
+///         nk_layout_row_template_begin(ctx, 30);
+///         nk_layout_row_template_push_dynamic(ctx);
+///         nk_layout_row_template_push_variable(ctx, 80);
+///         nk_layout_row_template_push_static(ctx, 80);
+///         nk_layout_row_template_end(ctx);
+///         //
+///         // first row
+///         nk_widget(...); // dynamic widget can go to zero if not enough space
+///         nk_widget(...); // variable widget with min 80 pixel but can grow bigger if enough space
+///         nk_widget(...); // static widget with fixed 80 pixel width
+///         //
+///         // second row same layout
+///         nk_widget(...);
+///         nk_widget(...);
+///         nk_widget(...);
+///     }
+///     nk_end(...);
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+/// 6.  __nk_layout_space_xxx__<br /><br />
+///     Finally the most flexible API directly allows you to place widgets inside the
+///     window. The space layout API is an immediate mode API which does not support
+///     row auto repeat and directly sets position and size of a widget. Position
+///     and size hereby can be either specified as ratio of allocated space or
+///     allocated space local position and pixel size. Since this API is quite
+///     powerful there are a number of utility functions to get the available space
+///     and convert between local allocated space and screen space.
+///
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+///     if (nk_begin_xxx(...) {
+///         // static row with height: 500 (you can set column count to INT_MAX if you don't want to be bothered)
+///         nk_layout_space_begin(ctx, NK_STATIC, 500, INT_MAX);
+///         nk_layout_space_push(ctx, nk_rect(0,0,150,200));
+///         nk_widget(...);
+///         nk_layout_space_push(ctx, nk_rect(200,200,100,200));
+///         nk_widget(...);
+///         nk_layout_space_end(ctx);
+///         //
+///         // dynamic row with height: 500 (you can set column count to INT_MAX if you don't want to be bothered)
+///         nk_layout_space_begin(ctx, NK_DYNAMIC, 500, INT_MAX);
+///         nk_layout_space_push(ctx, nk_rect(0.5,0.5,0.1,0.1));
+///         nk_widget(...);
+///         nk_layout_space_push(ctx, nk_rect(0.7,0.6,0.1,0.1));

+ *                                  GROUP
+ *
+ * =============================================================================
+/// ### Groups
+/// Groups are basically windows inside windows. They allow to subdivide space
+/// in a window to layout widgets as a group. Almost all more complex widget
+/// layouting requirements can be solved using groups and basic layouting
+/// fuctionality. Groups just like windows are identified by an unique name and
+/// internally keep track of scrollbar offsets by default. However additional
+/// versions are provided to directly manage the scrollbar.
+///
+/// #### Usage
+/// To create a group you have to call one of the three `nk_group_begin_xxx`
+/// functions to start group declarations and `nk_group_end` at the end. Furthermore it
+/// is required to check the return value of `nk_group_begin_xxx` and only process
+/// widgets inside the window if the value is not 0.
+/// Nesting groups is possible and even encouraged since many layouting schemes
+/// can only be achieved by nesting. Groups, unlike windows, need `nk_group_end`
+/// to be only called if the corosponding `nk_group_begin_xxx` call does not return 0:
+///
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+/// if (nk_group_begin_xxx(ctx, ...) {
+///     // [... widgets ...]
+///     nk_group_end(ctx);
+/// }
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+/// In the grand concept groups can be called after starting a window
+/// with `nk_begin_xxx` and before calling `nk_end`:
+///
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+/// struct nk_context ctx;
+/// nk_init_xxx(&ctx, ...);
+/// while (1) {
+///     // Input
+///     Event evt;
+///     nk_input_begin(&ctx);
+///     while (GetEvent(&evt)) {
+///         if (evt.type == MOUSE_MOVE)
+///             nk_input_motion(&ctx, evt.motion.x, evt.motion.y);
+///         else if (evt.type == [...]) {
+///             nk_input_xxx(...);
+///         }
+///     }
+///     nk_input_end(&ctx);
+///     //
+///     // Window
+///     if (nk_begin_xxx(...) {
+///         // [...widgets...]
+///         nk_layout_row_dynamic(...);
+///         if (nk_group_begin_xxx(ctx, ...) {
+///             //[... widgets ...]
+///             nk_group_end(ctx);
+///         }
+///     }
+///     nk_end(ctx);
+///     //
+///     // Draw
+///     const struct nk_command *cmd = 0;
+///     nk_foreach(cmd, &ctx) {
+///     switch (cmd->type) {

+ *
+ * ============================================================================= 
+/// ### Tree
+/// Trees represent two different concept. First the concept of a collapsable
+/// UI section that can be either in a hidden or visibile state. They allow the UI
+/// user to selectively minimize the current set of visible UI to comprehend.
+/// The second concept are tree widgets for visual UI representation of trees.<br /><br />
+///
+/// Trees thereby can be nested for tree representations and multiple nested
+/// collapsable UI sections. All trees are started by calling of the
+/// `nk_tree_xxx_push_tree` functions and ended by calling one of the
+/// `nk_tree_xxx_pop_xxx()` functions. Each starting functions takes a title label
+/// and optionally an image to be displayed and the initial collapse state from
+/// the nk_collapse_states section.<br /><br />
+///
+/// The runtime state of the tree is either stored outside the library by the caller
+/// or inside which requires a unique ID. The unique ID can either be generated
+/// automatically from `__FILE__` and `__LINE__` with function `nk_tree_push`,
+/// by `__FILE__` and a user provided ID generated for example by loop index with
+/// function `nk_tree_push_id` or completely provided from outside by user with
+/// function `nk_tree_push_hashed`.
+///
+/// #### Usage
+/// To create a tree you have to call one of the seven `nk_tree_xxx_push_xxx`
+/// functions to start a collapsable UI section and `nk_tree_xxx_pop` to mark the
+/// end.
+/// Each starting function will either return `false(0)` if the tree is collapsed
+/// or hidden and therefore does not need to be filled with content or `true(1)`
+/// if visible and required to be filled.
+///
+/// !!! Note
+///     The tree header does not require and layouting function and instead
+///     calculates a auto height based on the currently used font size
+///
+/// The tree ending functions only need to be called if the tree content is
+/// actually visible. So make sure the tree push function is guarded by `if`
+/// and the pop call is only taken if the tree is visible.

+/// ### Properties
+/// Properties are the main value modification widgets in Nuklear. Changing a value
+/// can be achieved by dragging, adding/removing incremental steps on button click
+/// or by directly typing a number.
+///
+/// #### Usage
+/// Each property requires a unique name for identifaction that is also used for
+/// displaying a label. If you want to use the same name multiple times make sure
+/// add a '#' before your name. The '#' will not be shown but will generate a
+/// unique ID. Each propery also takes in a minimum and maximum value. If you want
+/// to make use of the complete number range of a type just use the provided
+/// type limits from `limits.h`. For example `INT_MIN` and `INT_MAX` for
+/// `nk_property_int` and `nk_propertyi`. In additional each property takes in
+/// a increment value that will be added or subtracted if either the increment
+/// decrement button is clicked. Finally there is a value for increment per pixel
+/// dragged that is added or subtracted from the value.

+/*  Font handling in this library was designed to be quite customizable and lets
+    you decide what you want to use and what you want to provide. There are three
+    different ways to use the font atlas. The first two will use your font
+    handling scheme and only requires essential data to run nuklear. The next
+    slightly more advanced features is font handling with vertex buffer output.
+    Finally the most complex API wise is using nuklear's font baking API.
+
+    1.) Using your own implementation without vertex buffer output
+    --------------------------------------------------------------
+    So first up the easiest way to do font handling is by just providing a
+    `nk_user_font` struct which only requires the height in pixel of the used
+    font and a callback to calculate the width of a string. This way of handling
+    fonts is best fitted for using the normal draw shape command API where you
+    do all the text drawing yourself and the library does not require any kind
+    of deeper knowledge about which font handling mechanism you use.
+    IMPORTANT: the `nk_user_font` pointer provided to nuklear has to persist
+    over the complete life time! I know this sucks but it is currently the only
+    way to switch between fonts.
+
+        float your_text_width_calculation(nk_handle handle, float height, const char *text, int len)
+        {
+            your_font_type *type = handle.ptr;
+            float text_width = ...;
+            return text_width;
+        }
+
+        struct nk_user_font font;
+        font.userdata.ptr = &your_font_class_or_struct;
+        font.height = your_font_height;
+        font.width = your_text_width_calculation;
+
+        struct nk_context ctx;
+        nk_init_default(&ctx, &font);
+
+    2.) Using your own implementation with vertex buffer output
+    --------------------------------------------------------------
+    While the first approach works fine if you don't want to use the optional
+    vertex buffer output it is not enough if you do. To get font handling working
+    for these cases you have to provide two additional parameters inside the
+    `nk_user_font`. First a texture atlas handle used to draw text as subimages
+    of a bigger font atlas texture and a callback to query a character's glyph
+    information (offset, size, ...). So it is still possible to provide your own
+    font and use the vertex buffer output.
+
+        float your_text_width_calculation(nk_handle handle, float height, const char *text, int len)
+        {
+            your_font_type *type = handle.ptr;
+            float text_width = ...;
+            return text_width;
+        }
+        void query_your_font_glyph(nk_handle handle, float font_height, struct nk_user_font_glyph *glyph, nk_rune codepoint, nk_rune next_codepoint)
+        {
+            your_font_type *type = handle.ptr;
+            glyph.width = ...;
+            glyph.height = ...;
+            glyph.xadvance = ...;
+            glyph.uv[0].x = ...;
+            glyph.uv[0].y = ...;
+            glyph.uv[1].x = ...;
+            glyph.uv[1].y = ...;
+            glyph.offset.x = ...;
+            glyph.offset.y = ...;
+        }
+
+        struct nk_user_font font;
+        font.userdata.ptr = &your_font_class_or_struct;
+        font.height = your_font_height;
+        font.width = your_text_width_calculation;
+        font.query = query_your_font_glyph;
+        font.texture.id = your_font_texture;
+
+        struct nk_context ctx;
+        nk_init_default(&ctx, &font);
+
+    3.) Nuklear font baker
+    ------------------------------------
+    The final approach if you do not have a font handling functionality or don't
+    want to use it in this library is by using the optional font baker.
+    The font baker APIs can be used to create a font plus font atlas texture
+    and can be used with or without the vertex buffer output.
+
+    It still uses the `nk_user_font` struct and the two different approaches
+    previously stated still work. The font baker is not located inside
+    `nk_context` like all other systems since it can be understood as more of
+    an extension to nuklear and does not really depend on any `nk_context` state.
+
+    Font baker need to be initialized first by one of the nk_font_atlas_init_xxx
+    functions. If you don't care about memory just call the default version
+    `nk_font_atlas_init_default` which will allocate all memory from the standard library.
+    If you want to control memory allocation but you don't care if the allocated
+    memory is temporary and therefore can be freed directly after the baking process
+    is over or permanent you can call `nk_font_atlas_init`.
+
+    After successfully initializing the font baker you can add Truetype(.ttf) fonts from
+    different sources like memory or from file by calling one of the `nk_font_atlas_add_xxx`.
+    functions. Adding font will permanently store each font, font config and ttf memory block(!)
+    inside the font atlas and allows to reuse the font atlas. If you don't want to reuse
+    the font baker by for example adding additional fonts you can call
+    `nk_font_atlas_cleanup` after the baking process is over (after calling nk_font_atlas_end).
+
+    As soon as you added all fonts you wanted you can now start the baking process
+    for every selected glyph to image by calling `nk_font_atlas_bake`.
+    The baking process returns image memory, width and height which can be used to
+    either create your own image object or upload it to any graphics library.
+    No matter which case you finally have to call `nk_font_atlas_end` which
+    will free all temporary memory including the font atlas image so make sure
+    you created our texture beforehand. `nk_font_atlas_end` requires a handle
+    to your font texture or object and optionally fills a `struct nk_draw_null_texture`
+    which can be used for the optional vertex output. If you don't want it just
+    set the argument to `NULL`.
+
+    At this point you are done and if you don't want to reuse the font atlas you
+    can call `nk_font_atlas_cleanup` to free all truetype blobs and configuration
+    memory. Finally if you don't use the font atlas and any of it's fonts anymore
+    you need to call `nk_font_atlas_clear` to free all memory still being used.
+
+        struct nk_font_atlas atlas;
+        nk_font_atlas_init_default(&atlas);
+        nk_font_atlas_begin(&atlas);
+        nk_font *font = nk_font_atlas_add_from_file(&atlas, "Path/To/Your/TTF_Font.ttf", 13, 0);
+        nk_font *font2 = nk_font_atlas_add_from_file(&atlas, "Path/To/Your/TTF_Font2.ttf", 16, 0);
+        const void* img = nk_font_atlas_bake(&atlas, &img_width, &img_height, NK_FONT_ATLAS_RGBA32);
+        nk_font_atlas_end(&atlas, nk_handle_id(texture), 0);
+
+        struct nk_context ctx;
+        nk_init_default(&ctx, &font->handle);
+        while (1) {
+
+        }
+        nk_font_atlas_clear(&atlas);
+
+    The font baker API is probably the most complex API inside this library and
+    I would suggest reading some of my examples `example/` to get a grip on how
+    to use the font atlas. There are a number of details I left out. For example
+    how to merge fonts, configure a font with `nk_font_config` to use other languages,
+    use another texture coordinate format and a lot more:
+
+        struct nk_font_config cfg = nk_font_config(font_pixel_height);
+        cfg.merge_mode = nk_false or nk_true;
+        cfg.range = nk_font_korean_glyph_ranges();
+        cfg.coord_type = NK_COORD_PIXEL;
+        nk_font *font = nk_font_atlas_add_from_file(&atlas, "Path/To/Your/TTF_Font.ttf", 13, &cfg);

+ *
+ * ===============================================================*/
+/*  A basic (double)-buffer with linear allocation and resetting as only
+    freeing policy. The buffer's main purpose is to control all memory management
+    inside the GUI toolkit and still leave memory control as much as possible in
+    the hand of the user while also making sure the library is easy to use if
+    not as much control is needed.
+    In general all memory inside this library can be provided from the user in
+    three different ways.
+
+    The first way and the one providing most control is by just passing a fixed
+    size memory block. In this case all control lies in the hand of the user
+    since he can exactly control where the memory comes from and how much memory
+    the library should consume. Of course using the fixed size API removes the
+    ability to automatically resize a buffer if not enough memory is provided so
+    you have to take over the resizing. While being a fixed sized buffer sounds
+    quite limiting, it is very effective in this library since the actual memory
+    consumption is quite stable and has a fixed upper bound for a lot of cases.
+
+    If you don't want to think about how much memory the library should allocate
+    at all time or have a very dynamic UI with unpredictable memory consumption

+    NK_INCLUDE_DEFAULT_ALLOCATOR which uses the standard library memory

+/* Editing text in this library is handled by either `nk_edit_string` or
+ * `nk_edit_buffer`. But like almost everything in this library there are multiple
+ * ways of doing it and a balance between control and ease of use with memory
+ * as well as functionality controlled by flags.
+ *
+ * This library generally allows three different levels of memory control:
+ * First of is the most basic way of just providing a simple char array with
+ * string length. This method is probably the easiest way of handling simple
+ * user text input. Main upside is complete control over memory while the biggest
+ * downside in comparison with the other two approaches is missing undo/redo.
+ *
+ * For UIs that require undo/redo the second way was created. It is based on
+ * a fixed size nk_text_edit struct, which has an internal undo/redo stack.
+ * This is mainly useful if you want something more like a text editor but don't want
+ * to have a dynamically growing buffer.
+ *
+ * The final way is using a dynamically growing nk_text_edit struct, which
+ * has both a default version if you don't care where memory comes from and an
+ * allocator version if you do. While the text editor is quite powerful for its
+ * complexity I would not recommend editing gigabytes of data with it.
+ * It is rather designed for uses cases which make sense for a GUI library not for
+ * an full blown text editor.

+ *
+ * ===============================================================*/
+/*  This library was designed to be render backend agnostic so it does
+    not draw anything to screen. Instead all drawn shapes, widgets
+    are made of, are buffered into memory and make up a command queue.
+    Each frame therefore fills the command buffer with draw commands
+    that then need to be executed by the user and his own render backend.
+    After that the command buffer needs to be cleared and a new frame can be
+    started. It is probably important to note that the command buffer is the main
+    drawing API and the optional vertex buffer API only takes this format and
+    converts it into a hardware accessible format.
+
+    To use the command queue to draw your own widgets you can access the
+    command buffer of each window by calling `nk_window_get_canvas` after
+    previously having called `nk_begin`:
+
+        void draw_red_rectangle_widget(struct nk_context *ctx)
+        {
+            struct nk_command_buffer *canvas;
+            struct nk_input *input = &ctx->input;
+            canvas = nk_window_get_canvas(ctx);
+
+            struct nk_rect space;
+            enum nk_widget_layout_states state;
+            state = nk_widget(&space, ctx);
+            if (!state) return;
+
+            if (state != NK_WIDGET_ROM)
+                update_your_widget_by_user_input(...);
+            nk_fill_rect(canvas, space, 0, nk_rgb(255,0,0));
+        }
+
+        if (nk_begin(...)) {
+            nk_layout_row_dynamic(ctx, 25, 1);
+            draw_red_rectangle_widget(ctx);
+        }
+        nk_end(..)
+
+    Important to know if you want to create your own widgets is the `nk_widget`
+    call. It allocates space on the panel reserved for this widget to be used,
+    but also returns the state of the widget space. If your widget is not seen and does
+    not have to be updated it is '0' and you can just return. If it only has
+    to be drawn the state will be `NK_WIDGET_ROM` otherwise you can do both
+    update and draw your widget. The reason for separating is to only draw and
+    update what is actually necessary which is crucial for performance.

+/*  The optional vertex buffer draw list provides a 2D drawing context
+    with antialiasing functionality which takes basic filled or outlined shapes
+    or a path and outputs vertexes, elements and draw commands.
+    The actual draw list API is not required to be used directly while using this
+    library since converting the default library draw command output is done by
+    just calling `nk_convert` but I decided to still make this library accessible
+    since it can be useful.
+
+    The draw list is based on a path buffering and polygon and polyline
+    rendering API which allows a lot of ways to draw 2D content to screen.
+    In fact it is probably more powerful than needed but allows even more crazy
+    things than this library provides by default.

+/*  Since nuklear is supposed to work on all systems providing floating point
+    math without any dependencies I also had to implement my own math functions
+    for sqrt, sin and cos. Since the actual highly accurate implementations for
+    the standard library functions are quite complex and I do not need high
+    precision for my use cases I use approximations.
+
+    Sqrt
+    ----
+    For square root nuklear uses the famous fast inverse square root:
+    https://en.wikipedia.org/wiki/Fast_inverse_square_root with
+    slightly tweaked magic constant. While on today's hardware it is
+    probably not faster it is still fast and accurate enough for
+    nuklear's use cases. IMPORTANT: this requires float format IEEE 754
+
+    Sine/Cosine
+    -----------
+    All constants inside both function are generated Remez's minimax
+    approximations for value range 0...2*PI. The reason why I decided to
+    approximate exactly that range is that nuklear only needs sine and
+    cosine to generate circles which only requires that exact range.
+    In addition I used Remez instead of Taylor for additional precision:
+    www.lolengine.net/blog/2011/12/21/better-function-approximations.
+
+    The tool I used to generate constants for both sine and cosine
+    (it can actually approximate a lot more functions) can be
+    found here: www.lolengine.net/wiki/oss/lolremez

+            cos(a + b) = cos(a) * cos(b) - sin(a) * sin(b)
+
+        Two coordinates (x, y) of a point on a circle centered on

+            x = r * cos(a)
+            y = r * sin(a)
+        where r is the radius of the circle,
+            a is the angle between (x, y) and the origin.
+
+        This allows us to rotate the coordinates around the
+        origin by an angle b using the following transformation:
+            x' = r * cos(a + b) = x * cos(b) - y * sin(b)

+/// [date][x.yy.zz]-[description]
+/// -[date]: date on which the change has been pushed
+/// -[x.yy.zz]: Numerical version string representation. Each version number on the right
+///             resets back to zero if version on the left is incremented.
+///    - [x]: Major version with API and library breaking changes
+///    - [yy]: Minor version with non-breaking API and library changes
+///    - [zz]: Bug fix version with no direct changes to API
+///
+/// - 2018/04/01 (4.00.1) - Fixed calling `nk_convert` multiple time per single frame
+/// - 2018/04/01 (4.00.0) - BREAKING CHANGE: nk_draw_list_clear no longer tries to
+///                         clear provided buffers. So make sure to either free
+///                         or clear each passed buffer after calling nk_convert.
+/// - 2018/02/23 (3.00.6) - Fixed slider dragging behavior
+/// - 2018/01/31 (3.00.5) - Fixed overcalculation of cursor data in font baking process
+/// - 2018/01/31 (3.00.4) - Removed name collision with stb_truetype
+/// - 2018/01/28 (3.00.3) - Fixed panel window border drawing bug
+/// - 2018/01/12 (3.00.2) - Added `nk_group_begin_titled` for separed group identifier and title
+/// - 2018/01/07 (3.00.1) - Started to change documentation style
+/// - 2018/01/05 (3.00.0) - BREAKING CHANGE: The previous color picker API was broken
+///                        because of conversions between float and byte color representation.
+///                        Color pickers now use floating point values to represent
+///                        HSV values. To get back the old behavior I added some additional
+///                        color conversion functions to cast between nk_color and
+///                        nk_colorf.
+/// - 2017/12/23 (2.00.7) - Fixed small warning
+/// - 2017/12/23 (2.00.7) - Fixed nk_edit_buffer behavior if activated to allow input
+/// - 2017/12/23 (2.00.7) - Fixed modifyable progressbar dragging visuals and input behavior
+/// - 2017/12/04 (2.00.6) - Added formated string tooltip widget
+/// - 2017/11/18 (2.00.5) - Fixed window becoming hidden with flag NK_WINDOW_NO_INPUT
+/// - 2017/11/15 (2.00.4) - Fixed font merging
+/// - 2017/11/07 (2.00.3) - Fixed window size and position modifier functions
+/// - 2017/09/14 (2.00.2) - Fixed nk_edit_buffer and nk_edit_focus behavior
+/// - 2017/09/14 (2.00.1) - Fixed window closing behavior
+/// - 2017/09/14 (2.00.0) - BREAKING CHANGE: Modifing window position and size funtions now
+///                        require the name of the window and must happen outside the window
+///                        building process (between function call nk_begin and nk_end).
+/// - 2017/09/11 (1.40.9) - Fixed window background flag if background window is declared last
+/// - 2017/08/27 (1.40.8) - Fixed `nk_item_is_any_active` for hidden windows
+/// - 2017/08/27 (1.40.7) - Fixed window background flag
+/// - 2017/07/07 (1.40.6) - Fixed missing clipping rect check for hovering/clicked

+///                        and filled rectangles
+/// - 2017/07/07 (1.40.4) - Fixed bug in nk_convert trying to add windows that are in
+///                        process of being destroyed.
+/// - 2017/07/07 (1.40.3) - Fixed table internal bug caused by storing table size in
+///                        window instead of directly in table.
+/// - 2017/06/30 (1.40.2) - Removed unneeded semicolon in C++ NK_ALIGNOF macro
+/// - 2017/06/30 (1.40.1) - Fixed drawing lines smaller or equal zero
+/// - 2017/06/08 (1.40.0) - Removed the breaking part of last commit. Auto layout now only
+///                        comes in effect if you pass in zero was row height argument
+/// - 2017/06/08 (1.40.0) - BREAKING CHANGE: while not directly API breaking it will change
+///                        how layouting works. From now there will be an internal minimum
+///                        row height derived from font height. If you need a row smaller than
+///                        that you can directly set it by `nk_layout_set_min_row_height` and
+///                        reset the value back by calling `nk_layout_reset_min_row_height.
+/// - 2017/06/08 (1.39.1) - Fixed property text edit handling bug caused by past `nk_widget` fix
+/// - 2017/06/08 (1.39.0) - Added function to retrieve window space without calling a nk_layout_xxx function
+/// - 2017/06/06 (1.38.5) - Fixed `nk_convert` return flag for command buffer
+/// - 2017/05/23 (1.38.4) - Fixed activation behavior for widgets partially clipped
+/// - 2017/05/10 (1.38.3) - Fixed wrong min window size mouse scaling over boundries
+/// - 2017/05/09 (1.38.2) - Fixed vertical scrollbar drawing with not enough space
+/// - 2017/05/09 (1.38.1) - Fixed scaler dragging behavior if window size hits minimum size
+/// - 2017/05/06 (1.38.0) - Added platform double-click support

+/// - 2017/03/04 (1.34.1) - Fixed group closable flag
+/// - 2017/02/25 (1.34.0) - Added custom draw command for better language binding support
+/// - 2017/01/24 (1.33.0) - Added programatic way of remove edit focus
+/// - 2017/01/24 (1.32.3) - Fixed wrong define for basic type definitions for windows
+/// - 2017/01/21 (1.32.2) - Fixed input capture from hidden or closed windows
+/// - 2017/01/21 (1.32.1) - Fixed slider behavior and drawing
+/// - 2017/01/13 (1.32.0) - Added flag to put scaler into the bottom left corner
+/// - 2017/01/13 (1.31.0) - Added additional row layouting method to combine both
+///                        dynamic and static widgets.
+/// - 2016/12/31 (1.30.0) - Extended scrollbar offset from 16-bit to 32-bit
+/// - 2016/12/31 (1.29.2)- Fixed closing window bug of minimized windows
+/// - 2016/12/03 (1.29.1)- Fixed wrapped text with no seperator and C89 error
+/// - 2016/12/03 (1.29.0) - Changed text wrapping to process words not characters
+/// - 2016/11/22 (1.28.6)- Fixed window minimized closing bug
+/// - 2016/11/19 (1.28.5)- Fixed abstract combo box closing behavior
+/// - 2016/11/19 (1.28.4)- Fixed tooltip flickering
+/// - 2016/11/19 (1.28.3)- Fixed memory leak caused by popup repeated closing
+/// - 2016/11/18 (1.28.2)- Fixed memory leak caused by popup panel allocation
+/// - 2016/11/10 (1.28.1)- Fixed some warnings and C++ error
+/// - 2016/11/10 (1.28.0)- Added additional `nk_button` versions which allows to directly
+///                        pass in a style struct to change buttons visual.
+/// - 2016/11/10 (1.27.0)- Added additional 'nk_tree' versions to support external state
+///                        storage. Just like last the `nk_group` commit the main
+///                        advantage is that you optionally can minimize nuklears runtime
+///                        memory consumption or handle hash collisions.
+/// - 2016/11/09 (1.26.0)- Added additional `nk_group` version to support external scrollbar
+///                        offset storage. Main advantage is that you can externalize
+///                        the memory management for the offset. It could also be helpful
+///                        if you have a hash collision in `nk_group_begin` but really
+///                        want the name. In addition I added `nk_list_view` which allows
+///                        to draw big lists inside a group without actually having to
+///                        commit the whole list to nuklear (issue #269).
+/// - 2016/10/30 (1.25.1)- Fixed clipping rectangle bug inside `nk_draw_list`
+/// - 2016/10/29 (1.25.0)- Pulled `nk_panel` memory management into nuklear and out of
+///                        the hands of the user. From now on users don't have to care
+///                        about panels unless they care about some information. If you
+///                        still need the panel just call `nk_window_get_panel`.
+/// - 2016/10/21 (1.24.0)- Changed widget border drawing to stroked rectangle from filled
+///                        rectangle for less overdraw and widget background transparency.
+/// - 2016/10/18 (1.23.0)- Added `nk_edit_focus` for manually edit widget focus control
+/// - 2016/09/29 (1.22.7)- Fixed deduction of basic type in non `<stdint.h>` compilation
+/// - 2016/09/29 (1.22.6)- Fixed edit widget UTF-8 text cursor drawing bug
+/// - 2016/09/28 (1.22.5)- Fixed edit widget UTF-8 text appending/inserting/removing
+/// - 2016/09/28 (1.22.4)- Fixed drawing bug inside edit widgets which offset all text
+///                        text in every edit widget if one of them is scrolled.
+/// - 2016/09/28 (1.22.3)- Fixed small bug in edit widgets if not active. The wrong
+///                        text length is passed. It should have been in bytes but
+///                        was passed as glyphes.
+/// - 2016/09/20 (1.22.2)- Fixed color button size calculation
+/// - 2016/09/20 (1.22.1)- Fixed some `nk_vsnprintf` behavior bugs and removed
+///                        `<stdio.h>` again from `NK_INCLUDE_STANDARD_VARARGS`.
+/// - 2016/09/18 (1.22.0)- C89 does not support vsnprintf only C99 and newer as well
+///                        as C++11 and newer. In addition to use vsnprintf you have
+///                        to include <stdio.h>. So just defining `NK_INCLUDE_STD_VAR_ARGS`
+///                        is not enough. That behavior is now fixed. By default if
+///                        both varargs as well as stdio is selected I try to use
+///                        vsnprintf if not possible I will revert to vsprintf. If
+///                        varargs but not stdio was defined I will use my own function.
+/// - 2016/09/15 (1.21.2)- Fixed panel `close` behavior for deeper panel levels
+/// - 2016/09/15 (1.21.1)- Fixed C++ errors and wrong argument to `nk_panel_get_xxxx`
+/// - 2016/09/13 (1.21.0) - !BREAKING! Fixed nonblocking popup behavior in menu, combo,
+///                        and contextual which prevented closing in y-direction if
+///                        popup did not reach max height.
+///                        In addition the height parameter was changed into vec2
+///                        for width and height to have more control over the popup size.
+/// - 2016/09/13 (1.20.3) - Cleaned up and extended type selection
+/// - 2016/09/13 (1.20.2)- Fixed slider behavior hopefully for the last time. This time
+///                        all calculation are correct so no more hackery.
+/// - 2016/09/13 (1.20.1)- Internal change to divide window/panel flags into panel flags and types.
+///                        Suprisinly spend years in C and still happened to confuse types
+///                        with flags. Probably something to take note.
+/// - 2016/09/08 (1.20.0)- Added additional helper function to make it easier to just
+///                        take the produced buffers from `nk_convert` and unplug the
+///                        iteration process from `nk_context`. So now you can
+///                        just use the vertex,element and command buffer + two pointer
+///                        inside the command buffer retrieved by calls `nk__draw_begin`
+///                        and `nk__draw_end` and macro `nk_draw_foreach_bounded`.
+/// - 2016/09/08 (1.19.0)- Added additional asserts to make sure every `nk_xxx_begin` call
+///                        for windows, popups, combobox, menu and contextual is guarded by
+///                        `if` condition and does not produce false drawing output.
+/// - 2016/09/08 (1.18.0)- Changed confusing name for `NK_SYMBOL_RECT_FILLED`, `NK_SYMBOL_RECT`
+///                        to hopefully easier to understand `NK_SYMBOL_RECT_FILLED` and
+///                        `NK_SYMBOL_RECT_OUTLINE`.
+/// - 2016/09/08 (1.17.0)- Changed confusing name for `NK_SYMBOL_CIRLCE_FILLED`, `NK_SYMBOL_CIRCLE`
+///                        to hopefully easier to understand `NK_SYMBOL_CIRCLE_FILLED` and
+///                        `NK_SYMBOL_CIRCLE_OUTLINE`.
+/// - 2016/09/08 (1.16.0)- Added additional checks to select correct types if `NK_INCLUDE_FIXED_TYPES`
+///                        is not defined by supporting the biggest compiler GCC, clang and MSVC.
+/// - 2016/09/07 (1.15.3)- Fixed `NK_INCLUDE_COMMAND_USERDATA` define to not cause an error
+/// - 2016/09/04 (1.15.2)- Fixed wrong combobox height calculation
+/// - 2016/09/03 (1.15.1)- Fixed gaps inside combo boxes in OpenGL
+/// - 2016/09/02 (1.15.0) - Changed nuklear to not have any default vertex layout and
+///                        instead made it user provided. The range of types to convert
+///                        to is quite limited at the moment, but I would be more than
+///                        happy to accept PRs to add additional.
+/// - 2016/08/30 (1.14.2) - Removed unused variables
+/// - 2016/08/30 (1.14.1) - Fixed C++ build errors
+/// - 2016/08/30 (1.14.0) - Removed mouse dragging from SDL demo since it does not work correctly
+/// - 2016/08/30 (1.13.4) - Tweaked some default styling variables
+/// - 2016/08/30 (1.13.3) - Hopefully fixed drawing bug in slider, in general I would
+///                        refrain from using slider with a big number of steps.
+/// - 2016/08/30 (1.13.2) - Fixed close and minimize button which would fire even if the
+///                        window was in Read Only Mode.
+/// - 2016/08/30 (1.13.1) - Fixed popup panel padding handling which was previously just
+///                        a hack for combo box and menu.
+/// - 2016/08/30 (1.13.0) - Removed `NK_WINDOW_DYNAMIC` flag from public API since
+///                        it is bugged and causes issues in window selection.
+/// - 2016/08/30 (1.12.0) - Removed scaler size. The size of the scaler is now
+///                        determined by the scrollbar size
+/// - 2016/08/30 (1.11.2) - Fixed some drawing bugs caused by changes from 1.11
+/// - 2016/08/30 (1.11.1) - Fixed overlapping minimized window selection
+/// - 2016/08/30 (1.11.0) - Removed some internal complexity and overly complex code
+///                        handling panel padding and panel border.
+/// - 2016/08/29 (1.10.0) - Added additional height parameter to `nk_combobox_xxx`
+/// - 2016/08/29 (1.10.0) - Fixed drawing bug in dynamic popups
+/// - 2016/08/29 (1.10.0) - Added experimental mouse scrolling to popups, menus and comboboxes
+/// - 2016/08/26 (1.10.0) - Added window name string prepresentation to account for
+///                        hash collisions. Currently limited to NK_WINDOW_MAX_NAME
+///                        which in term can be redefined if not big enough.
+/// - 2016/08/26 (1.10.0) - Added stacks for temporary style/UI changes in code
+/// - 2016/08/25 (1.10.0) - Changed `nk_input_is_key_pressed` and 'nk_input_is_key_released'
+///                        to account for key press and release happening in one frame.
+/// - 2016/08/25 (1.10.0) - Added additional nk_edit flag to directly jump to the end on activate
+/// - 2016/08/17 (1.09.6)- Removed invalid check for value zero in nk_propertyx
+/// - 2016/08/16 (1.09.5)- Fixed ROM mode for deeper levels of popup windows parents.
+/// - 2016/08/15 (1.09.4)- Editbox are now still active if enter was pressed with flag
+///                        `NK_EDIT_SIG_ENTER`. Main reasoning is to be able to keep
+///                        typing after commiting.
+/// - 2016/08/15 (1.09.4)- Removed redundant code
+/// - 2016/08/15 (1.09.4)- Fixed negative numbers in `nk_strtoi` and remove unused variable
+/// - 2016/08/15 (1.09.3)- Fixed `NK_WINDOW_BACKGROUND` flag behavior to select a background
+///                        window only as selected by hovering and not by clicking.
+/// - 2016/08/14 (1.09.2)- Fixed a bug in font atlas which caused wrong loading
+///                        of glyphes for font with multiple ranges.
+/// - 2016/08/12 (1.09.1)- Added additional function to check if window is currently
+///                        hidden and therefore not visible.
+/// - 2016/08/12 (1.09.1)- nk_window_is_closed now queries the correct flag `NK_WINDOW_CLOSED`
+///                        instead of the old flag `NK_WINDOW_HIDDEN`
+/// - 2016/08/09 (1.09.0) - Added additional double version to nk_property and changed
+///                        the underlying implementation to not cast to float and instead
+///                        work directly on the given values.
+/// - 2016/08/09 (1.08.0) - Added additional define to overwrite library internal
+///                        floating pointer number to string conversion for additional
+///                        precision.
+/// - 2016/08/09 (1.08.0) - Added additional define to overwrite library internal
+///                        string to floating point number conversion for additional
+///                        precision.
+/// - 2016/08/08 (1.07.2)- Fixed compiling error without define NK_INCLUDE_FIXED_TYPE
+/// - 2016/08/08 (1.07.1)- Fixed possible floating point error inside `nk_widget` leading
+///                        to wrong wiget width calculation which results in widgets falsly
+///                        becomming tagged as not inside window and cannot be accessed.
+/// - 2016/08/08 (1.07.0) - Nuklear now differentiates between hiding a window (NK_WINDOW_HIDDEN) and
+///                        closing a window (NK_WINDOW_CLOSED). A window can be hidden/shown
+///                        by using `nk_window_show` and closed by either clicking the close
+///                        icon in a window or by calling `nk_window_close`. Only closed
+///                        windows get removed at the end of the frame while hidden windows
+///                        remain.
+/// - 2016/08/08 (1.06.0) - Added `nk_edit_string_zero_terminated` as a second option to
+///                        `nk_edit_string` which takes, edits and outputs a '\0' terminated string.
+/// - 2016/08/08 (1.05.4)- Fixed scrollbar auto hiding behavior
+/// - 2016/08/08 (1.05.3)- Fixed wrong panel padding selection in `nk_layout_widget_space`
+/// - 2016/08/07 (1.05.2)- Fixed old bug in dynamic immediate mode layout API, calculating
+///                        wrong item spacing and panel width.
+///- 2016/08/07 (1.05.1)- Hopefully finally fixed combobox popup drawing bug
+///- 2016/08/07 (1.05.0) - Split varargs away from NK_INCLUDE_STANDARD_IO into own
+///                        define NK_INCLUDE_STANDARD_VARARGS to allow more fine
+///                        grained controlled over library includes.
+/// - 2016/08/06 (1.04.5)- Changed memset calls to NK_MEMSET
+/// - 2016/08/04 (1.04.4)- Fixed fast window scaling behavior
+/// - 2016/08/04 (1.04.3)- Fixed window scaling, movement bug which appears if you
+///                        move/scale a window and another window is behind it.
+///                        If you are fast enough then the window behind gets activated
+///                        and the operation is blocked. I now require activating
+///                        by hovering only if mouse is not pressed.
+/// - 2016/08/04 (1.04.2)- Fixed changing fonts
+/// - 2016/08/03 (1.04.1)- Fixed `NK_WINDOW_BACKGROUND` behavior
+/// - 2016/08/03 (1.04.0) - Added color parameter to `nk_draw_image`
+/// - 2016/08/03 (1.04.0) - Added additional window padding style attributes for
+///                        sub windows (combo, menu, ...)
+/// - 2016/08/03 (1.04.0) - Added functions to show/hide software cursor
+/// - 2016/08/03 (1.04.0) - Added `NK_WINDOW_BACKGROUND` flag to force a window
+///                        to be always in the background of the screen
+/// - 2016/08/03 (1.03.2)- Removed invalid assert macro for NK_RGB color picker
+/// - 2016/08/01 (1.03.1)- Added helper macros into header include guard
+/// - 2016/07/29 (1.03.0) - Moved the window/table pool into the header part to
+///                        simplify memory management by removing the need to
+///                        allocate the pool.
+/// - 2016/07/29 (1.02.0) - Added auto scrollbar hiding window flag which if enabled
+///                        will hide the window scrollbar after NK_SCROLLBAR_HIDING_TIMEOUT
+///                        seconds without window interaction. To make it work
+///                        you have to also set a delta time inside the `nk_context`.
+/// - 2016/07/25 (1.01.1) - Fixed small panel and panel border drawing bugs
+/// - 2016/07/15 (1.01.0) - Added software cursor to `nk_style` and `nk_context`
+/// - 2016/07/15 (1.01.0) - Added const correctness to `nk_buffer_push' data argument
+/// - 2016/07/15 (1.01.0) - Removed internal font baking API and simplified
+///                        font atlas memory management by converting pointer
+///                        arrays for fonts and font configurations to lists.
+/// - 2016/07/15 (1.00.0) - Changed button API to use context dependend button
+///                        behavior instead of passing it for every function call.

+/* stb_image_write - v1.02 - public domain - http://nothings.org/stb/stb_image_write.h
+   writes out PNG/BMP/TGA images to C stdio - Sean Barrett 2010-2015
+                                     no warranty implied; use at your own risk
+
+   Before #including,
+
+       #define STB_IMAGE_WRITE_IMPLEMENTATION
+
+   in the file that you want to have the implementation.
+
+   Will probably not work correctly with strict-aliasing optimizations.
+
+ABOUT:
+
+   This header file is a library for writing images to C stdio. It could be
+   adapted to write to memory or a general streaming interface; let me know.
+
+   The PNG output is not optimal; it is 20-50% larger than the file
+   written by a decent optimizing implementation. This library is designed
+   for source code compactness and simplicity, not optimal image file size
+   or run-time performance.
+
+BUILDING:
+
+   You can #define STBIW_ASSERT(x) before the #include to avoid using assert.h.
+   You can #define STBIW_MALLOC(), STBIW_REALLOC(), and STBIW_FREE() to replace
+   malloc,realloc,free.
+   You can define STBIW_MEMMOVE() to replace memmove()
+
+USAGE:
+
+   There are four functions, one for each image file format:
+
+     int stbi_write_png(char const *filename, int w, int h, int comp, const void *data, int stride_in_bytes);
+     int stbi_write_bmp(char const *filename, int w, int h, int comp, const void *data);
+     int stbi_write_tga(char const *filename, int w, int h, int comp, const void *data);
+     int stbi_write_hdr(char const *filename, int w, int h, int comp, const float *data);
+
+   There are also four equivalent functions that use an arbitrary write function. You are
+   expected to open/close your file-equivalent before and after calling these:

+
+   where the callback is:
+      void stbi_write_func(void *context, void *data, int size);
+
+   You can define STBI_WRITE_NO_STDIO to disable the file variant of these
+   functions, so the library will not use stdio.h at all. However, this will
+   also disable HDR writing, because it requires stdio for formatted output.
+
+   Each function returns 0 on failure and non-0 on success.
+
+   The functions create an image file defined by the parameters. The image
+   is a rectangle of pixels stored from left-to-right, top-to-bottom.
+   Each pixel contains 'comp' channels of data stored interleaved with 8-bits
+   per channel, in the following order: 1=Y, 2=YA, 3=RGB, 4=RGBA. (Y is
+   monochrome color.) The rectangle is 'w' pixels wide and 'h' pixels tall.
+   The *data pointer points to the first byte of the top-left-most pixel.
+   For PNG, "stride_in_bytes" is the distance in bytes from the first byte of
+   a row of pixels to the first byte of the next row of pixels.
+
+   PNG creates output files with the same number of components as the input.
+   The BMP format expands Y to RGB in the file format and does not
+   output alpha.
+
+   PNG supports writing rectangles of data even when the bytes storing rows of
+   data are not consecutive in memory (e.g. sub-rectangles of a larger image),
+   by supplying the stride between the beginning of adjacent rows. The other
+   formats do not. (Thus you cannot write a native-format BMP through the BMP
+   writer, both because it is in BGR order and because it may have padding
+   at the end of the line.)
+
+   HDR expects linear float data. Since the format is always 32-bit rgb(e)
+   data, alpha (if provided) is discarded, and for monochrome data it is
+   replicated across all three channels.
+
+   TGA supports RLE or non-RLE compressed data. To use non-RLE-compressed
+   data, set the global variable 'stbi_write_tga_with_rle' to 0.

+* @mainpage TinyCThread API Reference
+*
+* @section intro_sec Introduction
+* TinyCThread is a minimal, portable implementation of basic threading
+* classes for C.
+*
+* They closely mimic the functionality and naming of the C11 standard, and
+* should be easily replaceable with the corresponding standard variants.
+*
+* @section port_sec Portability
+* The Win32 variant uses the native Win32 API for implementing the thread
+* classes, while for other systems, the POSIX threads API (pthread) is used.
+*
+* @section misc_sec Miscellaneous
+* The following special keywords are available: #_Thread_local.
+*
+* For more detailed information, browse the different sections of this
+* documentation. A good place to start is:
+* tinycthread.h.

+## Asking a question
+
+Questions about how to use GLFW should be asked either in the [support
+section](https://discourse.glfw.org/c/support) of the forum, under the [Stack
+Overflow tag](https://stackoverflow.com/questions/tagged/glfw) or [Game
+Development tag](https://gamedev.stackexchange.com/questions/tagged/glfw) on
+Stack Exchange or in the IRC channel `#glfw` on
+[Freenode](http://freenode.net/).
+
+Questions about the design or implementation of GLFW or about future plans
+should be asked in the [dev section](https://discourse.glfw.org/c/dev) of the
+forum or in the IRC channel.  Please don't open a GitHub issue to discuss design
+questions without first checking with a maintainer.
+
+
+## Reporting a bug
+
+If GLFW is behaving unexpectedly at run-time, start by setting an [error
+callback](https://www.glfw.org/docs/latest/intro_guide.html#error_handling).
+GLFW will often tell you the cause of an error via this callback.  If it
+doesn't, that might be a separate bug.
+
+If GLFW is crashing or triggering asserts, make sure that all your object
+handles and other pointers are valid.
+
+For bugs where it makes sense, a short, self contained example is absolutely
+invaluable.  Just put it inline in the body text.  Note that if the bug is
+reproducible with one of the test programs that come with GLFW, just mention
+that instead.
+
+__Don't worry about adding too much information__.  Unimportant information can
+be abbreviated or removed later, but missing information can stall bug fixing,
+especially when your schedule doesn't align with that of the maintainer.
+
+__Please provide text as text, not as images__.  This includes code, error
+messages and any other text.  Text in images cannot be found by other users
+searching for the same problem and may have to be re-typed by maintainers when
+debugging.
+
+You don't need to manually indent your code or other text to quote it with
+GitHub Markdown; just surround it with triple backticks:
+
+    ```
+    Some quoted text.
+    ```
+
+You can also add syntax highlighting by appending the common file extension:
+
+    ```c
+    int five(void)
+    {
+        return 5;
+    }
+    ```
+
+There are issue labels for both platforms and GPU manufacturers, so there is no
+need to mention these in the subject line.  If you do, it will be removed when
+the issue is labeled.
+
+If your bug is already reported, please add any new information you have, or if
+it already has everything, give it a :+1:.
+
+
+### Reporting a compile or link bug
+
+__Note:__ GLFW needs many system APIs to do its job, which on some platforms
+means linking to many system libraries.  If you are using GLFW as a static
+library, that means your application needs to link to these in addition to GLFW.
+
+__Note:__ Check the [Compiling
+GLFW](https://www.glfw.org/docs/latest/compile.html) guide and or [Building
+applications](https://www.glfw.org/docs/latest/build.html) guide for before
+opening an issue of this kind.  Most issues are caused by a missing package or
+linker flag.
+
+Always include the __operating system name and version__ (e.g. `Windows
+7 64-bit` or `Ubuntu 15.10`) and the __compiler name and version__ (e.g. `Visual
+C++ 2015 Update 2`).  If you are using an official release of GLFW,
+include the __GLFW release version__ (e.g. `3.1.2`), otherwise include the
+__GLFW commit ID__ (e.g.  `3795d78b14ef06008889cc422a1fb8d642597751`) from Git.
+
+Please also include the __complete build log__ from your compiler and linker,
+even if it's long.  It can always be shortened later, if necessary.
+
+
+#### Quick template
+
+```
+OS and version:
+Compiler version:
+Release or commit:
+Build log:
+```
+
+
+### Reporting a segfault or other crash bug
+
+Always include the __operating system name and version__ (e.g. `Windows
+7 64-bit` or `Ubuntu 15.10`).  If you are using an official release of GLFW,
+include the __GLFW release version__ (e.g. `3.1.2`), otherwise include the
+__GLFW commit ID__ (e.g.  `3795d78b14ef06008889cc422a1fb8d642597751`) from Git.
+
+Please also include any __error messages__ provided to your application via the
+[error
+callback](https://www.glfw.org/docs/latest/intro_guide.html#error_handling) and
+the __full call stack__ of the crash, or if the crash does not occur in debug
+mode, mention that instead.

+
+### Reporting a context creation bug
+
+__Note:__ Windows ships with graphics drivers that do not support OpenGL.  If
+GLFW says that your machine lacks support for OpenGL, it very likely does.
+Install drivers from the computer manufacturer or graphics card manufacturer
+([Nvidia](https://www.geforce.com/drivers),
+[AMD](https://www.amd.com/en/support),
+[Intel](https://www-ssl.intel.com/content/www/us/en/support/detect.html)) to
+fix this.
+
+__Note:__ AMD only supports OpenGL ES on Windows via EGL.  See the
+[GLFW\_CONTEXT\_CREATION\_API](https://www.glfw.org/docs/latest/window_guide.html#window_hints_ctx)
+hint for how to select EGL.
+
+Please verify that context creation also fails with the `glfwinfo` tool before
+reporting it as a bug.  This tool is included in the GLFW source tree as
+`tests/glfwinfo.c` and is built along with the library.  It has switches for all
+GLFW context and framebuffer hints.  Run `glfwinfo -h` for a complete list.
+
+Always include the __operating system name and version__ (e.g. `Windows
+7 64-bit` or `Ubuntu 15.10`).  If you are using an official release of GLFW,
+include the __GLFW release version__ (e.g. `3.1.2`), otherwise include the
+__GLFW commit ID__ (e.g.  `3795d78b14ef06008889cc422a1fb8d642597751`) from Git.
+
+If you are running your program in a virtual machine, please mention this and
+include the __VM name and version__ (e.g. `VirtualBox 5.1`).
+
+Please also include the __GLFW version string__ (`3.2.0 X11 EGL clock_gettime
+/dev/js`), as described
+[here](https://www.glfw.org/docs/latest/intro.html#intro_version_string), the
+__GPU model and driver version__ (e.g. `GeForce GTX660 with 352.79`), and the
+__output of `glfwinfo`__ (with switches matching any hints you set in your
+code) when reporting this kind of bug.  If this tool doesn't run on the machine,
+mention that instead.
+
+
+#### Quick template

+
+
+### Reporting a monitor or video mode bug
+
+__Note:__ On headless systems on some platforms, no monitors are reported.  This
+causes glfwGetPrimaryMonitor to return `NULL`, which not all applications are
+prepared for.
+
+__Note:__ Some third-party tools report more video modes than are approved of
+by the OS.  For safety and compatibility, GLFW only reports video modes the OS
+wants programs to use.  This is not a bug.
+
+The `monitors` tool is included in the GLFW source tree as `tests/monitors.c`
+and is built along with the library.  It lists all information GLFW provides
+about monitors it detects.
+
+Always include the __operating system name and version__ (e.g. `Windows
+7 64-bit` or `Ubuntu 15.10`).  If you are using an official release of GLFW,
+include the __GLFW release version__ (e.g. `3.1.2`), otherwise include the
+__GLFW commit ID__ (e.g.  `3795d78b14ef06008889cc422a1fb8d642597751`) from Git.
+
+If you are running your program in a virtual machine, please mention this and
+include the __VM name and version__ (e.g. `VirtualBox 5.1`).
+
+Please also include any __error messages__ provided to your application via the
+[error
+callback](https://www.glfw.org/docs/latest/intro_guide.html#error_handling) and

+### Reporting a window, input or event bug
+
+__Note:__ The exact ordering of related window events will sometimes differ.
+
+__Note:__ Window moving and resizing (by the user) will block the main thread on
+some platforms.  This is not a bug.  Set a [refresh
+callback](https://www.glfw.org/docs/latest/window.html#window_refresh) if you
+want to keep the window contents updated during a move or size operation.
+
+The `events` tool is included in the GLFW source tree as `tests/events.c` and is
+built along with the library.  It prints all information provided to every
+callback supported by GLFW as events occur.  Each event is listed with the time
+and a unique number to make discussions about event logs easier.  The tool has
+command-line options for creating multiple windows and full screen windows.
+
+Always include the __operating system name and version__ (e.g. `Windows
+7 64-bit` or `Ubuntu 15.10`).  If you are using an official release of GLFW,
+include the __GLFW release version__ (e.g. `3.1.2`), otherwise include the

+### Reporting a documentation bug
+
+If you found a bug in the documentation, including this file, then it's fine to
+just link to that web page or mention that source file.  You don't need to match
+the source to the output or vice versa.
+
+
+### Reporting a website bug
+
+If the bug is in the documentation (anything under `/docs/`) then please see the
+section above.  Bugs in the rest of the site are reported to the [website
+source repository](https://github.com/glfw/website/issues).
+
+
+## Requesting a feature
+
+Please explain why you need the feature and how you intend to use it.  If you
+have a specific API design in mind, please add that as well.  If you have or are
+planning to write code for the feature, see the section below.
+
+If there already is a request for the feature you need, add your specific use
+case unless it is already mentioned.  If it is, give it a :+1:.
+
+
+## Contributing a bug fix
+
+__Note:__ You must have all necessary [intellectual
+property rights](https://en.wikipedia.org/wiki/Intellectual_property) to any
+code you contribute.  If you did not write the code yourself, you must explain
+where it came from and under what license you received it.  Even code using the
+same license as GLFW may not be copied without attribution.
+
+__There is no preferred patch size__.  A one character fix is just as welcome as
+a thousand line one, if that is the appropriate size for the fix.
+
+In addition to the code, a complete bug fix includes:
+
+- Change log entry in `README.md`, describing the incorrect behavior
+- Credits entries for all authors of the bug fix
+
+Bug fixes will not be rejected because they don't include all the above parts,
+but please keep in mind that maintainer time is finite and that there are many
+other bugs and features to work on.
+
+If the patch fixes a bug introduced after the last release, it should not get
+a change log entry.
+
+If you haven't already, read the excellent article [How to Write a Git Commit
+Message](https://chris.beams.io/posts/git-commit/).

+## Contributing a feature
+
+__Note:__ You must have all necessary rights to any code you contribute.  If you
+did not write the code yourself, you must explain where it came from and under
+what license.  Even code using the same license as GLFW may not be copied
+without attribution.
+
+__Note:__ If you haven't already implemented the feature, check first if there
+already is an open issue for it and if it's already being developed in an
+[experimental branch](https://github.com/glfw/glfw/branches/all).
+
+__There is no preferred patch size__.  A one character change is just as welcome
+as one adding a thousand line one, if that is the appropriate size for the
+feature.
+
+In addition to the code, a complete feature includes:
+
+- Change log entry in `README.md`, listing all new symbols
+- News page entry, briefly describing the feature
+- Guide documentation, with minimal examples, in the relevant guide
+- Reference documentation, with all applicable tags
+- Cross-references and mentions in appropriate places
+- Credits entries for all authors of the feature
+
+If the feature requires platform-specific code, at minimum stubs must be added
+for the new platform function to all supported and experimental platforms.
+
+If it adds a new callback, support for it must be added to `tests/event.c`.
+
+If it adds a new monitor property, support for it must be added to
+`tests/monitor.c`.
+
+If it adds a new OpenGL, OpenGL ES or Vulkan option or extension, support
+for it must be added to `tests/glfwinfo.c` and the behavior of the library when
+the extension is missing documented in `docs/compat.dox`.
+
+If you haven't already, read the excellent article [How to Write a Git Commit
+Message](https://chris.beams.io/posts/git-commit/).
+
+Features will not be rejected because they don't include all the above parts,
+but please keep in mind that maintainer time is finite and that there are many
+other features and bugs to work on.
+
+Please also keep in mind that any part of the public API that has been included
+in a release cannot be changed until the next _major_ version.  Features can be
+added and existing parts can sometimes be overloaded (in the general sense of
+doing more things, not in the C++ sense), but code written to the API of one
+minor release should both compile and run on subsequent minor releases.

+
+@page build_guide Building applications
+
+@tableofcontents
+
+This is about compiling and linking applications that use GLFW.  For information on
+how to write such applications, start with the
+[introductory tutorial](@ref quick_guide).  For information on how to compile
+the GLFW library itself, see @ref compile_guide.
+
+This is not a tutorial on compilation or linking.  It assumes basic
+understanding of how to compile and link a C program as well as how to use the
+specific compiler of your chosen development environment.  The compilation
+and linking process should be explained in your C programming material and in
+the documentation for your development environment.
+
+
+@section build_include Including the GLFW header file
+
+You should include the GLFW header in the source files where you use OpenGL or
+GLFW.
+
+@code
+#include <GLFW/glfw3.h>
+@endcode
+
+This header declares the GLFW API and by default also includes the OpenGL header
+from your development environment.  See below for how to control this.
+
+The GLFW header also defines any platform-specific macros needed by your OpenGL
+header, so it can be included without needing any window system headers.
+
+For example, under Windows you are normally required to include `windows.h`
+before the OpenGL header, which would bring in the whole Win32 API.  The GLFW
+header duplicates the small number of macros needed.
+
+It does this only when needed, so if `windows.h` _is_ included, the GLFW header
+does not try to redefine those symbols.  The reverse is not true, i.e.
+`windows.h` cannot cope if any of its symbols have already been defined.
+
+In other words:
+
+ - Do _not_ include the OpenGL headers yourself, as GLFW does this for you
+ - Do _not_ include `windows.h` or other platform-specific headers unless you
+   plan on using those APIs directly
+ - If you _do_ need to include such headers, do it _before_ including
+   the GLFW header and it will handle this
+
+If you are using an OpenGL extension loading library such as
+[glad](https://github.com/Dav1dde/glad), the extension loader header should
+be included _before_ the GLFW one.
+
+@code
+#include <glad/gl.h>
+#include <GLFW/glfw3.h>
+@endcode
+
+Alternatively the @ref GLFW_INCLUDE_NONE macro (described below) can be used to
+prevent the GLFW header from including the OpenGL header.
+
+@code
+#define GLFW_INCLUDE_NONE
+#include <GLFW/glfw3.h>
+#include <glad/gl.h>
+@endcode
+
+
+@subsection build_macros GLFW header option macros
+
+These macros may be defined before the inclusion of the GLFW header and affect
+its behavior.
+
+@anchor GLFW_DLL
+__GLFW_DLL__ is required on Windows when using the GLFW DLL, to tell the
+compiler that the GLFW functions are defined in a DLL.
+
+The following macros control which OpenGL or OpenGL ES API header is included.
+Only one of these may be defined at a time.
+
+@note GLFW does not provide any of the API headers mentioned below.  They are
+provided by your development environment or your OpenGL, OpenGL ES or Vulkan
+SDK, and most of them can be downloaded from the
+[Khronos Registry](https://www.khronos.org/registry/).
+
+@anchor GLFW_INCLUDE_GLCOREARB
+__GLFW_INCLUDE_GLCOREARB__ makes the GLFW header include the modern
+`GL/glcorearb.h` header (`OpenGL/gl3.h` on macOS) instead of the regular OpenGL
+header.
+
+@anchor GLFW_INCLUDE_ES1
+__GLFW_INCLUDE_ES1__ makes the GLFW header include the OpenGL ES 1.x `GLES/gl.h`
+header instead of the regular OpenGL header.
+
+@anchor GLFW_INCLUDE_ES2
+__GLFW_INCLUDE_ES2__ makes the GLFW header include the OpenGL ES 2.0
+`GLES2/gl2.h` header instead of the regular OpenGL header.
+
+@anchor GLFW_INCLUDE_ES3
+__GLFW_INCLUDE_ES3__ makes the GLFW header include the OpenGL ES 3.0
+`GLES3/gl3.h` header instead of the regular OpenGL header.
+
+@anchor GLFW_INCLUDE_ES31
+__GLFW_INCLUDE_ES31__ makes the GLFW header include the OpenGL ES 3.1
+`GLES3/gl31.h` header instead of the regular OpenGL header.
+
+@anchor GLFW_INCLUDE_ES32
+__GLFW_INCLUDE_ES31__ makes the GLFW header include the OpenGL ES 3.2
+`GLES3/gl32.h` header instead of the regular OpenGL header.
+
+@anchor GLFW_INCLUDE_NONE
+__GLFW_INCLUDE_NONE__ makes the GLFW header not include any OpenGL or OpenGL ES
+API header.  This is useful in combination with an extension loading library.
+
+If none of the above inclusion macros are defined, the standard OpenGL `GL/gl.h`
+header (`OpenGL/gl.h` on macOS) is included.
+
+The following macros control the inclusion of additional API headers.  Any
+number of these may be defined simultaneously, and/or together with one of the
+above macros.
+
+@anchor GLFW_INCLUDE_VULKAN
+__GLFW_INCLUDE_VULKAN__ makes the GLFW header include the Vulkan
+`vulkan/vulkan.h` header in addition to any selected OpenGL or OpenGL ES header.
+
+@anchor GLFW_INCLUDE_GLEXT
+__GLFW_INCLUDE_GLEXT__ makes the GLFW header include the appropriate extension
+header for the OpenGL or OpenGL ES header selected above after and in addition
+to that header.
+
+@anchor GLFW_INCLUDE_GLU
+__GLFW_INCLUDE_GLU__ makes the header include the GLU header in addition to the
+header selected above.  This should only be used with the standard OpenGL header
+and only for compatibility with legacy code.  GLU has been deprecated and should
+not be used in new code.
+
+@note None of these macros may be defined during the compilation of GLFW itself.
+If your build includes GLFW and you define any these in your build files, make
+sure they are not applied to the GLFW sources.
+
+
+@section build_link Link with the right libraries
+
+GLFW is essentially a wrapper of various platform-specific APIs and therefore
+needs to link against many different system libraries.  If you are using GLFW as
+a shared library / dynamic library / DLL then it takes care of these links.
+However, if you are using GLFW as a static library then your executable will
+need to link against these libraries.
+
+On Windows and macOS, the list of system libraries is static and can be
+hard-coded into your build environment.  See the section for your development
+environment below.  On Linux and other Unix-like operating systems, the list
+varies but can be retrieved in various ways as described below.
+
+A good general introduction to linking is
+[Beginner's Guide to Linkers](https://www.lurklurk.org/linkers/linkers.html) by
+David Drysdale.
+
+
+@subsection build_link_win32 With MinGW or Visual C++ on Windows
+
+The static version of the GLFW library is named `glfw3`.  When using this
+version, it is also necessary to link with some libraries that GLFW uses.
+
+When using MinGW to link an application with the static version of GLFW, you
+must also explicitly link with `gdi32`. Other toolchains including MinGW-w64
+include it in the set of default libraries along with other dependencies like
+`user32` and `kernel32`.
+
+The link library for the GLFW DLL is named `glfw3dll`.  When compiling an
+application that uses the DLL version of GLFW, you need to define the @ref
+GLFW_DLL macro _before_ any inclusion of the GLFW header.  This can be done
+either with a compiler switch or by defining it in your source code.
+
+
+@subsection build_link_cmake_source With CMake and GLFW source
+
+This section is about using CMake to compile and link GLFW along with your
+application.  If you want to use an installed binary instead, see @ref
+build_link_cmake_package.
+
+With a few changes to your `CMakeLists.txt` you can have the GLFW source tree
+built along with your application.
+
+When including GLFW as part of your build, you probably don't want to build the
+GLFW tests, examples and documentation.  To disable these, set the corresponding
+cache variables before adding the GLFW source tree.
+
+@code
+set(GLFW_BUILD_DOCS OFF CACHE BOOL "" FORCE)
+set(GLFW_BUILD_TESTS OFF CACHE BOOL "" FORCE)
+set(GLFW_BUILD_EXAMPLES OFF CACHE BOOL "" FORCE)
+@endcode
+
+Add the root directory of the GLFW source tree to your project.  This will add
+the `glfw` target to your project.
+
+@code{.cmake}
+add_subdirectory(path/to/glfw)
+@endcode
+
+Once GLFW has been added, link your application against the `glfw` target.
+This adds the GLFW library and its link-time dependencies as it is currently
+configured, the include directory for the GLFW header and, when applicable, the
+@ref GLFW_DLL macro.
+
+@code{.cmake}
+target_link_libraries(myapp glfw)
+@endcode
+
+Note that the `glfw` target does not depend on OpenGL, as GLFW loads any OpenGL,
+OpenGL ES or Vulkan libraries it needs at runtime.  If your application calls
+OpenGL directly, instead of using a modern
+[extension loader library](@ref context_glext_auto), use the OpenGL CMake
+package.
+
+@code{.cmake}
+find_package(OpenGL REQUIRED)
+@endcode
+
+If OpenGL is found, the `OpenGL::GL` target is added to your project, containing
+library and include directory paths.  Link against this like above.
+
+@code{.cmake}
+target_link_libraries(myapp OpenGL::GL)
+@endcode
+
+
+@subsection build_link_cmake_package With CMake and installed GLFW binaries
+
+This section is about using CMake to link GLFW after it has been built and
+installed.  If you want to build it along with your application instead, see
+@ref build_link_cmake_source.
+
+With a few changes to your `CMakeLists.txt` you can locate the package and
+target files generated when GLFW is installed.
+
+@code{.cmake}
+find_package(glfw3 3.3 REQUIRED)
+@endcode
+
+Once GLFW has been added to the project, link against it with the `glfw` target.
+This adds the GLFW library and its link-time dependencies, the include directory
+for the GLFW header and, when applicable, the @ref GLFW_DLL macro.
+
+@code{.cmake}
+target_link_libraries(myapp glfw)
+@endcode
+
+Note that the `glfw` target does not depend on OpenGL, as GLFW loads any OpenGL,
+OpenGL ES or Vulkan libraries it needs at runtime.  If your application calls
+OpenGL directly, instead of using a modern
+[extension loader library](@ref context_glext_auto), use the OpenGL CMake
+package.
+
+@code{.cmake}
+find_package(OpenGL REQUIRED)
+@endcode
+
+If OpenGL is found, the `OpenGL::GL` target is added to your project, containing
+library and include directory paths.  Link against this like above.
+
+@code{.cmake}
+target_link_libraries(myapp OpenGL::GL)
+@endcode
+
+
+@subsection build_link_pkgconfig With makefiles and pkg-config on Unix
+
+GLFW supports [pkg-config](https://www.freedesktop.org/wiki/Software/pkg-config/),
+and the `glfw3.pc` pkg-config file is generated when the GLFW library is built
+and is installed along with it.  A pkg-config file describes all necessary
+compile-time and link-time flags and dependencies needed to use a library.  When
+they are updated or if they differ between systems, you will get the correct
+ones automatically.
+
+A typical compile and link command-line when using the static version of the
+GLFW library may look like this:
+
+@code{.sh}
+cc $(pkg-config --cflags glfw3) -o myprog myprog.c $(pkg-config --static --libs glfw3)
+@endcode
+
+If you are using the shared version of the GLFW library, omit the `--static`
+flag.
+
+@code{.sh}
+cc $(pkg-config --cflags glfw3) -o myprog myprog.c $(pkg-config --libs glfw3)
+@endcode
+
+You can also use the `glfw3.pc` file without installing it first, by using the
+`PKG_CONFIG_PATH` environment variable.
+
+@code{.sh}
+env PKG_CONFIG_PATH=path/to/glfw/src cc $(pkg-config --cflags glfw3) -o myprog myprog.c $(pkg-config --libs glfw3)
+@endcode
+
+The dependencies do not include OpenGL, as GLFW loads any OpenGL, OpenGL ES or
+Vulkan libraries it needs at runtime.  If your application calls OpenGL
+directly, instead of using a modern
+[extension loader library](@ref context_glext_auto), you should add the `gl`
+pkg-config package.
+
+@code{.sh}
+cc $(pkg-config --cflags glfw3 gl) -o myprog myprog.c $(pkg-config --libs glfw3 gl)
+@endcode
+
+
+@subsection build_link_xcode With Xcode on macOS
+
+If you are using the dynamic library version of GLFW, add it to the project
+dependencies.
+
+If you are using the static library version of GLFW, add it and the Cocoa,
+OpenGL and IOKit frameworks to the project as dependencies.  They can all be
+found in `/System/Library/Frameworks`.
+
+
+@subsection build_link_osx With command-line on macOS
+
+It is recommended that you use [pkg-config](@ref build_link_pkgconfig) when
+building from the command line on macOS.  That way you will get any new
+dependencies added automatically.  If you still wish to build manually, you need
+to add the required frameworks and libraries to your command-line yourself using
+the `-l` and `-framework` switches.
+
+If you are using the dynamic GLFW library, which is named `libglfw.3.dylib`, do:
+
+@code{.sh}
+cc -o myprog myprog.c -lglfw -framework Cocoa -framework OpenGL -framework IOKit
+@endcode
+
+If you are using the static library, named `libglfw3.a`, substitute `-lglfw3`
+for `-lglfw`.
+
+Note that you do not add the `.framework` extension to a framework when linking
+against it from the command-line.
+
+@note Your machine may have `libGL.*.dylib` style OpenGL library, but that is
+for the X Window System and will not work with the macOS native version of GLFW.

+
+@page compat_guide Standards conformance
+
+@tableofcontents
+
+This guide describes the various API extensions used by this version of GLFW.
+It lists what are essentially implementation details, but which are nonetheless
+vital knowledge for developers intending to deploy their applications on a wide
+range of machines.
+
+The information in this guide is not a part of GLFW API, but merely
+preconditions for some parts of the library to function on a given machine.  Any
+part of this information may change in future versions of GLFW and that will not
+be considered a breaking API change.
+
+
+@section compat_x11 X11 extensions, protocols and IPC standards
+
+As GLFW uses Xlib directly, without any intervening toolkit
+library, it has sole responsibility for interacting well with the many and
+varied window managers in use on Unix-like systems.  In order for applications
+and window managers to work well together, a number of standards and
+conventions have been developed that regulate behavior outside the scope of the
+X11 API; most importantly the
+[Inter-Client Communication Conventions Manual](https://www.tronche.com/gui/x/icccm/)
+(ICCCM) and
+[Extended Window Manager Hints](https://standards.freedesktop.org/wm-spec/wm-spec-latest.html)
+(EWMH) standards.
+
+GLFW uses the `_MOTIF_WM_HINTS` window property to support borderless windows.
+If the running window manager does not support this property, the
+`GLFW_DECORATED` hint will have no effect.
+
+GLFW uses the ICCCM `WM_DELETE_WINDOW` protocol to intercept the user
+attempting to close the GLFW window.  If the running window manager does not
+support this protocol, the close callback will never be called.
+
+GLFW uses the EWMH `_NET_WM_PING` protocol, allowing the window manager notify
+the user when the application has stopped responding, i.e. when it has ceased to
+process events.  If the running window manager does not support this protocol,
+the user will not be notified if the application locks up.
+
+GLFW uses the EWMH `_NET_WM_STATE_FULLSCREEN` window state to tell the window
+manager to make the GLFW window full screen.  If the running window manager does
+not support this state, full screen windows may not work properly.  GLFW has
+a fallback code path in case this state is unavailable, but every window manager
+behaves slightly differently in this regard.
+
+GLFW uses the EWMH `_NET_WM_BYPASS_COMPOSITOR` window property to tell a
+compositing window manager to un-redirect full screen GLFW windows.  If the
+running window manager uses compositing but does not support this property then
+additional copying may be performed for each buffer swap of full screen windows.
+
+GLFW uses the
+[clipboard manager protocol](https://www.freedesktop.org/wiki/ClipboardManager/)
+to push a clipboard string (i.e. selection) owned by a GLFW window about to be
+destroyed to the clipboard manager.  If there is no running clipboard manager,
+the clipboard string will be unavailable once the window has been destroyed.
+
+GLFW uses the
+[X drag-and-drop protocol](https://www.freedesktop.org/wiki/Specifications/XDND/)
+to provide file drop events.  If the application originating the drag does not
+support this protocol, drag and drop will not work.
+
+GLFW uses the XRandR 1.3 extension to provide multi-monitor support.  If the
+running X server does not support this version of this extension, multi-monitor
+support will not function and only a single, desktop-spanning monitor will be
+reported.
+
+GLFW uses the XRandR 1.3 and Xf86vidmode extensions to provide gamma ramp
+support.  If the running X server does not support either or both of these
+extensions, gamma ramp support will not function.
+
+GLFW uses the Xkb extension and detectable auto-repeat to provide keyboard
+input.  If the running X server does not support this extension, a non-Xkb
+fallback path is used.
+
+GLFW uses the XInput2 extension to provide raw, non-accelerated mouse motion
+when the cursor is disabled.  If the running X server does not support this
+extension, regular accelerated mouse motion will be used.
+
+GLFW uses both the XRender extension and the compositing manager to support
+transparent window framebuffers.  If the running X server does not support this
+extension or there is no running compositing manager, the
+`GLFW_TRANSPARENT_FRAMEBUFFER` framebuffer hint will have no effect.
+
+
+@section compat_wayland Wayland protocols and IPC standards
+
+As GLFW uses libwayland directly, without any intervening toolkit library, it
+has sole responsibility for interacting well with every compositor in use on
+Unix-like systems.  Most of the features are provided by the core protocol,
+while cursor support is provided by the libwayland-cursor helper library, EGL
+integration by libwayland-egl, and keyboard handling by
+[libxkbcommon](https://xkbcommon.org/).  In addition, GLFW uses some protocols
+from wayland-protocols to provide additional features if the compositor
+supports them.
+
+GLFW uses xkbcommon 0.5.0 to provide compose key support.  When it has been
+built against an older xkbcommon, the compose key will be disabled even if it
+has been configured in the compositor.
+
+GLFW uses the [xdg-shell
+protocol](https://cgit.freedesktop.org/wayland/wayland-protocols/tree/stable/xdg-shell/xdg-shell.xml)
+to provide better window management.  This protocol is part of
+wayland-protocols 1.12, and mandatory at build time.  If the running compositor
+does not support this protocol, the older [wl_shell
+interface](https://cgit.freedesktop.org/wayland/wayland/tree/protocol/wayland.xml#n972)
+will be used instead.  This will result in a worse integration with the
+desktop, especially on tiling compositors.
+
+GLFW uses the [relative pointer
+protocol](https://cgit.freedesktop.org/wayland/wayland-protocols/tree/unstable/relative-pointer/relative-pointer-unstable-v1.xml)
+alongside the [pointer constraints
+protocol](https://cgit.freedesktop.org/wayland/wayland-protocols/tree/unstable/pointer-constraints/pointer-constraints-unstable-v1.xml)
+to implement disabled cursor.  These two protocols are part of
+wayland-protocols 1.1, and mandatory at build time.  If the running compositor
+does not support both of these protocols, disabling the cursor will have no
+effect.
+
+GLFW uses the [idle inhibit
+protocol](https://cgit.freedesktop.org/wayland/wayland-protocols/tree/unstable/idle-inhibit/idle-inhibit-unstable-v1.xml)
+to prohibit the screensaver from starting.  This protocol is part of
+wayland-protocols 1.6, and mandatory at build time.  If the running compositor
+does not support this protocol, the screensaver may start even for full screen
+windows.
+
+GLFW uses the [xdg-decoration
+protocol](https://cgit.freedesktop.org/wayland/wayland-protocols/tree/unstable/xdg-decoration/xdg-decoration-unstable-v1.xml)
+to request decorations to be drawn around its windows.  This protocol is part
+of wayland-protocols 1.15, and mandatory at build time.  If the running
+compositor does not support this protocol, a very simple frame will be drawn by
+GLFW itself, using the [viewporter
+protocol](https://cgit.freedesktop.org/wayland/wayland-protocols/tree/stable/viewporter/viewporter.xml)
+alongside
+[subsurfaces](https://cgit.freedesktop.org/wayland/wayland/tree/protocol/wayland.xml#n2598).
+This protocol is part of wayland-protocols 1.4, and mandatory at build time.
+If the running compositor does not support this protocol either, no decorations
+will be drawn around windows.
+
+
+@section compat_glx GLX extensions
+
+The GLX API is the default API used to create OpenGL contexts on Unix-like
+systems using the X Window System.
+
+GLFW uses the GLX 1.3 `GLXFBConfig` functions to enumerate and select framebuffer pixel
+formats.  If GLX 1.3 is not supported, @ref glfwInit will fail.
+
+GLFW uses the `GLX_MESA_swap_control,` `GLX_EXT_swap_control` and
+`GLX_SGI_swap_control` extensions to provide vertical retrace synchronization
+(or _vsync_), in that order of preference.  Where none of these extension are
+available, calling @ref glfwSwapInterval will have no effect.
+
+GLFW uses the `GLX_ARB_multisample` extension to create contexts with
+multisampling anti-aliasing.  Where this extension is unavailable, the
+`GLFW_SAMPLES` hint will have no effect.
+
+GLFW uses the `GLX_ARB_create_context` extension when available, even when
+creating OpenGL contexts of version 2.1 and below.  Where this extension is
+unavailable, the `GLFW_CONTEXT_VERSION_MAJOR` and `GLFW_CONTEXT_VERSION_MINOR`
+hints will only be partially supported, the `GLFW_OPENGL_DEBUG_CONTEXT` hint
+will have no effect, and setting the `GLFW_OPENGL_PROFILE` or
+`GLFW_OPENGL_FORWARD_COMPAT` hints to `GLFW_TRUE` will cause @ref
+glfwCreateWindow to fail.
+
+GLFW uses the `GLX_ARB_create_context_profile` extension to provide support for
+context profiles.  Where this extension is unavailable, setting the
+`GLFW_OPENGL_PROFILE` hint to anything but `GLFW_OPENGL_ANY_PROFILE`, or setting
+`GLFW_CLIENT_API` to anything but `GLFW_OPENGL_API` or `GLFW_NO_API` will cause
+@ref glfwCreateWindow to fail.
+
+GLFW uses the `GLX_ARB_context_flush_control` extension to provide control over
+whether a context is flushed when it is released (made non-current).  Where this
+extension is unavailable, the `GLFW_CONTEXT_RELEASE_BEHAVIOR` hint will have no
+effect and the context will always be flushed when released.
+
+GLFW uses the `GLX_ARB_framebuffer_sRGB` and `GLX_EXT_framebuffer_sRGB`
+extensions to provide support for sRGB framebuffers.  Where both of these
+extensions are unavailable, the `GLFW_SRGB_CAPABLE` hint will have no effect.
+
+
+@section compat_wgl WGL extensions
+
+The WGL API is used to create OpenGL contexts on Microsoft Windows and other
+implementations of the Win32 API, such as Wine.
+
+GLFW uses either the `WGL_EXT_extension_string` or the
+`WGL_ARB_extension_string` extension to check for the presence of all other WGL
+extensions listed below.  If both are available, the EXT one is preferred.  If
+neither is available, no other extensions are used and many GLFW features
+related to context creation will have no effect or cause errors when used.
+
+GLFW uses the `WGL_EXT_swap_control` extension to provide vertical retrace
+synchronization (or _vsync_).  Where this extension is unavailable, calling @ref
+glfwSwapInterval will have no effect.
+
+GLFW uses the `WGL_ARB_pixel_format` and `WGL_ARB_multisample` extensions to
+create contexts with multisampling anti-aliasing.  Where these extensions are
+unavailable, the `GLFW_SAMPLES` hint will have no effect.
+
+GLFW uses the `WGL_ARB_create_context` extension when available, even when
+creating OpenGL contexts of version 2.1 and below.  Where this extension is
+unavailable, the `GLFW_CONTEXT_VERSION_MAJOR` and `GLFW_CONTEXT_VERSION_MINOR`
+hints will only be partially supported, the `GLFW_OPENGL_DEBUG_CONTEXT` hint
+will have no effect, and setting the `GLFW_OPENGL_PROFILE` or
+`GLFW_OPENGL_FORWARD_COMPAT` hints to `GLFW_TRUE` will cause @ref
+glfwCreateWindow to fail.
+
+GLFW uses the `WGL_ARB_create_context_profile` extension to provide support for
+context profiles.  Where this extension is unavailable, setting the
+`GLFW_OPENGL_PROFILE` hint to anything but `GLFW_OPENGL_ANY_PROFILE` will cause
+@ref glfwCreateWindow to fail.
+
+GLFW uses the `WGL_ARB_context_flush_control` extension to provide control over
+whether a context is flushed when it is released (made non-current).  Where this
+extension is unavailable, the `GLFW_CONTEXT_RELEASE_BEHAVIOR` hint will have no
+effect and the context will always be flushed when released.
+
+GLFW uses the `WGL_ARB_framebuffer_sRGB` and `WGL_EXT_framebuffer_sRGB`
+extensions to provide support for sRGB framebuffers.  Where both of these
+extension are unavailable, the `GLFW_SRGB_CAPABLE` hint will have no effect.
+
+
+@section compat_osx OpenGL on macOS
+
+Support for OpenGL 3.2 and above was introduced with OS X 10.7 and even then
+only forward-compatible, core profile contexts are supported.  Support for
+OpenGL 4.1 was introduced with OS X 10.9, also limited to forward-compatible,
+core profile contexts.  There is also still no mechanism for requesting debug
+contexts or no-error contexts.  Versions of Mac OS X earlier than 10.7 support
+at most OpenGL version 2.1.
+
+Because of this, on OS X 10.7 and later, the `GLFW_CONTEXT_VERSION_MAJOR` and
+`GLFW_CONTEXT_VERSION_MINOR` hints will cause @ref glfwCreateWindow to fail if
+given version 3.0 or 3.1.  The `GLFW_OPENGL_FORWARD_COMPAT` hint must be set to
+`GLFW_TRUE` and the `GLFW_OPENGL_PROFILE` hint must be set to
+`GLFW_OPENGL_CORE_PROFILE` when creating OpenGL 3.2 and later contexts.  The
+`GLFW_OPENGL_DEBUG_CONTEXT` and `GLFW_CONTEXT_NO_ERROR` hints are ignored.
+
+Also, on Mac OS X 10.6 and below, the `GLFW_CONTEXT_VERSION_MAJOR` and
+`GLFW_CONTEXT_VERSION_MINOR` hints will fail if given a version above 2.1,
+setting the `GLFW_OPENGL_PROFILE` or `GLFW_OPENGL_FORWARD_COMPAT` hints to
+a non-default value will cause @ref glfwCreateWindow to fail and the
+`GLFW_OPENGL_DEBUG_CONTEXT` hint is ignored.
+
+
+@section compat_vulkan Vulkan loader and API
+
+By default, GLFW uses the standard system-wide Vulkan loader to access the
+Vulkan API on all platforms except macOS.  This is installed by both graphics
+drivers and Vulkan SDKs.  If either the loader or at least one minimally
+functional ICD is missing, @ref glfwVulkanSupported will return `GLFW_FALSE` and
+all other Vulkan-related functions will fail with an @ref GLFW_API_UNAVAILABLE
+error.
+
+
+@section compat_wsi Vulkan WSI extensions
+
+The Vulkan WSI extensions are used to create Vulkan surfaces for GLFW windows on
+all supported platforms.
+
+GLFW uses the `VK_KHR_surface` and `VK_KHR_win32_surface` extensions to create
+surfaces on Microsoft Windows.  If any of these extensions are not available,
+@ref glfwGetRequiredInstanceExtensions will return an empty list and window
+surface creation will fail.
+
+GLFW uses the `VK_KHR_surface` and either the `VK_MVK_macos_surface` or
+`VK_EXT_metal_surface` extensions to create surfaces on macOS.  If any of these
+extensions are not available, @ref glfwGetRequiredInstanceExtensions will
+return an empty list and window surface creation will fail.
+
+GLFW uses the `VK_KHR_surface` and either the `VK_KHR_xlib_surface` or
+`VK_KHR_xcb_surface` extensions to create surfaces on X11.  If `VK_KHR_surface`
+or both `VK_KHR_xlib_surface` and `VK_KHR_xcb_surface` are not available, @ref
+glfwGetRequiredInstanceExtensions will return an empty list and window surface
+creation will fail.
+
+GLFW uses the `VK_KHR_surface` and `VK_KHR_wayland_surface` extensions to create
+surfaces on Wayland.  If any of these extensions are not available, @ref
+glfwGetRequiredInstanceExtensions will return an empty list and window surface
+creation will fail.

+
+@page compile_guide Compiling GLFW
+
+@tableofcontents
+
+This is about compiling the GLFW library itself.  For information on how to
+build applications that use GLFW, see @ref build_guide.
+
+
+@section compile_cmake Using CMake
+
+GLFW uses [CMake](https://cmake.org/) to generate project files or makefiles
+for a particular development environment.  If you are on a Unix-like system such
+as Linux or FreeBSD or have a package system like Fink, MacPorts, Cygwin or
+Homebrew, you can install its CMake package.  If not, you can download
+installers for Windows and macOS from the
+[CMake website](https://cmake.org/).
+
+@note CMake only generates project files or makefiles.  It does not compile the
+actual GLFW library.  To compile GLFW, first generate these files for your
+chosen development environment and then use them to compile the actual GLFW
+library.
+
+
+@subsection compile_deps Dependencies
+
+Once you have installed CMake, make sure that all other dependencies are
+available.  On some platforms, GLFW needs a few additional packages to be
+installed.  See the section for your chosen platform and development environment
+below.
+
+
+@subsubsection compile_deps_msvc Dependencies for Visual C++ on Windows
+
+The Windows SDK bundled with Visual C++ already contains all the necessary
+headers, link libraries and tools except for CMake.  Move on to @ref
+compile_generate.
+
+
+@subsubsection compile_deps_mingw Dependencies for MinGW or MinGW-w64 on Windows
+
+Both the MinGW and the MinGW-w64 packages already contain all the necessary
+headers, link libraries and tools except for CMake.  Move on to @ref
+compile_generate.
+
+
+@subsubsection compile_deps_mingw_cross Dependencies for MinGW or MinGW-w64 cross-compilation
+
+Both Cygwin and many Linux distributions have MinGW or MinGW-w64 packages.  For
+example, Cygwin has the `mingw64-i686-gcc` and `mingw64-x86_64-gcc` packages
+for 32- and 64-bit version of MinGW-w64, while Debian GNU/Linux and derivatives
+like Ubuntu have the `mingw-w64` package for both.
+
+GLFW has CMake toolchain files in the `CMake/` directory that set up
+cross-compilation of Windows binaries.  To use these files you add an option
+when running `cmake` to generate the project files or makefiles:
+
+@code{.sh}
+cmake -DCMAKE_TOOLCHAIN_FILE=<toolchain-file> .
+@endcode
+
+The exact toolchain file to use depends on the prefix used by the MinGW or
+MinGW-w64 binaries on your system.  You can usually see this in the /usr
+directory.  For example, both the Debian/Ubuntu and Cygwin MinGW-w64 packages
+have `/usr/x86_64-w64-mingw32` for the 64-bit compilers, so the correct
+invocation would be:
+
+@code{.sh}
+cmake -DCMAKE_TOOLCHAIN_FILE=CMake/x86_64-w64-mingw32.cmake .
+@endcode
+
+For more details see the article
+[CMake Cross Compiling](https://gitlab.kitware.com/cmake/community/wikis/doc/cmake/CrossCompiling) on
+the CMake wiki.
+
+Once you have this set up, move on to @ref compile_generate.
+
+
+@subsubsection compile_deps_xcode Dependencies for Xcode on macOS
+
+Xcode comes with all necessary tools except for CMake.  The required headers
+and libraries are included in the core macOS frameworks.  Xcode can be
+downloaded from the Mac App Store or from the ADC Member Center.
+
+Once you have Xcode installed, move on to @ref compile_generate.
+
+
+@subsubsection compile_deps_x11 Dependencies for Linux and X11
+
+To compile GLFW for X11, you need to have the X11 packages installed, as well as
+the basic development tools like GCC and make.  For example, on Ubuntu and other
+distributions based on Debian GNU/Linux, you need to install the `xorg-dev`
+package, which pulls in all X.org header packages.
+
+Once you have installed the necessary packages, move on to @ref
+compile_generate.
+
+
+@subsubsection compile_deps_wayland Dependencies for Linux and Wayland
+
+To compile GLFW for Wayland, you need to have the Wayland packages installed,
+as well as the basic development tools like GCC and make.  For example, on
+Ubuntu and other distributions based on Debian GNU/Linux, you need to install
+the `libwayland-dev` package, which contains all Wayland headers and pulls in
+wayland-scanner, as well as the `wayland-protocols` and `extra-cmake-modules`
+packages.
+
+Once you have installed the necessary packages, move on to @ref
+compile_generate.
+
+
+@subsection compile_deps_osmesa Dependencies for Linux and OSMesa
+
+To compile GLFW for OSMesa, you need to install the OSMesa library and header
+packages.  For example, on Ubuntu and other distributions based on Debian
+GNU/Linux, you need to install the `libosmesa6-dev` package.  The OSMesa library
+is required at runtime for context creation and is loaded on demand.
+
+Once you have installed the necessary packages, move on to @ref
+compile_generate.
+
+
+@subsection compile_generate Generating build files with CMake
+
+Once you have all necessary dependencies it is time to generate the project
+files or makefiles for your development environment.  CMake needs to know two
+paths for this: the path to the _root_ directory of the GLFW source tree (i.e.
+_not_ the `src` subdirectory) and the target path for the generated files and
+compiled binaries.  If these are the same, it is called an in-tree build,
+otherwise it is called an out-of-tree build.
+
+One of several advantages of out-of-tree builds is that you can generate files
+and compile for different development environments using a single source tree.
+
+@note This section is about generating the project files or makefiles necessary
+to compile the GLFW library, not about compiling the actual library.
+
+
+@subsubsection compile_generate_cli Generating files with the CMake command-line tool
+
+To make an in-tree build, enter the _root_ directory of the GLFW source tree
+(i.e. _not_ the `src` subdirectory) and run CMake.  The current directory is
+used as target path, while the path provided as an argument is used to find the
+source tree.
+
+@code{.sh}
+cd <glfw-root-dir>
+cmake .
+@endcode
+
+To make an out-of-tree build, make a directory outside of the source tree, enter
+it and run CMake with the (relative or absolute) path to the root of the source
+tree as an argument.
+
+@code{.sh}
+mkdir glfw-build
+cd glfw-build
+cmake <glfw-root-dir>
+@endcode
+
+Once you have generated the project files or makefiles for your chosen
+development environment, move on to @ref compile_compile.
+
+
+@subsubsection compile_generate_gui Generating files with the CMake GUI
+
+If you are using the GUI version, choose the root of the GLFW source tree as
+source location and the same directory or another, empty directory as the
+destination for binaries.  Choose _Configure_, change any options you wish to,
+_Configure_ again to let the changes take effect and then _Generate_.
+
+Once you have generated the project files or makefiles for your chosen
+development environment, move on to @ref compile_compile.
+
+
+@subsection compile_compile Compiling the library
+
+You should now have all required dependencies and the project files or makefiles
+necessary to compile GLFW.  Go ahead and compile the actual GLFW library with
+these files, as you would with any other project.
+
+Once the GLFW library is compiled, you are ready to build your applications,
+linking it to the GLFW library.  See @ref build_guide for more information.
+
+
+@subsection compile_options CMake options
+
+The CMake files for GLFW provide a number of options, although not all are
+available on all supported platforms.  Some of these are de facto standards
+among projects using CMake and so have no `GLFW_` prefix.
+
+If you are using the GUI version of CMake, these are listed and can be changed
+from there.  If you are using the command-line version of CMake you can use the
+`ccmake` ncurses GUI to set options.  Some package systems like Ubuntu and other
+distributions based on Debian GNU/Linux have this tool in a separate
+`cmake-curses-gui` package.
+
+Finally, if you don't want to use any GUI, you can set options from the `cmake`
+command-line with the `-D` flag.
+
+@code{.sh}
+cmake -DBUILD_SHARED_LIBS=ON .
+@endcode
+
+
+@subsubsection compile_options_shared Shared CMake options
+
+@anchor BUILD_SHARED_LIBS
+__BUILD_SHARED_LIBS__ determines whether GLFW is built as a static
+library or as a DLL / shared library / dynamic library.
+
+@anchor GLFW_BUILD_EXAMPLES
+__GLFW_BUILD_EXAMPLES__ determines whether the GLFW examples are built
+along with the library.
+
+@anchor GLFW_BUILD_TESTS
+__GLFW_BUILD_TESTS__ determines whether the GLFW test programs are
+built along with the library.
+
+@anchor GLFW_BUILD_DOCS
+__GLFW_BUILD_DOCS__ determines whether the GLFW documentation is built along
+with the library.
+
+@anchor GLFW_VULKAN_STATIC
+__GLFW_VULKAN_STATIC__ determines whether to use the Vulkan loader linked
+directly with the application.
+
+
+@subsubsection compile_options_win32 Windows specific CMake options
+
+@anchor USE_MSVC_RUNTIME_LIBRARY_DLL
+__USE_MSVC_RUNTIME_LIBRARY_DLL__ determines whether to use the DLL version or the
+static library version of the Visual C++ runtime library.  If set to `ON`, the
+DLL version of the Visual C++ library is used.
+
+@anchor GLFW_USE_HYBRID_HPG
+__GLFW_USE_HYBRID_HPG__ determines whether to export the `NvOptimusEnablement` and
+`AmdPowerXpressRequestHighPerformance` symbols, which force the use of the
+high-performance GPU on Nvidia Optimus and AMD PowerXpress systems.  These symbols
+need to be exported by the EXE to be detected by the driver, so the override
+will not work if GLFW is built as a DLL.
+
+
+@section compile_manual Compiling GLFW manually
+
+If you wish to compile GLFW without its CMake build environment then you will
+have to do at least some of the platform detection yourself.  GLFW needs
+a configuration macro to be defined in order to know what window system it's
+being compiled for and also has optional, platform-specific ones for various
+features.
+
+When building with CMake, the `glfw_config.h` configuration header is generated
+based on the current platform and CMake options.  The GLFW CMake environment
+defines @b GLFW_USE_CONFIG_H, which causes this header to be included by
+`internal.h`.  Without this macro, GLFW will expect the necessary configuration
+macros to be defined on the command-line.
+
+The window creation API is used to create windows, handle input, monitors, gamma
+ramps and clipboard.  The options are:
+
+ - @b _GLFW_COCOA to use the Cocoa frameworks
+ - @b _GLFW_WIN32 to use the Win32 API
+ - @b _GLFW_X11 to use the X Window System
+ - @b _GLFW_WAYLAND to use the Wayland API (experimental and incomplete)
+ - @b _GLFW_OSMESA to use the OSMesa API (headless and non-interactive)
+
+If you are building GLFW as a shared library / dynamic library / DLL then you
+must also define @b _GLFW_BUILD_DLL.  Otherwise, you must not define it.
+
+If you are linking the Vulkan loader directly with your application then you
+must also define @b _GLFW_VULKAN_STATIC.  Otherwise, GLFW will attempt to use the
+external version.
+
+If you are using a custom name for the Vulkan, EGL, GLX, OSMesa, OpenGL, GLESv1
+or GLESv2 library, you can override the default names by defining those you need
+of @b _GLFW_VULKAN_LIBRARY, @b _GLFW_EGL_LIBRARY, @b _GLFW_GLX_LIBRARY, @b
+_GLFW_OSMESA_LIBRARY, @b _GLFW_OPENGL_LIBRARY, @b _GLFW_GLESV1_LIBRARY and @b
+_GLFW_GLESV2_LIBRARY.  Otherwise, GLFW will use the built-in default names.
+
+For the EGL context creation API, the following options are available:
+
+ - @b _GLFW_USE_EGLPLATFORM_H to use an existing `EGL/eglplatform.h` header file
+   for native handle types (fallback)
+
+@note None of the @ref build_macros may be defined during the compilation of
+GLFW.  If you define any of these in your build files, make sure they are not
+applied to the GLFW sources.

+@page context_guide Context guide
+
+@tableofcontents
+
+This guide introduces the OpenGL and OpenGL ES context related functions of
+GLFW.  For details on a specific function in this category, see the @ref
+context.  There are also guides for the other areas of the GLFW API.
+
+ - @ref intro_guide
+ - @ref window_guide
+ - @ref vulkan_guide
+ - @ref monitor_guide
+ - @ref input_guide
+
+
+@section context_object Context objects
+
+A window object encapsulates both a top-level window and an OpenGL or OpenGL ES
+context.  It is created with @ref glfwCreateWindow and destroyed with @ref
+glfwDestroyWindow or @ref glfwTerminate.  See @ref window_creation for more
+information.
+
+As the window and context are inseparably linked, the window object also serves
+as the context handle.
+
+To test the creation of various kinds of contexts and see their properties, run
+the `glfwinfo` test program.
+
+@note Vulkan does not have a context and the Vulkan instance is created via the
+Vulkan API itself.  If you will be using Vulkan to render to a window, disable
+context creation by setting the [GLFW_CLIENT_API](@ref GLFW_CLIENT_API_hint)
+hint to `GLFW_NO_API`.  For more information, see the @ref vulkan_guide.
+
+
+@subsection context_hints Context creation hints
+
+There are a number of hints, specified using @ref glfwWindowHint, related to
+what kind of context is created.  See
+[context related hints](@ref window_hints_ctx) in the window guide.
+
+
+@subsection context_sharing Context object sharing
+
+When creating a window and its OpenGL or OpenGL ES context with @ref
+glfwCreateWindow, you can specify another window whose context the new one
+should share its objects (textures, vertex and element buffers, etc.) with.
+
+@code
+GLFWwindow* second_window = glfwCreateWindow(640, 480, "Second Window", NULL, first_window);
+@endcode
+
+Object sharing is implemented by the operating system and graphics driver.  On
+platforms where it is possible to choose which types of objects are shared, GLFW
+requests that all types are shared.
+
+See the relevant chapter of the [OpenGL](https://www.opengl.org/registry/) or
+[OpenGL ES](https://www.khronos.org/opengles/) reference documents for more
+information.  The name and number of this chapter unfortunately varies between
+versions and APIs, but has at times been named _Shared Objects and Multiple
+Contexts_.
+
+GLFW comes with a barebones object sharing example program called `sharing`.
+
+
+@subsection context_offscreen Offscreen contexts
+
+GLFW doesn't support creating contexts without an associated window.  However,
+contexts with hidden windows can be created with the
+[GLFW_VISIBLE](@ref GLFW_VISIBLE_hint) window hint.
+
+@code
+glfwWindowHint(GLFW_VISIBLE, GLFW_FALSE);
+
+GLFWwindow* offscreen_context = glfwCreateWindow(640, 480, "", NULL, NULL);
+@endcode
+
+The window never needs to be shown and its context can be used as a plain
+offscreen context.  Depending on the window manager, the size of a hidden
+window's framebuffer may not be usable or modifiable, so framebuffer
+objects are recommended for rendering with such contexts.
+
+You should still [process events](@ref events) as long as you have at least one
+window, even if none of them are visible.
+
+@macos The first time a window is created the menu bar is created.  This is not
+desirable for example when writing a command-line only application.  Menu bar
+creation can be disabled with the @ref GLFW_COCOA_MENUBAR init hint.
+
+
+@subsection context_less Windows without contexts
+
+You can disable context creation by setting the
+[GLFW_CLIENT_API](@ref GLFW_CLIENT_API_hint) hint to `GLFW_NO_API`.  Windows
+without contexts must not be passed to @ref glfwMakeContextCurrent or @ref
+glfwSwapBuffers.
+
+
+@section context_current Current context
+
+Before you can make OpenGL or OpenGL ES calls, you need to have a current
+context of the correct type.  A context can only be current for a single thread
+at a time, and a thread can only have a single context current at a time.
+
+When moving a context between threads, you must make it non-current on the old
+thread before making it current on the new one.
+
+The context of a window is made current with @ref glfwMakeContextCurrent.
+
+@code
+glfwMakeContextCurrent(window);
+@endcode
+
+The window of the current context is returned by @ref glfwGetCurrentContext.
+
+@code
+GLFWwindow* window = glfwGetCurrentContext();
+@endcode
+
+The following GLFW functions require a context to be current.  Calling any these
+functions without a current context will generate a @ref GLFW_NO_CURRENT_CONTEXT
+error.
+
+ - @ref glfwSwapInterval
+ - @ref glfwExtensionSupported
+ - @ref glfwGetProcAddress
+
+
+@section context_swap Buffer swapping
+
+See @ref buffer_swap in the window guide.
+
+
+@section context_glext OpenGL and OpenGL ES extensions
+
+One of the benefits of OpenGL and OpenGL ES is their extensibility.
+Hardware vendors may include extensions in their implementations that extend the
+API before that functionality is included in a new version of the OpenGL or
+OpenGL ES specification, and some extensions are never included and remain
+as extensions until they become obsolete.
+
+An extension is defined by:
+
+- An extension name (e.g. `GL_ARB_debug_output`)
+- New OpenGL tokens (e.g. `GL_DEBUG_SEVERITY_HIGH_ARB`)
+- New OpenGL functions (e.g. `glGetDebugMessageLogARB`)
+
+Note the `ARB` affix, which stands for Architecture Review Board and is used
+for official extensions.  The extension above was created by the ARB, but there
+are many different affixes, like `NV` for Nvidia and `AMD` for, well, AMD.  Any
+group may also use the generic `EXT` affix.  Lists of extensions, together with
+their specifications, can be found at the
+[OpenGL Registry](https://www.opengl.org/registry/) and
+[OpenGL ES Registry](https://www.khronos.org/registry/gles/).
+
+
+@subsection context_glext_auto Loading extension with a loader library
+
+An extension loader library is the easiest and best way to access both OpenGL and
+OpenGL ES extensions and modern versions of the core OpenGL or OpenGL ES APIs.
+They will take care of all the details of declaring and loading everything you
+need.  One such library is [glad](https://github.com/Dav1dde/glad) and there are
+several others.
+
+The following example will use glad but all extension loader libraries work
+similarly.
+
+First you need to generate the source files using the glad Python script.  This
+example generates a loader for any version of OpenGL, which is the default for
+both GLFW and glad, but loaders for OpenGL ES, as well as loaders for specific
+API versions and extension sets can be generated.  The generated files are
+written to the `output` directory.
+
+@code{.sh}
+python main.py --generator c --no-loader --out-path output
+@endcode
+
+The `--no-loader` option is added because GLFW already provides a function for
+loading OpenGL and OpenGL ES function pointers, one that automatically uses the
+selected context creation API, and glad can call this instead of having to
+implement its own.  There are several other command-line options as well.  See
+the glad documentation for details.
+
+Add the generated `output/src/glad.c`, `output/include/glad/glad.h` and
+`output/include/KHR/khrplatform.h` files to your build.  Then you need to
+include the glad header file, which will replace the OpenGL header of your
+development environment.  By including the glad header before the GLFW header,
+it suppresses the development environment's OpenGL or OpenGL ES header.
+
+@code
+#include <glad/glad.h>
+#include <GLFW/glfw3.h>
+@endcode
+
+Finally you need to initialize glad once you have a suitable current context.
+
+@code
+window = glfwCreateWindow(640, 480, "My Window", NULL, NULL);
+if (!window)
+{
+    ...
+}
+
+glfwMakeContextCurrent(window);
+
+gladLoadGLLoader((GLADloadproc) glfwGetProcAddress);
+@endcode
+
+Once glad has been loaded, you have access to all OpenGL core and extension
+functions supported by both the context you created and the glad loader you
+generated and you are ready to start rendering.
+
+You can specify a minimum required OpenGL or OpenGL ES version with
+[context hints](@ref window_hints_ctx).  If your needs are more complex, you can
+check the actual OpenGL or OpenGL ES version with
+[context attributes](@ref window_attribs_ctx), or you can check whether
+a specific version is supported by the current context with the
+`GLAD_GL_VERSION_x_x` booleans.
+
+@code
+if (GLAD_GL_VERSION_3_2)
+{
+    // Call OpenGL 3.2+ specific code
+}
+@endcode
+
+To check whether a specific extension is supported, use the `GLAD_GL_xxx`
+booleans.
+
+@code
+if (GLAD_GL_ARB_debug_output)
+{
+    // Use GL_ARB_debug_output
+}
+@endcode
+
+
+@subsection context_glext_manual Loading extensions manually
+
+__Do not use this technique__ unless it is absolutely necessary.  An
+[extension loader library](@ref context_glext_auto) will save you a ton of
+tedious, repetitive, error prone work.
+
+To use a certain extension, you must first check whether the context supports
+that extension and then, if it introduces new functions, retrieve the pointers
+to those functions.  GLFW provides @ref glfwExtensionSupported and @ref
+glfwGetProcAddress for manual loading of extensions and new API functions.
+
+This section will demonstrate manual loading of OpenGL extensions.  The loading
+of OpenGL ES extensions is identical except for the name of the extension header.
+
+
+@subsubsection context_glext_header The glext.h header
+
+The `glext.h` extension header is a continually updated file that defines the
+interfaces for all OpenGL extensions.  The latest version of this can always be
+found at the [OpenGL Registry](https://www.opengl.org/registry/).  There are also
+extension headers for the various versions of OpenGL ES at the
+[OpenGL ES Registry](https://www.khronos.org/registry/gles/).  It it strongly
+recommended that you use your own copy of the extension header, as the one
+included in your development environment may be several years out of date and
+may not include the extensions you wish to use.
+
+The header defines function pointer types for all functions of all extensions it
+supports.  These have names like `PFNGLGETDEBUGMESSAGELOGARBPROC` (for
+`glGetDebugMessageLogARB`), i.e. the name is made uppercase and `PFN` (pointer
+to function) and `PROC` (procedure) are added to the ends.
+
+To include the extension header, define @ref GLFW_INCLUDE_GLEXT before including
+the GLFW header.
+
+@code
+#define GLFW_INCLUDE_GLEXT
+#include <GLFW/glfw3.h>
+@endcode
+
+
+@subsubsection context_glext_string Checking for extensions
+
+A given machine may not actually support the extension (it may have older
+drivers or a graphics card that lacks the necessary hardware features), so it
+is necessary to check at run-time whether the context supports the extension.
+This is done with @ref glfwExtensionSupported.
+
+@code
+if (glfwExtensionSupported("GL_ARB_debug_output"))
+{
+    // The extension is supported by the current context
+}
+@endcode
+
+The argument is a null terminated ASCII string with the extension name.  If the
+extension is supported, @ref glfwExtensionSupported returns `GLFW_TRUE`,
+otherwise it returns `GLFW_FALSE`.
+
+
+@subsubsection context_glext_proc Fetching function pointers
+
+Many extensions, though not all, require the use of new OpenGL functions.
+These functions often do not have entry points in the client API libraries of
+your operating system, making it necessary to fetch them at run time.  You can
+retrieve pointers to these functions with @ref glfwGetProcAddress.
+
+@code
+PFNGLGETDEBUGMESSAGELOGARBPROC pfnGetDebugMessageLog = glfwGetProcAddress("glGetDebugMessageLogARB");
+@endcode
+
+In general, you should avoid giving the function pointer variables the (exact)
+same name as the function, as this may confuse your linker.  Instead, you can
+use a different prefix, like above, or some other naming scheme.
+
+Now that all the pieces have been introduced, here is what they might look like
+when used together.
+
+@code
+#define GLFW_INCLUDE_GLEXT
+#include <GLFW/glfw3.h>
+
+#define glGetDebugMessageLogARB pfnGetDebugMessageLog
+PFNGLGETDEBUGMESSAGELOGARBPROC pfnGetDebugMessageLog;
+
+// Flag indicating whether the extension is supported
+int has_ARB_debug_output = 0;
+
+void load_extensions(void)
+{
+    if (glfwExtensionSupported("GL_ARB_debug_output"))
+    {
+        pfnGetDebugMessageLog = (PFNGLGETDEBUGMESSAGELOGARBPROC)
+            glfwGetProcAddress("glGetDebugMessageLogARB");
+        has_ARB_debug_output = 1;
+    }
+}
+
+void some_function(void)
+{
+    if (has_ARB_debug_output)
+    {
+        // Now the extension function can be called as usual
+        glGetDebugMessageLogARB(...);
+    }
+}
+@endcode

For information on how to write such applications, start with the <a class="el" href="quick_guide.html">introductory tutorial</a>. For information on how to compile the GLFW library itself, see <a class="el" href="compile_guide.html">Compiling GLFW</a>.</p>
+<p>This is not a tutorial on compilation or linking. It assumes basic understanding of how to compile and link a C program as well as how to use the specific compiler of your chosen development environment. The compilation and linking process should be explained in your C programming material and in the documentation for your development environment.</p>
+<h1><a class="anchor" id="build_include"></a>
+Including the GLFW header file</h1>
+<p>You should include the GLFW header in the source files where you use OpenGL or GLFW.</p>
+<div class="fragment"><div class="line"><span class="preprocessor">#include &lt;<a class="code" href="glfw3_8h.html">GLFW/glfw3.h</a>&gt;</span></div>
+</div><!-- fragment --><p>This header declares the GLFW API and by default also includes the OpenGL header from your development environment. See below for how to control this.</p>
+<p>The GLFW header also defines any platform-specific macros needed by your OpenGL header, so it can be included without needing any window system headers.</p>
+<p>For example, under Windows you are normally required to include <code>windows.h</code> before the OpenGL header, which would bring in the whole Win32 API. The GLFW header duplicates the small number of macros needed.</p>
+<p>It does this only when needed, so if <code>windows.h</code> <em>is</em> included, the GLFW header does not try to redefine those symbols. The reverse is not true, i.e. <code>windows.h</code> cannot cope if any of its symbols have already been defined.</p>
+<p>In other words:</p>
+<ul>
+<li>Do <em>not</em> include the OpenGL headers yourself, as GLFW does this for you</li>
+<li>Do <em>not</em> include <code>windows.h</code> or other platform-specific headers unless you plan on using those APIs directly</li>
+<li>If you <em>do</em> need to include such headers, do it <em>before</em> including the GLFW header and it will handle this</li>
+</ul>
+<p>If you are using an OpenGL extension loading library such as <a href="https://github.com/Dav1dde/glad">glad</a>, the extension loader header should be included <em>before</em> the GLFW one.</p>
+<div class="fragment"><div class="line"><span class="preprocessor">#include &lt;glad/gl.h&gt;</span></div>
+<div class="line"><span class="preprocessor">#include &lt;<a class="code" href="glfw3_8h.html">GLFW/glfw3.h</a>&gt;</span></div>
+</div><!-- fragment --><p>Alternatively the <a class="el" href="build_guide.html#GLFW_INCLUDE_NONE">GLFW_INCLUDE_NONE</a> macro (described below) can be used to prevent the GLFW header from including the OpenGL header.</p>

+<h1><a class="anchor" id="build_link"></a>
+Link with the right libraries</h1>
+<p>GLFW is essentially a wrapper of various platform-specific APIs and therefore needs to link against many different system libraries. If you are using GLFW as a shared library / dynamic library / DLL then it takes care of these links. However, if you are using GLFW as a static library then your executable will need to link against these libraries.</p>
+<p>On Windows and macOS, the list of system libraries is static and can be hard-coded into your build environment. See the section for your development environment below. On Linux and other Unix-like operating systems, the list varies but can be retrieved in various ways as described below.</p>
+<p>A good general introduction to linking is <a href="https://www.lurklurk.org/linkers/linkers.html">Beginner's Guide to Linkers</a> by David Drysdale.</p>
+<h2><a class="anchor" id="build_link_win32"></a>
+With MinGW or Visual C++ on Windows</h2>
+<p>The static version of the GLFW library is named <code>glfw3</code>. When using this version, it is also necessary to link with some libraries that GLFW uses.</p>
+<p>When using MinGW to link an application with the static version of GLFW, you must also explicitly link with <code>gdi32</code>. Other toolchains including MinGW-w64 include it in the set of default libraries along with other dependencies like <code>user32</code> and <code>kernel32</code>.</p>
+<p>The link library for the GLFW DLL is named <code>glfw3dll</code>. When compiling an application that uses the DLL version of GLFW, you need to define the <a class="el" href="build_guide.html#GLFW_DLL">GLFW_DLL</a> macro <em>before</em> any inclusion of the GLFW header. This can be done either with a compiler switch or by defining it in your source code.</p>
+<h2><a class="anchor" id="build_link_cmake_source"></a>
+With CMake and GLFW source</h2>
+<p>This section is about using CMake to compile and link GLFW along with your application. If you want to use an installed binary instead, see <a class="el" href="build_guide.html#build_link_cmake_package">With CMake and installed GLFW binaries</a>.</p>
+<p>With a few changes to your <code>CMakeLists.txt</code> you can have the GLFW source tree built along with your application.</p>
+<p>When including GLFW as part of your build, you probably don't want to build the GLFW tests, examples and documentation. To disable these, set the corresponding cache variables before adding the GLFW source tree.</p>
+<div class="fragment"><div class="line">set(GLFW_BUILD_DOCS OFF CACHE BOOL <span class="stringliteral">&quot;&quot;</span> FORCE)</div>
+<div class="line">set(GLFW_BUILD_TESTS OFF CACHE BOOL <span class="stringliteral">&quot;&quot;</span> FORCE)</div>
+<div class="line">set(GLFW_BUILD_EXAMPLES OFF CACHE BOOL <span class="stringliteral">&quot;&quot;</span> FORCE)</div>
+</div><!-- fragment --><p>Add the root directory of the GLFW source tree to your project. This will add the <code>glfw</code> target to your project.</p>
+<div class="fragment"><div class="line">add_subdirectory(path/to/glfw)</div>
+</div><!-- fragment --><p>Once GLFW has been added, link your application against the <code>glfw</code> target. This adds the GLFW library and its link-time dependencies as it is currently configured, the include directory for the GLFW header and, when applicable, the <a class="el" href="build_guide.html#GLFW_DLL">GLFW_DLL</a> macro.</p>
+<div class="fragment"><div class="line">target_link_libraries(myapp glfw)</div>
+</div><!-- fragment --><p>Note that the <code>glfw</code> target does not depend on OpenGL, as GLFW loads any OpenGL, OpenGL ES or Vulkan libraries it needs at runtime. If your application calls OpenGL directly, instead of using a modern <a class="el" href="context_guide.html#context_glext_auto">extension loader library</a>, use the OpenGL CMake package.</p>
+<div class="fragment"><div class="line">find_package(OpenGL REQUIRED)</div>
+</div><!-- fragment --><p>If OpenGL is found, the <code>OpenGL::GL</code> target is added to your project, containing library and include directory paths. Link against this like above.</p>
+<div class="fragment"><div class="line">target_link_libraries(myapp OpenGL::GL)</div>
+</div><!-- fragment --><h2><a class="anchor" id="build_link_cmake_package"></a>
+With CMake and installed GLFW binaries</h2>
+<p>This section is about using CMake to link GLFW after it has been built and installed. If you want to build it along with your application instead, see <a class="el" href="build_guide.html#build_link_cmake_source">With CMake and GLFW source</a>.</p>
+<p>With a few changes to your <code>CMakeLists.txt</code> you can locate the package and target files generated when GLFW is installed.</p>
+<div class="fragment"><div class="line">find_package(glfw3 3.3 REQUIRED)</div>
+</div><!-- fragment --><p>Once GLFW has been added to the project, link against it with the <code>glfw</code> target. This adds the GLFW library and its link-time dependencies, the include directory for the GLFW header and, when applicable, the <a class="el" href="build_guide.html#GLFW_DLL">GLFW_DLL</a> macro.</p>
+<div class="fragment"><div class="line">target_link_libraries(myapp glfw)</div>
+</div><!-- fragment --><p>Note that the <code>glfw</code> target does not depend on OpenGL, as GLFW loads any OpenGL, OpenGL ES or Vulkan libraries it needs at runtime. If your application calls OpenGL directly, instead of using a modern <a class="el" href="context_guide.html#context_glext_auto">extension loader library</a>, use the OpenGL CMake package.</p>
+<div class="fragment"><div class="line">find_package(OpenGL REQUIRED)</div>
+</div><!-- fragment --><p>If OpenGL is found, the <code>OpenGL::GL</code> target is added to your project, containing library and include directory paths. Link against this like above.</p>
+<div class="fragment"><div class="line">target_link_libraries(myapp OpenGL::GL)</div>
+</div><!-- fragment --><h2><a class="anchor" id="build_link_pkgconfig"></a>
+With makefiles and pkg-config on Unix</h2>
+<p>GLFW supports <a href="https://www.freedesktop.org/wiki/Software/pkg-config/">pkg-config</a>, and the <code>glfw3.pc</code> pkg-config file is generated when the GLFW library is built and is installed along with it. A pkg-config file describes all necessary compile-time and link-time flags and dependencies needed to use a library. When they are updated or if they differ between systems, you will get the correct ones automatically.</p>
+<p>A typical compile and link command-line when using the static version of the GLFW library may look like this:</p>
+<div class="fragment"><div class="line">cc $(pkg-config --cflags glfw3) -o myprog myprog.c $(pkg-config --static --libs glfw3)</div>
+</div><!-- fragment --><p>If you are using the shared version of the GLFW library, omit the <code>--static</code> flag.</p>
+<div class="fragment"><div class="line">cc $(pkg-config --cflags glfw3) -o myprog myprog.c $(pkg-config --libs glfw3)</div>
+</div><!-- fragment --><p>You can also use the <code>glfw3.pc</code> file without installing it first, by using the <code>PKG_CONFIG_PATH</code> environment variable.</p>
+<div class="fragment"><div class="line">env PKG_CONFIG_PATH=path/to/glfw/src cc $(pkg-config --cflags glfw3) -o myprog myprog.c $(pkg-config --libs glfw3)</div>
+</div><!-- fragment --><p>The dependencies do not include OpenGL, as GLFW loads any OpenGL, OpenGL ES or Vulkan libraries it needs at runtime. If your application calls OpenGL directly, instead of using a modern <a class="el" href="context_guide.html#context_glext_auto">extension loader library</a>, you should add the <code>gl</code> pkg-config package.</p>
+<div class="fragment"><div class="line">cc $(pkg-config --cflags glfw3 gl) -o myprog myprog.c $(pkg-config --libs glfw3 gl)</div>
+</div><!-- fragment --><h2><a class="anchor" id="build_link_xcode"></a>
+With Xcode on macOS</h2>
+<p>If you are using the dynamic library version of GLFW, add it to the project dependencies.</p>
+<p>If you are using the static library version of GLFW, add it and the Cocoa, OpenGL and IOKit frameworks to the project as dependencies. They can all be found in <code>/System/Library/Frameworks</code>.</p>
+<h2><a class="anchor" id="build_link_osx"></a>
+With command-line on macOS</h2>
+<p>It is recommended that you use <a class="el" href="build_guide.html#build_link_pkgconfig">pkg-config</a> when building from the command line on macOS. That way you will get any new dependencies added automatically. If you still wish to build manually, you need to add the required frameworks and libraries to your command-line yourself using the <code>-l</code> and <code>-framework</code> switches.</p>
+<p>If you are using the dynamic GLFW library, which is named <code>libglfw.3.dylib</code>, do:</p>
+<div class="fragment"><div class="line">cc -o myprog myprog.c -lglfw -framework Cocoa -framework OpenGL -framework IOKit</div>
+</div><!-- fragment --><p>If you are using the static library, named <code>libglfw3.a</code>, substitute <code>-lglfw3</code> for <code>-lglfw</code>.</p>
+<p>Note that you do not add the <code>.framework</code> extension to a framework when linking against it from the command-line.</p>
+<dl class="section note"><dt>Note</dt><dd>Your machine may have <code>libGL.*.dylib</code> style OpenGL library, but that is for the X Window System and will not work with the macOS native version of GLFW. </dd></dl>

+<div class="textblock"><p>This guide describes the various API extensions used by this version of GLFW. It lists what are essentially implementation details, but which are nonetheless vital knowledge for developers intending to deploy their applications on a wide range of machines.</p>
+<p>The information in this guide is not a part of GLFW API, but merely preconditions for some parts of the library to function on a given machine. Any part of this information may change in future versions of GLFW and that will not be considered a breaking API change.</p>
+<h1><a class="anchor" id="compat_x11"></a>
+X11 extensions, protocols and IPC standards</h1>
+<p>As GLFW uses Xlib directly, without any intervening toolkit library, it has sole responsibility for interacting well with the many and varied window managers in use on Unix-like systems. In order for applications and window managers to work well together, a number of standards and conventions have been developed that regulate behavior outside the scope of the X11 API; most importantly the <a href="https://www.tronche.com/gui/x/icccm/">Inter-Client Communication Conventions Manual</a> (ICCCM) and <a href="https://standards.freedesktop.org/wm-spec/wm-spec-latest.html">Extended Window Manager Hints</a> (EWMH) standards.</p>
+<p>GLFW uses the <code>_MOTIF_WM_HINTS</code> window property to support borderless windows. If the running window manager does not support this property, the <code>GLFW_DECORATED</code> hint will have no effect.</p>
+<p>GLFW uses the ICCCM <code>WM_DELETE_WINDOW</code> protocol to intercept the user attempting to close the GLFW window. If the running window manager does not support this protocol, the close callback will never be called.</p>
+<p>GLFW uses the EWMH <code>_NET_WM_PING</code> protocol, allowing the window manager notify the user when the application has stopped responding, i.e. when it has ceased to process events. If the running window manager does not support this protocol, the user will not be notified if the application locks up.</p>
+<p>GLFW uses the EWMH <code>_NET_WM_STATE_FULLSCREEN</code> window state to tell the window manager to make the GLFW window full screen. If the running window manager does not support this state, full screen windows may not work properly. GLFW has a fallback code path in case this state is unavailable, but every window manager behaves slightly differently in this regard.</p>
+<p>GLFW uses the EWMH <code>_NET_WM_BYPASS_COMPOSITOR</code> window property to tell a compositing window manager to un-redirect full screen GLFW windows. If the running window manager uses compositing but does not support this property then additional copying may be performed for each buffer swap of full screen windows.</p>
+<p>GLFW uses the <a href="https://www.freedesktop.org/wiki/ClipboardManager/">clipboard manager protocol</a> to push a clipboard string (i.e. selection) owned by a GLFW window about to be destroyed to the clipboard manager. If there is no running clipboard manager, the clipboard string will be unavailable once the window has been destroyed.</p>
+<p>GLFW uses the <a href="https://www.freedesktop.org/wiki/Specifications/XDND/">X drag-and-drop protocol</a> to provide file drop events. If the application originating the drag does not support this protocol, drag and drop will not work.</p>
+<p>GLFW uses the XRandR 1.3 extension to provide multi-monitor support. If the running X server does not support this version of this extension, multi-monitor support will not function and only a single, desktop-spanning monitor will be reported.</p>
+<p>GLFW uses the XRandR 1.3 and Xf86vidmode extensions to provide gamma ramp support. If the running X server does not support either or both of these extensions, gamma ramp support will not function.</p>
+<p>GLFW uses the Xkb extension and detectable auto-repeat to provide keyboard input. If the running X server does not support this extension, a non-Xkb fallback path is used.</p>
+<p>GLFW uses the XInput2 extension to provide raw, non-accelerated mouse motion when the cursor is disabled. If the running X server does not support this extension, regular accelerated mouse motion will be used.</p>
+<p>GLFW uses both the XRender extension and the compositing manager to support transparent window framebuffers. If the running X server does not support this extension or there is no running compositing manager, the <code>GLFW_TRANSPARENT_FRAMEBUFFER</code> framebuffer hint will have no effect.</p>
+<h1><a class="anchor" id="compat_wayland"></a>
+Wayland protocols and IPC standards</h1>
+<p>As GLFW uses libwayland directly, without any intervening toolkit library, it has sole responsibility for interacting well with every compositor in use on Unix-like systems. Most of the features are provided by the core protocol, while cursor support is provided by the libwayland-cursor helper library, EGL integration by libwayland-egl, and keyboard handling by <a href="https://xkbcommon.org/">libxkbcommon</a>. In addition, GLFW uses some protocols from wayland-protocols to provide additional features if the compositor supports them.</p>
+<p>GLFW uses xkbcommon 0.5.0 to provide compose key support. When it has been built against an older xkbcommon, the compose key will be disabled even if it has been configured in the compositor.</p>
+<p>GLFW uses the <a href="https://cgit.freedesktop.org/wayland/wayland-protocols/tree/stable/xdg-shell/xdg-shell.xml">xdg-shell protocol</a> to provide better window management. This protocol is part of wayland-protocols 1.12, and mandatory at build time. If the running compositor does not support this protocol, the older <a href="https://cgit.freedesktop.org/wayland/wayland/tree/protocol/wayland.xml#n972">wl_shell interface</a> will be used instead. This will result in a worse integration with the desktop, especially on tiling compositors.</p>
+<p>GLFW uses the <a href="https://cgit.freedesktop.org/wayland/wayland-protocols/tree/unstable/relative-pointer/relative-pointer-unstable-v1.xml">relative pointer protocol</a> alongside the <a href="https://cgit.freedesktop.org/wayland/wayland-protocols/tree/unstable/pointer-constraints/pointer-constraints-unstable-v1.xml">pointer constraints protocol</a> to implement disabled cursor. These two protocols are part of wayland-protocols 1.1, and mandatory at build time. If the running compositor does not support both of these protocols, disabling the cursor will have no effect.</p>
+<p>GLFW uses the <a href="https://cgit.freedesktop.org/wayland/wayland-protocols/tree/unstable/idle-inhibit/idle-inhibit-unstable-v1.xml">idle inhibit protocol</a> to prohibit the screensaver from starting. This protocol is part of wayland-protocols 1.6, and mandatory at build time. If the running compositor does not support this protocol, the screensaver may start even for full screen windows.</p>
+<p>GLFW uses the <a href="https://cgit.freedesktop.org/wayland/wayland-protocols/tree/unstable/xdg-decoration/xdg-decoration-unstable-v1.xml">xdg-decoration protocol</a> to request decorations to be drawn around its windows. This protocol is part of wayland-protocols 1.15, and mandatory at build time. If the running compositor does not support this protocol, a very simple frame will be drawn by GLFW itself, using the <a href="https://cgit.freedesktop.org/wayland/wayland-protocols/tree/stable/viewporter/viewporter.xml">viewporter protocol</a> alongside <a href="https://cgit.freedesktop.org/wayland/wayland/tree/protocol/wayland.xml#n2598">subsurfaces</a>. This protocol is part of wayland-protocols 1.4, and mandatory at build time. If the running compositor does not support this protocol either, no decorations will be drawn around windows.</p>
+<h1><a class="anchor" id="compat_glx"></a>
+GLX extensions</h1>
+<p>The GLX API is the default API used to create OpenGL contexts on Unix-like systems using the X Window System.</p>
+<p>GLFW uses the GLX 1.3 <code>GLXFBConfig</code> functions to enumerate and select framebuffer pixel formats. If GLX 1.3 is not supported, <a class="el" href="group__init.html#ga317aac130a235ab08c6db0834907d85e">glfwInit</a> will fail.</p>
+<p>GLFW uses the <code>GLX_MESA_swap_control,</code> <code>GLX_EXT_swap_control</code> and <code>GLX_SGI_swap_control</code> extensions to provide vertical retrace synchronization (or <em>vsync</em>), in that order of preference. Where none of these extension are available, calling <a class="el" href="group__context.html#ga6d4e0cdf151b5e579bd67f13202994ed">glfwSwapInterval</a> will have no effect.</p>
+<p>GLFW uses the <code>GLX_ARB_multisample</code> extension to create contexts with multisampling anti-aliasing. Where this extension is unavailable, the <code>GLFW_SAMPLES</code> hint will have no effect.</p>
+<p>GLFW uses the <code>GLX_ARB_create_context</code> extension when available, even when creating OpenGL contexts of version 2.1 and below. Where this extension is unavailable, the <code>GLFW_CONTEXT_VERSION_MAJOR</code> and <code>GLFW_CONTEXT_VERSION_MINOR</code> hints will only be partially supported, the <code>GLFW_OPENGL_DEBUG_CONTEXT</code> hint will have no effect, and setting the <code>GLFW_OPENGL_PROFILE</code> or <code>GLFW_OPENGL_FORWARD_COMPAT</code> hints to <code>GLFW_TRUE</code> will cause <a class="el" href="group__window.html#ga5c336fddf2cbb5b92f65f10fb6043344">glfwCreateWindow</a> to fail.</p>
+<p>GLFW uses the <code>GLX_ARB_create_context_profile</code> extension to provide support for context profiles. Where this extension is unavailable, setting the <code>GLFW_OPENGL_PROFILE</code> hint to anything but <code>GLFW_OPENGL_ANY_PROFILE</code>, or setting <code>GLFW_CLIENT_API</code> to anything but <code>GLFW_OPENGL_API</code> or <code>GLFW_NO_API</code> will cause <a class="el" href="group__window.html#ga5c336fddf2cbb5b92f65f10fb6043344">glfwCreateWindow</a> to fail.</p>
+<p>GLFW uses the <code>GLX_ARB_context_flush_control</code> extension to provide control over whether a context is flushed when it is released (made non-current). Where this extension is unavailable, the <code>GLFW_CONTEXT_RELEASE_BEHAVIOR</code> hint will have no effect and the context will always be flushed when released.</p>
+<p>GLFW uses the <code>GLX_ARB_framebuffer_sRGB</code> and <code>GLX_EXT_framebuffer_sRGB</code> extensions to provide support for sRGB framebuffers. Where both of these extensions are unavailable, the <code>GLFW_SRGB_CAPABLE</code> hint will have no effect.</p>
+<h1><a class="anchor" id="compat_wgl"></a>
+WGL extensions</h1>
+<p>The WGL API is used to create OpenGL contexts on Microsoft Windows and other implementations of the Win32 API, such as Wine.</p>
+<p>GLFW uses either the <code>WGL_EXT_extension_string</code> or the <code>WGL_ARB_extension_string</code> extension to check for the presence of all other WGL extensions listed below. If both are available, the EXT one is preferred. If neither is available, no other extensions are used and many GLFW features related to context creation will have no effect or cause errors when used.</p>
+<p>GLFW uses the <code>WGL_EXT_swap_control</code> extension to provide vertical retrace synchronization (or <em>vsync</em>). Where this extension is unavailable, calling <a class="el" href="group__context.html#ga6d4e0cdf151b5e579bd67f13202994ed">glfwSwapInterval</a> will have no effect.</p>
+<p>GLFW uses the <code>WGL_ARB_pixel_format</code> and <code>WGL_ARB_multisample</code> extensions to create contexts with multisampling anti-aliasing. Where these extensions are unavailable, the <code>GLFW_SAMPLES</code> hint will have no effect.</p>
+<p>GLFW uses the <code>WGL_ARB_create_context</code> extension when available, even when creating OpenGL contexts of version 2.1 and below. Where this extension is unavailable, the <code>GLFW_CONTEXT_VERSION_MAJOR</code> and <code>GLFW_CONTEXT_VERSION_MINOR</code> hints will only be partially supported, the <code>GLFW_OPENGL_DEBUG_CONTEXT</code> hint will have no effect, and setting the <code>GLFW_OPENGL_PROFILE</code> or <code>GLFW_OPENGL_FORWARD_COMPAT</code> hints to <code>GLFW_TRUE</code> will cause <a class="el" href="group__window.html#ga5c336fddf2cbb5b92f65f10fb6043344">glfwCreateWindow</a> to fail.</p>
+<p>GLFW uses the <code>WGL_ARB_create_context_profile</code> extension to provide support for context profiles. Where this extension is unavailable, setting the <code>GLFW_OPENGL_PROFILE</code> hint to anything but <code>GLFW_OPENGL_ANY_PROFILE</code> will cause <a class="el" href="group__window.html#ga5c336fddf2cbb5b92f65f10fb6043344">glfwCreateWindow</a> to fail.</p>
+<p>GLFW uses the <code>WGL_ARB_context_flush_control</code> extension to provide control over whether a context is flushed when it is released (made non-current). Where this extension is unavailable, the <code>GLFW_CONTEXT_RELEASE_BEHAVIOR</code> hint will have no effect and the context will always be flushed when released.</p>
+<p>GLFW uses the <code>WGL_ARB_framebuffer_sRGB</code> and <code>WGL_EXT_framebuffer_sRGB</code> extensions to provide support for sRGB framebuffers. Where both of these extension are unavailable, the <code>GLFW_SRGB_CAPABLE</code> hint will have no effect.</p>
+<h1><a class="anchor" id="compat_osx"></a>
+OpenGL on macOS</h1>
+<p>Support for OpenGL 3.2 and above was introduced with OS X 10.7 and even then only forward-compatible, core profile contexts are supported. Support for OpenGL 4.1 was introduced with OS X 10.9, also limited to forward-compatible, core profile contexts. There is also still no mechanism for requesting debug contexts or no-error contexts. Versions of Mac OS X earlier than 10.7 support at most OpenGL version 2.1.</p>
+<p>Because of this, on OS X 10.7 and later, the <code>GLFW_CONTEXT_VERSION_MAJOR</code> and <code>GLFW_CONTEXT_VERSION_MINOR</code> hints will cause <a class="el" href="group__window.html#ga5c336fddf2cbb5b92f65f10fb6043344">glfwCreateWindow</a> to fail if given version 3.0 or 3.1. The <code>GLFW_OPENGL_FORWARD_COMPAT</code> hint must be set to <code>GLFW_TRUE</code> and the <code>GLFW_OPENGL_PROFILE</code> hint must be set to <code>GLFW_OPENGL_CORE_PROFILE</code> when creating OpenGL 3.2 and later contexts. The <code>GLFW_OPENGL_DEBUG_CONTEXT</code> and <code>GLFW_CONTEXT_NO_ERROR</code> hints are ignored.</p>
+<p>Also, on Mac OS X 10.6 and below, the <code>GLFW_CONTEXT_VERSION_MAJOR</code> and <code>GLFW_CONTEXT_VERSION_MINOR</code> hints will fail if given a version above 2.1, setting the <code>GLFW_OPENGL_PROFILE</code> or <code>GLFW_OPENGL_FORWARD_COMPAT</code> hints to a non-default value will cause <a class="el" href="group__window.html#ga5c336fddf2cbb5b92f65f10fb6043344">glfwCreateWindow</a> to fail and the <code>GLFW_OPENGL_DEBUG_CONTEXT</code> hint is ignored.</p>
+<h1><a class="anchor" id="compat_vulkan"></a>
+Vulkan loader and API</h1>
+<p>By default, GLFW uses the standard system-wide Vulkan loader to access the Vulkan API on all platforms except macOS. This is installed by both graphics drivers and Vulkan SDKs. If either the loader or at least one minimally functional ICD is missing, <a class="el" href="group__vulkan.html#ga2e7f30931e02464b5bc8d0d4b6f9fe2b">glfwVulkanSupported</a> will return <code>GLFW_FALSE</code> and all other Vulkan-related functions will fail with an <a class="el" href="group__errors.html#ga56882b290db23261cc6c053c40c2d08e">GLFW_API_UNAVAILABLE</a> error.</p>
+<h1><a class="anchor" id="compat_wsi"></a>
+Vulkan WSI extensions</h1>
+<p>The Vulkan WSI extensions are used to create Vulkan surfaces for GLFW windows on all supported platforms.</p>
+<p>GLFW uses the <code>VK_KHR_surface</code> and <code>VK_KHR_win32_surface</code> extensions to create surfaces on Microsoft Windows. If any of these extensions are not available, <a class="el" href="group__vulkan.html#ga1abcbe61033958f22f63ef82008874b1">glfwGetRequiredInstanceExtensions</a> will return an empty list and window surface creation will fail.</p>
+<p>GLFW uses the <code>VK_KHR_surface</code> and either the <code>VK_MVK_macos_surface</code> or <code>VK_EXT_metal_surface</code> extensions to create surfaces on macOS. If any of these extensions are not available, <a class="el" href="group__vulkan.html#ga1abcbe61033958f22f63ef82008874b1">glfwGetRequiredInstanceExtensions</a> will return an empty list and window surface creation will fail.</p>
+<p>GLFW uses the <code>VK_KHR_surface</code> and either the <code>VK_KHR_xlib_surface</code> or <code>VK_KHR_xcb_surface</code> extensions to create surfaces on X11. If <code>VK_KHR_surface</code> or both <code>VK_KHR_xlib_surface</code> and <code>VK_KHR_xcb_surface</code> are not available, <a class="el" href="group__vulkan.html#ga1abcbe61033958f22f63ef82008874b1">glfwGetRequiredInstanceExtensions</a> will return an empty list and window surface creation will fail.</p>
+<p>GLFW uses the <code>VK_KHR_surface</code> and <code>VK_KHR_wayland_surface</code> extensions to create surfaces on Wayland.

+<h1><a class="anchor" id="compile_cmake"></a>
+Using CMake</h1>
+<p>GLFW uses <a href="https://cmake.org/">CMake</a> to generate project files or makefiles for a particular development environment. If you are on a Unix-like system such as Linux or FreeBSD or have a package system like Fink, MacPorts, Cygwin or Homebrew, you can install its CMake package. If not, you can download installers for Windows and macOS from the <a href="https://cmake.org/">CMake website</a>.</p>
+<dl class="section note"><dt>Note</dt><dd>CMake only generates project files or makefiles. It does not compile the actual GLFW library. To compile GLFW, first generate these files for your chosen development environment and then use them to compile the actual GLFW library.</dd></dl>
+<h2><a class="anchor" id="compile_deps"></a>
+Dependencies</h2>
+<p>Once you have installed CMake, make sure that all other dependencies are available. On some platforms, GLFW needs a few additional packages to be installed. See the section for your chosen platform and development environment below.</p>
+<h3><a class="anchor" id="compile_deps_msvc"></a>
+Dependencies for Visual C++ on Windows</h3>
+<p>The Windows SDK bundled with Visual C++ already contains all the necessary headers, link libraries and tools except for CMake. Move on to <a class="el" href="compile_guide.html#compile_generate">Generating build files with CMake</a>.</p>
+<h3><a class="anchor" id="compile_deps_mingw"></a>
+Dependencies for MinGW or MinGW-w64 on Windows</h3>
+<p>Both the MinGW and the MinGW-w64 packages already contain all the necessary headers, link libraries and tools except for CMake. Move on to <a class="el" href="compile_guide.html#compile_generate">Generating build files with CMake</a>.</p>
+<h3><a class="anchor" id="compile_deps_mingw_cross"></a>
+Dependencies for MinGW or MinGW-w64 cross-compilation</h3>
+<p>Both Cygwin and many Linux distributions have MinGW or MinGW-w64 packages. For example, Cygwin has the <code>mingw64-i686-gcc</code> and <code>mingw64-x86_64-gcc</code> packages for 32- and 64-bit version of MinGW-w64, while Debian GNU/Linux and derivatives like Ubuntu have the <code>mingw-w64</code> package for both.</p>
+<p>GLFW has CMake toolchain files in the <code>CMake/</code> directory that set up cross-compilation of Windows binaries. To use these files you add an option when running <code>cmake</code> to generate the project files or makefiles:</p>
+<div class="fragment"><div class="line">cmake -DCMAKE_TOOLCHAIN_FILE=&lt;toolchain-file&gt; .</div>
+</div><!-- fragment --><p>The exact toolchain file to use depends on the prefix used by the MinGW or MinGW-w64 binaries on your system. You can usually see this in the /usr directory. For example, both the Debian/Ubuntu and Cygwin MinGW-w64 packages have <code>/usr/x86_64-w64-mingw32</code> for the 64-bit compilers, so the correct invocation would be:</p>
+<div class="fragment"><div class="line">cmake -DCMAKE_TOOLCHAIN_FILE=CMake/x86_64-w64-mingw32.cmake .</div>
+</div><!-- fragment --><p>For more details see the article <a href="https://gitlab.kitware.com/cmake/community/wikis/doc/cmake/CrossCompiling">CMake Cross Compiling</a> on the CMake wiki.</p>
+<p>Once you have this set up, move on to <a class="el" href="compile_guide.html#compile_generate">Generating build files with CMake</a>.</p>
+<h3><a class="anchor" id="compile_deps_xcode"></a>
+Dependencies for Xcode on macOS</h3>
+<p>Xcode comes with all necessary tools except for CMake. The required headers and libraries are included in the core macOS frameworks. Xcode can be downloaded from the Mac App Store or from the ADC Member Center.</p>
+<p>Once you have Xcode installed, move on to <a class="el" href="compile_guide.html#compile_generate">Generating build files with CMake</a>.</p>
+<h3><a class="anchor" id="compile_deps_x11"></a>
+Dependencies for Linux and X11</h3>
+<p>To compile GLFW for X11, you need to have the X11 packages installed, as well as the basic development tools like GCC and make. For example, on Ubuntu and other distributions based on Debian GNU/Linux, you need to install the <code>xorg-dev</code> package, which pulls in all X.org header packages.</p>
+<p>Once you have installed the necessary packages, move on to <a class="el" href="compile_guide.html#compile_generate">Generating build files with CMake</a>.</p>
+<h3><a class="anchor" id="compile_deps_wayland"></a>
+Dependencies for Linux and Wayland</h3>
+<p>To compile GLFW for Wayland, you need to have the Wayland packages installed, as well as the basic development tools like GCC and make. For example, on Ubuntu and other distributions based on Debian GNU/Linux, you need to install the <code>libwayland-dev</code> package, which contains all Wayland headers and pulls in wayland-scanner, as well as the <code>wayland-protocols</code> and <code>extra-cmake-modules</code> packages.</p>
+<p>Once you have installed the necessary packages, move on to <a class="el" href="compile_guide.html#compile_generate">Generating build files with CMake</a>.</p>
+<h2><a class="anchor" id="compile_deps_osmesa"></a>
+Dependencies for Linux and OSMesa</h2>
+<p>To compile GLFW for OSMesa, you need to install the OSMesa library and header packages. For example, on Ubuntu and other distributions based on Debian GNU/Linux, you need to install the <code>libosmesa6-dev</code> package. The OSMesa library is required at runtime for context creation and is loaded on demand.</p>
+<p>Once you have installed the necessary packages, move on to <a class="el" href="compile_guide.html#compile_generate">Generating build files with CMake</a>.</p>
+<h2><a class="anchor" id="compile_generate"></a>
+Generating build files with CMake</h2>
+<p>Once you have all necessary dependencies it is time to generate the project files or makefiles for your development environment. CMake needs to know two paths for this: the path to the <em>root</em> directory of the GLFW source tree (i.e. <em>not</em> the <code>src</code> subdirectory) and the target path for the generated files and compiled binaries. If these are the same, it is called an in-tree build, otherwise it is called an out-of-tree build.</p>
+<p>One of several advantages of out-of-tree builds is that you can generate files and compile for different development environments using a single source tree.</p>
+<dl class="section note"><dt>Note</dt><dd>This section is about generating the project files or makefiles necessary to compile the GLFW library, not about compiling the actual library.</dd></dl>
+<h3><a class="anchor" id="compile_generate_cli"></a>
+Generating files with the CMake command-line tool</h3>
+<p>To make an in-tree build, enter the <em>root</em> directory of the GLFW source tree (i.e. <em>not</em> the <code>src</code> subdirectory) and run CMake. The current directory is used as target path, while the path provided as an argument is used to find the source tree.</p>
+<div class="fragment"><div class="line">cd &lt;glfw-root-dir&gt;</div>
+<div class="line">cmake .</div>
+</div><!-- fragment --><p>To make an out-of-tree build, make a directory outside of the source tree, enter it and run CMake with the (relative or absolute) path to the root of the source tree as an argument.</p>
+<div class="fragment"><div class="line">mkdir glfw-build</div>
+<div class="line">cd glfw-build</div>
+<div class="line">cmake &lt;glfw-root-dir&gt;</div>
+</div><!-- fragment --><p>Once you have generated the project files or makefiles for your chosen development environment, move on to <a class="el" href="compile_guide.html#compile_compile">Compiling the library</a>.</p>
+<h3><a class="anchor" id="compile_generate_gui"></a>
+Generating files with the CMake GUI</h3>
+<p>If you are using the GUI version, choose the root of the GLFW source tree as source location and the same directory or another, empty directory as the destination for binaries. Choose <em>Configure</em>, change any options you wish to, <em>Configure</em> again to let the changes take effect and then <em>Generate</em>.</p>
+<p>Once you have generated the project files or makefiles for your chosen development environment, move on to <a class="el" href="compile_guide.html#compile_compile">Compiling the library</a>.</p>
+<h2><a class="anchor" id="compile_compile"></a>
+Compiling the library</h2>
+<p>You should now have all required dependencies and the project files or makefiles necessary to compile GLFW. Go ahead and compile the actual GLFW library with these files, as you would with any other project.</p>
+<p>Once the GLFW library is compiled, you are ready to build your applications, linking it to the GLFW library. See <a class="el" href="build_guide.html">Building applications</a> for more information.</p>
+<h2><a class="anchor" id="compile_options"></a>
+CMake options</h2>
+<p>The CMake files for GLFW provide a number of options, although not all are available on all supported platforms. Some of these are de facto standards among projects using CMake and so have no <code>GLFW_</code> prefix.</p>
+<p>If you are using the GUI version of CMake, these are listed and can be changed from there. If you are using the command-line version of CMake you can use the <code>ccmake</code> ncurses GUI to set options. Some package systems like Ubuntu and other distributions based on Debian GNU/Linux have this tool in a separate <code>cmake-curses-gui</code> package.</p>
+<p>Finally, if you don't want to use any GUI, you can set options from the <code>cmake</code> command-line with the <code>-D</code> flag.</p>
+<div class="fragment"><div class="line">cmake -DBUILD_SHARED_LIBS=ON .</div>
+</div><!-- fragment --><h3><a class="anchor" id="compile_options_shared"></a>
+Shared CMake options</h3>
+<p><a class="anchor" id="BUILD_SHARED_LIBS"></a><b>BUILD_SHARED_LIBS</b> determines whether GLFW is built as a static library or as a DLL / shared library / dynamic library.</p>
+<p><a class="anchor" id="GLFW_BUILD_EXAMPLES"></a><b>GLFW_BUILD_EXAMPLES</b> determines whether the GLFW examples are built along with the library.</p>
+<p><a class="anchor" id="GLFW_BUILD_TESTS"></a><b>GLFW_BUILD_TESTS</b> determines whether the GLFW test programs are built along with the library.</p>
+<p><a class="anchor" id="GLFW_BUILD_DOCS"></a><b>GLFW_BUILD_DOCS</b> determines whether the GLFW documentation is built along with the library.</p>
+<p><a class="anchor" id="GLFW_VULKAN_STATIC"></a><b>GLFW_VULKAN_STATIC</b> determines whether to use the Vulkan loader linked directly with the application.</p>
+<h3><a class="anchor" id="compile_options_win32"></a>
+Windows specific CMake options</h3>
+<p><a class="anchor" id="USE_MSVC_RUNTIME_LIBRARY_DLL"></a><b>USE_MSVC_RUNTIME_LIBRARY_DLL</b> determines whether to use the DLL version or the static library version of the Visual C++ runtime library. If set to <code>ON</code>, the DLL version of the Visual C++ library is used.</p>
+<p><a class="anchor" id="GLFW_USE_HYBRID_HPG"></a><b>GLFW_USE_HYBRID_HPG</b> determines whether to export the <code>NvOptimusEnablement</code> and <code>AmdPowerXpressRequestHighPerformance</code> symbols, which force the use of the high-performance GPU on Nvidia Optimus and AMD PowerXpress systems. These symbols need to be exported by the EXE to be detected by the driver, so the override will not work if GLFW is built as a DLL.</p>
+<h1><a class="anchor" id="compile_manual"></a>
+Compiling GLFW manually</h1>
+<p>If you wish to compile GLFW without its CMake build environment then you will have to do at least some of the platform detection yourself. GLFW needs a configuration macro to be defined in order to know what window system it's being compiled for and also has optional, platform-specific ones for various features.</p>
+<p>When building with CMake, the <code>glfw_config.h</code> configuration header is generated based on the current platform and CMake options. The GLFW CMake environment defines <b>GLFW_USE_CONFIG_H</b>, which causes this header to be included by <code>internal.h</code>. Without this macro, GLFW will expect the necessary configuration macros to be defined on the command-line.</p>
+<p>The window creation API is used to create windows, handle input, monitors, gamma ramps and clipboard. The options are:</p>
+<ul>
+<li><b>_GLFW_COCOA</b> to use the Cocoa frameworks</li>
+<li><b>_GLFW_WIN32</b> to use the Win32 API</li>
+<li><b>_GLFW_X11</b> to use the X Window System</li>
+<li><b>_GLFW_WAYLAND</b> to use the Wayland API (experimental and incomplete)</li>
+<li><b>_GLFW_OSMESA</b> to use the OSMesa API (headless and non-interactive)</li>
+</ul>
+<p>If you are building GLFW as a shared library / dynamic library / DLL then you must also define <b>_GLFW_BUILD_DLL</b>. Otherwise, you must not define it.</p>
+<p>If you are linking the Vulkan loader directly with your application then you must also define <b>_GLFW_VULKAN_STATIC</b>. Otherwise, GLFW will attempt to use the external version.</p>
+<p>If you are using a custom name for the Vulkan, EGL, GLX, OSMesa, OpenGL, GLESv1 or GLESv2 library, you can override the default names by defining those you need of <b>_GLFW_VULKAN_LIBRARY</b>, <b>_GLFW_EGL_LIBRARY</b>, <b>_GLFW_GLX_LIBRARY</b>, <b>_GLFW_OSMESA_LIBRARY</b>, <b>_GLFW_OPENGL_LIBRARY</b>, <b>_GLFW_GLESV1_LIBRARY</b> and <b>_GLFW_GLESV2_LIBRARY</b>. Otherwise, GLFW will use the built-in default names.</p>
+<p>For the EGL context creation API, the following options are available:</p>
+<ul>
+<li><b>_GLFW_USE_EGLPLATFORM_H</b> to use an existing <code>EGL/eglplatform.h</code> header file for native handle types (fallback)</li>
+</ul>
+<dl class="section note"><dt>Note</dt><dd>None of the <a class="el" href="build_guide.html#build_macros">GLFW header option macros</a> may be defined during the compilation of GLFW. If you define any of these in your build files, make sure they are not applied to the GLFW sources. </dd></dl>

+OpenGL and OpenGL ES extensions</h1>
+<p>One of the benefits of OpenGL and OpenGL ES is their extensibility. Hardware vendors may include extensions in their implementations that extend the API before that functionality is included in a new version of the OpenGL or OpenGL ES specification, and some extensions are never included and remain as extensions until they become obsolete.</p>
+<p>An extension is defined by:</p>
+<ul>
+<li>An extension name (e.g. <code>GL_ARB_debug_output</code>)</li>
+<li>New OpenGL tokens (e.g. <code>GL_DEBUG_SEVERITY_HIGH_ARB</code>)</li>
+<li>New OpenGL functions (e.g. <code>glGetDebugMessageLogARB</code>)</li>
+</ul>
+<p>Note the <code>ARB</code> affix, which stands for Architecture Review Board and is used for official extensions. The extension above was created by the ARB, but there are many different affixes, like <code>NV</code> for Nvidia and <code>AMD</code> for, well, AMD. Any group may also use the generic <code>EXT</code> affix. Lists of extensions, together with their specifications, can be found at the <a href="https://www.opengl.org/registry/">OpenGL Registry</a> and <a href="https://www.khronos.org/registry/gles/">OpenGL ES Registry</a>.</p>
+<h2><a class="anchor" id="context_glext_auto"></a>
+Loading extension with a loader library</h2>
+<p>An extension loader library is the easiest and best way to access both OpenGL and OpenGL ES extensions and modern versions of the core OpenGL or OpenGL ES APIs. They will take care of all the details of declaring and loading everything you need. One such library is <a href="https://github.com/Dav1dde/glad">glad</a> and there are several others.</p>
+<p>The following example will use glad but all extension loader libraries work similarly.</p>
+<p>First you need to generate the source files using the glad Python script. This example generates a loader for any version of OpenGL, which is the default for both GLFW and glad, but loaders for OpenGL ES, as well as loaders for specific API versions and extension sets can be generated. The generated files are written to the <code>output</code> directory.</p>
+<div class="fragment"><div class="line">python main.py --generator c --no-loader --out-path output</div>
+</div><!-- fragment --><p>The <code>--no-loader</code> option is added because GLFW already provides a function for loading OpenGL and OpenGL ES function pointers, one that automatically uses the selected context creation API, and glad can call this instead of having to implement its own. There are several other command-line options as well. See the glad documentation for details.</p>
+<p>Add the generated <code>output/src/glad.c</code>, <code>output/include/glad/glad.h</code> and <code>output/include/KHR/khrplatform.h</code> files to your build. Then you need to include the glad header file, which will replace the OpenGL header of your development environment. By including the glad header before the GLFW header, it suppresses the development environment's OpenGL or OpenGL ES header.</p>
+<div class="fragment"><div class="line"><span class="preprocessor">#include &lt;glad/glad.h&gt;</span></div>
+<div class="line"><span class="preprocessor">#include &lt;<a class="code" href="glfw3_8h.html">GLFW/glfw3.h</a>&gt;</span></div>
+</div><!-- fragment --><p>Finally you need to initialize glad once you have a suitable current context.</p>
+<div class="fragment"><div class="line">window = <a class="code" href="group__window.html#ga5c336fddf2cbb5b92f65f10fb6043344">glfwCreateWindow</a>(640, 480, <span class="stringliteral">&quot;My Window&quot;</span>, NULL, NULL);</div>

+Loading extensions manually</h2>
+<p><b>Do not use this technique</b> unless it is absolutely necessary. An <a class="el" href="context_guide.html#context_glext_auto">extension loader library</a> will save you a ton of tedious, repetitive, error prone work.</p>
+<p>To use a certain extension, you must first check whether the context supports that extension and then, if it introduces new functions, retrieve the pointers to those functions. GLFW provides <a class="el" href="group__context.html#ga87425065c011cef1ebd6aac75e059dfa">glfwExtensionSupported</a> and <a class="el" href="group__context.html#ga35f1837e6f666781842483937612f163">glfwGetProcAddress</a> for manual loading of extensions and new API functions.</p>
+<p>This section will demonstrate manual loading of OpenGL extensions. The loading of OpenGL ES extensions is identical except for the name of the extension header.</p>
+<h3><a class="anchor" id="context_glext_header"></a>
+The glext.h header</h3>
+<p>The <code>glext.h</code> extension header is a continually updated file that defines the interfaces for all OpenGL extensions. The latest version of this can always be found at the <a href="https://www.opengl.org/registry/">OpenGL Registry</a>. There are also extension headers for the various versions of OpenGL ES at the <a href="https://www.khronos.org/registry/gles/">OpenGL ES Registry</a>. It it strongly recommended that you use your own copy of the extension header, as the one included in your development environment may be several years out of date and may not include the extensions you wish to use.</p>
+<p>The header defines function pointer types for all functions of all extensions it supports. These have names like <code>PFNGLGETDEBUGMESSAGELOGARBPROC</code> (for <code>glGetDebugMessageLogARB</code>), i.e. the name is made uppercase and <code>PFN</code> (pointer to function) and <code>PROC</code> (procedure) are added to the ends.</p>
+<p>To include the extension header, define <a class="el" href="build_guide.html#GLFW_INCLUDE_GLEXT">GLFW_INCLUDE_GLEXT</a> before including the GLFW header.</p>
+<div class="fragment"><div class="line"><span class="preprocessor">#define GLFW_INCLUDE_GLEXT</span></div>
+<div class="line"><span class="preprocessor">#include &lt;GLFW/glfw3.h&gt;</span></div>
+</div><!-- fragment --><h3><a class="anchor" id="context_glext_string"></a>
+Checking for extensions</h3>
+<p>A given machine may not actually support the extension (it may have older drivers or a graphics card that lacks the necessary hardware features), so it is necessary to check at run-time whether the context supports the extension. This is done with <a class="el" href="group__context.html#ga87425065c011cef1ebd6aac75e059dfa">glfwExtensionSupported</a>.</p>
+<div class="fragment"><div class="line"><span class="keywordflow">if</span> (<a class="code" href="group__context.html#ga87425065c011cef1ebd6aac75e059dfa">glfwExtensionSupported</a>(<span class="stringliteral">&quot;GL_ARB_debug_output&quot;</span>))</div>
+<div class="line">{</div>
+<div class="line">    <span class="comment">// The extension is supported by the current context</span></div>
+<div class="line">}</div>
+</div><!-- fragment --><p>The argument is a null terminated ASCII string with the extension name. If the extension is supported, <a class="el" href="group__context.html#ga87425065c011cef1ebd6aac75e059dfa">glfwExtensionSupported</a> returns <code>GLFW_TRUE</code>, otherwise it returns <code>GLFW_FALSE</code>.</p>
+<h3><a class="anchor" id="context_glext_proc"></a>
+Fetching function pointers</h3>
+<p>Many extensions, though not all, require the use of new OpenGL functions. These functions often do not have entry points in the client API libraries of your operating system, making it necessary to fetch them at run time. You can retrieve pointers to these functions with <a class="el" href="group__context.html#ga35f1837e6f666781842483937612f163">glfwGetProcAddress</a>.</p>
+<div class="fragment"><div class="line">PFNGLGETDEBUGMESSAGELOGARBPROC pfnGetDebugMessageLog = <a class="code" href="group__context.html#ga35f1837e6f666781842483937612f163">glfwGetProcAddress</a>(<span class="stringliteral">&quot;glGetDebugMessageLogARB&quot;</span>);</div>
+</div><!-- fragment --><p>In general, you should avoid giving the function pointer variables the (exact) same name as the function, as this may confuse your linker. Instead, you can use a different prefix, like above, or some other naming scheme.</p>

Like the character callback, the character with modifiers callback deals with characters and is keyboard layout dependent. Characters do not map 1:1 to physical keys, as a key may produce zero, one or more characters. If you want to know whether a specific physical key was pressed or released, see the <a class="el" href="group__input.html#ga1caf18159767e761185e49a3be019f8d">key callback</a> instead.</p>

+<p>See <a class="el" href="input_guide.html#input_key">key input</a> for how these are used.</p>
+<p>These key codes are inspired by the <em>USB HID Usage Tables v1.12</em> (p. 53-60), but re-arranged to map to 7-bit ASCII for printable keys (function keys are put in the 256+ range).</p>
+<p>The naming of the key codes follow these rules:</p><ul>
+<li>The US keyboard layout is used</li>
+<li>Names of printable alpha-numeric characters are used (e.g. "A", "R", "3", etc.)</li>
+<li>For non-alphanumeric characters, Unicode:ish names are used (e.g. "COMMA", "LEFT_SQUARE_BRACKET", etc.). Note that some names do not correspond to the Unicode standard (usually for brevity)</li>
+<li>Keys that lack a clear US mapping are named "WORLD_x"</li>
+<li>For non-printable keys, custom names are used (e.g. "F4", "BACKSPACE", etc.) </li>
+</ul>

+<p><b>By using the native access functions you assert that you know what you're doing and how to fix problems caused by using them. If you don't, you shouldn't be using them.</b></p>
+<p>Before the inclusion of <a class="el" href="glfw3native_8h.html">glfw3native.h</a>, you may define zero or more window system API macro and zero or more context creation API macros.</p>
+<p>The chosen backends must match those the library was compiled for. Failure to do this will cause a link-time error.</p>
+<p>The available window API macros are:</p><ul>
+<li><code>GLFW_EXPOSE_NATIVE_WIN32</code></li>
+<li><code>GLFW_EXPOSE_NATIVE_COCOA</code></li>
+<li><code>GLFW_EXPOSE_NATIVE_X11</code></li>
+<li><code>GLFW_EXPOSE_NATIVE_WAYLAND</code></li>
+</ul>
+<p>The available context API macros are:</p><ul>
+<li><code>GLFW_EXPOSE_NATIVE_WGL</code></li>
+<li><code>GLFW_EXPOSE_NATIVE_NSGL</code></li>
+<li><code>GLFW_EXPOSE_NATIVE_GLX</code></li>
+<li><code>GLFW_EXPOSE_NATIVE_EGL</code></li>
+<li><code>GLFW_EXPOSE_NATIVE_OSMESA</code></li>
+</ul>
+<p>These macros select which of the native access functions that are declared and which platform-specific headers to include. It is then up your (by definition platform-specific) code to handle which of these should be defined. </p>

+<p>This function creates a window and its associated OpenGL or OpenGL ES context. Most of the options controlling how the window and its context should be created are specified with <a class="el" href="window_guide.html#window_hints">window hints</a>.</p>
+<p>Successful creation does not change which context is current. Before you can use the newly created context, you need to <a class="el" href="context_guide.html#context_current">make it current</a>. For information about the <code>share</code> parameter, see <a class="el" href="context_guide.html#context_sharing">Context object sharing</a>.</p>
+<p>The created window, framebuffer and context may differ from what you requested, as not all parameters and hints are <a class="el" href="window_guide.html#window_hints_hard">hard constraints</a>. This includes the size of the window, especially for full screen windows. To query the actual attributes of the created window, framebuffer and context, see <a class="el" href="group__window.html#gacccb29947ea4b16860ebef42c2cb9337">glfwGetWindowAttrib</a>, <a class="el" href="group__window.html#gaeea7cbc03373a41fb51cfbf9f2a5d4c6">glfwGetWindowSize</a> and <a class="el" href="group__window.html#ga0e2637a4161afb283f5300c7f94785c9">glfwGetFramebufferSize</a>.</p>
+<p>To create a full screen window, you need to specify the monitor the window will cover. If no monitor is specified, the window will be windowed mode. Unless you have a way for the user to choose a specific monitor, it is recommended that you pick the primary monitor. For more information on how to query connected monitors, see <a class="el" href="monitor_guide.html#monitor_monitors">Retrieving monitors</a>.</p>
+<p>For full screen windows, the specified size becomes the resolution of the window's <em>desired video mode</em>. As long as a full screen window is not iconified, the supported video mode most closely matching the desired video mode is set for the specified monitor. For more information about full screen windows, including the creation of so called <em>windowed full screen</em> or <em>borderless full screen</em> windows, see <a class="el" href="window_guide.html#window_windowed_full_screen">"Windowed full screen" windows</a>.</p>
+<p>Once you have created the window, you can switch it between windowed and full screen mode with <a class="el" href="group__window.html#ga81c76c418af80a1cce7055bccb0ae0a7">glfwSetWindowMonitor</a>. This will not affect its OpenGL or OpenGL ES context.</p>
+<p>By default, newly created windows use the placement recommended by the window system. To create the window at a specific position, make it initially invisible using the <a class="el" href="window_guide.html#GLFW_VISIBLE_hint">GLFW_VISIBLE</a> window hint, set its <a class="el" href="window_guide.html#window_pos">position</a> and then <a class="el" href="window_guide.html#window_hide">show</a> it.</p>
+<p>As long as at least one full screen window is not iconified, the screensaver is prohibited from starting.</p>
+<p>Window systems put limits on window sizes. Very large or very small window dimensions may be overridden by the window system on creation. Check the actual <a class="el" href="window_guide.html#window_size">size</a> after creation.</p>
+<p>The <a class="el" href="window_guide.html#buffer_swap">swap interval</a> is not set during window creation and the initial value may vary depending on driver settings and defaults.</p>

+<dd>
+<b>Windows:</b> If the executable has an icon resource named <code>GLFW_ICON,</code> it will be set as the initial icon for the window. If no such icon is present, the <code>IDI_APPLICATION</code> icon will be used instead. To set a different icon, see <a class="el" href="group__window.html#gadd7ccd39fe7a7d1f0904666ae5932dc5">glfwSetWindowIcon</a>.</dd>
+<dd>
+<b>Windows:</b> The context to share resources with must not be current on any other thread.</dd>
+<dd>
+<b>macOS:</b> The OS only supports forward-compatible core profile contexts for OpenGL versions 3.2 and later. Before creating an OpenGL context of version 3.2 or later you must set the <a class="el" href="window_guide.html#GLFW_OPENGL_FORWARD_COMPAT_hint">GLFW_OPENGL_FORWARD_COMPAT</a> and <a class="el" href="window_guide.html#GLFW_OPENGL_PROFILE_hint">GLFW_OPENGL_PROFILE</a> hints accordingly. OpenGL 3.0 and 3.1 contexts are not supported at all on macOS.</dd>
+<dd>
+<b>macOS:</b> The GLFW window has no icon, as it is not a document window, but the dock icon will be the same as the application bundle's icon. For more information on bundles, see the <a href="https://developer.apple.com/library/mac/documentation/CoreFoundation/Conceptual/CFBundles/">Bundle Programming Guide</a> in the Mac Developer Library.</dd>
+<dd>
+<b>macOS:</b> The first time a window is created the menu bar is created. If GLFW finds a <code>MainMenu.nib</code> it is loaded and assumed to contain a menu bar. Otherwise a minimal menu bar is created manually with common commands like Hide, Quit and About. The About entry opens a minimal about dialog with information from the application's bundle. Menu bar creation can be disabled entirely with the <a class="el" href="group__init.html#ga71e0b4ce2f2696a84a9b8c5e12dc70cf">GLFW_COCOA_MENUBAR</a> init hint.</dd>
+<dd>
+<b>macOS:</b> On OS X 10.10 and later the window frame will not be rendered at full resolution on Retina displays unless the <a class="el" href="window_guide.html#GLFW_COCOA_RETINA_FRAMEBUFFER_hint">GLFW_COCOA_RETINA_FRAMEBUFFER</a> hint is <code>GLFW_TRUE</code> and the <code>NSHighResolutionCapable</code> key is enabled in the application bundle's <code>Info.plist</code>. For more information, see <a href="https://developer.apple.com/library/mac/documentation/GraphicsAnimation/Conceptual/HighResolutionOSX/Explained/Explained.html">High Resolution Guidelines for OS X</a> in the Mac Developer Library. The GLFW test and example programs use a custom <code>Info.plist</code> template for this, which can be found as <code>CMake/MacOSXBundleInfo.plist.in</code> in the source tree.</dd>
+<dd>
+<b>macOS:</b> When activating frame autosaving with <a class="el" href="window_guide.html#GLFW_COCOA_FRAME_NAME_hint">GLFW_COCOA_FRAME_NAME</a>, the specified window size and position may be overridden by previously saved values.</dd>
+<dd>
+<b>X11:</b> Some window managers will not respect the placement of initially hidden windows.</dd>
+<dd>
+<b>X11:</b> Due to the asynchronous nature of X11, it may take a moment for a window to reach its requested state. This means you may not be able to query the final size, position or other attributes directly after window creation.</dd>
+<dd>
+<b>X11:</b> The class part of the <code>WM_CLASS</code> window property will by default be set to the window title passed to this function. The instance part will use the contents of the <code>RESOURCE_NAME</code> environment variable, if present and not empty, or fall back to the window title. Set the <a class="el" href="window_guide.html#GLFW_X11_CLASS_NAME_hint">GLFW_X11_CLASS_NAME</a> and <a class="el" href="window_guide.html#GLFW_X11_INSTANCE_NAME_hint">GLFW_X11_INSTANCE_NAME</a> window hints to override this.</dd>
+<dd>
+<b>Wayland:</b> Compositors should implement the xdg-decoration protocol for GLFW to decorate the window properly. If this protocol isn't supported, or if the compositor prefers client-side decorations, a very simple fallback frame will be drawn using the wp_viewporter protocol. A compositor can still emit close, maximize or fullscreen events, using for instance a keybind mechanism. If neither of these protocols is supported, the window won't be decorated.</dd>
+<dd>
+<b>Wayland:</b> A full screen window will not attempt to change the mode, no matter what the requested size or refresh rate.</dd>
+<dd>
+<b>Wayland:</b> Screensaver inhibition requires the idle-inhibit protocol to be implemented in the user's compositor.</dd></dl>

+Introduction</h1>
+<p>GLFW is a free, Open Source, multi-platform library for OpenGL, OpenGL ES and Vulkan application development. It provides a simple, platform-independent API for creating windows, contexts and surfaces, reading input, handling events, etc.</p>
+<p><a class="el" href="news.html#news_33">Release notes for version 3.3</a> list new features, caveats and deprecations.</p>
+<p><a class="el" href="quick_guide.html">Getting started</a> is a guide for users new to GLFW. It takes you through how to write a small but complete program.</p>
+<p>There are guides for each section of the API:</p>
+<ul>
+<li><a class="el" href="intro_guide.html">Introduction to the API</a> – initialization, error handling and high-level design</li>
+<li><a class="el" href="window_guide.html">Window guide</a> – creating and working with windows and framebuffers</li>
+<li><a class="el" href="context_guide.html">Context guide</a> – working with OpenGL and OpenGL ES contexts</li>
+<li><a class="el" href="vulkan_guide.html">Vulkan guide</a> - working with Vulkan objects and extensions</li>
+<li><a class="el" href="monitor_guide.html">Monitor guide</a> – enumerating and working with monitors and video modes</li>
+<li><a class="el" href="input_guide.html">Input guide</a> – receiving events, polling and processing input</li>
+</ul>
+<p>Once you have written a program, see <a class="el" href="compile_guide.html">Compiling GLFW</a> and <a class="el" href="build_guide.html">Building applications</a>.</p>
+<p>The <a href="modules.html">reference documentation</a> provides more detailed information about specific functions.</p>
+<p><a class="el" href="moving_guide.html">Moving from GLFW 2 to 3</a> explains what has changed and how to update existing code to use the new API.</p>
+<p>There is a section on <a class="el" href="intro_guide.html#guarantees_limitations">Guarantees and limitations</a> for pointer lifetimes, reentrancy, thread safety, event order and backward and forward compatibility.</p>
+<p>The <a href="https://www.glfw.org/faq.html">FAQ</a> answers many common questions about the design, implementation and use of GLFW.</p>
+<p>Finally, <a class="el" href="compat_guide.html">Standards conformance</a> explains what APIs, standards and protocols GLFW uses and what happens when they are not present on a given machine.</p>
+<p>This documentation was generated with Doxygen. The sources for it are available in both the <a href="https://www.glfw.org/download.html">source distribution</a> and <a href="https://github.com/glfw/glfw">GitHub repository</a>. </p>

+<p>GLFW provides many kinds of input. While some can only be polled, like time, or only received via callbacks, like scrolling, many provide both callbacks and polling. Callbacks are more work to use than polling but is less CPU intensive and guarantees that you do not miss state changes.</p>
+<p>All input callbacks receive a window handle. By using the <a class="el" href="window_guide.html#window_userptr">window user pointer</a>, you can access non-global structures or objects from your callbacks.</p>
+<p>To get a better feel for how the various events callbacks behave, run the <code>events</code> test program. It register every callback supported by GLFW and prints out all arguments provided for every event, along with time and sequence information.</p>
+<h1><a class="anchor" id="events"></a>
+Event processing</h1>
+<p>GLFW needs to poll the window system for events both to provide input to the application and to prove to the window system that the application hasn't locked up. Event processing is normally done each frame after <a class="el" href="window_guide.html#buffer_swap">buffer swapping</a>. Even when you have no windows, event polling needs to be done in order to receive monitor and joystick connection events.</p>
+<p>There are three functions for processing pending events. <a class="el" href="group__window.html#ga37bd57223967b4211d60ca1a0bf3c832">glfwPollEvents</a>, processes only those events that have already been received and then returns immediately.</p>
+<div class="fragment"><div class="line"><a class="code" href="group__window.html#ga37bd57223967b4211d60ca1a0bf3c832">glfwPollEvents</a>();</div>
+</div><!-- fragment --><p>This is the best choice when rendering continuously, like most games do.</p>
+<p>If you only need to update the contents of the window when you receive new input, <a class="el" href="group__window.html#ga554e37d781f0a997656c26b2c56c835e">glfwWaitEvents</a> is a better choice.</p>
+<div class="fragment"><div class="line"><a class="code" href="group__window.html#ga554e37d781f0a997656c26b2c56c835e">glfwWaitEvents</a>();</div>
+</div><!-- fragment --><p>It puts the thread to sleep until at least one event has been received and then processes all received events. This saves a great deal of CPU cycles and is useful for, for example, editing tools.</p>
+<p>If you want to wait for events but have UI elements or other tasks that need periodic updates, <a class="el" href="group__window.html#ga605a178db92f1a7f1a925563ef3ea2cf">glfwWaitEventsTimeout</a> lets you specify a timeout.</p>
+<div class="fragment"><div class="line"><a class="code" href="group__window.html#ga605a178db92f1a7f1a925563ef3ea2cf">glfwWaitEventsTimeout</a>(0.7);</div>
+</div><!-- fragment --><p>It puts the thread to sleep until at least one event has been received, or until the specified number of seconds have elapsed. It then processes any received events.</p>
+<p>If the main thread is sleeping in <a class="el" href="group__window.html#ga554e37d781f0a997656c26b2c56c835e">glfwWaitEvents</a>, you can wake it from another thread by posting an empty event to the event queue with <a class="el" href="group__window.html#gab5997a25187e9fd5c6f2ecbbc8dfd7e9">glfwPostEmptyEvent</a>.</p>
+<div class="fragment"><div class="line"><a class="code" href="group__window.html#gab5997a25187e9fd5c6f2ecbbc8dfd7e9">glfwPostEmptyEvent</a>();</div>
+</div><!-- fragment --><p>Do not assume that callbacks will <em>only</em> be called in response to the above functions. While it is necessary to process events in one or more of the ways above, window systems that require GLFW to register callbacks of its own can pass events to GLFW in response to many window system function calls. GLFW will pass those events on to the application callbacks before returning.</p>
+<p>For example, on Windows the system function that <a class="el" href="group__window.html#ga371911f12c74c504dd8d47d832d095cb">glfwSetWindowSize</a> is implemented with will send window size events directly to the event callback that every window has and that GLFW implements for its windows. If you have set a <a class="el" href="window_guide.html#window_size">window size callback</a> GLFW will call it in turn with the new size before everything returns back out of the <a class="el" href="group__window.html#ga371911f12c74c504dd8d47d832d095cb">glfwSetWindowSize</a> call.</p>
+<h1><a class="anchor" id="input_keyboard"></a>
+Keyboard input</h1>
+<p>GLFW divides keyboard input into two categories; key events and character events. Key events relate to actual physical keyboard keys, whereas character events relate to the Unicode code points generated by pressing some of them.</p>
+<p>Keys and characters do not map 1:1. A single key press may produce several characters, and a single character may require several keys to produce. This may not be the case on your machine, but your users are likely not all using the same keyboard layout, input method or even operating system as you.</p>
+<h2><a class="anchor" id="input_key"></a>
+Key input</h2>
+<p>If you wish to be notified when a physical key is pressed or released or when it repeats, set a key callback.</p>

+<p>The value of an axis or button field can be a joystick button, a joystick axis, a hat bitmask or empty. Joystick buttons are specified as <code>bN</code>, for example <code>b2</code> for the third button. Joystick axes are specified as <code>aN</code>, for example <code>a7</code> for the eighth button. Joystick hat bit masks are specified as <code>hN.N</code>, for example <code>h0.8</code> for left on the first hat. More than one bit may be set in the mask.</p>
+<p>Before an axis there may be a <code>+</code> or <code>-</code> range modifier, for example <code>+a3</code> for the positive half of the fourth axis. This restricts input to only the positive or negative halves of the joystick axis. After an axis or half-axis there may be the <code>~</code> inversion modifier, for example <code>a2~</code> or <code>-a7~</code>. This negates the values of the gamepad axis.</p>
+<p>The hat bit mask match the <a class="el" href="group__hat__state.html">hat states</a> in the joystick functions.</p>
+<p>There is also the special <code>platform</code> field that specifies which platform the mapping is valid for. Possible values are <code>Windows</code>, <code>Mac OS X</code> and <code>Linux</code>.</p>
+<p>Below is an example of what a gamepad mapping might look like. It is the one built into GLFW for Xbox controllers accessed via the XInput API on Windows. This example has been broken into several lines to fit on the page, but real gamepad mappings must be a single line.</p>

+<div class="textblock"><p>There are several interfaces inside GLFW. Each interface has its own area of responsibility and its own naming conventions.</p>
+<h1><a class="anchor" id="internals_public"></a>
+Public interface</h1>
+<p>The most well-known is the public interface, described in the <a class="el" href="glfw3_8h.html" title="The header of the GLFW 3 API.">glfw3.h</a> header file. This is implemented in source files shared by all platforms and these files contain no platform-specific code. This code usually ends up calling the platform and internal interfaces to do the actual work.</p>
+<p>The public interface uses the OpenGL naming conventions except with GLFW and glfw instead of GL and gl. For struct members, where OpenGL sets no precedent, it use headless camel case.</p>
+<p>Examples: <code>glfwCreateWindow</code>, <code>GLFWwindow</code>, <code>GLFW_RED_BITS</code></p>
+<h1><a class="anchor" id="internals_native"></a>
+Native interface</h1>
+<p>The <a class="el" href="group__native.html">native interface</a> is a small set of publicly available but platform-specific functions, described in the <a class="el" href="glfw3native_8h.html" title="The header of the native access functions.">glfw3native.h</a> header file and used to gain access to the underlying window, context and (on some platforms) display handles used by the platform interface.</p>
+<p>The function names of the native interface are similar to those of the public interface, but embeds the name of the interface that the returned handle is from.</p>
+<p>Examples: <code>glfwGetX11Window</code>, <code>glfwGetWGLContext</code></p>
+<h1><a class="anchor" id="internals_internal"></a>
+Internal interface</h1>
+<p>The internal interface consists of utility functions used by all other interfaces. It is shared code implemented in the same shared source files as the public and event interfaces. The internal interface is described in the internal.h header file.</p>
+<p>The internal interface is in charge of GLFW's global data, which it stores in a <code>_GLFWlibrary</code> struct named <code>_glfw</code>.</p>
+<p>The internal interface uses the same style as the public interface, except all global names have a leading underscore.</p>
+<p>Examples: <code>_glfwIsValidContextConfig</code>, <code>_GLFWwindow</code>, <code>_glfw.monitorCount</code></p>
+<h1><a class="anchor" id="internals_platform"></a>
+Platform interface</h1>
+<p>The platform interface implements all platform-specific operations as a service to the public interface. This includes event processing. The platform interface is never directly called by application code and never directly calls application-provided callbacks. It is also prohibited from modifying the platform-independent part of the internal structs. Instead, it calls the event interface when events interesting to GLFW are received.</p>
+<p>The platform interface mirrors those parts of the public interface that needs to perform platform-specific operations on some or all platforms. The are also named the same except that the glfw function prefix is replaced by _glfwPlatform.</p>
+<p>Examples: <code>_glfwPlatformCreateWindow</code></p>
+<p>The platform interface also defines structs that contain platform-specific global and per-object state. Their names mirror those of the internal interface, except that an interface-specific suffix is added.</p>
+<p>Examples: <code>_GLFWwindowX11</code>, <code>_GLFWcontextWGL</code></p>
+<p>These structs are incorporated as members into the internal interface structs using special macros that name them after the specific interface used. This prevents shared code from accidentally using these members.</p>
+<p>Examples: <code>window-&gt;win32.handle</code>, <code>_glfw.x11.display</code></p>
+<h1><a class="anchor" id="internals_event"></a>
+Event interface</h1>
+<p>The event interface is implemented in the same shared source files as the public interface and is responsible for delivering the events it receives to the application, either via callbacks, via window state changes or both.</p>
+<p>The function names of the event interface use a <code>_glfwInput</code> prefix and the ObjectEvent pattern.</p>
+<p>Examples: <code>_glfwInputWindowFocus</code>, <code>_glfwInputCursorPos</code></p>
+<h1><a class="anchor" id="internals_static"></a>
+Static functions</h1>
+<p>Static functions may be used by any interface and have no prefixes or suffixes. These use headless camel case.</p>
+<p>Examples: <code>isValidElementForJoystick</code></p>
+<h1><a class="anchor" id="internals_config"></a>
+Configuration macros</h1>
+<p>GLFW uses a number of configuration macros to select at compile time which interfaces and code paths to use. They are defined in the glfw_config.h header file, which is generated from the <code>glfw_config.h.in</code> file by CMake.</p>
+<p>Configuration macros the same style as tokens in the public interface, except with a leading underscore.</p>
+<p>Examples: <code>_GLFW_WIN32</code>, <code>_GLFW_BUILD_DLL</code> </p>

+<h1><a class="anchor" id="intro_init"></a>
+Initialization and termination</h1>
+<p>Before most GLFW functions may be called, the library must be initialized. This initialization checks what features are available on the machine, enumerates monitors and joysticks, initializes the timer and performs any required platform-specific initialization.</p>
+<p>Only the following functions may be called before the library has been successfully initialized, and only from the main thread.</p>

The library only needs to be initialized once and additional calls to an already initialized library will return <code>GLFW_TRUE</code> immediately.</p>
+<p>Once the library has been successfully initialized, it should be terminated before the application exits.

+Terminating GLFW</h2>
+<p>Before your application exits, you should terminate the GLFW library if it has been initialized. This is done with <a class="el" href="group__init.html#gaaae48c0a18607ea4a4ba951d939f0901">glfwTerminate</a>.</p>
+<div class="fragment"><div class="line"><a class="code" href="group__init.html#gaaae48c0a18607ea4a4ba951d939f0901">glfwTerminate</a>();</div>
+</div><!-- fragment --><p>This will destroy any remaining window, monitor and cursor objects, restore any modified gamma ramps, re-enable the screensaver if it had been disabled and free any other resources allocated by GLFW.</p>
+<p>Once the library is terminated, it is as if it had never been initialized and you will need to initialize it again before being able to use GLFW. If the library was not initialized or had already been terminated, it return immediately.</p>
+<h1><a class="anchor" id="error_handling"></a>
+Error handling</h1>
+<p>Some GLFW functions have return values that indicate an error, but this is often not very helpful when trying to figure out what happened or why it occurred. Other functions have no return value reserved for errors, so error notification needs a separate channel. Finally, far from all GLFW functions have return values.</p>
+<p>The last <a class="el" href="group__errors.html">error code</a> for the calling thread can be queried at any time with <a class="el" href="group__init.html#ga944986b4ec0b928d488141f92982aa18">glfwGetError</a>.</p>
+<div class="fragment"><div class="line"><span class="keywordtype">int</span> code = <a class="code" href="group__init.html#ga944986b4ec0b928d488141f92982aa18">glfwGetError</a>(NULL);</div>

+<p>The error code indicates the general category of the error. Some error codes, such as <a class="el" href="group__errors.html#ga2374ee02c177f12e1fa76ff3ed15e14a">GLFW_NOT_INITIALIZED</a> has only a single meaning, whereas others like <a class="el" href="group__errors.html#gad44162d78100ea5e87cdd38426b8c7a1">GLFW_PLATFORM_ERROR</a> are used for many different errors.</p>
+<p>GLFW often has more information about an error than its general category. You can retrieve a UTF-8 encoded human-readable description along with the error code. If no error has occurred since the last call, the description is set to <code>NULL</code>.</p>

+<p><b>Reported errors are never fatal.</b> As long as GLFW was successfully initialized, it will remain initialized and in a safe state until terminated regardless of how many errors occur. If an error occurs during initialization that causes <a class="el" href="group__init.html#ga317aac130a235ab08c6db0834907d85e">glfwInit</a> to fail, any part of the library that was initialized will be safely terminated.</p>
+<p>Do not rely on a currently invalid call to generate a specific error, as in the future that same call may generate a different error or become valid.</p>
+<h1><a class="anchor" id="coordinate_systems"></a>
+Coordinate systems</h1>
+<p>GLFW has two primary coordinate systems: the <em>virtual screen</em> and the window <em>content area</em> or <em>content area</em>. Both use the same unit: <em>virtual screen coordinates</em>, or just <em>screen coordinates</em>, which don't necessarily correspond to pixels.</p>
+<p><img src="spaces.svg" alt="" width="90%" class="inline"/></p>
+<p>Both the virtual screen and the content area coordinate systems have the X-axis pointing to the right and the Y-axis pointing down.</p>
+<p>Window and monitor positions are specified as the position of the upper-left corners of their content areas relative to the virtual screen, while cursor positions are specified relative to a window's content area.</p>
+<p>Because the origin of the window's content area coordinate system is also the point from which the window position is specified, you can translate content area coordinates to the virtual screen by adding the window position. The window frame, when present, extends out from the content area but does not affect the window position.</p>
+<p>Almost all positions and sizes in GLFW are measured in screen coordinates relative to one of the two origins above. This includes cursor positions, window positions and sizes, window frame sizes, monitor positions and video mode resolutions.</p>
+<p>Two exceptions are the <a class="el" href="monitor_guide.html#monitor_size">monitor physical size</a>, which is measured in millimetres, and <a class="el" href="window_guide.html#window_fbsize">framebuffer size</a>, which is measured in pixels.</p>
+<p>Pixels and screen coordinates may map 1:1 on your machine, but they won't on every other machine, for example on a Mac with a Retina display. The ratio between screen coordinates and pixels may also change at run-time depending on which monitor the window is currently considered to be on.</p>
+<h1><a class="anchor" id="guarantees_limitations"></a>
+Guarantees and limitations</h1>
+<p>This section describes the conditions under which GLFW can be expected to function, barring bugs in the operating system or drivers. Use of GLFW outside of these limits may work on some platforms, or on some machines, or some of the time, or on some versions of GLFW, but it may break at any time and this will not be considered a bug.</p>
+<h2><a class="anchor" id="lifetime"></a>
+Pointer lifetimes</h2>
+<p>GLFW will never free any pointer you provide to it and you must never free any pointer it provides to you.</p>
+<p>Many GLFW functions return pointers to dynamically allocated structures, strings or arrays, and some callbacks are provided with strings or arrays. These are always managed by GLFW and should never be freed by the application. The lifetime of these pointers is documented for each GLFW function and callback. If you need to keep this data, you must copy it before its lifetime expires.</p>
+<p>Many GLFW functions accept pointers to structures or strings allocated by the application. These are never freed by GLFW and are always the responsibility of the application. If GLFW needs to keep the data in these structures or strings, it is copied before the function returns.</p>
+<p>Pointer lifetimes are guaranteed not to be shortened in future minor or patch releases.</p>
+<h2><a class="anchor" id="reentrancy"></a>
+Reentrancy</h2>
+<p>GLFW event processing and object destruction are not reentrant. This means that the following functions must not be called from any callback function:</p>
+<ul>
+<li><a class="el" href="group__window.html#gacdf43e51376051d2c091662e9fe3d7b2">glfwDestroyWindow</a></li>
+<li><a class="el" href="group__input.html#ga81b952cd1764274d0db7fb3c5a79ba6a">glfwDestroyCursor</a></li>

+<li><a class="el" href="group__init.html#gaaae48c0a18607ea4a4ba951d939f0901">glfwTerminate</a></li>
+</ul>
+<p>These functions may be made reentrant in future minor or patch releases, but functions not on this list will not be made non-reentrant.</p>
+<h2><a class="anchor" id="thread_safety"></a>
+Thread safety</h2>
+<p>Most GLFW functions must only be called from the main thread (the thread that calls main), but some may be called from any thread once the library has been initialized. Before initialization the whole library is thread-unsafe.</p>
+<p>The reference documentation for every GLFW function states whether it is limited to the main thread.</p>
+<p>Initialization, termination, event processing and the creation and destruction of windows, cursors and OpenGL and OpenGL ES contexts are all restricted to the main thread due to limitations of one or several platforms.</p>
+<p>Because event processing must be performed on the main thread, all callbacks except for the error callback will only be called on that thread. The error callback may be called on any thread, as any GLFW function may generate errors.</p>
+<p>The error code and description may be queried from any thread.</p>
+<ul>
+<li><a class="el" href="group__init.html#ga944986b4ec0b928d488141f92982aa18">glfwGetError</a></li>

+<p>GLFW uses synchronization objects internally only to manage the per-thread context and error states. Additional synchronization is left to the application.</p>
+<p>Functions that may currently be called from any thread will always remain so, but functions that are currently limited to the main thread may be updated to allow calls from any thread in future releases.</p>
+<h2><a class="anchor" id="compatibility"></a>
+Version compatibility</h2>
+<p>GLFW uses <a href="https://semver.org/">Semantic Versioning</a>. This guarantees source and binary backward compatibility with earlier minor versions of the API. This means that you can drop in a newer version of the library and existing programs will continue to compile and existing binaries will continue to run.</p>
+<p>Once a function or constant has been added, the signature of that function or value of that constant will remain unchanged until the next major version of GLFW. No compatibility of any kind is guaranteed between major versions.</p>
+<p>Undocumented behavior, i.e. behavior that is not described in the documentation, may change at any time until it is documented.</p>
+<p>If the reference documentation and the implementation differ, the reference documentation will almost always take precedence and the implementation will be fixed in the next release. The reference documentation will also take precedence over anything stated in a guide.</p>
+<h2><a class="anchor" id="event_order"></a>
+Event order</h2>
+<p>The order of arrival of related events is not guaranteed to be consistent across platforms. The exception is synthetic key and mouse button release events, which are always delivered after the window defocus event.</p>
+<h1><a class="anchor" id="intro_version"></a>
+Version management</h1>
+<p>GLFW provides mechanisms for identifying what version of GLFW your application was compiled against as well as what version it is currently running against. If you are loading GLFW dynamically (not just linking dynamically), you can use this to verify that the library binary is compatible with your application.</p>
+<h2><a class="anchor" id="intro_version_compile"></a>
+Compile-time version</h2>
+<p>The compile-time version of GLFW is provided by the GLFW header with the <code>GLFW_VERSION_MAJOR</code>, <code>GLFW_VERSION_MINOR</code> and <code>GLFW_VERSION_REVISION</code> macros.</p>
+<div class="fragment"><div class="line">printf(<span class="stringliteral">&quot;Compiled against GLFW %i.%i.%i\n&quot;</span>,</div>
+<div class="line">       <a class="code" href="group__init.html#ga6337d9ea43b22fc529b2bba066b4a576">GLFW_VERSION_MAJOR</a>,</div>

+Run-time version</h2>
+<p>The run-time version can be retrieved with <a class="el" href="group__init.html#ga9f8ffaacf3c269cc48eafbf8b9b71197">glfwGetVersion</a>, a function that may be called regardless of whether GLFW is initialized.</p>
+<div class="fragment"><div class="line"><span class="keywordtype">int</span> major, minor, revision;</div>
+<div class="line"><a class="code" href="group__init.html#ga9f8ffaacf3c269cc48eafbf8b9b71197">glfwGetVersion</a>(&amp;major, &amp;minor, &amp;revision);</div>

+</div><!-- fragment --><h2><a class="anchor" id="intro_version_string"></a>
+Version string</h2>
+<p>GLFW 3 also provides a compile-time generated version string that describes the version, platform, compiler and any platform-specific compile-time options. This is primarily intended for submitting bug reports, to allow developers to see which code paths are enabled in a binary.</p>
+<p>The version string is returned by <a class="el" href="group__init.html#ga23d47dc013fce2bf58036da66079a657">glfwGetVersionString</a>, a function that may be called regardless of whether GLFW is initialized.</p>
+<p><b>Do not use the version string</b> to parse the GLFW library version. The <a class="el" href="group__init.html#ga9f8ffaacf3c269cc48eafbf8b9b71197">glfwGetVersion</a> function already provides the version of the running library binary.</p>
+<p>The format of the string is as follows:</p><ul>
+<li>The version of GLFW</li>
+<li>The name of the window system API</li>
+<li>The name of the context creation API</li>
+<li>Any additional options or APIs</li>
+</ul>
+<p>For example, when compiling GLFW 3.0 with MinGW using the Win32 and WGL back ends, the version string may look something like this:</p>
+<div class="fragment"><div class="line">3.0.0 Win32 WGL MinGW</div>

+Monitor objects</h1>
+<p>A monitor object represents a currently connected monitor and is represented as a pointer to the <a href="https://en.wikipedia.org/wiki/Opaque_data_type">opaque</a> type <a class="el" href="group__monitor.html#ga8d9efd1cde9426692c73fe40437d0ae3">GLFWmonitor</a>. Monitor objects cannot be created or destroyed by the application and retain their addresses until the monitors they represent are disconnected or until the library is <a class="el" href="intro_guide.html#intro_init_terminate">terminated</a>.</p>
+<p>Each monitor has a current video mode, a list of supported video modes, a virtual position, a human-readable name, an estimated physical size and a gamma ramp. One of the monitors is the primary monitor.</p>
+<p>The virtual position of a monitor is in <a class="el" href="intro_guide.html#coordinate_systems">screen coordinates</a> and, together with the current video mode, describes the viewports that the connected monitors provide into the virtual desktop that spans them.</p>
+<p>To see how GLFW views your monitor setup and its available video modes, run the <code>monitors</code> test program.</p>
+<h2><a class="anchor" id="monitor_monitors"></a>
+Retrieving monitors</h2>
+<p>The primary monitor is returned by <a class="el" href="group__monitor.html#ga721867d84c6d18d6790d64d2847ca0b1">glfwGetPrimaryMonitor</a>. It is the user's preferred monitor and is usually the one with global UI elements like task bar or menu bar.</p>
+<div class="fragment"><div class="line"><a class="code" href="group__monitor.html#ga8d9efd1cde9426692c73fe40437d0ae3">GLFWmonitor</a>* primary = <a class="code" href="group__monitor.html#ga721867d84c6d18d6790d64d2847ca0b1">glfwGetPrimaryMonitor</a>();</div>

+</div><!-- fragment --><p>The primary monitor is always the first monitor in the returned array, but other monitors may be moved to a different index when a monitor is connected or disconnected.</p>
+<h2><a class="anchor" id="monitor_event"></a>
+Monitor configuration changes</h2>
+<p>If you wish to be notified when a monitor is connected or disconnected, set a monitor callback.</p>

+Video modes</h2>
+<p>GLFW generally does a good job selecting a suitable video mode when you create a full screen window, change its video mode or make a windowed one full screen, but it is sometimes useful to know exactly which video modes are supported.</p>
+<p>Video modes are represented as <a class="el" href="structGLFWvidmode.html">GLFWvidmode</a> structures. You can get an array of the video modes supported by a monitor with <a class="el" href="group__monitor.html#ga820b0ce9a5237d645ea7cbb4bd383458">glfwGetVideoModes</a>.

+</div><!-- fragment --><p>The content scale is the ratio between the current DPI and the platform's default DPI. This is especially important for text and any UI elements. If the pixel dimensions of your UI scaled by this look appropriate on your machine then it should appear at a reasonable size on other machines regardless of their DPI and scaling settings. This relies on the system DPI and scaling settings being somewhat correct.</p>
+<p>The content scale may depend on both the monitor resolution and pixel density and on user settings. It may be very different from the raw DPI calculated from the physical size and current resolution.</p>

+<div class="textblock"><p>This is a transition guide for moving from GLFW 2 to 3. It describes what has changed or been removed, but does <em>not</em> include <a class="el" href="news.html">new features</a> unless they are required when moving an existing code base onto the new API. For example, the new multi-monitor functions are required to create full screen windows with GLFW 3.</p>
+<h1><a class="anchor" id="moving_removed"></a>
+Changed and removed features</h1>
+<h2><a class="anchor" id="moving_renamed_files"></a>
+Renamed library and header file</h2>
+<p>The GLFW 3 header is named <a class="el" href="glfw3_8h.html">glfw3.h</a> and moved to the <code>GLFW</code> directory, to avoid collisions with the headers of other major versions. Similarly, the GLFW 3 library is named <code>glfw3,</code> except when it's installed as a shared library on Unix-like systems, where it uses the <a href="https://en.wikipedia.org/wiki/soname">soname</a> <code>libglfw.so.3</code>.</p>
+<dl class="section user"><dt>Old syntax</dt><dd><div class="fragment"><div class="line"><span class="preprocessor">#include &lt;GL/glfw.h&gt;</span></div>

+<h2><a class="anchor" id="moving_threads"></a>
+Removal of threading functions</h2>
+<p>The threading functions have been removed, including the per-thread sleep function. They were fairly primitive, under-used, poorly integrated and took time away from the focus of GLFW (i.e. context, input and window). There are better threading libraries available and native threading support is available in both <a href="https://en.cppreference.com/w/cpp/thread">C++11</a> and <a href="https://en.cppreference.com/w/c/thread">C11</a>, both of which are gaining traction.</p>
+<p>If you wish to use the C++11 or C11 facilities but your compiler doesn't yet support them, see the <a href="https://gitorious.org/tinythread/tinythreadpp">TinyThread++</a> and <a href="https://github.com/tinycthread/tinycthread">TinyCThread</a> projects created by the original author of GLFW. These libraries implement a usable subset of the threading APIs in C++11 and C11, and in fact some GLFW 3 test programs use TinyCThread.</p>
+<p>However, GLFW 3 has better support for <em>use from multiple threads</em> than GLFW 2 had. Contexts can be made current on any thread, although only a single thread at a time, and the documentation explicitly states which functions may be used from any thread and which must only be used from the main thread.</p>
+<dl class="section user"><dt>Removed functions</dt><dd><code>glfwSleep</code>, <code>glfwCreateThread</code>, <code>glfwDestroyThread</code>, <code>glfwWaitThread</code>, <code>glfwGetThreadID</code>, <code>glfwCreateMutex</code>, <code>glfwDestroyMutex</code>, <code>glfwLockMutex</code>, <code>glfwUnlockMutex</code>, <code>glfwCreateCond</code>, <code>glfwDestroyCond</code>, <code>glfwWaitCond</code>, <code>glfwSignalCond</code>, <code>glfwBroadcastCond</code> and <code>glfwGetNumberOfProcessors</code>.</dd></dl>
+<dl class="section user"><dt>Removed types</dt><dd><code>GLFWthreadfun</code></dd></dl>
+<h2><a class="anchor" id="moving_image"></a>
+Removal of image and texture loading</h2>
+<p>The image and texture loading functions have been removed. They only supported the Targa image format, making them mostly useful for beginner level examples. To become of sufficiently high quality to warrant keeping them in GLFW 3, they would need not only to support other formats, but also modern extensions to OpenGL texturing. This would either add a number of external dependencies (libjpeg, libpng, etc.), or force GLFW to ship with inline versions of these libraries.</p>
+<p>As there already are libraries doing this, it is unnecessary both to duplicate the work and to tie the duplicate to GLFW. The resulting library would also be platform-independent, as both OpenGL and stdio are available wherever GLFW is.</p>
+<dl class="section user"><dt>Removed functions</dt><dd><code>glfwReadImage</code>, <code>glfwReadMemoryImage</code>, <code>glfwFreeImage</code>, <code>glfwLoadTexture2D</code>, <code>glfwLoadMemoryTexture2D</code> and <code>glfwLoadTextureImage2D</code>.</dd></dl>
+<h2><a class="anchor" id="moving_stdcall"></a>
+Removal of GLFWCALL macro</h2>
+<p>The <code>GLFWCALL</code> macro, which made callback functions use <a href="https://msdn.microsoft.com/en-us/library/zxk0tw93.aspx">__stdcall</a> on Windows, has been removed. GLFW is written in C, not Pascal. Removing this macro means there's one less thing for application programmers to remember, i.e. the requirement to mark all callback functions with <code>GLFWCALL</code>. It also simplifies the creation of DLLs and DLL link libraries, as there's no need to explicitly disable <code>@n</code> entry point suffixes.</p>

+<h2><a class="anchor" id="moving_window_handles"></a>
+Window handle parameters</h2>
+<p>Because GLFW 3 supports multiple windows, window handle parameters have been added to all window-related GLFW functions and callbacks. The handle of a newly created window is returned by <a class="el" href="group__window.html#ga5c336fddf2cbb5b92f65f10fb6043344">glfwCreateWindow</a> (formerly <code>glfwOpenWindow</code>). Window handles are pointers to the <a href="https://en.wikipedia.org/wiki/Opaque_data_type">opaque</a> type <a class="el" href="group__window.html#ga3c96d80d363e67d13a41b5d1821f3242">GLFWwindow</a>.</p>

+</div><!-- fragment --></dd></dl>
+<h2><a class="anchor" id="moving_monitor"></a>
+Explicit monitor selection</h2>
+<p>GLFW 3 provides support for multiple monitors. To request a full screen mode window, instead of passing <code>GLFW_FULLSCREEN</code> you specify which monitor you wish the window to use. The <a class="el" href="group__monitor.html#ga721867d84c6d18d6790d64d2847ca0b1">glfwGetPrimaryMonitor</a> function returns the monitor that GLFW 2 would have selected, but there are many other <a class="el" href="monitor_guide.html">monitor functions</a>. Monitor handles are pointers to the <a href="https://en.wikipedia.org/wiki/Opaque_data_type">opaque</a> type <a class="el" href="group__monitor.html#ga8d9efd1cde9426692c73fe40437d0ae3">GLFWmonitor</a>.</p>

+<h2><a class="anchor" id="moving_autopoll"></a>
+Removal of automatic event polling</h2>
+<p>GLFW 3 does not automatically poll for events in <a class="el" href="group__window.html#ga15a5a1ee5b3c2ca6b15ca209a12efd14">glfwSwapBuffers</a>, meaning you need to call <a class="el" href="group__window.html#ga37bd57223967b4211d60ca1a0bf3c832">glfwPollEvents</a> or <a class="el" href="group__window.html#ga554e37d781f0a997656c26b2c56c835e">glfwWaitEvents</a> yourself. Unlike buffer swap, which acts on a single window, the event processing functions act on all windows at once.</p>

+<h2><a class="anchor" id="moving_context"></a>
+Explicit context management</h2>
+<p>Each GLFW 3 window has its own OpenGL context and only you, the application programmer, can know which context should be current on which thread at any given time. Therefore, GLFW 3 leaves that decision to you.</p>
+<p>This means that you need to call <a class="el" href="group__context.html#ga1c04dc242268f827290fe40aa1c91157">glfwMakeContextCurrent</a> after creating a window before you can call any OpenGL functions.</p>
+<h2><a class="anchor" id="moving_hidpi"></a>
+Separation of window and framebuffer sizes</h2>
+<p>Window positions and sizes now use screen coordinates, which may not be the same as pixels on machines with high-DPI monitors. This is important as OpenGL uses pixels, not screen coordinates. For example, the rectangle specified with <code>glViewport</code> needs to use pixels. Therefore, framebuffer size functions have been added. You can retrieve the size of the framebuffer of a window with <a class="el" href="group__window.html#ga0e2637a4161afb283f5300c7f94785c9">glfwGetFramebufferSize</a> function. A framebuffer size callback has also been added, which can be set with <a class="el" href="group__window.html#gab3fb7c3366577daef18c0023e2a8591f">glfwSetFramebufferSizeCallback</a>.</p>

+<h2><a class="anchor" id="moving_window_close"></a>
+Window closing changes</h2>
+<p>The <code>GLFW_OPENED</code> window parameter has been removed. As long as the window has not been destroyed, whether through <a class="el" href="group__window.html#gacdf43e51376051d2c091662e9fe3d7b2">glfwDestroyWindow</a> or <a class="el" href="group__init.html#gaaae48c0a18607ea4a4ba951d939f0901">glfwTerminate</a>, the window is "open".</p>
+<p>A user attempting to close a window is now just an event like any other. Unlike GLFW 2, windows and contexts created with GLFW 3 will never be destroyed unless you choose them to be. Each window now has a close flag that is set to <code>GLFW_TRUE</code> when the user attempts to close that window. By default, nothing else happens and the window stays visible. It is then up to you to either destroy the window, take some other action or ignore the request.</p>
+<p>You can query the close flag at any time with <a class="el" href="group__window.html#ga24e02fbfefbb81fc45320989f8140ab5">glfwWindowShouldClose</a> and set it at any time with <a class="el" href="group__window.html#ga49c449dde2a6f87d996f4daaa09d6708">glfwSetWindowShouldClose</a>.</p>

+<h2><a class="anchor" id="moving_hints"></a>
+Persistent window hints</h2>
+<p>The <code>glfwOpenWindowHint</code> function has been renamed to <a class="el" href="group__window.html#ga7d9c8c62384b1e2821c4dc48952d2033">glfwWindowHint</a>.</p>
+<p>Window hints are no longer reset to their default values on window creation, but instead retain their values until modified by <a class="el" href="group__window.html#ga7d9c8c62384b1e2821c4dc48952d2033">glfwWindowHint</a> or <a class="el" href="group__window.html#gaa77c4898dfb83344a6b4f76aa16b9a4a">glfwDefaultWindowHints</a>, or until the library is terminated and re-initialized.</p>
+<h2><a class="anchor" id="moving_video_modes"></a>
+Video mode enumeration</h2>
+<p>Video mode enumeration is now per-monitor. The <a class="el" href="group__monitor.html#ga820b0ce9a5237d645ea7cbb4bd383458">glfwGetVideoModes</a> function now returns all available modes for a specific monitor instead of requiring you to guess how large an array you need. The <code>glfwGetDesktopMode</code> function, which had poorly defined behavior, has been replaced by <a class="el" href="group__monitor.html#gafc1bb972a921ad5b3bd5d63a95fc2d52">glfwGetVideoMode</a>, which returns the current mode of a monitor.</p>
+<h2><a class="anchor" id="moving_char_up"></a>
+Removal of character actions</h2>
+<p>The action parameter of the <a class="el" href="group__input.html#gabf24451c7ceb1952bc02b17a0d5c3e5f">character callback</a> has been removed. This was an artefact of the origin of GLFW, i.e. being developed in English by a Swede. However, many keyboard layouts require more than one key to produce characters with diacritical marks. Even the Swedish keyboard layout requires this for uncommon cases like ü.</p>

+<h2><a class="anchor" id="moving_cursorpos"></a>
+Cursor position changes</h2>
+<p>The <code>glfwGetMousePos</code> function has been renamed to <a class="el" href="group__input.html#ga01d37b6c40133676b9cea60ca1d7c0cc">glfwGetCursorPos</a>, <code>glfwSetMousePos</code> to <a class="el" href="group__input.html#ga04b03af936d906ca123c8f4ee08b39e7">glfwSetCursorPos</a> and <code>glfwSetMousePosCallback</code> to <a class="el" href="group__input.html#gac1f879ab7435d54d4d79bb469fe225d7">glfwSetCursorPosCallback</a>.</p>
+<p>The cursor position is now <code>double</code> instead of <code>int</code>, both for the direct functions and for the callback. Some platforms can provide sub-pixel cursor movement and this data is now passed on to the application where available. On platforms where this is not provided, the decimal part is zero.</p>
+<p>GLFW 3 only allows you to position the cursor within a window using <a class="el" href="group__input.html#ga04b03af936d906ca123c8f4ee08b39e7">glfwSetCursorPos</a> (formerly <code>glfwSetMousePos</code>) when that window is active. Unless the window is active, the function fails silently.</p>
+<h2><a class="anchor" id="moving_wheel"></a>
+Wheel position replaced by scroll offsets</h2>
+<p>The <code>glfwGetMouseWheel</code> function has been removed. Scrolling is the input of offsets and has no absolute position. The mouse wheel callback has been replaced by a <a class="el" href="group__input.html#ga4687e2199c60a18a8dd1da532e6d75c9">scroll callback</a> that receives two-dimensional floating point scroll offsets. This allows you to receive precise scroll data from for example modern touchpads.</p>

+<h2><a class="anchor" id="moving_repeat"></a>
+Key repeat action</h2>
+<p>The <code>GLFW_KEY_REPEAT</code> enable has been removed and key repeat is always enabled for both keys and characters. A new key action, <code>GLFW_REPEAT</code>, has been added to allow the <a class="el" href="group__input.html#ga0192a232a41e4e82948217c8ba94fdfd">key callback</a> to distinguish an initial key press from a repeat. Note that <a class="el" href="group__input.html#gadd341da06bc8d418b4dc3a3518af9ad2">glfwGetKey</a> still returns only <code>GLFW_PRESS</code> or <code>GLFW_RELEASE</code>.</p>
+<h2><a class="anchor" id="moving_keys"></a>
+Physical key input</h2>
+<p>GLFW 3 key tokens map to physical keys, unlike in GLFW 2 where they mapped to the values generated by the current keyboard layout. The tokens are named according to the values they would have using the standard US layout, but this is only a convenience, as most programmers are assumed to know that layout. This means that (for example) <code>GLFW_KEY_LEFT_BRACKET</code> is always a single key and is the same key in the same place regardless of what keyboard layouts the users of your program has.</p>
+<p>The key input facility was never meant for text input, although using it that way worked slightly better in GLFW 2. If you were using it to input text, you should be using the character callback instead, on both GLFW 2 and 3. This will give you the characters being input, as opposed to the keys being pressed.</p>
+<p>GLFW 3 has key tokens for all keys on a standard 105 key keyboard, so instead of having to remember whether to check for &lsquo;'a&rsquo;<code>or</code>'A'<code>, you now check for </code>GLFW_KEY_A`.</p>
+<h2><a class="anchor" id="moving_joystick"></a>
+Joystick function changes</h2>
+<p>The <code>glfwGetJoystickPos</code> function has been renamed to <a class="el" href="group__input.html#gaa8806536731e92c061bc70bcff6edbd0">glfwGetJoystickAxes</a>.</p>
+<p>The <code>glfwGetJoystickParam</code> function and the <code>GLFW_PRESENT</code>, <code>GLFW_AXES</code> and <code>GLFW_BUTTONS</code> tokens have been replaced by the <a class="el" href="group__input.html#gaed0966cee139d815317f9ffcba64c9f1">glfwJoystickPresent</a> function as well as axis and button counts returned by the <a class="el" href="group__input.html#gaa8806536731e92c061bc70bcff6edbd0">glfwGetJoystickAxes</a> and <a class="el" href="group__input.html#gadb3cbf44af90a1536f519659a53bddd6">glfwGetJoystickButtons</a> functions.</p>
+<h2><a class="anchor" id="moving_mbcs"></a>
+Win32 MBCS support</h2>
+<p>The Win32 port of GLFW 3 will not compile in <a href="https://msdn.microsoft.com/en-us/library/5z097dxa.aspx">MBCS mode</a>. However, because the use of the Unicode version of the Win32 API doesn't affect the process as a whole, but only those windows created using it, it's perfectly possible to call MBCS functions from other parts of the same application. Therefore, even if an application using GLFW has MBCS mode code, there's no need for GLFW itself to support it.</p>
+<h2><a class="anchor" id="moving_windows"></a>
+Support for versions of Windows older than XP</h2>
+<p>All explicit support for version of Windows older than XP has been removed. There is no code that actively prevents GLFW 3 from running on these earlier versions, but it uses Win32 functions that those versions lack.</p>
+<p>Windows XP was released in 2001, and by now (January 2015) it has not only replaced almost all earlier versions of Windows, but is itself rapidly being replaced by Windows 7 and 8. The MSDN library doesn't even provide documentation for version older than Windows 2000, making it difficult to maintain compatibility with these versions even if it was deemed worth the effort.</p>
+<p>The Win32 API has also not stood still, and GLFW 3 uses many functions only present on Windows XP or later. Even supporting an OS as new as XP (new from the perspective of GLFW 2, which still supports Windows 95) requires runtime checking for a number of functions that are present only on modern version of Windows.</p>
+<h2><a class="anchor" id="moving_syskeys"></a>
+Capture of system-wide hotkeys</h2>
+<p>The ability to disable and capture system-wide hotkeys like Alt+Tab has been removed. Modern applications, whether they're games, scientific visualisations or something else, are nowadays expected to be good desktop citizens and allow these hotkeys to function even when running in full screen mode.</p>
+<h2><a class="anchor" id="moving_terminate"></a>
+Automatic termination</h2>
+<p>GLFW 3 does not register <a class="el" href="group__init.html#gaaae48c0a18607ea4a4ba951d939f0901">glfwTerminate</a> with <code>atexit</code> at initialization, because <code>exit</code> calls registered functions from the calling thread and while it is permitted to call <code>exit</code> from any thread, <a class="el" href="group__init.html#gaaae48c0a18607ea4a4ba951d939f0901">glfwTerminate</a> must only be called from the main thread.</p>
+<p>To release all resources allocated by GLFW, you should call <a class="el" href="group__init.html#gaaae48c0a18607ea4a4ba951d939f0901">glfwTerminate</a> yourself, from the main thread, before the program terminates. Note that this destroys all windows not already destroyed with <a class="el" href="group__window.html#gacdf43e51376051d2c091662e9fe3d7b2">glfwDestroyWindow</a>, invalidating any window handles you may still have.</p>
+<h2><a class="anchor" id="moving_glu"></a>
+GLU header inclusion</h2>
+<p>GLFW 3 does not by default include the GLU header and GLU itself has been deprecated by <a href="https://en.wikipedia.org/wiki/Khronos_Group">Khronos</a>. <b>New projects should not use GLU</b>, but if you need it for legacy code that has been moved to GLFW 3, you can request that the GLFW header includes it by defining <a class="el" href="build_guide.html#GLFW_INCLUDE_GLU">GLFW_INCLUDE_GLU</a> before the inclusion of the GLFW header.</p>

+<p>There are many libraries that offer replacements for the functionality offered by GLU. For the matrix helper functions, see math libraries like <a href="https://github.com/g-truc/glm">GLM</a> (for C++), <a href="https://github.com/datenwolf/linmath.h">linmath.h</a> (for C) and others.

+Release notes for version 3.3</h1>
+<p>These are the release notes for version 3.3. For a more detailed view including all fixed bugs see the <a href="https://www.glfw.org/changelog.html">version history</a>.</p>
+<p>Please review the caveats, deprecations and removals if your project was written against an earlier version of GLFW 3.</p>
+<h2><a class="anchor" id="features_33"></a>
+New features in version 3.3</h2>
+<h3><a class="anchor" id="gamepad_33"></a>
+Gamepad input via SDL_GameControllerDB</h3>
+<p>GLFW can now remap game controllers to a standard Xbox-like layout using a built-in copy of SDL_GameControllerDB. Call <a class="el" href="group__input.html#gad0f676860f329d80f7e47e9f06a96f00">glfwJoystickIsGamepad</a> to check if a joystick has a mapping, <a class="el" href="group__input.html#gadccddea8bce6113fa459de379ddaf051">glfwGetGamepadState</a> to retrieve its input state, <a class="el" href="group__input.html#gaed5104612f2fa8e66aa6e846652ad00f">glfwUpdateGamepadMappings</a> to add newer mappings and <a class="el" href="group__input.html#ga5c71e3533b2d384db9317fcd7661b210">glfwGetGamepadName</a> and <a class="el" href="group__input.html#gae168c2c0b8cf2a1cb67c6b3c00bdd543">glfwGetJoystickGUID</a> for mapping related information.</p>
+<p>For more information see <a class="el" href="input_guide.html#gamepad">Gamepad input</a>.</p>
+<h3><a class="anchor" id="moltenvk_33"></a>
+Support for Vulkan on macOS via MoltenVK</h3>
+<p>GLFW now supports <a href="https://moltengl.com/moltenvk/">MoltenVK</a>, a Vulkan implementation on top of the Metal API, and its <code>VK_MVK_macos_surface</code> window surface creation extension. MoltenVK is included in the <a href="https://vulkan.lunarg.com/">macOS Vulkan SDK</a>.</p>
+<p>For more information see <a class="el" href="vulkan_guide.html">Vulkan guide</a>.</p>
+<h3><a class="anchor" id="content_scale_33"></a>
+Content scale queries for DPI-aware rendering</h3>
+<p>GLFW now provides content scales for windows and monitors, i.e. the ratio between their current DPI and the platform's default DPI, with <a class="el" href="group__window.html#gaf5d31de9c19c4f994facea64d2b3106c">glfwGetWindowContentScale</a> and <a class="el" href="group__monitor.html#gad3152e84465fa620b601265ebfcdb21b">glfwGetMonitorContentScale</a>.</p>
+<p>Changes of the content scale of a window can be received with the window content scale callback, set with <a class="el" href="group__window.html#gaf2832ebb5aa6c252a2d261de002c92d6">glfwSetWindowContentScaleCallback</a>.</p>
+<p>The <a class="el" href="window_guide.html#GLFW_SCALE_TO_MONITOR">GLFW_SCALE_TO_MONITOR</a> window hint enables automatic resizing of a window by the content scale of the monitor it is placed, on platforms like Windows where this is necessary. This takes effect both on creation and when the window is moved between monitors. It is related to but different from <a class="el" href="window_guide.html#GLFW_COCOA_RETINA_FRAMEBUFFER_hint">GLFW_COCOA_RETINA_FRAMEBUFFER</a>.</p>
+<p>For more information see <a class="el" href="window_guide.html#window_scale">Window content scale</a>.</p>
+<h3><a class="anchor" id="setwindowattrib_33"></a>
+Support for updating window attributes</h3>
+<p>GLFW now supports changing the <a class="el" href="window_guide.html#GLFW_DECORATED_attrib">GLFW_DECORATED</a>, <a class="el" href="window_guide.html#GLFW_RESIZABLE_attrib">GLFW_RESIZABLE</a>, <a class="el" href="window_guide.html#GLFW_FLOATING_attrib">GLFW_FLOATING</a>, <a class="el" href="window_guide.html#GLFW_AUTO_ICONIFY_attrib">GLFW_AUTO_ICONIFY</a> and <a class="el" href="window_guide.html#GLFW_FOCUS_ON_SHOW_attrib">GLFW_FOCUS_ON_SHOW</a> attributes for existing windows with <a class="el" href="group__window.html#gace2afda29b4116ec012e410a6819033e">glfwSetWindowAttrib</a>.</p>
+<p>For more information see <a class="el" href="window_guide.html#window_attribs">Window attributes</a>.</p>
+<h3><a class="anchor" id="raw_motion_33"></a>
+Support for raw mouse motion</h3>
+<p>GLFW now supports raw (unscaled and unaccelerated) mouse motion in disabled cursor mode with the <a class="el" href="input_guide.html#GLFW_RAW_MOUSE_MOTION">GLFW_RAW_MOUSE_MOTION</a> input mode. Raw mouse motion input is not yet implemented on macOS. Call <a class="el" href="group__input.html#gae4ee0dbd0d256183e1ea4026d897e1c2">glfwRawMouseMotionSupported</a> to check if GLFW can provide raw mouse motion on the current system.</p>
+<p>For more information see <a class="el" href="input_guide.html#raw_mouse_motion">Raw mouse motion</a>.</p>
+<h3><a class="anchor" id="joysticks_33"></a>
+Joystick hats</h3>
+<p>GLFW can now return the state of hats (i.e. POVs or D-pads) of a joystick with <a class="el" href="group__input.html#ga2d8d0634bb81c180899aeb07477a67ea">glfwGetJoystickHats</a>. For compatibility, hats are also exposed as buttons. This can be disabled with the <a class="el" href="intro_guide.html#GLFW_JOYSTICK_HAT_BUTTONS">GLFW_JOYSTICK_HAT_BUTTONS</a> initialization hint.</p>
+<p>For more information see <a class="el" href="input_guide.html#joystick_hat">Joystick hat states</a>.</p>
+<h3><a class="anchor" id="geterror_33"></a>
+Error query</h3>
+<p>GLFW now supports querying the last error code for the calling thread and its human-readable description with <a class="el" href="group__init.html#ga944986b4ec0b928d488141f92982aa18">glfwGetError</a>. This can be used instead of or together with the error callback.</p>
+<p>For more information see <a class="el" href="intro_guide.html#error_handling">Error handling</a>.</p>
+<h3><a class="anchor" id="init_hints_33"></a>
+Support for initialization hints</h3>
+<p>GLFW now supports setting library initialization hints with <a class="el" href="group__init.html#ga110fd1d3f0412822b4f1908c026f724a">glfwInitHint</a>. These must be set before initialization to take effect. Some of these hints are platform specific but are safe to set on any platform.</p>
+<p>For more information see <a class="el" href="intro_guide.html#init_hints">Initialization hints</a>.</p>
+<h3><a class="anchor" id="attention_33"></a>
+User attention request</h3>
+<p>GLFW now supports requesting user attention with <a class="el" href="group__window.html#ga2f8d59323fc4692c1d54ba08c863a703">glfwRequestWindowAttention</a>. Where possible this calls attention to the specified window. On platforms like macOS it calls attention to the whole application.</p>
+<p>For more information see <a class="el" href="window_guide.html#window_attention">Window attention request</a>.</p>
+<h3><a class="anchor" id="maximize_33"></a>
+Window maximization callback</h3>
+<p>GLFW now supports notifying the application that the window has been maximized <a class="el" href="group__window.html#gacbe64c339fbd94885e62145563b6dc93">glfwSetWindowMaximizeCallback</a>. This is called both when the window was maximized by the user and when it was done with <a class="el" href="group__window.html#ga3f541387449d911274324ae7f17ec56b">glfwMaximizeWindow</a>.</p>
+<p>For more information see <a class="el" href="window_guide.html#window_maximize">Window maximization</a>.</p>
+<h3><a class="anchor" id="workarea_33"></a>
+Query for the monitor work area</h3>
+<p>GLFW now supports querying the work area of a monitor, i.e. the area not occupied by task bars or global menu bars, with <a class="el" href="group__monitor.html#ga7387a3bdb64bfe8ebf2b9e54f5b6c9d0">glfwGetMonitorWorkarea</a>. On platforms that lack this concept, the whole area of the monitor is returned.</p>
+<p>For more information see <a class="el" href="monitor_guide.html#monitor_workarea">Work area</a>.</p>
+<h3><a class="anchor" id="transparency_33"></a>
+Transparent windows and framebuffers</h3>
+<p>GLFW now supports the creation of windows with transparent framebuffers on systems with desktop compositing enabled with the <a class="el" href="group__window.html#ga60a0578c3b9449027d683a9c6abb9f14">GLFW_TRANSPARENT_FRAMEBUFFER</a> window hint and attribute. This hint must be set before window creation and leaves any window decorations opaque.</p>
+<p>GLFW now also supports whole window transparency with <a class="el" href="group__window.html#gad09f0bd7a6307c4533b7061828480a84">glfwGetWindowOpacity</a> and <a class="el" href="group__window.html#gac31caeb3d1088831b13d2c8a156802e9">glfwSetWindowOpacity</a>. This value controls the opacity of the whole window including decorations and unlike framebuffer transparency can be changed at any time after window creation.</p>
+<p>For more information see <a class="el" href="window_guide.html#window_transparency">Window transparency</a>.</p>
+<h3><a class="anchor" id="key_scancode_33"></a>
+Query for the scancode of a key</h3>
+<p>GLFW now supports querying the platform dependent scancode of any physical key with <a class="el" href="group__input.html#ga67ddd1b7dcbbaff03e4a76c0ea67103a">glfwGetKeyScancode</a>.</p>
+<p>For more information see <a class="el" href="input_guide.html#input_key">Key input</a>.</p>
+<h3><a class="anchor" id="center_cursor_33"></a>
+Cursor centering window hint</h3>
+<p>GLFW now supports controlling whether the cursor is centered over newly created full screen windows with the <a class="el" href="window_guide.html#GLFW_CENTER_CURSOR_hint">GLFW_CENTER_CURSOR</a> window hint. It is enabled by default.</p>
+<h3><a class="anchor" id="cursor_hover_33"></a>
+Mouse cursor hover window attribute</h3>
+<p>GLFW now supports polling whether the cursor is hovering over the window content area with the <a class="el" href="window_guide.html#GLFW_HOVERED_attrib">GLFW_HOVERED</a> window attribute. This attribute corresponds to the <a class="el" href="input_guide.html#cursor_enter">cursor enter/leave</a> event.</p>
+<h3><a class="anchor" id="focusonshow_33"></a>
+Window hint and attribute for input focus on show</h3>
+<p>GLFW now has the <a class="el" href="window_guide.html#GLFW_DECORATED_hint">GLFW_FOCUS_ON_SHOW</a> window hint and attribute for controlling whether a window gets input focus when shown. It is enabled by default. It applies both when creating an visible window with <a class="el" href="group__window.html#ga5c336fddf2cbb5b92f65f10fb6043344">glfwCreateWindow</a> and when showing it with <a class="el" href="group__window.html#ga61be47917b72536a148300f46494fc66">glfwShowWindow</a>.</p>
+<p>This is a workaround for GLFW 3.0 lacking <a class="el" href="group__window.html#ga873780357abd3f3a081d71a40aae45a1">glfwFocusWindow</a> and will be corrected in the next major version.</p>

+<h3><a class="anchor" id="device_userptr_33"></a>
+Monitor and joystick user pointers</h3>
+<p>GLFW now supports setting and querying user pointers for connected monitors and joysticks with <a class="el" href="group__monitor.html#ga702750e24313a686d3637297b6e85fda">glfwSetMonitorUserPointer</a>, <a class="el" href="group__monitor.html#gac2d4209016b049222877f620010ed0d8">glfwGetMonitorUserPointer</a>, <a class="el" href="group__input.html#ga6b2f72d64d636b48a727b437cbb7489e">glfwSetJoystickUserPointer</a> and <a class="el" href="group__input.html#ga06290acb7ed23895bf26b8e981827ebd">glfwGetJoystickUserPointer</a>.</p>

+<h3><a class="anchor" id="macos_nib_33"></a>
+macOS menu bar from nib file</h3>
+<p>GLFW will now load a <code>MainMenu.nib</code> file if found in the <code>Contents/Resources</code> directory of the application bundle, as a way to replace the GLFW menu bar without recompiling GLFW. This behavior can be disabled with the <a class="el" href="intro_guide.html#GLFW_COCOA_MENUBAR_hint">GLFW_COCOA_MENUBAR</a> initialization hint.</p>
+<h3><a class="anchor" id="glext_33"></a>
+Support for more context creation extensions</h3>
+<p>The context hint <a class="el" href="window_guide.html#GLFW_SRGB_CAPABLE">GLFW_SRGB_CAPABLE</a> now supports OpenGL ES via <code>WGL_EXT_colorspace</code>, the context hint <a class="el" href="group__window.html#ga5a52fdfd46d8249c211f923675728082">GLFW_CONTEXT_NO_ERROR</a> now supports <code>WGL_ARB_create_context_no_error</code> and <code>GLX_ARB_create_context_no_error</code>, the context hint <a class="el" href="group__window.html#ga72b648a8378fe3310c7c7bbecc0f7be6">GLFW_CONTEXT_RELEASE_BEHAVIOR</a> now supports <code>EGL_KHR_context_flush_control</code> and <a class="el" href="group__context.html#ga35f1837e6f666781842483937612f163">glfwGetProcAddress</a> now supports <code>EGL_KHR_get_all_proc_addresses</code>.</p>
+<h3><a class="anchor" id="osmesa_33"></a>
+OSMesa off-screen context creation support</h3>
+<p>GLFW now supports creating off-screen OpenGL contexts using <a href="https://www.mesa3d.org/osmesa.html">OSMesa</a> by setting <a class="el" href="window_guide.html#GLFW_CONTEXT_CREATION_API_hint">GLFW_CONTEXT_CREATION_API</a> to <code>GLFW_OSMESA_CONTEXT_API</code>. Native access function have been added to retrieve the OSMesa color and depth buffers.</p>
+<p>There is also a new null backend that uses OSMesa as its native context creation API, intended for automated testing. This backend does not provide input.</p>
+<h2><a class="anchor" id="caveats_33"></a>
+Caveats for version 3.3</h2>
+<h3><a class="anchor" id="joystick_layout_33"></a>
+Layout of joysticks have changed</h3>
+<p>The way joystick elements are arranged have changed to match SDL2 in order to support SDL_GameControllerDB mappings. The layout of joysticks may change again if required for compatibility with SDL2. If you need a known and stable layout for game controllers, see if you can switch to <a class="el" href="input_guide.html#gamepad">Gamepad input</a>.</p>
+<p>Existing code that depends on a specific joystick layout will likely have to be updated.</p>
+<h3><a class="anchor" id="wait_events_33"></a>
+No window required to wait for events</h3>
+<p>The <a class="el" href="group__window.html#ga554e37d781f0a997656c26b2c56c835e">glfwWaitEvents</a> and <a class="el" href="group__window.html#ga605a178db92f1a7f1a925563ef3ea2cf">glfwWaitEventsTimeout</a> functions no longer need a window to be created to wait for events. Before version 3.3 these functions would return immediately if there were no user-created windows. On platforms where only windows can receive events, an internal helper window is used.</p>
+<p>Existing code that depends on the earlier behavior will likely have to be updated.</p>
+<h3><a class="anchor" id="gamma_ramp_size_33"></a>
+Gamma ramp size of 256 may be rejected</h3>
+<p>The documentation for versions before 3.3 stated that a gamma ramp size of 256 would always be accepted. This was never the case on X11 and could lead to artifacts on macOS. The <a class="el" href="group__monitor.html#ga6ac582625c990220785ddd34efa3169a">glfwSetGamma</a> function has been updated to always generate a ramp of the correct size.</p>
+<p>Existing code that hardcodes a size of 256 should be updated to use the size of the current ramp of a monitor when setting a new ramp for that monitor.</p>
+<h3><a class="anchor" id="xinput_deadzone_33"></a>
+Windows XInput deadzone removed</h3>
+<p>GLFW no longer applies any deadzone to the input state received from the XInput API. This was never done for any other platform joystick API so this change makes the behavior more consistent but you will need to apply your own deadzone if desired.</p>
+<h3><a class="anchor" id="x11_clipboard_33"></a>
+X11 clipboard transfer limits</h3>
+<p>GLFW now supports reading clipboard text via the <code>INCR</code> method, which removes the limit on how much text can be read with <a class="el" href="group__input.html#ga5aba1d704d9ab539282b1fbe9f18bb94">glfwGetClipboardString</a>. However, writing via this method is not yet supported, so you may not be able to write a very large string with <a class="el" href="group__input.html#gaba1f022c5eb07dfac421df34cdcd31dd">glfwSetClipboardString</a> even if you read it from the clipboard earlier.</p>
+<p>The exact size limit for writing to the clipboard is negotiated with each receiving application but is at least several tens of kilobytes. Note that only the read limit has changed. Any string that could be written before still can be.</p>
+<h3><a class="anchor" id="x11_linking_33"></a>
+X11 extension libraries are loaded dynamically</h3>
+<p>GLFW now loads all X11 extension libraries at initialization. The only X11 library you need to link against is <code>libX11</code>. The header files for the extension libraries are still required for compilation.</p>
+<p>Existing projects and makefiles that link GLFW directly against the extension libraries should still build correctly but will add these libraries as load-time dependencies.</p>
+<h3><a class="anchor" id="cmake_version_33"></a>
+CMake 3.0 or later is required</h3>
+<p>The minimum CMake version has been raised from 2.8.12 to 3.0. This is only a requirement of the GLFW CMake files. The GLFW source files do not depend on CMake.</p>
+<h2><a class="anchor" id="deprecations_33"></a>
+Deprecations in version 3.3</h2>
+<h3><a class="anchor" id="charmods_callback_33"></a>
+Character with modifiers callback</h3>
+<p>The character with modifiers callback set with <a class="el" href="group__input.html#ga0b7f4ad13c2b17435ff13b6dcfb4e43c">glfwSetCharModsCallback</a> has been deprecated and should if possible not be used.</p>
+<p>Existing code should still work but further bug fixes will likely not be made. The callback will be removed in the next major version.</p>
+<h3><a class="anchor" id="clipboard_window_33"></a>
+Window parameter to clipboard functions</h3>
+<p>The window parameter of the clipboard functions <a class="el" href="group__input.html#ga5aba1d704d9ab539282b1fbe9f18bb94">glfwGetClipboardString</a> and <a class="el" href="group__input.html#gaba1f022c5eb07dfac421df34cdcd31dd">glfwSetClipboardString</a> has been deprecated and is no longer used on any platform. On platforms where the clipboard must be owned by a specific window, an internal helper window is used.</p>
+<p>Existing code should still work unless it depends on a specific window owning the clipboard. New code may pass <code>NULL</code> as the window argument. The parameter will be removed in a future release.</p>
+<h2><a class="anchor" id="removals_33"></a>
+Removals in 3.3</h2>
+<h3><a class="anchor" id="macos_options_33"></a>
+macOS specific CMake options and macros</h3>
+<p>The <code>GLFW_USE_RETINA</code>, <code>GLFW_USE_CHDIR</code> and <code>GLFW_USE_MENUBAR</code> CMake options and the <code>_GLFW_USE_RETINA</code>, <code>_GLFW_USE_CHDIR</code> and <code>_GLFW_USE_MENUBAR</code> compile-time macros have been removed.</p>
+<p>These options and macros are replaced by the window hint <a class="el" href="window_guide.html#GLFW_COCOA_RETINA_FRAMEBUFFER_hint">GLFW_COCOA_RETINA_FRAMEBUFFER</a> and the init hints <a class="el" href="intro_guide.html#GLFW_COCOA_CHDIR_RESOURCES_hint">GLFW_COCOA_CHDIR_RESOURCES</a> and <a class="el" href="intro_guide.html#GLFW_COCOA_MENUBAR_hint">GLFW_COCOA_MENUBAR</a>.</p>
+<p>Existing projects and makefiles that set these options or define these macros during compilation of GLFW will still build but it will have no effect and the default behaviors will be used.</p>
+<h3><a class="anchor" id="vulkan_sdk_33"></a>
+LunarG Vulkan SDK dependency</h3>
+<p>The GLFW test programs that previously depended on the LunarG Vulkan SDK now instead uses a Vulkan loader generated by <a href="https://github.com/Dav1dde/glad">glad2</a>. This means the GLFW CMake files no longer look for the Vulkan SDK.</p>
+<p>Existing CMake projects that depended on the Vulkan SDK cache variables from GLFW will need to call <code>find_package(Vulkan)</code> themselves. CMake 3.7 and later already comes with a <a href="https://cmake.org/cmake/help/latest/module/FindVulkan.html">Vulkan find module</a> similar to the one GLFW previously included.</p>
+<h3><a class="anchor" id="lib_suffix_33"></a>
+CMake option LIB_SUFFIX</h3>
+<p>The <code>LIB_SUFFIX</code> CMake option has been removed. GLFW now uses the GNUInstallDirs CMake package to handle platform specific details like the library directory suffix and the <code>LIB_SUFFIX</code> CMake option has been removed.</p>
+<p>Existing projects and makefiles that set the <code>LIB_SUFFIX</code> option will use the suffix chosen by the GNUInstallDirs package and the option will be ignored.</p>
+<h3><a class="anchor" id="mir_removed_33"></a>
+Mir support</h3>
+<p>The experimental Mir support has been completely removed as the Mir project has implemented support for the Wayland protocol and is recommending that applications use that instead.</p>
+<p>Existing projects and makefiles that select Mir when compiling GLFW will fail. Use Wayland or X11 instead.</p>

The callback is set with <a class="el" href="group__input.html#ga0b7f4ad13c2b17435ff13b6dcfb4e43c">glfwSetCharModsCallback</a>. Unlike the regular character callback, this will report character events that will not result in a character being input, for example if the Control key is held down.</p>
+<dl class="section see"><dt>See also</dt><dd><a class="el" href="input_guide.html#input_char">Text input</a></dd></dl>
+<h3><a class="anchor" id="news_31_single"></a>
+Single buffered framebuffers</h3>
+<p>GLFW now supports the creation of single buffered windows, with the <a class="el" href="window_guide.html#GLFW_DOUBLEBUFFER">GLFW_DOUBLEBUFFER</a> hint.</p>
+<h3><a class="anchor" id="news_31_glext"></a>
+Macro for including extension header</h3>
+<p>GLFW now includes the extension header appropriate for the chosen OpenGL or OpenGL ES header when <a class="el" href="build_guide.html#GLFW_INCLUDE_GLEXT">GLFW_INCLUDE_GLEXT</a> is defined. GLFW does not provide these headers. They must be provided by your development environment or your OpenGL or OpenGL ES SDK.</p>

+Release notes for 3.0</h1>
+<p>These are the release notes for version 3.0. For a more detailed view including all fixed bugs see the <a href="https://www.glfw.org/changelog.html">version history</a>.</p>
+<h2><a class="anchor" id="features_30"></a>
+New features in version 3.0</h2>
+<h3><a class="anchor" id="news_30_cmake"></a>
+CMake build system</h3>
+<p>GLFW now uses the CMake build system instead of the various makefiles and project files used by earlier versions. CMake is available for all platforms supported by GLFW, is present in most package systems and can generate makefiles and/or project files for most popular development environments.</p>
+<p>For more information on how to use CMake, see the <a href="https://cmake.org/cmake/help/documentation.html">CMake manual</a>.</p>
+<h3><a class="anchor" id="news_30_multiwnd"></a>
+Multi-window support</h3>
+<p>GLFW now supports the creation of multiple windows, each with their own OpenGL or OpenGL ES context, and all window functions now take a window handle. Event callbacks are now per-window and are provided with the handle of the window that received the event. The <a class="el" href="group__context.html#ga1c04dc242268f827290fe40aa1c91157">glfwMakeContextCurrent</a> function has been added to select which context is current on a given thread.</p>
+<h3><a class="anchor" id="news_30_multimon"></a>
+Multi-monitor support</h3>
+<p>GLFW now explicitly supports multiple monitors. They can be enumerated with <a class="el" href="group__monitor.html#ga3fba51c8bd36491d4712aa5bd074a537">glfwGetMonitors</a>, queried with <a class="el" href="group__monitor.html#ga820b0ce9a5237d645ea7cbb4bd383458">glfwGetVideoModes</a>, <a class="el" href="group__monitor.html#ga102f54e7acc9149edbcf0997152df8c9">glfwGetMonitorPos</a>, <a class="el" href="group__monitor.html#ga79a34ee22ff080ca954a9663e4679daf">glfwGetMonitorName</a> and <a class="el" href="group__monitor.html#ga7d8bffc6c55539286a6bd20d32a8d7ea">glfwGetMonitorPhysicalSize</a>, and specified at window creation to make the newly created window full screen on that specific monitor.</p>
+<h3><a class="anchor" id="news_30_unicode"></a>
+Unicode support</h3>
+<p>All string arguments to GLFW functions and all strings returned by GLFW now use the UTF-8 encoding. This includes the window title, error string, clipboard text, monitor and joystick names as well as the extension function arguments (as ASCII is a subset of UTF-8).</p>
+<h3><a class="anchor" id="news_30_clipboard"></a>
+Clipboard text I/O</h3>
+<p>GLFW now supports reading and writing plain text to and from the system clipboard, with the <a class="el" href="group__input.html#ga5aba1d704d9ab539282b1fbe9f18bb94">glfwGetClipboardString</a> and <a class="el" href="group__input.html#gaba1f022c5eb07dfac421df34cdcd31dd">glfwSetClipboardString</a> functions.</p>
+<h3><a class="anchor" id="news_30_gamma"></a>
+Gamma ramp support</h3>
+<p>GLFW now supports setting and reading back the gamma ramp of monitors, with the <a class="el" href="group__monitor.html#gab7c41deb2219bde3e1eb756ddaa9ec80">glfwGetGammaRamp</a> and <a class="el" href="group__monitor.html#ga583f0ffd0d29613d8cd172b996bbf0dd">glfwSetGammaRamp</a> functions. There is also <a class="el" href="group__monitor.html#ga6ac582625c990220785ddd34efa3169a">glfwSetGamma</a>, which generates a ramp from a gamma value and then sets it.</p>
+<h3><a class="anchor" id="news_30_gles"></a>
+OpenGL ES support</h3>
+<p>GLFW now supports the creation of OpenGL ES contexts, by setting the <a class="el" href="window_guide.html#GLFW_CLIENT_API_hint">GLFW_CLIENT_API</a> hint to <code>GLFW_OPENGL_ES_API</code>, where creation of such contexts are supported. Note that GLFW <em>does not implement</em> OpenGL ES, so your driver must provide support in a way usable by GLFW. Modern Nvidia and Intel drivers support creation of OpenGL ES context using the GLX and WGL APIs, while AMD provides an EGL implementation instead.</p>
+<h3><a class="anchor" id="news_30_egl"></a>
+(Experimental) EGL support</h3>
+<p>GLFW now has an experimental EGL context creation back end that can be selected through CMake options.</p>
+<h3><a class="anchor" id="news_30_hidpi"></a>
+High-DPI support</h3>
+<p>GLFW now supports high-DPI monitors on both Windows and macOS, giving windows full resolution framebuffers where other UI elements are scaled up. To achieve this, <a class="el" href="group__window.html#ga0e2637a4161afb283f5300c7f94785c9">glfwGetFramebufferSize</a> and <a class="el" href="group__window.html#gab3fb7c3366577daef18c0023e2a8591f">glfwSetFramebufferSizeCallback</a> have been added. These work with pixels, while the rest of the GLFW API works with screen coordinates. This is important as OpenGL uses pixels, not screen coordinates.</p>
+<h3><a class="anchor" id="news_30_error"></a>
+Error callback</h3>
+<p>GLFW now has an error callback, which can provide your application with much more detailed diagnostics than was previously possible. The callback is passed an error code and a description string.</p>
+<h3><a class="anchor" id="news_30_wndptr"></a>
+Per-window user pointer</h3>
+<p>Each window now has a user-defined pointer, retrieved with <a class="el" href="group__window.html#ga17807ce0f45ac3f8bb50d6dcc59a4e06">glfwGetWindowUserPointer</a> and set with <a class="el" href="group__window.html#ga3d2fc6026e690ab31a13f78bc9fd3651">glfwSetWindowUserPointer</a>, to make it easier to integrate GLFW into C++ code.</p>
+<h3><a class="anchor" id="news_30_iconifyfun"></a>
+Window iconification callback</h3>
+<p>Each window now has a callback for iconification and restoration events, which is set with <a class="el" href="group__window.html#gac793e9efd255567b5fb8b445052cfd3e">glfwSetWindowIconifyCallback</a>.</p>
+<h3><a class="anchor" id="news_30_wndposfun"></a>
+Window position callback</h3>
+<p>Each window now has a callback for position events, which is set with <a class="el" href="group__window.html#ga08bdfbba88934f9c4f92fd757979ac74">glfwSetWindowPosCallback</a>.</p>
+<h3><a class="anchor" id="news_30_wndpos"></a>
+Window position query</h3>
+<p>The position of a window can now be retrieved using <a class="el" href="group__window.html#ga73cb526c000876fd8ddf571570fdb634">glfwGetWindowPos</a>.</p>
+<h3><a class="anchor" id="news_30_focusfun"></a>
+Window focus callback</h3>
+<p>Each windows now has a callback for focus events, which is set with <a class="el" href="group__window.html#gac2d83c4a10f071baf841f6730528e66c">glfwSetWindowFocusCallback</a>.</p>
+<h3><a class="anchor" id="news_30_enterleave"></a>
+Cursor enter/leave callback</h3>
+<p>Each window now has a callback for when the mouse cursor enters or leaves its content area, which is set with <a class="el" href="group__input.html#gad27f8ad0142c038a281466c0966817d8">glfwSetCursorEnterCallback</a>.</p>
+<h3><a class="anchor" id="news_30_wndtitle"></a>
+Initial window title</h3>
+<p>The title of a window is now specified at creation time, as one of the arguments to <a class="el" href="group__window.html#ga5c336fddf2cbb5b92f65f10fb6043344">glfwCreateWindow</a>.</p>
+<h3><a class="anchor" id="news_30_hidden"></a>
+Hidden windows</h3>
+<p>Windows can now be hidden with <a class="el" href="group__window.html#ga49401f82a1ba5f15db5590728314d47c">glfwHideWindow</a>, shown using <a class="el" href="group__window.html#ga61be47917b72536a148300f46494fc66">glfwShowWindow</a> and created initially hidden with the <a class="el" href="group__window.html#gafb3cdc45297e06d8f1eb13adc69ca6c4">GLFW_VISIBLE</a> window hint and attribute. This allows for off-screen rendering in a way compatible with most drivers, as well as moving a window to a specific position before showing it.</p>
+<h3><a class="anchor" id="news_30_undecorated"></a>
+Undecorated windows</h3>
+<p>Windowed mode windows can now be created without decorations, e.g. things like a frame, a title bar, with the <a class="el" href="group__window.html#ga21b854d36314c94d65aed84405b2f25e">GLFW_DECORATED</a> window hint and attribute. This allows for the creation of things like splash screens.</p>
+<h3><a class="anchor" id="news_30_keymods"></a>
+Modifier key bit masks</h3>
+<p><a class="el" href="group__mods.html">Modifier key bit mask</a> parameters have been added to the <a class="el" href="group__input.html#ga39893a4a7e7c3239c98d29c9e084350c">mouse button</a> and <a class="el" href="group__input.html#ga0192a232a41e4e82948217c8ba94fdfd">key</a> callbacks.</p>
+<h3><a class="anchor" id="news_30_scancode"></a>
+Platform-specific scancodes</h3>
+<p>A scancode parameter has been added to the <a class="el" href="group__input.html#ga0192a232a41e4e82948217c8ba94fdfd">key callback</a>. Keys that don't have a <a class="el" href="group__keys.html">key token</a> still get passed on with the key parameter set to <code>GLFW_KEY_UNKNOWN</code>. These scancodes will vary between machines and are intended to be used for key bindings.</p>
+<h3><a class="anchor" id="news_30_jsname"></a>
+Joystick names</h3>
+<p>The name of a joystick can now be retrieved using <a class="el" href="group__input.html#gafbe3e51f670320908cfe4e20d3e5559e">glfwGetJoystickName</a>.</p>

+<div class="textblock"><p>This guide takes you through writing a simple application using GLFW 3. The application will create a window and OpenGL context, render a rotating triangle and exit when the user closes the window or presses <em>Escape</em>. This guide will introduce a few of the most commonly used functions, but there are many more.</p>
+<p>This guide assumes no experience with earlier versions of GLFW. If you have used GLFW 2 in the past, read <a class="el" href="moving_guide.html">Moving from GLFW 2 to 3</a>, as some functions behave differently in GLFW 3.</p>
+<h1><a class="anchor" id="quick_steps"></a>
+Step by step</h1>
+<h2><a class="anchor" id="quick_include"></a>
+Including the GLFW header</h2>
+<p>In the source files of your application where you use OpenGL or GLFW, you need to include the GLFW 3 header file.</p>
+<div class="fragment"><div class="line"><span class="preprocessor">#include &lt;<a class="code" href="glfw3_8h.html">GLFW/glfw3.h</a>&gt;</span></div>
+</div><!-- fragment --><p>This defines all the constants, types and function prototypes of the GLFW API. It also includes the OpenGL header from your development environment and defines all the constants and types necessary for it to work on your platform without including any platform-specific headers.</p>
+<p>In other words:</p>
+<ul>
+<li>Do <em>not</em> include the OpenGL header yourself, as GLFW does this for you in a platform-independent way</li>
+<li>Do <em>not</em> include <code>windows.h</code> or other platform-specific headers unless you plan on using those APIs yourself</li>
+<li>If you <em>do</em> need to include such headers, include them <em>before</em> the GLFW header and it will detect this</li>
+</ul>
+<p>On some platforms supported by GLFW the OpenGL header and link library only expose older versions of OpenGL. The most extreme case is Windows, which only exposes OpenGL 1.2. The easiest way to work around this is to use an <a class="el" href="context_guide.html#context_glext_auto">extension loader library</a>.</p>
+<p>If you are using such a library then you should include its header <em>before</em> the GLFW header. This lets it replace the OpenGL header included by GLFW without conflicts. This example uses <a href="https://github.com/Dav1dde/glad">glad2</a>, but the same rule applies to all such libraries.</p>
+<div class="fragment"><div class="line"><span class="preprocessor">#include &lt;glad/gl.h&gt;</span></div>
+<div class="line"><span class="preprocessor">#include &lt;<a class="code" href="glfw3_8h.html">GLFW/glfw3.h</a>&gt;</span></div>
+</div><!-- fragment --><h2><a class="anchor" id="quick_init_term"></a>
+Initializing and terminating GLFW</h2>
+<p>Before you can use most GLFW functions, the library must be initialized. On successful initialization, <code>GLFW_TRUE</code> is returned. If an error occurred, <code>GLFW_FALSE</code> is returned.</p>
+<div class="fragment"><div class="line"><span class="keywordflow">if</span> (!<a class="code" href="group__init.html#ga317aac130a235ab08c6db0834907d85e">glfwInit</a>())</div>
+<div class="line">{</div>
+<div class="line">    <span class="comment">// Initialization failed</span></div>
+<div class="line">}</div>
+</div><!-- fragment --><p>Note that <code>GLFW_TRUE</code> and <code>GLFW_FALSE</code> are and will always be one and zero.</p>
+<p>When you are done using GLFW, typically just before the application exits, you need to terminate GLFW.</p>
+<div class="fragment"><div class="line"><a class="code" href="group__init.html#gaaae48c0a18607ea4a4ba951d939f0901">glfwTerminate</a>();</div>
+</div><!-- fragment --><p>This destroys any remaining windows and releases any other resources allocated by GLFW. After this call, you must initialize GLFW again before using any GLFW functions that require it.</p>
+<h2><a class="anchor" id="quick_capture_error"></a>
+Setting an error callback</h2>
+<p>Most events are reported through callbacks, whether it's a key being pressed, a GLFW window being moved, or an error occurring. Callbacks are C functions (or C++ static methods) that are called by GLFW with arguments describing the event.</p>
+<p>In case a GLFW function fails, an error is reported to the GLFW error callback. You can receive these reports with an error callback. This function must have the signature below but may do anything permitted in other callbacks.</p>
+<div class="fragment"><div class="line"><span class="keywordtype">void</span> error_callback(<span class="keywordtype">int</span> error, <span class="keyword">const</span> <span class="keywordtype">char</span>* description)</div>
+<div class="line">{</div>
+<div class="line">    fprintf(stderr, <span class="stringliteral">&quot;Error: %s\n&quot;</span>, description);</div>
+<div class="line">}</div>
+</div><!-- fragment --><p>Callback functions must be set, so GLFW knows to call them. The function to set the error callback is one of the few GLFW functions that may be called before initialization, which lets you be notified of errors both during and after initialization.</p>
+<div class="fragment"><div class="line"><a class="code" href="group__init.html#gaff45816610d53f0b83656092a4034f40">glfwSetErrorCallback</a>(error_callback);</div>
+</div><!-- fragment --><h2><a class="anchor" id="quick_create_window"></a>
+Creating a window and context</h2>
+<p>The window and its OpenGL context are created with a single call to <a class="el" href="group__window.html#ga5c336fddf2cbb5b92f65f10fb6043344">glfwCreateWindow</a>, which returns a handle to the created combined window and context object</p>
+<div class="fragment"><div class="line"><a class="code" href="group__window.html#ga3c96d80d363e67d13a41b5d1821f3242">GLFWwindow</a>* window = <a class="code" href="group__window.html#ga5c336fddf2cbb5b92f65f10fb6043344">glfwCreateWindow</a>(640, 480, <span class="stringliteral">&quot;My Title&quot;</span>, NULL, NULL);</div>

+<h2><a class="anchor" id="quick_render"></a>
+Rendering with OpenGL</h2>
+<p>Once you have a current OpenGL context, you can use OpenGL normally. In this tutorial, a multi-colored rotating triangle will be rendered. The framebuffer size needs to be retrieved for <code>glViewport</code>.</p>
+<div class="fragment"><div class="line"><span class="keywordtype">int</span> width, height;</div>
+<div class="line"><a class="code" href="group__window.html#ga0e2637a4161afb283f5300c7f94785c9">glfwGetFramebufferSize</a>(window, &amp;width, &amp;height);</div>
+<div class="line">glViewport(0, 0, width, height);</div>
+</div><!-- fragment --><p>You can also set a framebuffer size callback using <a class="el" href="group__window.html#gab3fb7c3366577daef18c0023e2a8591f">glfwSetFramebufferSizeCallback</a> and be notified when the size changes.</p>
+<p>Actual rendering with OpenGL is outside the scope of this tutorial, but there are <a href="https://open.gl/">many</a> <a href="https://learnopengl.com/">excellent</a> <a href="http://openglbook.com/">tutorial</a> <a href="http://ogldev.atspace.co.uk/">sites</a> that teach modern OpenGL. Some of them use GLFW to create the context and window while others use GLUT or SDL, but remember that OpenGL itself always works the same.</p>
+<h2><a class="anchor" id="quick_timer"></a>
+Reading the timer</h2>
+<p>To create smooth animation, a time source is needed. GLFW provides a timer that returns the number of seconds since initialization. The time source used is the most accurate on each platform and generally has micro- or nanosecond resolution.</p>
+<div class="fragment"><div class="line"><span class="keywordtype">double</span> time = <a class="code" href="group__input.html#gaa6cf4e7a77158a3b8fd00328b1720a4a">glfwGetTime</a>();</div>
+</div><!-- fragment --><h2><a class="anchor" id="quick_swap_buffers"></a>
+Swapping buffers</h2>
+<p>GLFW windows by default use double buffering. That means that each window has two rendering buffers; a front buffer and a back buffer. The front buffer is the one being displayed and the back buffer the one you render to.</p>
+<p>When the entire frame has been rendered, the buffers need to be swapped with one another, so the back buffer becomes the front buffer and vice versa.</p>
+<div class="fragment"><div class="line"><a class="code" href="group__window.html#ga15a5a1ee5b3c2ca6b15ca209a12efd14">glfwSwapBuffers</a>(window);</div>
+</div><!-- fragment --><p>The swap interval indicates how many frames to wait until swapping the buffers, commonly known as <em>vsync</em>. By default, the swap interval is zero, meaning buffer swapping will occur immediately. On fast machines, many of those frames will never be seen, as the screen is still only updated typically 60-75 times per second, so this wastes a lot of CPU and GPU cycles.</p>
+<p>Also, because the buffers will be swapped in the middle the screen update, leading to <a href="https://en.wikipedia.org/wiki/Screen_tearing">screen tearing</a>.</p>
+<p>For these reasons, applications will typically want to set the swap interval to one. It can be set to higher values, but this is usually not recommended, because of the input latency it leads to.</p>
+<div class="fragment"><div class="line"><a class="code" href="group__context.html#ga6d4e0cdf151b5e579bd67f13202994ed">glfwSwapInterval</a>(1);</div>
+</div><!-- fragment --><p>This function acts on the current context and will fail unless a context is current.</p>
+<h2><a class="anchor" id="quick_process_events"></a>
+Processing events</h2>
+<p>GLFW needs to communicate regularly with the window system both in order to receive events and to show that the application hasn't locked up. Event processing must be done regularly while you have visible windows and is normally done each frame after buffer swapping.</p>
+<p>There are two methods for processing pending events; polling and waiting. This example will use event polling, which processes only those events that have already been received and then returns immediately.</p>
+<div class="fragment"><div class="line"><a class="code" href="group__window.html#ga37bd57223967b4211d60ca1a0bf3c832">glfwPollEvents</a>();</div>
+</div><!-- fragment --><p>This is the best choice when rendering continually, like most games do. If instead you only need to update your rendering once you have received new input, <a class="el" href="group__window.html#ga554e37d781f0a997656c26b2c56c835e">glfwWaitEvents</a> is a better choice. It waits until at least one event has been received, putting the thread to sleep in the meantime, and then processes all received events. This saves a great deal of CPU cycles and is useful for, for example, many kinds of editing tools.</p>
+<h1><a class="anchor" id="quick_example"></a>
+Putting it together</h1>
+<p>Now that you know how to initialize GLFW, create a window and poll for keyboard input, it's possible to create a simple program.</p>
+<p>This program creates a 640 by 480 windowed mode window and starts a loop that clears the screen, renders a triangle and processes events until the user either presses <em>Escape</em> or closes the window.</p>

+</div><!-- fragment --><p> The program above can be found in the <a href="https://www.glfw.org/download.html">source package</a> as <code>examples/simple.c</code> and is compiled along with all other examples when you build GLFW. If you built GLFW from the source package then you already have this as <code>simple.exe</code> on Windows, <code>simple</code> on Linux or <code>simple.app</code> on macOS.</p>
+<p>This tutorial used only a few of the many functions GLFW provides. There are guides for each of the areas covered by GLFW. Each guide will introduce all the functions for that category.</p>
+<ul>
+<li><a class="el" href="intro_guide.html">Introduction to the API</a></li>
+<li><a class="el" href="window_guide.html">Window guide</a></li>
+<li><a class="el" href="context_guide.html">Context guide</a></li>
+<li><a class="el" href="monitor_guide.html">Monitor guide</a></li>
+<li><a class="el" href="input_guide.html">Input guide</a></li>
+</ul>
+<p>You can access reference documentation for any GLFW function by clicking it and the reference for each function links to related functions and guide sections.</p>
+<p>The tutorial ends here. Once you have written a program that uses GLFW, you will need to compile and link it. How to do that depends on the development environment you are using and is best explained by the documentation for that environment. To learn about the details that are specific to GLFW, see <a class="el" href="build_guide.html">Building applications</a>. </p>

It assumes some familiarity with Vulkan concepts like loaders, devices, queues and surfaces and leaves it to the Vulkan documentation to explain the details of Vulkan functions.</p>
+<p>To develop for Vulkan you should download the <a href="https://vulkan.lunarg.com/">LunarG Vulkan SDK</a> for your platform. Apart from headers and link libraries, they also provide the validation layers necessary for development.</p>
+<p>For details on a specific function in this category, see the <a class="el" href="group__vulkan.html">Vulkan reference</a>. There are also guides for the other areas of the GLFW API.</p>

+<h1><a class="anchor" id="vulkan_loader"></a>
+Linking against the Vulkan loader</h1>
+<p>By default, GLFW will look for the Vulkan loader on demand at runtime via its standard name (<code>vulkan-1.dll</code> on Windows, <code>libvulkan.so.1</code> on Linux and other Unix-like systems and <code>libvulkan.1.dylib</code> on macOS). This means that GLFW does not need to be linked against the loader. However, it also means that if you are using the static library form of the Vulkan loader GLFW will either fail to find it or (worse) use the wrong one.</p>
+<p>The <a class="el" href="compile_guide.html#GLFW_VULKAN_STATIC">GLFW_VULKAN_STATIC</a> CMake option makes GLFW call the Vulkan loader directly instead of dynamically loading it at runtime. Not linking against the Vulkan loader will then be a compile-time error.</p>
+<p><b>macOS:</b> Because the Vulkan loader and ICD are not installed globally on macOS, you need to set up the application bundle according to the LunarG SDK documentation. This is explained in more detail in the <a href="https://vulkan.lunarg.com/doc/sdk/latest/mac/getting_started.html">SDK documentation for macOS</a>.</p>
+<h1><a class="anchor" id="vulkan_include"></a>
+Including the Vulkan and GLFW header files</h1>
+<p>To include the Vulkan header, define <a class="el" href="build_guide.html#GLFW_INCLUDE_VULKAN">GLFW_INCLUDE_VULKAN</a> before including the GLFW header.</p>
+<div class="fragment"><div class="line"><span class="preprocessor">#define GLFW_INCLUDE_VULKAN</span></div>
+<div class="line"><span class="preprocessor">#include &lt;GLFW/glfw3.h&gt;</span></div>
+</div><!-- fragment --><p>If you instead want to include the Vulkan header from a custom location or use your own custom Vulkan header then do this before the GLFW header.</p>
+<div class="fragment"><div class="line"><span class="preprocessor">#include &lt;path/to/vulkan.h&gt;</span></div>
+<div class="line"><span class="preprocessor">#include &lt;<a class="code" href="glfw3_8h.html">GLFW/glfw3.h</a>&gt;</span></div>
+</div><!-- fragment --><p>Unless a Vulkan header is included, either by the GLFW header or above it, any GLFW functions that take or return Vulkan types will not be declared.</p>
+<p>The <code>VK_USE_PLATFORM_*_KHR</code> macros do not need to be defined for the Vulkan part of GLFW to work. Define them only if you are using these extensions directly.</p>
+<h1><a class="anchor" id="vulkan_support"></a>
+Querying for Vulkan support</h1>
+<p>If you are linking directly against the Vulkan loader then you can skip this section. The canonical desktop loader library exports all Vulkan core and Khronos extension functions, allowing them to be called directly.</p>
+<p>If you are loading the Vulkan loader dynamically instead of linking directly against it, you can check for the availability of a loader and ICD with <a class="el" href="group__vulkan.html#ga2e7f30931e02464b5bc8d0d4b6f9fe2b">glfwVulkanSupported</a>.</p>
+<div class="fragment"><div class="line"><span class="keywordflow">if</span> (<a class="code" href="group__vulkan.html#ga2e7f30931e02464b5bc8d0d4b6f9fe2b">glfwVulkanSupported</a>())</div>
+<div class="line">{</div>
+<div class="line">    <span class="comment">// Vulkan is available, at least for compute</span></div>
+<div class="line">}</div>
+</div><!-- fragment --><p>This function returns <code>GLFW_TRUE</code> if the Vulkan loader and any minimally functional ICD was found.</p>
+<p>If if one or both were not found, calling any other Vulkan related GLFW function will generate a <a class="el" href="group__errors.html#ga56882b290db23261cc6c053c40c2d08e">GLFW_API_UNAVAILABLE</a> error.</p>
+<h2><a class="anchor" id="vulkan_proc"></a>
+Querying Vulkan function pointers</h2>
+<p>To load any Vulkan core or extension function from the found loader, call <a class="el" href="group__vulkan.html#gadf228fac94c5fd8f12423ec9af9ff1e9">glfwGetInstanceProcAddress</a>. To load functions needed for instance creation, pass <code>NULL</code> as the instance.</p>
+<div class="fragment"><div class="line">PFN_vkCreateInstance pfnCreateInstance = (PFN_vkCreateInstance)</div>
+<div class="line">    <a class="code" href="group__vulkan.html#gadf228fac94c5fd8f12423ec9af9ff1e9">glfwGetInstanceProcAddress</a>(NULL, <span class="stringliteral">&quot;vkCreateInstance&quot;</span>);</div>
+</div><!-- fragment --><p>Once you have created an instance, you can load from it all other Vulkan core functions and functions from any instance extensions you enabled.</p>
+<div class="fragment"><div class="line">PFN_vkCreateDevice pfnCreateDevice = (PFN_vkCreateDevice)</div>
+<div class="line">    <a class="code" href="group__vulkan.html#gadf228fac94c5fd8f12423ec9af9ff1e9">glfwGetInstanceProcAddress</a>(instance, <span class="stringliteral">&quot;vkCreateDevice&quot;</span>);</div>
+</div><!-- fragment --><p>This function in turn calls <code>vkGetInstanceProcAddr</code>. If that fails, the function falls back to a platform-specific query of the Vulkan loader (i.e. <code>dlsym</code> or <code>GetProcAddress</code>). If that also fails, the function returns <code>NULL</code>. For more information about <code>vkGetInstanceProcAddr</code>, see the Vulkan documentation.</p>
+<p>Vulkan also provides <code>vkGetDeviceProcAddr</code> for loading device-specific versions of Vulkan function. This function can be retrieved from an instance with <a class="el" href="group__vulkan.html#gadf228fac94c5fd8f12423ec9af9ff1e9">glfwGetInstanceProcAddress</a>.</p>
+<div class="fragment"><div class="line">PFN_vkGetDeviceProcAddr pfnGetDeviceProcAddr = (PFN_vkGetDeviceProcAddr)</div>
+<div class="line">    <a class="code" href="group__vulkan.html#gadf228fac94c5fd8f12423ec9af9ff1e9">glfwGetInstanceProcAddress</a>(instance, <span class="stringliteral">&quot;vkGetDeviceProcAddr&quot;</span>);</div>
+</div><!-- fragment --><p>Device-specific functions may execute a little bit faster, due to not having to dispatch internally based on the device passed to them. For more information about <code>vkGetDeviceProcAddr</code>, see the Vulkan documentation.</p>
+<h1><a class="anchor" id="vulkan_ext"></a>
+Querying required Vulkan extensions</h1>
+<p>To do anything useful with Vulkan you need to create an instance. If you want to use Vulkan to render to a window, you must enable the instance extensions GLFW requires to create Vulkan surfaces.</p>
+<p>To query the instance extensions required, call <a class="el" href="group__vulkan.html#ga1abcbe61033958f22f63ef82008874b1">glfwGetRequiredInstanceExtensions</a>.</p>
+<div class="fragment"><div class="line">uint32_t count;</div>
+<div class="line"><span class="keyword">const</span> <span class="keywordtype">char</span>** extensions = <a class="code" href="group__vulkan.html#ga1abcbe61033958f22f63ef82008874b1">glfwGetRequiredInstanceExtensions</a>(&amp;count);</div>
+</div><!-- fragment --><p>These extensions must all be enabled when creating instances that are going to be passed to <a class="el" href="group__vulkan.html#gaff3823355cdd7e2f3f9f4d9ea9518d92">glfwGetPhysicalDevicePresentationSupport</a> and <a class="el" href="group__vulkan.html#ga1a24536bec3f80b08ead18e28e6ae965">glfwCreateWindowSurface</a>. The set of extensions will vary depending on platform and may also vary depending on graphics drivers and other factors.</p>
+<p>If it fails it will return <code>NULL</code> and GLFW will not be able to create Vulkan window surfaces. You can still use Vulkan for off-screen rendering and compute work.</p>
+<p>If successful the returned array will always include <code>VK_KHR_surface</code>, so if you don't require any additional extensions you can pass this list directly to the <code>VkInstanceCreateInfo</code> struct.</p>
+<div class="fragment"><div class="line">VkInstanceCreateInfo ici;</div>
+<div class="line"> </div>
+<div class="line">memset(&amp;ici, 0, <span class="keyword">sizeof</span>(ici));</div>
+<div class="line">ici.enabledExtensionCount = count;</div>
+<div class="line">ici.ppEnabledExtensionNames = extensions;</div>
+<div class="line">...</div>
+</div><!-- fragment --><p>Additional extensions may be required by future versions of GLFW. You should check whether any extensions you wish to enable are already in the returned array, as it is an error to specify an extension more than once in the <code>VkInstanceCreateInfo</code> struct.</p>
+<h1><a class="anchor" id="vulkan_present"></a>
+Querying for Vulkan presentation support</h1>
+<p>Not every queue family of every Vulkan device can present images to surfaces. To check whether a specific queue family of a physical device supports image presentation without first having to create a window and surface, call <a class="el" href="group__vulkan.html#gaff3823355cdd7e2f3f9f4d9ea9518d92">glfwGetPhysicalDevicePresentationSupport</a>.</p>
+<div class="fragment"><div class="line"><span class="keywordflow">if</span> (<a class="code" href="group__vulkan.html#gaff3823355cdd7e2f3f9f4d9ea9518d92">glfwGetPhysicalDevicePresentationSupport</a>(instance, physical_device, queue_family_index))</div>
+<div class="line">{</div>
+<div class="line">    <span class="comment">// Queue family supports image presentation</span></div>
+<div class="line">}</div>
+</div><!-- fragment --><p>The <code>VK_KHR_surface</code> extension additionally provides the <code>vkGetPhysicalDeviceSurfaceSupportKHR</code> function, which performs the same test on an existing Vulkan surface.</p>
+<h1><a class="anchor" id="vulkan_window"></a>
+Creating the window</h1>
+<p>Unless you will be using OpenGL or OpenGL ES with the same window as Vulkan, there is no need to create a context. You can disable context creation with the <a class="el" href="window_guide.html#GLFW_CLIENT_API_hint">GLFW_CLIENT_API</a> hint.</p>
+<div class="fragment"><div class="line"><a class="code" href="group__window.html#ga7d9c8c62384b1e2821c4dc48952d2033">glfwWindowHint</a>(<a class="code" href="group__window.html#ga649309cf72a3d3de5b1348ca7936c95b">GLFW_CLIENT_API</a>, <a class="code" href="glfw3_8h.html#a8f6dcdc968d214ff14779564f1389264">GLFW_NO_API</a>);</div>

+<h1><a class="anchor" id="vulkan_surface"></a>
+Creating a Vulkan window surface</h1>
+<p>You can create a Vulkan surface (as defined by the <code>VK_KHR_surface</code> extension) for a GLFW window with <a class="el" href="group__vulkan.html#ga1a24536bec3f80b08ead18e28e6ae965">glfwCreateWindowSurface</a>.</p>

+Window objects</h1>
+<p>The <a class="el" href="group__window.html#ga3c96d80d363e67d13a41b5d1821f3242">GLFWwindow</a> object encapsulates both a window and a context. They are created with <a class="el" href="group__window.html#ga5c336fddf2cbb5b92f65f10fb6043344">glfwCreateWindow</a> and destroyed with <a class="el" href="group__window.html#gacdf43e51376051d2c091662e9fe3d7b2">glfwDestroyWindow</a>, or <a class="el" href="group__init.html#gaaae48c0a18607ea4a4ba951d939f0901">glfwTerminate</a>, if any remain. As the window and context are inseparably linked, the object pointer is used as both a context and window handle.</p>
+<p>To see the event stream provided to the various window related callbacks, run the <code>events</code> test program.</p>
+<h2><a class="anchor" id="window_creation"></a>
+Window creation</h2>
+<p>A window and its OpenGL or OpenGL ES context are created with <a class="el" href="group__window.html#ga5c336fddf2cbb5b92f65f10fb6043344">glfwCreateWindow</a>, which returns a handle to the created window object. For example, this creates a 640 by 480 windowed mode window:</p>
+<div class="fragment"><div class="line"><a class="code" href="group__window.html#ga3c96d80d363e67d13a41b5d1821f3242">GLFWwindow</a>* window = <a class="code" href="group__window.html#ga5c336fddf2cbb5b92f65f10fb6043344">glfwCreateWindow</a>(640, 480, <span class="stringliteral">&quot;My Title&quot;</span>, NULL, NULL);</div>
+</div><!-- fragment --><p>If window creation fails, <code>NULL</code> will be returned, so it is necessary to check the return value.</p>
+<p>The window handle is passed to all window related functions and is provided to along with all input events, so event handlers can tell which window received the event.</p>
+<h3><a class="anchor" id="window_full_screen"></a>
+Full screen windows</h3>
+<p>To create a full screen window, you need to specify which monitor the window should use. In most cases, the user's primary monitor is a good choice. For more information about retrieving monitors, see <a class="el" href="monitor_guide.html#monitor_monitors">Retrieving monitors</a>.</p>
+<div class="fragment"><div class="line"><a class="code" href="group__window.html#ga3c96d80d363e67d13a41b5d1821f3242">GLFWwindow</a>* window = <a class="code" href="group__window.html#ga5c336fddf2cbb5b92f65f10fb6043344">glfwCreateWindow</a>(640, 480, <span class="stringliteral">&quot;My Title&quot;</span>, <a class="code" href="group__monitor.html#ga721867d84c6d18d6790d64d2847ca0b1">glfwGetPrimaryMonitor</a>(), NULL);</div>
+</div><!-- fragment --><p>Full screen windows cover the entire display area of a monitor, have no border or decorations.</p>
+<p>Windowed mode windows can be made full screen by setting a monitor with <a class="el" href="group__window.html#ga81c76c418af80a1cce7055bccb0ae0a7">glfwSetWindowMonitor</a>, and full screen ones can be made windowed by unsetting it with the same function.</p>
+<p>Each field of the <a class="el" href="structGLFWvidmode.html">GLFWvidmode</a> structure corresponds to a function parameter or window hint and combine to form the <em>desired video mode</em> for that window. The supported video mode most closely matching the desired video mode will be set for the chosen monitor as long as the window has input focus. For more information about retrieving video modes, see <a class="el" href="monitor_guide.html#monitor_modes">Video modes</a>.</p>

+<p>Once you have a full screen window, you can change its resolution, refresh rate and monitor with <a class="el" href="group__window.html#ga81c76c418af80a1cce7055bccb0ae0a7">glfwSetWindowMonitor</a>. If you only need change its resolution you can also call <a class="el" href="group__window.html#ga371911f12c74c504dd8d47d832d095cb">glfwSetWindowSize</a>. In all cases, the new video mode will be selected the same way as the video mode chosen by <a class="el" href="group__window.html#ga5c336fddf2cbb5b92f65f10fb6043344">glfwCreateWindow</a>. If the window has an OpenGL or OpenGL ES context, it will be unaffected.</p>
+<p>By default, the original video mode of the monitor will be restored and the window iconified if it loses input focus, to allow the user to switch back to the desktop. This behavior can be disabled with the <a class="el" href="window_guide.html#GLFW_AUTO_ICONIFY_hint">GLFW_AUTO_ICONIFY</a> window hint, for example if you wish to simultaneously cover multiple monitors with full screen windows.</p>
+<p>If a monitor is disconnected, all windows that are full screen on that monitor will be switched to windowed mode. See <a class="el" href="monitor_guide.html#monitor_event">Monitor configuration changes</a> for more information.</p>
+<h3><a class="anchor" id="window_windowed_full_screen"></a>
+"Windowed full screen" windows</h3>
+<p>If the closest match for the desired video mode is the current one, the video mode will not be changed, making window creation faster and application switching much smoother. This is sometimes called <em>windowed full screen</em> or <em>borderless full screen</em> window and counts as a full screen window. To create such a window, request the current video mode.</p>

+Window creation hints</h2>
+<p>There are a number of hints that can be set before the creation of a window and context. Some affect the window itself, others affect the framebuffer or context. These hints are set to their default values each time the library is initialized with <a class="el" href="group__init.html#ga317aac130a235ab08c6db0834907d85e">glfwInit</a>. Integer value hints can be set individually with <a class="el" href="group__window.html#ga7d9c8c62384b1e2821c4dc48952d2033">glfwWindowHint</a> and string value hints with <a class="el" href="group__window.html#ga8cb2782861c9d997bcf2dea97f363e5f">glfwWindowHintString</a>.

+<p>Some hints are platform specific. These are always valid to set on any platform but they will only affect their specific platform. Other platforms will ignore them. Setting these hints requires no platform specific headers or calls.</p>

+<p>While the size of a window is measured in screen coordinates, OpenGL works with pixels. The size you pass into <code>glViewport</code>, for example, should be in pixels.

This relies on the system DPI and scaling settings being somewhat correct.</p>
+<p>On systems where each monitors can have its own content scale, the window content scale will depend on which monitor the system considers the window to be on.</p>

+Framebuffer related attributes</h3>
+<p>GLFW does not expose attributes of the default framebuffer (i.e. the framebuffer attached to the window) as these can be queried directly with either OpenGL, OpenGL ES or Vulkan.</p>
+<p>If you are using version 3.0 or later of OpenGL or OpenGL ES, the <code>glGetFramebufferAttachmentParameteriv</code> function can be used to retrieve the number of bits for the red, green, blue, alpha, depth and stencil buffer channels. Otherwise, the <code>glGetIntegerv</code> function can be used.</p>
+<p>The number of MSAA samples are always retrieved with <code>glGetIntegerv</code>. For contexts supporting framebuffer objects, the number of samples of the currently bound framebuffer is returned.</p>

+<h1><a class="anchor" id="buffer_swap"></a>
+Buffer swapping</h1>
+<p>GLFW windows are by default double buffered. That means that you have two rendering buffers; a front buffer and a back buffer. The front buffer is the one being displayed and the back buffer the one you render to.</p>
+<p>When the entire frame has been rendered, it is time to swap the back and the front buffers in order to display what has been rendered and begin rendering a new frame. This is done with <a class="el" href="group__window.html#ga15a5a1ee5b3c2ca6b15ca209a12efd14">glfwSwapBuffers</a>.</p>
+<div class="fragment"><div class="line"><a class="code" href="group__window.html#ga15a5a1ee5b3c2ca6b15ca209a12efd14">glfwSwapBuffers</a>(window);</div>
+</div><!-- fragment --><p>Sometimes it can be useful to select when the buffer swap will occur. With the function <a class="el" href="group__context.html#ga6d4e0cdf151b5e579bd67f13202994ed">glfwSwapInterval</a> it is possible to select the minimum number of monitor refreshes the driver should wait from the time <a class="el" href="group__window.html#ga15a5a1ee5b3c2ca6b15ca209a12efd14">glfwSwapBuffers</a> was called before swapping the buffers:</p>
+<div class="fragment"><div class="line"><a class="code" href="group__context.html#ga6d4e0cdf151b5e579bd67f13202994ed">glfwSwapInterval</a>(1);</div>
+</div><!-- fragment --><p>If the interval is zero, the swap will take place immediately when <a class="el" href="group__window.html#ga15a5a1ee5b3c2ca6b15ca209a12efd14">glfwSwapBuffers</a> is called without waiting for a refresh. Otherwise at least interval retraces will pass between each buffer swap. Using a swap interval of zero can be useful for benchmarking purposes, when it is not desirable to measure the time it takes to wait for the vertical retrace. However, a swap interval of one lets you avoid tearing.</p>
+<p>Note that this may not work on all machines, as some drivers have user-controlled settings that override any swap interval the application requests.</p>
+<p>A context that supports either the <code>WGL_EXT_swap_control_tear</code> or the <code>GLX_EXT_swap_control_tear</code> extension also accepts <em>negative</em> swap intervals, which allows the driver to swap immediately even if a frame arrives a little bit late. This trades the risk of visible tears for greater framerate stability. You can check for these extensions with <a class="el" href="group__context.html#ga87425065c011cef1ebd6aac75e059dfa">glfwExtensionSupported</a>. </p>

+@page input_guide Input guide
+
+@tableofcontents
+
+This guide introduces the input related functions of GLFW.  For details on
+a specific function in this category, see the @ref input.  There are also guides
+for the other areas of GLFW.
+
+ - @ref intro_guide
+ - @ref window_guide
+ - @ref context_guide
+ - @ref vulkan_guide
+ - @ref monitor_guide
+
+GLFW provides many kinds of input.  While some can only be polled, like time, or
+only received via callbacks, like scrolling, many provide both callbacks and
+polling.  Callbacks are more work to use than polling but is less CPU intensive
+and guarantees that you do not miss state changes.
+
+All input callbacks receive a window handle.  By using the
+[window user pointer](@ref window_userptr), you can access non-global structures
+or objects from your callbacks.
+
+To get a better feel for how the various events callbacks behave, run the
+`events` test program.  It register every callback supported by GLFW and prints
+out all arguments provided for every event, along with time and sequence
+information.
+
+
+@section events Event processing
+
+GLFW needs to poll the window system for events both to provide input to the
+application and to prove to the window system that the application hasn't locked
+up.  Event processing is normally done each frame after
+[buffer swapping](@ref buffer_swap).  Even when you have no windows, event
+polling needs to be done in order to receive monitor and joystick connection
+events.
+
+There are three functions for processing pending events.  @ref glfwPollEvents,
+processes only those events that have already been received and then returns
+immediately.
+
+@code
+glfwPollEvents();
+@endcode
+
+This is the best choice when rendering continuously, like most games do.
+
+If you only need to update the contents of the window when you receive new
+input, @ref glfwWaitEvents is a better choice.
+
+@code
+glfwWaitEvents();
+@endcode
+
+It puts the thread to sleep until at least one event has been received and then
+processes all received events.  This saves a great deal of CPU cycles and is
+useful for, for example, editing tools.
+
+If you want to wait for events but have UI elements or other tasks that need
+periodic updates, @ref glfwWaitEventsTimeout lets you specify a timeout.
+
+@code
+glfwWaitEventsTimeout(0.7);
+@endcode
+
+It puts the thread to sleep until at least one event has been received, or until
+the specified number of seconds have elapsed.  It then processes any received
+events.
+
+If the main thread is sleeping in @ref glfwWaitEvents, you can wake it from
+another thread by posting an empty event to the event queue with @ref
+glfwPostEmptyEvent.
+
+@code
+glfwPostEmptyEvent();
+@endcode
+
+Do not assume that callbacks will _only_ be called in response to the above
+functions.  While it is necessary to process events in one or more of the ways
+above, window systems that require GLFW to register callbacks of its own can
+pass events to GLFW in response to many window system function calls.  GLFW will
+pass those events on to the application callbacks before returning.
+
+For example, on Windows the system function that @ref glfwSetWindowSize is
+implemented with will send window size events directly to the event callback
+that every window has and that GLFW implements for its windows.  If you have set
+a [window size callback](@ref window_size) GLFW will call it in turn with the
+new size before everything returns back out of the @ref glfwSetWindowSize call.
+
+
+@section input_keyboard Keyboard input
+
+GLFW divides keyboard input into two categories; key events and character
+events.  Key events relate to actual physical keyboard keys, whereas character
+events relate to the Unicode code points generated by pressing some of them.
+
+Keys and characters do not map 1:1.  A single key press may produce several
+characters, and a single character may require several keys to produce.  This
+may not be the case on your machine, but your users are likely not all using the
+same keyboard layout, input method or even operating system as you.
+
+
+@subsection input_key Key input
+
+If you wish to be notified when a physical key is pressed or released or when it
+repeats, set a key callback.
+
+@code
+glfwSetKeyCallback(window, key_callback);
+@endcode
+
+The callback function receives the [keyboard key](@ref keys), platform-specific
+scancode, key action and [modifier bits](@ref mods).
+
+@code
+void key_callback(GLFWwindow* window, int key, int scancode, int action, int mods)
+{
+    if (key == GLFW_KEY_E && action == GLFW_PRESS)
+        activate_airship();
+}
+@endcode
+
+The action is one of `GLFW_PRESS`, `GLFW_REPEAT` or `GLFW_RELEASE`.  The key
+will be `GLFW_KEY_UNKNOWN` if GLFW lacks a key token for it, for example
+_E-mail_ and _Play_ keys.
+
+The scancode is unique for every key, regardless of whether it has a key token.
+Scancodes are platform-specific but consistent over time, so keys will have
+different scancodes depending on the platform but they are safe to save to disk.
+You can query the scancode for any [named key](@ref keys) on the current
+platform with @ref glfwGetKeyScancode.
+
+@code
+const int scancode = glfwGetKeyScancode(GLFW_KEY_X);
+set_key_mapping(scancode, swap_weapons);
+@endcode
+
+The last reported state for every [named key](@ref keys) is also saved in
+per-window state arrays that can be polled with @ref glfwGetKey.
+
+@code
+int state = glfwGetKey(window, GLFW_KEY_E);
+if (state == GLFW_PRESS)
+{
+    activate_airship();
+}
+@endcode
+
+The returned state is one of `GLFW_PRESS` or `GLFW_RELEASE`.
+
+This function only returns cached key event state.  It does not poll the
+system for the current physical state of the key.
+
+@anchor GLFW_STICKY_KEYS
+Whenever you poll state, you risk missing the state change you are looking for.
+If a pressed key is released again before you poll its state, you will have
+missed the key press.  The recommended solution for this is to use a
+key callback, but there is also the `GLFW_STICKY_KEYS` input mode.
+
+@code
+glfwSetInputMode(window, GLFW_STICKY_KEYS, GLFW_TRUE);
+@endcode
+
+When sticky keys mode is enabled, the pollable state of a key will remain
+`GLFW_PRESS` until the state of that key is polled with @ref glfwGetKey.  Once
+it has been polled, if a key release event had been processed in the meantime,
+the state will reset to `GLFW_RELEASE`, otherwise it will remain `GLFW_PRESS`.
+
+@anchor GLFW_LOCK_KEY_MODS
+If you wish to know what the state of the Caps Lock and Num Lock keys was when
+input events were generated, set the `GLFW_LOCK_KEY_MODS` input mode.
+
+@code
+glfwSetInputMode(window, GLFW_LOCK_KEY_MODS, GLFW_TRUE);
+@endcode
+
+When this input mode is enabled, any callback that receives
+[modifier bits](@ref mods) will have the @ref GLFW_MOD_CAPS_LOCK bit set if Caps
+Lock was on when the event occurred and the @ref GLFW_MOD_NUM_LOCK bit set if
+Num Lock was on.
+
+The `GLFW_KEY_LAST` constant holds the highest value of any
+[named key](@ref keys).
+
+
+@subsection input_char Text input
+
+GLFW supports text input in the form of a stream of
+[Unicode code points](https://en.wikipedia.org/wiki/Unicode), as produced by the
+operating system text input system.  Unlike key input, text input obeys keyboard
+layouts and modifier keys and supports composing characters using
+[dead keys](https://en.wikipedia.org/wiki/Dead_key).  Once received, you can
+encode the code points into UTF-8 or any other encoding you prefer.
+
+Because an `unsigned int` is 32 bits long on all platforms supported by GLFW,
+you can treat the code point argument as native endian UTF-32.
+
+If you wish to offer regular text input, set a character callback.
+
+@code
+glfwSetCharCallback(window, character_callback);
+@endcode
+
+The callback function receives Unicode code points for key events that would
+have led to regular text input and generally behaves as a standard text field on
+that platform.
+
+@code
+void character_callback(GLFWwindow* window, unsigned int codepoint)
+{
+}
+@endcode
+
+
+@subsection input_key_name Key names
+
+If you wish to refer to keys by name, you can query the keyboard layout
+dependent name of printable keys with @ref glfwGetKeyName.
+
+@code
+const char* key_name = glfwGetKeyName(GLFW_KEY_W, 0);
+show_tutorial_hint("Press %s to move forward", key_name);
+@endcode
+
+This function can handle both [keys and scancodes](@ref input_key).  If the
+specified key is `GLFW_KEY_UNKNOWN` then the scancode is used, otherwise it is
+ignored.  This matches the behavior of the key callback, meaning the callback
+arguments can always be passed unmodified to this function.
+
+
+@section input_mouse Mouse input
+
+Mouse input comes in many forms, including mouse motion, button presses and
+scrolling offsets.  The cursor appearance can also be changed, either to
+a custom image or a standard cursor shape from the system theme.
+
+
+@subsection cursor_pos Cursor position
+
+If you wish to be notified when the cursor moves over the window, set a cursor
+position callback.
+
+@code
+glfwSetCursorPosCallback(window, cursor_position_callback);
+@endcode
+
+The callback functions receives the cursor position, measured in screen
+coordinates but relative to the top-left corner of the window content area.  On
+platforms that provide it, the full sub-pixel cursor position is passed on.
+
+@code
+static void cursor_position_callback(GLFWwindow* window, double xpos, double ypos)
+{
+}
+@endcode
+
+The cursor position is also saved per-window and can be polled with @ref
+glfwGetCursorPos.
+
+@code
+double xpos, ypos;
+glfwGetCursorPos(window, &xpos, &ypos);
+@endcode
+
+
+@subsection cursor_mode Cursor mode
+
+@anchor GLFW_CURSOR
+The `GLFW_CURSOR` input mode provides several cursor modes for special forms of
+mouse motion input.  By default, the cursor mode is `GLFW_CURSOR_NORMAL`,
+meaning the regular arrow cursor (or another cursor set with @ref glfwSetCursor)
+is used and cursor motion is not limited.
+
+If you wish to implement mouse motion based camera controls or other input
+schemes that require unlimited mouse movement, set the cursor mode to
+`GLFW_CURSOR_DISABLED`.
+
+@code
+glfwSetInputMode(window, GLFW_CURSOR, GLFW_CURSOR_DISABLED);
+@endcode
+
+This will hide the cursor and lock it to the specified window.  GLFW will then
+take care of all the details of cursor re-centering and offset calculation and
+providing the application with a virtual cursor position.  This virtual position
+is provided normally via both the cursor position callback and through polling.
+
+@note You should not implement your own version of this functionality using
+other features of GLFW.  It is not supported and will not work as robustly as
+`GLFW_CURSOR_DISABLED`.
+
+If you only wish the cursor to become hidden when it is over a window but still
+want it to behave normally, set the cursor mode to `GLFW_CURSOR_HIDDEN`.
+
+@code
+glfwSetInputMode(window, GLFW_CURSOR, GLFW_CURSOR_HIDDEN);
+@endcode
+
+This mode puts no limit on the motion of the cursor.
+
+To exit out of either of these special modes, restore the `GLFW_CURSOR_NORMAL`
+cursor mode.
+
+@code
+glfwSetInputMode(window, GLFW_CURSOR, GLFW_CURSOR_NORMAL);
+@endcode
+
+
+@anchor GLFW_RAW_MOUSE_MOTION
+@subsection raw_mouse_motion Raw mouse motion
+
+When the cursor is disabled, raw (unscaled and unaccelerated) mouse motion can
+be enabled if available.
+
+Raw mouse motion is closer to the actual motion of the mouse across a surface.
+It is not affected by the scaling and acceleration applied to the motion of the
+desktop cursor.  That processing is suitable for a cursor while raw motion is
+better for controlling for example a 3D camera.  Because of this, raw mouse
+motion is only provided when the cursor is disabled.
+
+Call @ref glfwRawMouseMotionSupported to check if the current machine provides
+raw motion and set the `GLFW_RAW_MOUSE_MOTION` input mode to enable it.  It is
+disabled by default.
+
+@code
+if (glfwRawMouseMotionSupported())
+    glfwSetInputMode(window, GLFW_RAW_MOUSE_MOTION, GLFW_TRUE);
+@endcode
+
+If supported, raw mouse motion can be enabled or disabled per-window and at any
+time but it will only be provided when the cursor is disabled.
+
+
+@subsection cursor_object Cursor objects
+
+GLFW supports creating both custom and system theme cursor images, encapsulated
+as @ref GLFWcursor objects.  They are created with @ref glfwCreateCursor or @ref
+glfwCreateStandardCursor and destroyed with @ref glfwDestroyCursor, or @ref
+glfwTerminate, if any remain.
+
+
+@subsubsection cursor_custom Custom cursor creation
+
+A custom cursor is created with @ref glfwCreateCursor, which returns a handle to
+the created cursor object.  For example, this creates a 16x16 white square
+cursor with the hot-spot in the upper-left corner:
+
+@code
+unsigned char pixels[16 * 16 * 4];
+memset(pixels, 0xff, sizeof(pixels));
+
+GLFWimage image;
+image.width = 16;
+image.height = 16;
+image.pixels = pixels;
+
+GLFWcursor* cursor = glfwCreateCursor(&image, 0, 0);
+@endcode
+
+If cursor creation fails, `NULL` will be returned, so it is necessary to check
+the return value.
+
+The image data is 32-bit, little-endian, non-premultiplied RGBA, i.e. eight bits
+per channel with the red channel first.  The pixels are arranged canonically as
+sequential rows, starting from the top-left corner.
+
+
+@subsubsection cursor_standard Standard cursor creation
+
+A cursor with a [standard shape](@ref shapes) from the current system cursor
+theme can be can be created with @ref glfwCreateStandardCursor.
+
+@code
+GLFWcursor* cursor = glfwCreateStandardCursor(GLFW_HRESIZE_CURSOR);
+@endcode
+
+These cursor objects behave in the exact same way as those created with @ref
+glfwCreateCursor except that the system cursor theme provides the actual image.
+
+
+@subsubsection cursor_destruction Cursor destruction
+
+When a cursor is no longer needed, destroy it with @ref glfwDestroyCursor.
+
+@code
+glfwDestroyCursor(cursor);
+@endcode
+
+Cursor destruction always succeeds.  If the cursor is current for any window,
+that window will revert to the default cursor.  This does not affect the cursor
+mode.  All remaining cursors are destroyed when @ref glfwTerminate is called.
+
+
+@subsubsection cursor_set Cursor setting
+
+A cursor can be set as current for a window with @ref glfwSetCursor.
+
+@code
+glfwSetCursor(window, cursor);
+@endcode
+
+Once set, the cursor image will be used as long as the system cursor is over the
+content area of the window and the [cursor mode](@ref cursor_mode) is set
+to `GLFW_CURSOR_NORMAL`.
+
+A single cursor may be set for any number of windows.
+
+To revert to the default cursor, set the cursor of that window to `NULL`.
+
+@code
+glfwSetCursor(window, NULL);
+@endcode
+
+When a cursor is destroyed, any window that has it set will revert to the
+default cursor.  This does not affect the cursor mode.
+
+
+@subsection cursor_enter Cursor enter/leave events
+
+If you wish to be notified when the cursor enters or leaves the content area of
+a window, set a cursor enter/leave callback.
+
+@code
+glfwSetCursorEnterCallback(window, cursor_enter_callback);
+@endcode
+
+The callback function receives the new classification of the cursor.
+
+@code
+void cursor_enter_callback(GLFWwindow* window, int entered)
+{
+    if (entered)
+    {
+        // The cursor entered the content area of the window
+    }
+    else
+    {
+        // The cursor left the content area of the window
+    }
+}
+@endcode
+
+You can query whether the cursor is currently inside the content area of the
+window with the [GLFW_HOVERED](@ref GLFW_HOVERED_attrib) window attribute.
+
+@code
+if (glfwGetWindowAttrib(window, GLFW_HOVERED))
+{
+    highlight_interface();
+}
+@endcode
+
+
+@subsection input_mouse_button Mouse button input
+
+If you wish to be notified when a mouse button is pressed or released, set
+a mouse button callback.
+
+@code
+glfwSetMouseButtonCallback(window, mouse_button_callback);
+@endcode
+
+The callback function receives the [mouse button](@ref buttons), button action
+and [modifier bits](@ref mods).
+
+@code
+void mouse_button_callback(GLFWwindow* window, int button, int action, int mods)
+{
+    if (button == GLFW_MOUSE_BUTTON_RIGHT && action == GLFW_PRESS)
+        popup_menu();
+}
+@endcode
+
+The action is one of `GLFW_PRESS` or `GLFW_RELEASE`.
+
+Mouse button states for [named buttons](@ref buttons) are also saved in
+per-window state arrays that can be polled with @ref glfwGetMouseButton.
+
+@code
+int state = glfwGetMouseButton(window, GLFW_MOUSE_BUTTON_LEFT);
+if (state == GLFW_PRESS)
+{
+    upgrade_cow();
+}
+@endcode
+
+The returned state is one of `GLFW_PRESS` or `GLFW_RELEASE`.
+
+This function only returns cached mouse button event state.  It does not poll
+the system for the current state of the mouse button.
+
+@anchor GLFW_STICKY_MOUSE_BUTTONS
+Whenever you poll state, you risk missing the state change you are looking for.
+If a pressed mouse button is released again before you poll its state, you will have
+missed the button press.  The recommended solution for this is to use a
+mouse button callback, but there is also the `GLFW_STICKY_MOUSE_BUTTONS`
+input mode.
+
+@code
+glfwSetInputMode(window, GLFW_STICKY_MOUSE_BUTTONS, GLFW_TRUE);
+@endcode
+
+When sticky mouse buttons mode is enabled, the pollable state of a mouse button
+will remain `GLFW_PRESS` until the state of that button is polled with @ref
+glfwGetMouseButton.  Once it has been polled, if a mouse button release event
+had been processed in the meantime, the state will reset to `GLFW_RELEASE`,
+otherwise it will remain `GLFW_PRESS`.
+
+The `GLFW_MOUSE_BUTTON_LAST` constant holds the highest value of any
+[named button](@ref buttons).
+
+
+@subsection scrolling Scroll input
+
+If you wish to be notified when the user scrolls, whether with a mouse wheel or
+touchpad gesture, set a scroll callback.
+
+@code
+glfwSetScrollCallback(window, scroll_callback);
+@endcode
+
+The callback function receives two-dimensional scroll offsets.
+
+@code
+void scroll_callback(GLFWwindow* window, double xoffset, double yoffset)
+{
+}
+@endcode
+
+A normal mouse wheel, being vertical, provides offsets along the Y-axis.
+
+
+@section joystick Joystick input
+
+The joystick functions expose connected joysticks and controllers, with both
+referred to as joysticks.  It supports up to sixteen joysticks, ranging from
+`GLFW_JOYSTICK_1`, `GLFW_JOYSTICK_2` up to and including `GLFW_JOYSTICK_16` or
+`GLFW_JOYSTICK_LAST`.  You can test whether a [joystick](@ref joysticks) is
+present with @ref glfwJoystickPresent.
+
+@code
+int present = glfwJoystickPresent(GLFW_JOYSTICK_1);
+@endcode
+
+Each joystick has zero or more axes, zero or more buttons, zero or more hats,
+a human-readable name, a user pointer and an SDL compatible GUID.
+
+When GLFW is initialized, detected joysticks are added to the beginning of
+the array.  Once a joystick is detected, it keeps its assigned ID until it is
+disconnected or the library is terminated, so as joysticks are connected and
+disconnected, there may appear gaps in the IDs.
+
+Joystick axis, button and hat state is updated when polled and does not require
+a window to be created or events to be processed.  However, if you want joystick
+connection and disconnection events reliably delivered to the
+[joystick callback](@ref joystick_event) then you must
+[process events](@ref events).
+
+To see all the properties of all connected joysticks in real-time, run the
+`joysticks` test program.
+
+
+@subsection joystick_axis Joystick axis states
+
+The positions of all axes of a joystick are returned by @ref
+glfwGetJoystickAxes.  See the reference documentation for the lifetime of the
+returned array.
+
+@code
+int count;
+const float* axes = glfwGetJoystickAxes(GLFW_JOYSTICK_5, &count);
+@endcode
+
+Each element in the returned array is a value between -1.0 and 1.0.
+
+
+@subsection joystick_button Joystick button states
+
+The states of all buttons of a joystick are returned by @ref
+glfwGetJoystickButtons.  See the reference documentation for the lifetime of the
+returned array.
+
+@code
+int count;
+const unsigned char* buttons = glfwGetJoystickButtons(GLFW_JOYSTICK_3, &count);
+@endcode
+
+Each element in the returned array is either `GLFW_PRESS` or `GLFW_RELEASE`.
+
+For backward compatibility with earlier versions that did not have @ref
+glfwGetJoystickHats, the button array by default also includes all hats.  See
+the reference documentation for @ref glfwGetJoystickButtons for details.
+
+
+@subsection joystick_hat Joystick hat states
+
+The states of all hats are returned by @ref glfwGetJoystickHats.  See the
+reference documentation for the lifetime of the returned array.
+
+@code
+int count;
+const unsigned char* hats = glfwGetJoystickHats(GLFW_JOYSTICK_7, &count);
+@endcode
+
+Each element in the returned array is one of the following:
+
+Name                  | Value
+----                  | -----
+`GLFW_HAT_CENTERED`   | 0
+`GLFW_HAT_UP`         | 1
+`GLFW_HAT_RIGHT`      | 2
+`GLFW_HAT_DOWN`       | 4
+`GLFW_HAT_LEFT`       | 8
+`GLFW_HAT_RIGHT_UP`   | `GLFW_HAT_RIGHT` \| `GLFW_HAT_UP`
+`GLFW_HAT_RIGHT_DOWN` | `GLFW_HAT_RIGHT` \| `GLFW_HAT_DOWN`
+`GLFW_HAT_LEFT_UP`    | `GLFW_HAT_LEFT` \| `GLFW_HAT_UP`
+`GLFW_HAT_LEFT_DOWN`  | `GLFW_HAT_LEFT` \| `GLFW_HAT_DOWN`
+
+The diagonal directions are bitwise combinations of the primary (up, right, down
+and left) directions and you can test for these individually by ANDing it with
+the corresponding direction.
+
+@code
+if (hats[2] & GLFW_HAT_RIGHT)
+{
+    // State of hat 2 could be right-up, right or right-down
+}
+@endcode
+
+For backward compatibility with earlier versions that did not have @ref
+glfwGetJoystickHats, all hats are by default also included in the button array.
+See the reference documentation for @ref glfwGetJoystickButtons for details.
+
+
+@subsection joystick_name Joystick name
+
+The human-readable, UTF-8 encoded name of a joystick is returned by @ref
+glfwGetJoystickName.  See the reference documentation for the lifetime of the
+returned string.
+
+@code
+const char* name = glfwGetJoystickName(GLFW_JOYSTICK_4);
+@endcode
+
+Joystick names are not guaranteed to be unique.  Two joysticks of the same model
+and make may have the same name.  Only the [joystick token](@ref joysticks) is
+guaranteed to be unique, and only until that joystick is disconnected.
+
+
+@subsection joystick_userptr Joystick user pointer
+
+Each joystick has a user pointer that can be set with @ref
+glfwSetJoystickUserPointer and queried with @ref glfwGetJoystickUserPointer.
+This can be used for any purpose you need and will not be modified by GLFW.  The
+value will be kept until the joystick is disconnected or until the library is
+terminated.
+
+The initial value of the pointer is `NULL`.
+
+
+@subsection joystick_event Joystick configuration changes
+
+If you wish to be notified when a joystick is connected or disconnected, set
+a joystick callback.
+
+@code
+glfwSetJoystickCallback(joystick_callback);
+@endcode
+
+The callback function receives the ID of the joystick that has been connected
+and disconnected and the event that occurred.
+
+@code
+void joystick_callback(int jid, int event)
+{
+    if (event == GLFW_CONNECTED)
+    {
+        // The joystick was connected
+    }
+    else if (event == GLFW_DISCONNECTED)
+    {
+        // The joystick was disconnected
+    }
+}
+@endcode
+
+For joystick connection and disconnection events to be delivered on all
+platforms, you need to call one of the [event processing](@ref events)
+functions.  Joystick disconnection may also be detected and the callback
+called by joystick functions.  The function will then return whatever it
+returns for a disconnected joystick.
+
+Only @ref glfwGetJoystickName and @ref glfwGetJoystickUserPointer will return
+useful values for a disconnected joystick and only before the monitor callback
+returns.
+
+
+@subsection gamepad Gamepad input
+
+The joystick functions provide unlabeled axes, buttons and hats, with no
+indication of where they are located on the device.  Their order may also vary
+between platforms even with the same device.
+
+To solve this problem the SDL community crowdsourced the
+[SDL_GameControllerDB](https://github.com/gabomdq/SDL_GameControllerDB) project,
+a database of mappings from many different devices to an Xbox-like gamepad.
+
+GLFW supports this mapping format and contains a copy of the mappings
+available at the time of release.  See @ref gamepad_mapping for how to update
+this at runtime.  Mappings will be assigned to joysticks automatically any time
+a joystick is connected or the mappings are updated.
+
+You can check whether a joystick is both present and has a gamepad mapping with
+@ref glfwJoystickIsGamepad.
+
+@code
+if (glfwJoystickIsGamepad(GLFW_JOYSTICK_2))
+{
+    // Use as gamepad
+}
+@endcode
+
+If you are only interested in gamepad input you can use this function instead of
+@ref glfwJoystickPresent.
+
+You can query the human-readable name provided by the gamepad mapping with @ref
+glfwGetGamepadName.  This may or may not be the same as the
+[joystick name](@ref joystick_name).
+
+@code
+const char* name = glfwGetGamepadName(GLFW_JOYSTICK_7);
+@endcode
+
+To retrieve the gamepad state of a joystick, call @ref glfwGetGamepadState.
+
+@code
+GLFWgamepadstate state;
+
+if (glfwGetGamepadState(GLFW_JOYSTICK_3, &state))
+{
+    if (state.buttons[GLFW_GAMEPAD_BUTTON_A])
+    {
+        input_jump();
+    }
+
+    input_speed(state.axes[GLFW_GAMEPAD_AXIS_RIGHT_TRIGGER]);
+}
+@endcode
+
+The @ref GLFWgamepadstate struct has two arrays; one for button states and one
+for axis states.  The values for each button and axis are the same as for the
+@ref glfwGetJoystickButtons and @ref glfwGetJoystickAxes functions, i.e.
+`GLFW_PRESS` or `GLFW_RELEASE` for buttons and -1.0 to 1.0 inclusive for axes.
+
+The sizes of the arrays and the positions within each array are fixed.
+
+The [button indices](@ref gamepad_buttons) are `GLFW_GAMEPAD_BUTTON_A`,
+`GLFW_GAMEPAD_BUTTON_B`, `GLFW_GAMEPAD_BUTTON_X`, `GLFW_GAMEPAD_BUTTON_Y`,
+`GLFW_GAMEPAD_BUTTON_LEFT_BUMPER`, `GLFW_GAMEPAD_BUTTON_RIGHT_BUMPER`,
+`GLFW_GAMEPAD_BUTTON_BACK`, `GLFW_GAMEPAD_BUTTON_START`,
+`GLFW_GAMEPAD_BUTTON_GUIDE`, `GLFW_GAMEPAD_BUTTON_LEFT_THUMB`,
+`GLFW_GAMEPAD_BUTTON_RIGHT_THUMB`, `GLFW_GAMEPAD_BUTTON_DPAD_UP`,
+`GLFW_GAMEPAD_BUTTON_DPAD_RIGHT`, `GLFW_GAMEPAD_BUTTON_DPAD_DOWN` and
+`GLFW_GAMEPAD_BUTTON_DPAD_LEFT`.
+
+For those who prefer, there are also the `GLFW_GAMEPAD_BUTTON_CROSS`,
+`GLFW_GAMEPAD_BUTTON_CIRCLE`, `GLFW_GAMEPAD_BUTTON_SQUARE` and
+`GLFW_GAMEPAD_BUTTON_TRIANGLE` aliases for the A, B, X and Y button indices.
+
+The [axis indices](@ref gamepad_axes) are `GLFW_GAMEPAD_AXIS_LEFT_X`,
+`GLFW_GAMEPAD_AXIS_LEFT_Y`, `GLFW_GAMEPAD_AXIS_RIGHT_X`,
+`GLFW_GAMEPAD_AXIS_RIGHT_Y`, `GLFW_GAMEPAD_AXIS_LEFT_TRIGGER` and
+`GLFW_GAMEPAD_AXIS_RIGHT_TRIGGER`.
+
+The `GLFW_GAMEPAD_BUTTON_LAST` and `GLFW_GAMEPAD_AXIS_LAST` constants equal
+the largest available index for each array.
+
+
+@subsection gamepad_mapping Gamepad mappings
+
+GLFW contains a copy of the mappings available in
+[SDL_GameControllerDB](https://github.com/gabomdq/SDL_GameControllerDB) at the
+time of release.  Newer ones can be added at runtime with @ref
+glfwUpdateGamepadMappings.
+
+@code
+const char* mappings = load_file_contents("game/data/gamecontrollerdb.txt");
+
+glfwUpdateGamepadMappings(mappings);
+@endcode
+
+This function supports everything from single lines up to and including the
+unmodified contents of the whole `gamecontrollerdb.txt` file.
+
+Below is a description of the mapping format.  Please keep in mind that __this
+description is not authoritative__.  The format is defined by the SDL and
+SDL_GameControllerDB projects and their documentation and code takes precedence.
+
+Each mapping is a single line of comma-separated values describing the GUID,
+name and layout of the gamepad.  Lines that do not begin with a hexadecimal
+digit are ignored.
+
+The first value is always the gamepad GUID, a 32 character long hexadecimal
+string that typically identifies its make, model, revision and the type of
+connection to the computer.  When this information is not available, the GUID is
+generated using the gamepad name.  GLFW uses the SDL 2.0.5+ GUID format but can
+convert from the older formats.
+
+The second value is always the human-readable name of the gamepad.
+
+All subsequent values are in the form `<field>:<value>` and describe the layout
+of the mapping.  These fields may not all be present and may occur in any order.
+
+The button fields are `a`, `b`, `c`, `d`, `back`, `start`, `guide`, `dpup`,
+`dpright`, `dpdown`, `dpleft`, `leftshoulder`, `rightshoulder`, `leftstick` and
+`rightstick`.
+
+The axis fields are `leftx`, `lefty`, `rightx`, `righty`, `lefttrigger` and
+`righttrigger`.
+
+The value of an axis or button field can be a joystick button, a joystick axis,
+a hat bitmask or empty.  Joystick buttons are specified as `bN`, for example
+`b2` for the third button.  Joystick axes are specified as `aN`, for example
+`a7` for the eighth button.  Joystick hat bit masks are specified as `hN.N`, for
+example `h0.8` for left on the first hat.  More than one bit may be set in the
+mask.
+
+Before an axis there may be a `+` or `-` range modifier, for example `+a3` for
+the positive half of the fourth axis.  This restricts input to only the positive
+or negative halves of the joystick axis.  After an axis or half-axis there may
+be the `~` inversion modifier, for example `a2~` or `-a7~`.  This negates the
+values of the gamepad axis.
+
+The hat bit mask match the [hat states](@ref hat_state) in the joystick
+functions.
+
+There is also the special `platform` field that specifies which platform the
+mapping is valid for.  Possible values are `Windows`, `Mac OS X` and `Linux`.
+
+Below is an example of what a gamepad mapping might look like.  It is the
+one built into GLFW for Xbox controllers accessed via the XInput API on Windows.
+This example has been broken into several lines to fit on the page, but real
+gamepad mappings must be a single line.

+
+@note GLFW does not yet support the output range and modifiers `+` and `-` that
+were recently added to SDL.  The input modifiers `+`, `-` and `~` are supported
+and described above.
+
+
+@section time Time input
+
+GLFW provides high-resolution time input, in seconds, with @ref glfwGetTime.
+
+@code
+double seconds = glfwGetTime();
+@endcode
+
+It returns the number of seconds since the library was initialized with @ref
+glfwInit.  The platform-specific time sources used typically have micro- or
+nanosecond resolution.
+
+You can modify the base time with @ref glfwSetTime.
+
+@code
+glfwSetTime(4.0);
+@endcode
+
+This sets the time to the specified time, in seconds, and it continues to count
+from there.
+
+You can also access the raw timer used to implement the functions above,
+with @ref glfwGetTimerValue.
+
+@code
+uint64_t value = glfwGetTimerValue();
+@endcode
+
+This value is in 1&nbsp;/&nbsp;frequency seconds.  The frequency of the raw
+timer varies depending on the operating system and hardware.  You can query the
+frequency, in Hz, with @ref glfwGetTimerFrequency.
+
+@code
+uint64_t frequency = glfwGetTimerFrequency();
+@endcode
+
+
+@section clipboard Clipboard input and output
+
+If the system clipboard contains a UTF-8 encoded string or if it can be
+converted to one, you can retrieve it with @ref glfwGetClipboardString.  See the
+reference documentation for the lifetime of the returned string.
+
+@code
+const char* text = glfwGetClipboardString(NULL);
+if (text)
+{
+    insert_text(text);
+}
+@endcode
+
+If the clipboard is empty or if its contents could not be converted, `NULL` is
+returned.
+
+The contents of the system clipboard can be set to a UTF-8 encoded string with
+@ref glfwSetClipboardString.
+
+@code
+glfwSetClipboardString(NULL, "A string with words in it");
+@endcode
+
+
+@section path_drop Path drop input
+
+If you wish to receive the paths of files and/or directories dropped on
+a window, set a file drop callback.
+
+@code
+glfwSetDropCallback(window, drop_callback);
+@endcode
+
+The callback function receives an array of paths encoded as UTF-8.
+
+@code
+void drop_callback(GLFWwindow* window, int count, const char** paths)
+{
+    int i;
+    for (i = 0;  i < count;  i++)
+        handle_dropped_file(paths[i]);
+}
+@endcode
+
+The path array and its strings are only valid until the file drop callback
+returns, as they may have been generated specifically for that event.  You need
+to make a deep copy of the array if you want to keep the paths.

+
+@page internals_guide Internal structure
+
+@tableofcontents
+
+There are several interfaces inside GLFW.  Each interface has its own area of
+responsibility and its own naming conventions.
+
+
+@section internals_public Public interface
+
+The most well-known is the public interface, described in the glfw3.h header
+file.  This is implemented in source files shared by all platforms and these
+files contain no platform-specific code.  This code usually ends up calling the
+platform and internal interfaces to do the actual work.
+
+The public interface uses the OpenGL naming conventions except with GLFW and
+glfw instead of GL and gl.  For struct members, where OpenGL sets no precedent,
+it use headless camel case.
+
+Examples: `glfwCreateWindow`, `GLFWwindow`, `GLFW_RED_BITS`
+
+
+@section internals_native Native interface
+
+The [native interface](@ref native) is a small set of publicly available
+but platform-specific functions, described in the glfw3native.h header file and
+used to gain access to the underlying window, context and (on some platforms)
+display handles used by the platform interface.
+
+The function names of the native interface are similar to those of the public
+interface, but embeds the name of the interface that the returned handle is
+from.
+
+Examples: `glfwGetX11Window`, `glfwGetWGLContext`
+
+
+@section internals_internal Internal interface
+
+The internal interface consists of utility functions used by all other
+interfaces.  It is shared code implemented in the same shared source files as
+the public and event interfaces.  The internal interface is described in the
+internal.h header file.
+
+The internal interface is in charge of GLFW's global data, which it stores in
+a `_GLFWlibrary` struct named `_glfw`.
+
+The internal interface uses the same style as the public interface, except all
+global names have a leading underscore.
+
+Examples: `_glfwIsValidContextConfig`, `_GLFWwindow`, `_glfw.monitorCount`
+
+
+@section internals_platform Platform interface
+
+The platform interface implements all platform-specific operations as a service
+to the public interface.  This includes event processing.  The platform
+interface is never directly called by application code and never directly calls
+application-provided callbacks.  It is also prohibited from modifying the
+platform-independent part of the internal structs.  Instead, it calls the event
+interface when events interesting to GLFW are received.
+
+The platform interface mirrors those parts of the public interface that needs to
+perform platform-specific operations on some or all platforms.  The are also
+named the same except that the glfw function prefix is replaced by
+_glfwPlatform.
+
+Examples: `_glfwPlatformCreateWindow`
+
+The platform interface also defines structs that contain platform-specific
+global and per-object state.  Their names mirror those of the internal
+interface, except that an interface-specific suffix is added.
+
+Examples: `_GLFWwindowX11`, `_GLFWcontextWGL`
+
+These structs are incorporated as members into the internal interface structs
+using special macros that name them after the specific interface used.  This
+prevents shared code from accidentally using these members.
+
+Examples: `window->win32.handle`, `_glfw.x11.display`
+
+
+@section internals_event Event interface
+
+The event interface is implemented in the same shared source files as the public
+interface and is responsible for delivering the events it receives to the
+application, either via callbacks, via window state changes or both.
+
+The function names of the event interface use a `_glfwInput` prefix and the
+ObjectEvent pattern.
+
+Examples: `_glfwInputWindowFocus`, `_glfwInputCursorPos`
+
+
+@section internals_static Static functions
+
+Static functions may be used by any interface and have no prefixes or suffixes.
+These use headless camel case.
+
+Examples: `isValidElementForJoystick`
+
+
+@section internals_config Configuration macros
+
+GLFW uses a number of configuration macros to select at compile time which
+interfaces and code paths to use.  They are defined in the glfw_config.h header file,
+which is generated from the `glfw_config.h.in` file by CMake.
+
+Configuration macros the same style as tokens in the public interface, except
+with a leading underscore.
+
+Examples: `_GLFW_WIN32`, `_GLFW_BUILD_DLL`

+
+@page intro_guide Introduction to the API
+
+@tableofcontents
+
+This guide introduces the basic concepts of GLFW and describes initialization,
+error handling and API guarantees and limitations.  For a broad but shallow
+tutorial, see @ref quick_guide instead.  For details on a specific function in
+this category, see the @ref init.
+
+There are also guides for the other areas of GLFW.
+
+ - @ref window_guide
+ - @ref context_guide
+ - @ref vulkan_guide
+ - @ref monitor_guide
+ - @ref input_guide
+
+
+@section intro_init Initialization and termination
+
+Before most GLFW functions may be called, the library must be initialized.
+This initialization checks what features are available on the machine,
+enumerates monitors and joysticks, initializes the timer and performs any
+required platform-specific initialization.
+
+Only the following functions may be called before the library has been
+successfully initialized, and only from the main thread.
+
+ - @ref glfwGetVersion
+ - @ref glfwGetVersionString
+ - @ref glfwGetError
+ - @ref glfwSetErrorCallback
+ - @ref glfwInitHint
+ - @ref glfwInit
+ - @ref glfwTerminate
+
+Calling any other function before successful initialization will cause a @ref
+GLFW_NOT_INITIALIZED error.
+
+
+@subsection intro_init_init Initializing GLFW
+
+The library is initialized with @ref glfwInit, which returns `GLFW_FALSE` if an
+error occurred.
+
+@code
+if (!glfwInit())
+{
+    // Handle initialization failure
+}
+@endcode
+
+If any part of initialization fails, any parts that succeeded are terminated as
+if @ref glfwTerminate had been called.  The library only needs to be initialized
+once and additional calls to an already initialized library will return
+`GLFW_TRUE` immediately.
+
+Once the library has been successfully initialized, it should be terminated
+before the application exits.  Modern systems are very good at freeing resources
+allocated by programs that exit, but GLFW sometimes has to change global system
+settings and these might not be restored without termination.
+
+
+@subsection init_hints Initialization hints
+
+Initialization hints are set before @ref glfwInit and affect how the library
+behaves until termination.  Hints are set with @ref glfwInitHint.
+
+@code
+glfwInitHint(GLFW_JOYSTICK_HAT_BUTTONS, GLFW_FALSE);
+@endcode
+
+The values you set hints to are never reset by GLFW, but they only take effect
+during initialization.  Once GLFW has been initialized, any values you set will
+be ignored until the library is terminated and initialized again.
+
+Some hints are platform specific.  These may be set on any platform but they
+will only affect their specific platform.  Other platforms will ignore them.
+Setting these hints requires no platform specific headers or functions.
+
+
+@subsubsection init_hints_shared Shared init hints
+
+@anchor GLFW_JOYSTICK_HAT_BUTTONS
+__GLFW_JOYSTICK_HAT_BUTTONS__ specifies whether to also expose joystick hats as
+buttons, for compatibility with earlier versions of GLFW that did not have @ref
+glfwGetJoystickHats.  Set this with @ref glfwInitHint.
+
+
+@subsubsection init_hints_osx macOS specific init hints
+
+@anchor GLFW_COCOA_CHDIR_RESOURCES_hint
+__GLFW_COCOA_CHDIR_RESOURCES__ specifies whether to set the current directory to
+the application to the `Contents/Resources` subdirectory of the application's
+bundle, if present.  Set this with @ref glfwInitHint.
+
+@anchor GLFW_COCOA_MENUBAR_hint
+__GLFW_COCOA_MENUBAR__ specifies whether to create a basic menu bar, either from
+a nib or manually, when the first window is created, which is when AppKit is
+initialized.  Set this with @ref glfwInitHint.
+
+
+@subsubsection init_hints_values Supported and default values
+
+Initialization hint             | Default value | Supported values
+------------------------------- | ------------- | ----------------
+@ref GLFW_JOYSTICK_HAT_BUTTONS  | `GLFW_TRUE`   | `GLFW_TRUE` or `GLFW_FALSE`
+@ref GLFW_COCOA_CHDIR_RESOURCES | `GLFW_TRUE`   | `GLFW_TRUE` or `GLFW_FALSE`
+@ref GLFW_COCOA_MENUBAR         | `GLFW_TRUE`   | `GLFW_TRUE` or `GLFW_FALSE`
+
+
+@subsection intro_init_terminate Terminating GLFW
+
+Before your application exits, you should terminate the GLFW library if it has
+been initialized.  This is done with @ref glfwTerminate.
+
+@code
+glfwTerminate();
+@endcode
+
+This will destroy any remaining window, monitor and cursor objects, restore any
+modified gamma ramps, re-enable the screensaver if it had been disabled and free
+any other resources allocated by GLFW.
+
+Once the library is terminated, it is as if it had never been initialized and
+you will need to initialize it again before being able to use GLFW.  If the
+library was not initialized or had already been terminated, it return
+immediately.
+
+
+@section error_handling Error handling
+
+Some GLFW functions have return values that indicate an error, but this is often
+not very helpful when trying to figure out what happened or why it occurred.
+Other functions have no return value reserved for errors, so error notification
+needs a separate channel.  Finally, far from all GLFW functions have return
+values.
+
+The last [error code](@ref errors) for the calling thread can be queried at any
+time with @ref glfwGetError.
+
+@code
+int code = glfwGetError(NULL);
+
+if (code != GLFW_NO_ERROR)
+    handle_error(code);
+@endcode
+
+If no error has occurred since the last call, @ref GLFW_NO_ERROR (zero) is
+returned.  The error is cleared before the function returns.
+
+The error code indicates the general category of the error.  Some error codes,
+such as @ref GLFW_NOT_INITIALIZED has only a single meaning, whereas others like
+@ref GLFW_PLATFORM_ERROR are used for many different errors.
+
+GLFW often has more information about an error than its general category.  You
+can retrieve a UTF-8 encoded human-readable description along with the error
+code.  If no error has occurred since the last call, the description is set to
+`NULL`.
+
+@code
+const char* description;
+int code = glfwGetError(&description);
+
+if (description)
+    display_error_message(code, description);
+@endcode
+
+The retrieved description string is only valid until the next error occurs.
+This means you must make a copy of it if you want to keep it.
+
+You can also set an error callback, which will be called each time an error
+occurs.  It is set with @ref glfwSetErrorCallback.
+
+@code
+glfwSetErrorCallback(error_callback);
+@endcode
+
+The error callback receives the same error code and human-readable description
+returned by @ref glfwGetError.
+
+@code
+void error_callback(int code, const char* description)
+{
+    display_error_message(code, description);
+}
+@endcode
+
+The error callback is called after the error is stored, so calling @ref
+glfwGetError from within the error callback returns the same values as the
+callback argument.
+
+The description string passed to the callback is only valid until the error
+callback returns.  This means you must make a copy of it if you want to keep it.
+
+__Reported errors are never fatal.__  As long as GLFW was successfully
+initialized, it will remain initialized and in a safe state until terminated
+regardless of how many errors occur.  If an error occurs during initialization
+that causes @ref glfwInit to fail, any part of the library that was initialized
+will be safely terminated.
+
+Do not rely on a currently invalid call to generate a specific error, as in the
+future that same call may generate a different error or become valid.
+
+
+@section coordinate_systems Coordinate systems
+
+GLFW has two primary coordinate systems: the _virtual screen_ and the window
+_content area_ or _content area_.  Both use the same unit: _virtual screen
+coordinates_, or just _screen coordinates_, which don't necessarily correspond
+to pixels.
+
+<img src="spaces.svg" width="90%" />
+
+Both the virtual screen and the content area coordinate systems have the X-axis
+pointing to the right and the Y-axis pointing down.
+
+Window and monitor positions are specified as the position of the upper-left
+corners of their content areas relative to the virtual screen, while cursor
+positions are specified relative to a window's content area.
+
+Because the origin of the window's content area coordinate system is also the
+point from which the window position is specified, you can translate content
+area coordinates to the virtual screen by adding the window position.  The
+window frame, when present, extends out from the content area but does not
+affect the window position.
+
+Almost all positions and sizes in GLFW are measured in screen coordinates
+relative to one of the two origins above.  This includes cursor positions,
+window positions and sizes, window frame sizes, monitor positions and video mode
+resolutions.
+
+Two exceptions are the [monitor physical size](@ref monitor_size), which is
+measured in millimetres, and [framebuffer size](@ref window_fbsize), which is
+measured in pixels.
+
+Pixels and screen coordinates may map 1:1 on your machine, but they won't on
+every other machine, for example on a Mac with a Retina display.  The ratio
+between screen coordinates and pixels may also change at run-time depending on
+which monitor the window is currently considered to be on.
+
+
+@section guarantees_limitations Guarantees and limitations
+
+This section describes the conditions under which GLFW can be expected to
+function, barring bugs in the operating system or drivers.  Use of GLFW outside
+of these limits may work on some platforms, or on some machines, or some of the
+time, or on some versions of GLFW, but it may break at any time and this will
+not be considered a bug.
+
+
+@subsection lifetime Pointer lifetimes
+
+GLFW will never free any pointer you provide to it and you must never free any
+pointer it provides to you.
+
+Many GLFW functions return pointers to dynamically allocated structures, strings
+or arrays, and some callbacks are provided with strings or arrays.  These are
+always managed by GLFW and should never be freed by the application.  The
+lifetime of these pointers is documented for each GLFW function and callback.
+If you need to keep this data, you must copy it before its lifetime expires.
+
+Many GLFW functions accept pointers to structures or strings allocated by the
+application.  These are never freed by GLFW and are always the responsibility of
+the application.  If GLFW needs to keep the data in these structures or strings,
+it is copied before the function returns.
+
+Pointer lifetimes are guaranteed not to be shortened in future minor or patch
+releases.
+
+
+@subsection reentrancy Reentrancy
+
+GLFW event processing and object destruction are not reentrant.  This means that
+the following functions must not be called from any callback function:
+
+ - @ref glfwDestroyWindow
+ - @ref glfwDestroyCursor
+ - @ref glfwPollEvents
+ - @ref glfwWaitEvents
+ - @ref glfwWaitEventsTimeout
+ - @ref glfwTerminate
+
+These functions may be made reentrant in future minor or patch releases, but
+functions not on this list will not be made non-reentrant.
+
+
+@subsection thread_safety Thread safety
+
+Most GLFW functions must only be called from the main thread (the thread that
+calls main), but some may be called from any thread once the library has been
+initialized.  Before initialization the whole library is thread-unsafe.
+
+The reference documentation for every GLFW function states whether it is limited
+to the main thread.
+
+Initialization, termination, event processing and the creation and
+destruction of windows, cursors and OpenGL and OpenGL ES contexts are all
+restricted to the main thread due to limitations of one or several platforms.
+
+Because event processing must be performed on the main thread, all callbacks
+except for the error callback will only be called on that thread.  The error
+callback may be called on any thread, as any GLFW function may generate errors.
+
+The error code and description may be queried from any thread.
+
+ - @ref glfwGetError
+
+Empty events may be posted from any thread.
+
+ - @ref glfwPostEmptyEvent
+
+The window user pointer and close flag may be read and written from any thread,
+but this is not synchronized by GLFW.
+
+ - @ref glfwGetWindowUserPointer
+ - @ref glfwSetWindowUserPointer
+ - @ref glfwWindowShouldClose
+ - @ref glfwSetWindowShouldClose
+
+These functions for working with OpenGL and OpenGL ES contexts may be called
+from any thread, but the window object is not synchronized by GLFW.
+
+ - @ref glfwMakeContextCurrent
+ - @ref glfwGetCurrentContext
+ - @ref glfwSwapBuffers
+ - @ref glfwSwapInterval
+ - @ref glfwExtensionSupported
+ - @ref glfwGetProcAddress
+
+The raw timer functions may be called from any thread.
+
+ - @ref glfwGetTimerFrequency
+ - @ref glfwGetTimerValue
+
+The regular timer may be used from any thread, but reading and writing the timer
+offset is not synchronized by GLFW.
+
+ - @ref glfwGetTime
+ - @ref glfwSetTime
+
+Library version information may be queried from any thread.
+
+ - @ref glfwGetVersion
+ - @ref glfwGetVersionString
+
+All Vulkan related functions may be called from any thread.
+
+ - @ref glfwVulkanSupported
+ - @ref glfwGetRequiredInstanceExtensions
+ - @ref glfwGetInstanceProcAddress
+ - @ref glfwGetPhysicalDevicePresentationSupport
+ - @ref glfwCreateWindowSurface
+
+GLFW uses synchronization objects internally only to manage the per-thread
+context and error states.  Additional synchronization is left to the
+application.
+
+Functions that may currently be called from any thread will always remain so,
+but functions that are currently limited to the main thread may be updated to
+allow calls from any thread in future releases.
+
+
+@subsection compatibility Version compatibility
+
+GLFW uses [Semantic Versioning](https://semver.org/).  This guarantees source
+and binary backward compatibility with earlier minor versions of the API.  This
+means that you can drop in a newer version of the library and existing programs
+will continue to compile and existing binaries will continue to run.
+
+Once a function or constant has been added, the signature of that function or
+value of that constant will remain unchanged until the next major version of
+GLFW.  No compatibility of any kind is guaranteed between major versions.
+
+Undocumented behavior, i.e. behavior that is not described in the documentation,
+may change at any time until it is documented.
+
+If the reference documentation and the implementation differ, the reference
+documentation will almost always take precedence and the implementation will be
+fixed in the next release.  The reference documentation will also take
+precedence over anything stated in a guide.
+
+
+@subsection event_order Event order
+
+The order of arrival of related events is not guaranteed to be consistent
+across platforms.  The exception is synthetic key and mouse button release
+events, which are always delivered after the window defocus event.
+
+
+@section intro_version Version management
+
+GLFW provides mechanisms for identifying what version of GLFW your application
+was compiled against as well as what version it is currently running against.
+If you are loading GLFW dynamically (not just linking dynamically), you can use
+this to verify that the library binary is compatible with your application.
+
+
+@subsection intro_version_compile Compile-time version
+
+The compile-time version of GLFW is provided by the GLFW header with the
+`GLFW_VERSION_MAJOR`, `GLFW_VERSION_MINOR` and `GLFW_VERSION_REVISION` macros.
+
+@code
+printf("Compiled against GLFW %i.%i.%i\n",
+       GLFW_VERSION_MAJOR,
+       GLFW_VERSION_MINOR,
+       GLFW_VERSION_REVISION);
+@endcode
+
+
+@subsection intro_version_runtime Run-time version
+
+The run-time version can be retrieved with @ref glfwGetVersion, a function that
+may be called regardless of whether GLFW is initialized.
+
+@code
+int major, minor, revision;
+glfwGetVersion(&major, &minor, &revision);
+
+printf("Running against GLFW %i.%i.%i\n", major, minor, revision);
+@endcode
+
+
+@subsection intro_version_string Version string
+
+GLFW 3 also provides a compile-time generated version string that describes the
+version, platform, compiler and any platform-specific compile-time options.
+This is primarily intended for submitting bug reports, to allow developers to
+see which code paths are enabled in a binary.
+
+The version string is returned by @ref glfwGetVersionString, a function that may
+be called regardless of whether GLFW is initialized.
+
+__Do not use the version string__ to parse the GLFW library version.  The @ref
+glfwGetVersion function already provides the version of the running library
+binary.
+
+The format of the string is as follows:
+ - The version of GLFW
+ - The name of the window system API
+ - The name of the context creation API
+ - Any additional options or APIs
+
+For example, when compiling GLFW 3.0 with MinGW using the Win32 and WGL
+back ends, the version string may look something like this:
+
+@code
+3.0.0 Win32 WGL MinGW
+@endcode

+@section main_intro Introduction
+
+GLFW is a free, Open Source, multi-platform library for OpenGL, OpenGL ES and
+Vulkan application development.  It provides a simple, platform-independent API
+for creating windows, contexts and surfaces, reading input, handling events, etc.
+
+@ref news_33 list new features, caveats and deprecations.
+
+@ref quick_guide is a guide for users new to GLFW.  It takes you through how to
+write a small but complete program.
+
+There are guides for each section of the API:
+
+ - @ref intro_guide – initialization, error handling and high-level design
+ - @ref window_guide – creating and working with windows and framebuffers
+ - @ref context_guide – working with OpenGL and OpenGL ES contexts
+ - @ref vulkan_guide - working with Vulkan objects and extensions
+ - @ref monitor_guide – enumerating and working with monitors and video modes
+ - @ref input_guide – receiving events, polling and processing input
+
+Once you have written a program, see @ref compile_guide and @ref build_guide.
+
+The [reference documentation](modules.html) provides more detailed information
+about specific functions.
+
+@ref moving_guide explains what has changed and how to update existing code to
+use the new API.
+
+There is a section on @ref guarantees_limitations for pointer lifetimes,
+reentrancy, thread safety, event order and backward and forward compatibility.
+
+The [FAQ](https://www.glfw.org/faq.html) answers many common questions about the
+design, implementation and use of GLFW.
+
+Finally, @ref compat_guide explains what APIs, standards and protocols GLFW uses
+and what happens when they are not present on a given machine.

+
+@page monitor_guide Monitor guide
+
+@tableofcontents
+
+This guide introduces the monitor related functions of GLFW.  For details on
+a specific function in this category, see the @ref monitor.  There are also
+guides for the other areas of GLFW.
+
+ - @ref intro_guide
+ - @ref window_guide
+ - @ref context_guide
+ - @ref vulkan_guide
+ - @ref input_guide
+
+
+@section monitor_object Monitor objects
+
+A monitor object represents a currently connected monitor and is represented as
+a pointer to the [opaque](https://en.wikipedia.org/wiki/Opaque_data_type) type
+@ref GLFWmonitor.  Monitor objects cannot be created or destroyed by the
+application and retain their addresses until the monitors they represent are
+disconnected or until the library is [terminated](@ref intro_init_terminate).
+
+Each monitor has a current video mode, a list of supported video modes,
+a virtual position, a human-readable name, an estimated physical size and
+a gamma ramp.  One of the monitors is the primary monitor.
+
+The virtual position of a monitor is in
+[screen coordinates](@ref coordinate_systems) and, together with the current
+video mode, describes the viewports that the connected monitors provide into the
+virtual desktop that spans them.
+
+To see how GLFW views your monitor setup and its available video modes, run the
+`monitors` test program.
+
+
+@subsection monitor_monitors Retrieving monitors
+
+The primary monitor is returned by @ref glfwGetPrimaryMonitor.  It is the user's
+preferred monitor and is usually the one with global UI elements like task bar
+or menu bar.
+
+@code
+GLFWmonitor* primary = glfwGetPrimaryMonitor();
+@endcode
+
+You can retrieve all currently connected monitors with @ref glfwGetMonitors.
+See the reference documentation for the lifetime of the returned array.
+
+@code
+int count;
+GLFWmonitor** monitors = glfwGetMonitors(&count);
+@endcode
+
+The primary monitor is always the first monitor in the returned array, but other
+monitors may be moved to a different index when a monitor is connected or
+disconnected.
+
+
+@subsection monitor_event Monitor configuration changes
+
+If you wish to be notified when a monitor is connected or disconnected, set
+a monitor callback.
+
+@code
+glfwSetMonitorCallback(monitor_callback);
+@endcode
+
+The callback function receives the handle for the monitor that has been
+connected or disconnected and the event that occurred.
+
+@code
+void monitor_callback(GLFWmonitor* monitor, int event)
+{
+    if (event == GLFW_CONNECTED)
+    {
+        // The monitor was connected
+    }
+    else if (event == GLFW_DISCONNECTED)
+    {
+        // The monitor was disconnected
+    }
+}
+@endcode
+
+If a monitor is disconnected, all windows that are full screen on it will be
+switched to windowed mode before the callback is called.  Only @ref
+glfwGetMonitorName and @ref glfwGetMonitorUserPointer will return useful values
+for a disconnected monitor and only before the monitor callback returns.
+
+
+@section monitor_properties Monitor properties
+
+Each monitor has a current video mode, a list of supported video modes,
+a virtual position, a content scale, a human-readable name, a user pointer, an
+estimated physical size and a gamma ramp.
+
+
+@subsection monitor_modes Video modes
+
+GLFW generally does a good job selecting a suitable video mode when you create
+a full screen window, change its video mode or make a windowed one full
+screen, but it is sometimes useful to know exactly which video modes are
+supported.
+
+Video modes are represented as @ref GLFWvidmode structures.  You can get an
+array of the video modes supported by a monitor with @ref glfwGetVideoModes.
+See the reference documentation for the lifetime of the returned array.
+
+@code
+int count;
+GLFWvidmode* modes = glfwGetVideoModes(monitor, &count);
+@endcode
+
+To get the current video mode of a monitor call @ref glfwGetVideoMode.  See the
+reference documentation for the lifetime of the returned pointer.
+
+@code
+const GLFWvidmode* mode = glfwGetVideoMode(monitor);
+@endcode
+
+The resolution of a video mode is specified in
+[screen coordinates](@ref coordinate_systems), not pixels.
+
+
+@subsection monitor_size Physical size
+
+The physical size of a monitor in millimetres, or an estimation of it, can be
+retrieved with @ref glfwGetMonitorPhysicalSize.  This has no relation to its
+current _resolution_, i.e. the width and height of its current
+[video mode](@ref monitor_modes).
+
+@code
+int width_mm, height_mm;
+glfwGetMonitorPhysicalSize(monitor, &width_mm, &height_mm);
+@endcode
+
+While this can be used to calculate the raw DPI of a monitor, this is often not
+useful.  Instead use the [monitor content scale](@ref monitor_scale) and
+[window content scale](@ref window_scale) to scale your content.
+
+
+@subsection monitor_scale Content scale
+
+The content scale for a monitor can be retrieved with @ref
+glfwGetMonitorContentScale.
+
+@code
+float xscale, yscale;
+glfwGetMonitorContentScale(monitor, &xscale, &yscale);
+@endcode
+
+The content scale is the ratio between the current DPI and the platform's
+default DPI.  This is especially important for text and any UI elements.  If the
+pixel dimensions of your UI scaled by this look appropriate on your machine then
+it should appear at a reasonable size on other machines regardless of their DPI
+and scaling settings.  This relies on the system DPI and scaling settings being
+somewhat correct.
+
+The content scale may depend on both the monitor resolution and pixel density
+and on user settings.  It may be very different from the raw DPI calculated from
+the physical size and current resolution.
+
+
+@subsection monitor_pos Virtual position
+
+The position of the monitor on the virtual desktop, in
+[screen coordinates](@ref coordinate_systems), can be retrieved with @ref
+glfwGetMonitorPos.
+
+@code
+int xpos, ypos;
+glfwGetMonitorPos(monitor, &xpos, &ypos);
+@endcode
+
+
+@subsection monitor_workarea Work area
+
+The area of a monitor not occupied by global task bars or menu bars is the work
+area.  This is specified in [screen coordinates](@ref coordinate_systems) and
+can be retrieved with @ref glfwGetMonitorWorkarea.
+
+@code
+int xpos, ypos, width, height;
+glfwGetMonitorWorkarea(monitor, &xpos, &ypos, &width, &height);
+@endcode
+
+
+@subsection monitor_name Human-readable name
+
+The human-readable, UTF-8 encoded name of a monitor is returned by @ref
+glfwGetMonitorName.  See the reference documentation for the lifetime of the
+returned string.
+
+@code
+const char* name = glfwGetMonitorName(monitor);
+@endcode
+
+Monitor names are not guaranteed to be unique.  Two monitors of the same model
+and make may have the same name.  Only the monitor handle is guaranteed to be
+unique, and only until that monitor is disconnected.
+
+
+@subsection monitor_userptr User pointer
+
+Each monitor has a user pointer that can be set with @ref
+glfwSetMonitorUserPointer and queried with @ref glfwGetMonitorUserPointer.  This
+can be used for any purpose you need and will not be modified by GLFW.  The
+value will be kept until the monitor is disconnected or until the library is
+terminated.
+
+The initial value of the pointer is `NULL`.
+
+
+@subsection monitor_gamma Gamma ramp
+
+The gamma ramp of a monitor can be set with @ref glfwSetGammaRamp, which accepts
+a monitor handle and a pointer to a @ref GLFWgammaramp structure.
+
+@code
+GLFWgammaramp ramp;
+unsigned short red[256], green[256], blue[256];
+
+ramp.size = 256;
+ramp.red = red;
+ramp.green = green;
+ramp.blue = blue;
+
+for (i = 0;  i < ramp.size;  i++)
+{
+    // Fill out gamma ramp arrays as desired
+}
+
+glfwSetGammaRamp(monitor, &ramp);
+@endcode
+
+The gamma ramp data is copied before the function returns, so there is no need
+to keep it around once the ramp has been set.
+
+It is recommended that your gamma ramp have the same size as the current gamma
+ramp for that monitor.
+
+The current gamma ramp for a monitor is returned by @ref glfwGetGammaRamp.  See
+the reference documentation for the lifetime of the returned structure.
+
+@code
+const GLFWgammaramp* ramp = glfwGetGammaRamp(monitor);
+@endcode
+
+If you wish to set a regular gamma ramp, you can have GLFW calculate it for you
+from the desired exponent with @ref glfwSetGamma, which in turn calls @ref
+glfwSetGammaRamp with the resulting ramp.
+
+@code
+glfwSetGamma(monitor, 1.0);
+@endcode
+
+To experiment with gamma correction via the @ref glfwSetGamma function, run the
+`gamma` test program.
+
+@note The software controlled gamma ramp is applied _in addition_ to the
+hardware gamma correction, which today is usually an approximation of sRGB
+gamma.  This means that setting a perfectly linear ramp, or gamma 1.0, will
+produce the default (usually sRGB-like) behavior.

+
+@page moving_guide Moving from GLFW 2 to 3
+
+@tableofcontents
+
+This is a transition guide for moving from GLFW 2 to 3.  It describes what has
+changed or been removed, but does _not_ include
+[new features](@ref news) unless they are required when moving an existing code
+base onto the new API.  For example, the new multi-monitor functions are
+required to create full screen windows with GLFW 3.
+
+
+@section moving_removed Changed and removed features
+
+@subsection moving_renamed_files Renamed library and header file
+
+The GLFW 3 header is named @ref glfw3.h and moved to the `GLFW` directory, to
+avoid collisions with the headers of other major versions.  Similarly, the GLFW
+3 library is named `glfw3,` except when it's installed as a shared library on
+Unix-like systems, where it uses the
+[soname](https://en.wikipedia.org/wiki/soname) `libglfw.so.3`.
+
+@par Old syntax
+@code
+#include <GL/glfw.h>
+@endcode
+
+@par New syntax
+@code
+#include <GLFW/glfw3.h>
+@endcode
+
+
+@subsection moving_threads Removal of threading functions
+
+The threading functions have been removed, including the per-thread sleep
+function.  They were fairly primitive, under-used, poorly integrated and took
+time away from the focus of GLFW (i.e.  context, input and window).  There are
+better threading libraries available and native threading support is available
+in both [C++11](https://en.cppreference.com/w/cpp/thread) and
+[C11](https://en.cppreference.com/w/c/thread), both of which are gaining
+traction.
+
+If you wish to use the C++11 or C11 facilities but your compiler doesn't yet
+support them, see the
+[TinyThread++](https://gitorious.org/tinythread/tinythreadpp) and
+[TinyCThread](https://github.com/tinycthread/tinycthread) projects created by
+the original author of GLFW.  These libraries implement a usable subset of the
+threading APIs in C++11 and C11, and in fact some GLFW 3 test programs use
+TinyCThread.
+
+However, GLFW 3 has better support for _use from multiple threads_ than GLFW
+2 had.  Contexts can be made current on any thread, although only a single
+thread at a time, and the documentation explicitly states which functions may be
+used from any thread and which must only be used from the main thread.
+
+@par Removed functions
+`glfwSleep`, `glfwCreateThread`, `glfwDestroyThread`, `glfwWaitThread`,
+`glfwGetThreadID`, `glfwCreateMutex`, `glfwDestroyMutex`, `glfwLockMutex`,
+`glfwUnlockMutex`, `glfwCreateCond`, `glfwDestroyCond`, `glfwWaitCond`,
+`glfwSignalCond`, `glfwBroadcastCond` and `glfwGetNumberOfProcessors`.
+
+@par Removed types
+`GLFWthreadfun`
+
+
+@subsection moving_image Removal of image and texture loading
+
+The image and texture loading functions have been removed.  They only supported
+the Targa image format, making them mostly useful for beginner level examples.
+To become of sufficiently high quality to warrant keeping them in GLFW 3, they
+would need not only to support other formats, but also modern extensions to
+OpenGL texturing.  This would either add a number of external
+dependencies (libjpeg, libpng, etc.), or force GLFW to ship with inline versions
+of these libraries.
+
+As there already are libraries doing this, it is unnecessary both to duplicate
+the work and to tie the duplicate to GLFW.  The resulting library would also be
+platform-independent, as both OpenGL and stdio are available wherever GLFW is.
+
+@par Removed functions
+`glfwReadImage`, `glfwReadMemoryImage`, `glfwFreeImage`, `glfwLoadTexture2D`,
+`glfwLoadMemoryTexture2D` and `glfwLoadTextureImage2D`.
+
+
+@subsection moving_stdcall Removal of GLFWCALL macro
+
+The `GLFWCALL` macro, which made callback functions use
+[__stdcall](https://msdn.microsoft.com/en-us/library/zxk0tw93.aspx) on Windows,
+has been removed.  GLFW is written in C, not Pascal.  Removing this macro means
+there's one less thing for application programmers to remember, i.e. the
+requirement to mark all callback functions with `GLFWCALL`.  It also simplifies
+the creation of DLLs and DLL link libraries, as there's no need to explicitly
+disable `@n` entry point suffixes.
+
+@par Old syntax
+@code
+void GLFWCALL callback_function(...);
+@endcode
+
+@par New syntax
+@code
+void callback_function(...);
+@endcode
+
+
+@subsection moving_window_handles Window handle parameters
+
+Because GLFW 3 supports multiple windows, window handle parameters have been
+added to all window-related GLFW functions and callbacks.  The handle of
+a newly created window is returned by @ref glfwCreateWindow (formerly
+`glfwOpenWindow`).  Window handles are pointers to the
+[opaque](https://en.wikipedia.org/wiki/Opaque_data_type) type @ref GLFWwindow.
+
+@par Old syntax
+@code
+glfwSetWindowTitle("New Window Title");
+@endcode
+
+@par New syntax
+@code
+glfwSetWindowTitle(window, "New Window Title");
+@endcode
+
+
+@subsection moving_monitor Explicit monitor selection
+
+GLFW 3 provides support for multiple monitors.  To request a full screen mode window,
+instead of passing `GLFW_FULLSCREEN` you specify which monitor you wish the
+window to use.  The @ref glfwGetPrimaryMonitor function returns the monitor that
+GLFW 2 would have selected, but there are many other
+[monitor functions](@ref monitor_guide).  Monitor handles are pointers to the
+[opaque](https://en.wikipedia.org/wiki/Opaque_data_type) type @ref GLFWmonitor.
+
+@par Old basic full screen
+@code
+glfwOpenWindow(640, 480, 8, 8, 8, 0, 24, 0, GLFW_FULLSCREEN);
+@endcode
+
+@par New basic full screen
+@code
+window = glfwCreateWindow(640, 480, "My Window", glfwGetPrimaryMonitor(), NULL);
+@endcode
+
+@note The framebuffer bit depth parameters of `glfwOpenWindow` have been turned
+into [window hints](@ref window_hints), but as they have been given
+[sane defaults](@ref window_hints_values) you rarely need to set these hints.
+
+
+@subsection moving_autopoll Removal of automatic event polling
+
+GLFW 3 does not automatically poll for events in @ref glfwSwapBuffers, meaning
+you need to call @ref glfwPollEvents or @ref glfwWaitEvents yourself.  Unlike
+buffer swap, which acts on a single window, the event processing functions act
+on all windows at once.
+
+@par Old basic main loop
+@code
+while (...)
+{
+    // Process input
+    // Render output
+    glfwSwapBuffers();
+}
+@endcode
+
+@par New basic main loop
+@code
+while (...)
+{
+    // Process input
+    // Render output
+    glfwSwapBuffers(window);
+    glfwPollEvents();
+}
+@endcode
+
+
+@subsection moving_context Explicit context management
+
+Each GLFW 3 window has its own OpenGL context and only you, the application
+programmer, can know which context should be current on which thread at any
+given time.  Therefore, GLFW 3 leaves that decision to you.
+
+This means that you need to call @ref glfwMakeContextCurrent after creating
+a window before you can call any OpenGL functions.
+
+
+@subsection moving_hidpi Separation of window and framebuffer sizes
+
+Window positions and sizes now use screen coordinates, which may not be the same
+as pixels on machines with high-DPI monitors.  This is important as OpenGL uses
+pixels, not screen coordinates.  For example, the rectangle specified with
+`glViewport` needs to use pixels.  Therefore, framebuffer size functions have
+been added.  You can retrieve the size of the framebuffer of a window with @ref
+glfwGetFramebufferSize function.  A framebuffer size callback has also been
+added, which can be set with @ref glfwSetFramebufferSizeCallback.
+
+@par Old basic viewport setup
+@code
+glfwGetWindowSize(&width, &height);
+glViewport(0, 0, width, height);
+@endcode
+
+@par New basic viewport setup
+@code
+glfwGetFramebufferSize(window, &width, &height);
+glViewport(0, 0, width, height);
+@endcode
+
+
+@subsection moving_window_close Window closing changes
+
+The `GLFW_OPENED` window parameter has been removed.  As long as the window has
+not been destroyed, whether through @ref glfwDestroyWindow or @ref
+glfwTerminate, the window is "open".
+
+A user attempting to close a window is now just an event like any other.  Unlike
+GLFW 2, windows and contexts created with GLFW 3 will never be destroyed unless
+you choose them to be.  Each window now has a close flag that is set to
+`GLFW_TRUE` when the user attempts to close that window.  By default, nothing else
+happens and the window stays visible.  It is then up to you to either destroy
+the window, take some other action or ignore the request.
+
+You can query the close flag at any time with @ref glfwWindowShouldClose and set
+it at any time with @ref glfwSetWindowShouldClose.
+
+@par Old basic main loop
+@code
+while (glfwGetWindowParam(GLFW_OPENED))
+{
+    ...
+}
+@endcode
+
+@par New basic main loop
+@code
+while (!glfwWindowShouldClose(window))
+{
+    ...
+}
+@endcode
+
+The close callback no longer returns a value.  Instead, it is called after the
+close flag has been set so it can override its value, if it chooses to, before
+event processing completes.  You may however not call @ref glfwDestroyWindow
+from the close callback (or any other window related callback).
+
+@par Old syntax
+@code
+int GLFWCALL window_close_callback(void);
+@endcode
+
+@par New syntax
+@code
+void window_close_callback(GLFWwindow* window);
+@endcode
+
+@note GLFW never clears the close flag to `GLFW_FALSE`, meaning you can use it
+for other reasons to close the window as well, for example the user choosing
+Quit from an in-game menu.
+
+
+@subsection moving_hints Persistent window hints
+
+The `glfwOpenWindowHint` function has been renamed to @ref glfwWindowHint.
+
+Window hints are no longer reset to their default values on window creation, but
+instead retain their values until modified by @ref glfwWindowHint or @ref
+glfwDefaultWindowHints, or until the library is terminated and re-initialized.
+
+
+@subsection moving_video_modes Video mode enumeration
+
+Video mode enumeration is now per-monitor.  The @ref glfwGetVideoModes function
+now returns all available modes for a specific monitor instead of requiring you
+to guess how large an array you need.  The `glfwGetDesktopMode` function, which
+had poorly defined behavior, has been replaced by @ref glfwGetVideoMode, which
+returns the current mode of a monitor.
+
+
+@subsection moving_char_up Removal of character actions
+
+The action parameter of the [character callback](@ref GLFWcharfun) has been
+removed.  This was an artefact of the origin of GLFW, i.e. being developed in
+English by a Swede.  However, many keyboard layouts require more than one key to
+produce characters with diacritical marks. Even the Swedish keyboard layout
+requires this for uncommon cases like ü.
+
+@par Old syntax
+@code
+void GLFWCALL character_callback(int character, int action);
+@endcode
+
+@par New syntax
+@code
+void character_callback(GLFWwindow* window, int character);
+@endcode
+
+
+@subsection moving_cursorpos Cursor position changes
+
+The `glfwGetMousePos` function has been renamed to @ref glfwGetCursorPos,
+`glfwSetMousePos` to @ref glfwSetCursorPos and `glfwSetMousePosCallback` to @ref
+glfwSetCursorPosCallback.
+
+The cursor position is now `double` instead of `int`, both for the direct
+functions and for the callback.  Some platforms can provide sub-pixel cursor
+movement and this data is now passed on to the application where available.  On
+platforms where this is not provided, the decimal part is zero.
+
+GLFW 3 only allows you to position the cursor within a window using @ref
+glfwSetCursorPos (formerly `glfwSetMousePos`) when that window is active.
+Unless the window is active, the function fails silently.
+
+
+@subsection moving_wheel Wheel position replaced by scroll offsets
+
+The `glfwGetMouseWheel` function has been removed.  Scrolling is the input of
+offsets and has no absolute position.  The mouse wheel callback has been
+replaced by a [scroll callback](@ref GLFWscrollfun) that receives
+two-dimensional floating point scroll offsets.  This allows you to receive
+precise scroll data from for example modern touchpads.
+
+@par Old syntax
+@code
+void GLFWCALL mouse_wheel_callback(int position);
+@endcode
+
+@par New syntax
+@code
+void scroll_callback(GLFWwindow* window, double xoffset, double yoffset);
+@endcode
+
+@par Removed functions
+`glfwGetMouseWheel`
+
+
+@subsection moving_repeat Key repeat action
+
+The `GLFW_KEY_REPEAT` enable has been removed and key repeat is always enabled
+for both keys and characters.  A new key action, `GLFW_REPEAT`, has been added
+to allow the [key callback](@ref GLFWkeyfun) to distinguish an initial key press
+from a repeat.  Note that @ref glfwGetKey still returns only `GLFW_PRESS` or
+`GLFW_RELEASE`.
+
+
+@subsection moving_keys Physical key input
+
+GLFW 3 key tokens map to physical keys, unlike in GLFW 2 where they mapped to
+the values generated by the current keyboard layout.  The tokens are named
+according to the values they would have using the standard US layout, but this
+is only a convenience, as most programmers are assumed to know that layout.
+This means that (for example) `GLFW_KEY_LEFT_BRACKET` is always a single key and
+is the same key in the same place regardless of what keyboard layouts the users
+of your program has.
+
+The key input facility was never meant for text input, although using it that
+way worked slightly better in GLFW 2.  If you were using it to input text, you
+should be using the character callback instead, on both GLFW 2 and 3.  This will
+give you the characters being input, as opposed to the keys being pressed.
+
+GLFW 3 has key tokens for all keys on a standard 105 key keyboard, so instead of
+having to remember whether to check for `'a'` or `'A'`, you now check for
+`GLFW_KEY_A`.
+
+
+@subsection moving_joystick Joystick function changes
+
+The `glfwGetJoystickPos` function has been renamed to @ref glfwGetJoystickAxes.
+
+The `glfwGetJoystickParam` function and the `GLFW_PRESENT`, `GLFW_AXES` and
+`GLFW_BUTTONS` tokens have been replaced by the @ref glfwJoystickPresent
+function as well as axis and button counts returned by the @ref
+glfwGetJoystickAxes and @ref glfwGetJoystickButtons functions.
+
+
+@subsection moving_mbcs Win32 MBCS support
+
+The Win32 port of GLFW 3 will not compile in
+[MBCS mode](https://msdn.microsoft.com/en-us/library/5z097dxa.aspx).
+However, because the use of the Unicode version of the Win32 API doesn't affect
+the process as a whole, but only those windows created using it, it's perfectly
+possible to call MBCS functions from other parts of the same application.
+Therefore, even if an application using GLFW has MBCS mode code, there's no need
+for GLFW itself to support it.
+
+
+@subsection moving_windows Support for versions of Windows older than XP
+
+All explicit support for version of Windows older than XP has been removed.
+There is no code that actively prevents GLFW 3 from running on these earlier
+versions, but it uses Win32 functions that those versions lack.
+
+Windows XP was released in 2001, and by now (January 2015) it has not only
+replaced almost all earlier versions of Windows, but is itself rapidly being
+replaced by Windows 7 and 8.  The MSDN library doesn't even provide
+documentation for version older than Windows 2000, making it difficult to
+maintain compatibility with these versions even if it was deemed worth the
+effort.
+
+The Win32 API has also not stood still, and GLFW 3 uses many functions only
+present on Windows XP or later.  Even supporting an OS as new as XP (new
+from the perspective of GLFW 2, which still supports Windows 95) requires
+runtime checking for a number of functions that are present only on modern
+version of Windows.
+
+
+@subsection moving_syskeys Capture of system-wide hotkeys
+
+The ability to disable and capture system-wide hotkeys like Alt+Tab has been
+removed.  Modern applications, whether they're games, scientific visualisations
+or something else, are nowadays expected to be good desktop citizens and allow
+these hotkeys to function even when running in full screen mode.
+
+
+@subsection moving_terminate Automatic termination
+
+GLFW 3 does not register @ref glfwTerminate with `atexit` at initialization,
+because `exit` calls registered functions from the calling thread and while it
+is permitted to call `exit` from any thread, @ref glfwTerminate must only be
+called from the main thread.
+
+To release all resources allocated by GLFW, you should call @ref glfwTerminate
+yourself, from the main thread, before the program terminates.  Note that this
+destroys all windows not already destroyed with @ref glfwDestroyWindow,
+invalidating any window handles you may still have.
+
+
+@subsection moving_glu GLU header inclusion
+
+GLFW 3 does not by default include the GLU header and GLU itself has been
+deprecated by [Khronos](https://en.wikipedia.org/wiki/Khronos_Group).  __New
+projects should not use GLU__, but if you need it for legacy code that
+has been moved to GLFW 3, you can request that the GLFW header includes it by
+defining @ref GLFW_INCLUDE_GLU before the inclusion of the GLFW header.
+
+@par Old syntax
+@code
+#include <GL/glfw.h>

+
+@section news_33 Release notes for version 3.3
+
+These are the release notes for version 3.3.  For a more detailed view including
+all fixed bugs see the [version history](https://www.glfw.org/changelog.html).
+
+Please review the caveats, deprecations and removals if your project was written
+against an earlier version of GLFW 3.
+
+
+@subsection features_33 New features in version 3.3
+
+@subsubsection gamepad_33 Gamepad input via SDL_GameControllerDB
+
+GLFW can now remap game controllers to a standard Xbox-like layout using
+a built-in copy of SDL_GameControllerDB.  Call @ref glfwJoystickIsGamepad to
+check if a joystick has a mapping, @ref glfwGetGamepadState to retrieve its
+input state, @ref glfwUpdateGamepadMappings to add newer mappings and @ref
+glfwGetGamepadName and @ref glfwGetJoystickGUID for mapping related information.
+
+For more information see @ref gamepad.
+
+
+@subsubsection moltenvk_33 Support for Vulkan on macOS via MoltenVK
+
+GLFW now supports [MoltenVK](https://moltengl.com/moltenvk/), a Vulkan
+implementation on top of the Metal API, and its `VK_MVK_macos_surface` window
+surface creation extension.  MoltenVK is included in the [macOS Vulkan
+SDK](https://vulkan.lunarg.com/).
+
+For more information see @ref vulkan_guide.
+
+
+@subsubsection content_scale_33 Content scale queries for DPI-aware rendering
+
+GLFW now provides content scales for windows and monitors, i.e. the ratio
+between their current DPI and the platform's default DPI, with @ref
+glfwGetWindowContentScale and @ref glfwGetMonitorContentScale.
+
+Changes of the content scale of a window can be received with the window content
+scale callback, set with @ref glfwSetWindowContentScaleCallback.
+
+The @ref GLFW_SCALE_TO_MONITOR window hint enables automatic resizing of a
+window by the content scale of the monitor it is placed, on platforms like
+Windows where this is necessary.  This takes effect both on creation and when
+the window is moved between monitors.  It is related to but different from
+[GLFW_COCOA_RETINA_FRAMEBUFFER](@ref GLFW_COCOA_RETINA_FRAMEBUFFER_hint).
+
+For more information see @ref window_scale.
+
+
+@subsubsection setwindowattrib_33 Support for updating window attributes
+
+GLFW now supports changing the [GLFW_DECORATED](@ref GLFW_DECORATED_attrib),
+[GLFW_RESIZABLE](@ref GLFW_RESIZABLE_attrib),
+[GLFW_FLOATING](@ref GLFW_FLOATING_attrib),
+[GLFW_AUTO_ICONIFY](@ref GLFW_AUTO_ICONIFY_attrib) and
+[GLFW_FOCUS_ON_SHOW](@ref GLFW_FOCUS_ON_SHOW_attrib) attributes for existing
+windows with @ref glfwSetWindowAttrib.
+
+For more information see @ref window_attribs.
+
+
+@subsubsection raw_motion_33 Support for raw mouse motion
+
+GLFW now supports raw (unscaled and unaccelerated) mouse motion in disabled
+cursor mode with the [GLFW_RAW_MOUSE_MOTION](@ref GLFW_RAW_MOUSE_MOTION) input
+mode.  Raw mouse motion input is not yet implemented on macOS.  Call @ref
+glfwRawMouseMotionSupported to check if GLFW can provide raw mouse motion on the
+current system.
+
+For more information see @ref raw_mouse_motion.
+
+
+@subsubsection joysticks_33 Joystick hats
+
+GLFW can now return the state of hats (i.e. POVs or D-pads) of a joystick with
+@ref glfwGetJoystickHats.  For compatibility, hats are also exposed as buttons.
+This can be disabled with the @ref GLFW_JOYSTICK_HAT_BUTTONS initialization
+hint.
+
+For more information see @ref joystick_hat.
+
+
+@subsubsection geterror_33 Error query
+
+GLFW now supports querying the last error code for the calling thread and its
+human-readable description with @ref glfwGetError.  This can be used instead of
+or together with the error callback.
+
+For more information see @ref error_handling.
+
+
+@subsubsection init_hints_33 Support for initialization hints
+
+GLFW now supports setting library initialization hints with @ref glfwInitHint.
+These must be set before initialization to take effect.  Some of these hints are
+platform specific but are safe to set on any platform.
+
+For more information see @ref init_hints.
+
+
+@subsubsection attention_33 User attention request
+
+GLFW now supports requesting user attention with @ref
+glfwRequestWindowAttention.  Where possible this calls attention to the
+specified window.  On platforms like macOS it calls attention to the whole
+application.
+
+For more information see @ref window_attention.
+
+
+@subsubsection maximize_33 Window maximization callback
+
+GLFW now supports notifying the application that the window has been maximized
+@ref glfwSetWindowMaximizeCallback.  This is called both when the window was
+maximized by the user and when it was done with @ref glfwMaximizeWindow.
+
+For more information see @ref window_maximize.
+
+
+@subsubsection workarea_33 Query for the monitor work area
+
+GLFW now supports querying the work area of a monitor, i.e. the area not
+occupied by task bars or global menu bars, with @ref glfwGetMonitorWorkarea.  On
+platforms that lack this concept, the whole area of the monitor is returned.
+
+For more information see @ref monitor_workarea.
+
+
+@subsubsection transparency_33 Transparent windows and framebuffers
+
+GLFW now supports the creation of windows with transparent framebuffers on
+systems with desktop compositing enabled with the @ref
+GLFW_TRANSPARENT_FRAMEBUFFER window hint and attribute.  This hint must be set
+before window creation and leaves any window decorations opaque.
+
+GLFW now also supports whole window transparency with @ref glfwGetWindowOpacity
+and @ref glfwSetWindowOpacity.  This value controls the opacity of the whole
+window including decorations and unlike framebuffer transparency can be changed
+at any time after window creation.
+
+For more information see @ref window_transparency.
+
+
+@subsubsection key_scancode_33 Query for the scancode of a key
+
+GLFW now supports querying the platform dependent scancode of any physical key
+with @ref glfwGetKeyScancode.
+
+For more information see @ref input_key.
+
+
+@subsubsection center_cursor_33 Cursor centering window hint
+
+GLFW now supports controlling whether the cursor is centered over newly created
+full screen windows with the [GLFW_CENTER_CURSOR](@ref GLFW_CENTER_CURSOR_hint)
+window hint.  It is enabled by default.
+
+
+@subsubsection cursor_hover_33 Mouse cursor hover window attribute
+
+GLFW now supports polling whether the cursor is hovering over the window content
+area with the [GLFW_HOVERED](@ref GLFW_HOVERED_attrib) window attribute.  This
+attribute corresponds to the [cursor enter/leave](@ref cursor_enter) event.
+
+
+@subsubsection focusonshow_33 Window hint and attribute for input focus on show
+
+GLFW now has the [GLFW_FOCUS_ON_SHOW](@ref GLFW_DECORATED_hint) window hint and
+attribute for controlling whether a window gets input focus when shown.  It is
+enabled by default.  It applies both when creating an visible window with @ref
+glfwCreateWindow and when showing it with @ref glfwShowWindow.
+
+This is a workaround for GLFW 3.0 lacking @ref glfwFocusWindow and will be
+corrected in the next major version.
+
+For more information see @ref window_hide.
+
+
+@subsubsection device_userptr_33 Monitor and joystick user pointers
+
+GLFW now supports setting and querying user pointers for connected monitors and
+joysticks with @ref glfwSetMonitorUserPointer, @ref glfwGetMonitorUserPointer,
+@ref glfwSetJoystickUserPointer and @ref glfwGetJoystickUserPointer.
+
+For more information see @ref monitor_userptr and @ref joystick_userptr.
+
+
+@subsubsection macos_nib_33 macOS menu bar from nib file
+
+GLFW will now load a `MainMenu.nib` file if found in the `Contents/Resources`
+directory of the application bundle, as a way to replace the GLFW menu bar
+without recompiling GLFW.  This behavior can be disabled with the
+[GLFW_COCOA_MENUBAR](@ref GLFW_COCOA_MENUBAR_hint) initialization hint.
+
+
+@subsubsection glext_33 Support for more context creation extensions
+
+The context hint @ref GLFW_SRGB_CAPABLE now supports OpenGL ES via
+`WGL_EXT_colorspace`, the context hint @ref GLFW_CONTEXT_NO_ERROR now supports
+`WGL_ARB_create_context_no_error` and `GLX_ARB_create_context_no_error`, the
+context hint @ref GLFW_CONTEXT_RELEASE_BEHAVIOR now supports
+`EGL_KHR_context_flush_control` and @ref glfwGetProcAddress now supports
+`EGL_KHR_get_all_proc_addresses`.
+
+
+@subsubsection osmesa_33 OSMesa off-screen context creation support
+
+GLFW now supports creating off-screen OpenGL contexts using
+[OSMesa](https://www.mesa3d.org/osmesa.html) by setting
+[GLFW_CONTEXT_CREATION_API](@ref GLFW_CONTEXT_CREATION_API_hint) to
+`GLFW_OSMESA_CONTEXT_API`.  Native access function have been added to retrieve
+the OSMesa color and depth buffers.
+
+There is also a new null backend that uses OSMesa as its native context
+creation API, intended for automated testing.  This backend does not provide
+input.
+
+
+@subsection caveats_33 Caveats for version 3.3
+
+@subsubsection joystick_layout_33 Layout of joysticks have changed
+
+The way joystick elements are arranged have changed to match SDL2 in order to
+support SDL_GameControllerDB mappings.  The layout of joysticks may
+change again if required for compatibility with SDL2.  If you need a known and
+stable layout for game controllers, see if you can switch to @ref gamepad.
+
+Existing code that depends on a specific joystick layout will likely have to be
+updated.
+
+
+@subsubsection wait_events_33 No window required to wait for events
+
+The @ref glfwWaitEvents and @ref glfwWaitEventsTimeout functions no longer need
+a window to be created to wait for events.  Before version 3.3 these functions
+would return immediately if there were no user-created windows.  On platforms
+where only windows can receive events, an internal helper window is used.
+
+Existing code that depends on the earlier behavior will likely have to be
+updated.
+
+
+@subsubsection gamma_ramp_size_33 Gamma ramp size of 256 may be rejected
+
+The documentation for versions before 3.3 stated that a gamma ramp size of 256
+would always be accepted.  This was never the case on X11 and could lead to
+artifacts on macOS.  The @ref glfwSetGamma function has been updated to always
+generate a ramp of the correct size.
+
+Existing code that hardcodes a size of 256 should be updated to use the size of
+the current ramp of a monitor when setting a new ramp for that monitor.
+
+
+@subsubsection xinput_deadzone_33 Windows XInput deadzone removed
+
+GLFW no longer applies any deadzone to the input state received from the XInput
+API.  This was never done for any other platform joystick API so this change
+makes the behavior more consistent but you will need to apply your own deadzone
+if desired.
+
+
+@subsubsection x11_clipboard_33 X11 clipboard transfer limits
+
+GLFW now supports reading clipboard text via the `INCR` method, which removes
+the limit on how much text can be read with @ref glfwGetClipboardString.
+However, writing via this method is not yet supported, so you may not be able to
+write a very large string with @ref glfwSetClipboardString even if you read it
+from the clipboard earlier.
+
+The exact size limit for writing to the clipboard is negotiated with each
+receiving application but is at least several tens of kilobytes.  Note that only
+the read limit has changed.  Any string that could be written before still can
+be.
+
+
+@subsubsection x11_linking_33 X11 extension libraries are loaded dynamically
+
+GLFW now loads all X11 extension libraries at initialization.  The only X11
+library you need to link against is `libX11`.  The header files for the
+extension libraries are still required for compilation.
+
+Existing projects and makefiles that link GLFW directly against the extension
+libraries should still build correctly but will add these libraries as load-time
+dependencies.
+
+
+@subsubsection cmake_version_33 CMake 3.0 or later is required
+
+The minimum CMake version has been raised from 2.8.12 to 3.0.  This is only
+a requirement of the GLFW CMake files.  The GLFW source files do not depend on
+CMake.
+
+
+@subsection deprecations_33 Deprecations in version 3.3
+
+@subsubsection charmods_callback_33 Character with modifiers callback
+
+The character with modifiers callback set with @ref glfwSetCharModsCallback has
+been deprecated and should if possible not be used.
+
+Existing code should still work but further bug fixes will likely not be made.
+The callback will be removed in the next major version.
+
+
+@subsubsection clipboard_window_33 Window parameter to clipboard functions
+
+The window parameter of the clipboard functions @ref glfwGetClipboardString and
+@ref glfwSetClipboardString has been deprecated and is no longer used on any
+platform.  On platforms where the clipboard must be owned by a specific window,
+an internal helper window is used.
+
+Existing code should still work unless it depends on a specific window owning
+the clipboard.  New code may pass `NULL` as the window argument.  The parameter
+will be removed in a future release.
+
+
+@subsection removals_33 Removals in 3.3
+
+@subsubsection macos_options_33 macOS specific CMake options and macros
+
+The `GLFW_USE_RETINA`, `GLFW_USE_CHDIR` and `GLFW_USE_MENUBAR` CMake options and
+the `_GLFW_USE_RETINA`, `_GLFW_USE_CHDIR` and `_GLFW_USE_MENUBAR` compile-time
+macros have been removed.
+
+These options and macros are replaced by the window hint
+[GLFW_COCOA_RETINA_FRAMEBUFFER](@ref GLFW_COCOA_RETINA_FRAMEBUFFER_hint)
+and the init hints
+[GLFW_COCOA_CHDIR_RESOURCES](@ref GLFW_COCOA_CHDIR_RESOURCES_hint) and
+[GLFW_COCOA_MENUBAR](@ref GLFW_COCOA_MENUBAR_hint).
+
+Existing projects and makefiles that set these options or define these macros
+during compilation of GLFW will still build but it will have no effect and the
+default behaviors will be used.
+
+
+@subsubsection vulkan_sdk_33 LunarG Vulkan SDK dependency
+
+The GLFW test programs that previously depended on the LunarG Vulkan SDK now
+instead uses a Vulkan loader generated by
+[glad2](https://github.com/Dav1dde/glad).  This means the GLFW CMake files no
+longer look for the Vulkan SDK.
+
+Existing CMake projects that depended on the Vulkan SDK cache variables from
+GLFW will need to call `find_package(Vulkan)` themselves.  CMake 3.7 and later
+already comes with a
+[Vulkan find module](https://cmake.org/cmake/help/latest/module/FindVulkan.html)
+similar to the one GLFW previously included.
+
+
+@subsubsection lib_suffix_33 CMake option LIB_SUFFIX
+
+The `LIB_SUFFIX` CMake option has been removed.  GLFW now uses the
+GNUInstallDirs CMake package to handle platform specific details like the
+library directory suffix and the `LIB_SUFFIX` CMake option has been removed.
+
+Existing projects and makefiles that set the `LIB_SUFFIX` option will use the
+suffix chosen by the GNUInstallDirs package and the option will be ignored.
+
+
+@subsubsection mir_removed_33 Mir support
+
+The experimental Mir support has been completely removed as the Mir project has
+implemented support for the Wayland protocol and is recommending that
+applications use that instead.
+
+Existing projects and makefiles that select Mir when compiling GLFW will fail.
+Use Wayland or X11 instead.

+
+
+@subsubsection news_32_noapi Context-less windows
+
+GLFW now supports creating windows without a OpenGL or OpenGL ES context by
+setting the [GLFW_CLIENT_API](@ref GLFW_CLIENT_API_hint) hint to `GLFW_NO_API`.
+
+
+@subsubsection news_32_contextapi Run-time context creation API selection
+
+GLFW now supports selecting and querying the context creation API at run-time
+with the @ref GLFW_CONTEXT_CREATION_API hint and attribute.
+
+
+@subsubsection news_32_noerror Error-free context creation
+
+GLFW now supports creating and querying OpenGL and OpenGL ES contexts that do

+@section news_31 Release notes for 3.1
+
+These are the release notes for version 3.1.  For a more detailed view including
+all fixed bugs see the [version history](https://www.glfw.org/changelog.html).
+
+
+@subsection features_31 New features in version 3.1
+
+@subsubsection news_31_cursor Custom mouse cursor images
+
+GLFW now supports creating and setting both custom cursor images and standard
+cursor shapes.  They are created with @ref glfwCreateCursor or @ref
+glfwCreateStandardCursor, set with @ref glfwSetCursor and destroyed with @ref
+glfwDestroyCursor.
+
+@see @ref cursor_object
+
+
+@subsubsection news_31_drop Path drop event
+
+GLFW now provides a callback for receiving the paths of files and directories
+dropped onto GLFW windows.  The callback is set with @ref glfwSetDropCallback.
+
+@see @ref path_drop
+
+
+@subsubsection news_31_emptyevent Main thread wake-up
+
+GLFW now provides the @ref glfwPostEmptyEvent function for posting an empty
+event from another thread to the main thread event queue, causing @ref
+glfwWaitEvents to return.
+
+@see @ref events
+
+
+@subsubsection news_31_framesize Window frame size query
+
+GLFW now supports querying the size, on each side, of the frame around the
+content area of a window, with @ref glfwGetWindowFrameSize.
+
+@see [Window size](@ref window_size)
+
+
+@subsubsection news_31_autoiconify Simultaneous multi-monitor rendering
+
+GLFW now supports disabling auto-iconification of full screen windows with
+the [GLFW_AUTO_ICONIFY](@ref GLFW_AUTO_ICONIFY_hint) window hint.  This is
+intended for people building multi-monitor installations, where you need windows
+to stay in full screen despite losing input focus.
+
+
+@subsubsection news_31_floating Floating windows
+
+GLFW now supports floating windows, also called topmost or always on top, for
+easier debugging with the @ref GLFW_FLOATING window hint and attribute.
+
+
+@subsubsection news_31_focused Initially unfocused windows
+
+GLFW now supports preventing a windowed mode window from gaining input focus on
+creation, with the [GLFW_FOCUSED](@ref GLFW_FOCUSED_hint) window hint.
+
+
+@subsubsection news_31_direct Direct access for window attributes and cursor position
+
+GLFW now queries the window input focus, visibility and iconification attributes
+and the cursor position directly instead of returning cached data.
+
+
+@subsubsection news_31_charmods Character with modifiers callback
+
+GLFW now provides a callback for character events with modifier key bits.  The
+callback is set with @ref glfwSetCharModsCallback.  Unlike the regular character
+callback, this will report character events that will not result in a character
+being input, for example if the Control key is held down.
+
+@see @ref input_char
+
+
+@subsubsection news_31_single Single buffered framebuffers
+
+GLFW now supports the creation of single buffered windows, with the @ref
+GLFW_DOUBLEBUFFER hint.
+
+
+@subsubsection news_31_glext Macro for including extension header
+
+GLFW now includes the extension header appropriate for the chosen OpenGL or
+OpenGL ES header when @ref GLFW_INCLUDE_GLEXT is defined.  GLFW does not provide
+these headers.  They must be provided by your development environment or your
+OpenGL or OpenGL ES SDK.
+
+
+@subsubsection news_31_release Context release behaviors
+
+GLFW now supports controlling and querying whether the pipeline is flushed when
+a context is made non-current, with the @ref GLFW_CONTEXT_RELEASE_BEHAVIOR hint
+and attribute, provided the machine supports the `GL_KHR_context_flush_control`
+extension.
+
+
+@subsubsection news_31_wayland (Experimental) Wayland support
+
+GLFW now has an _experimental_ Wayland display protocol backend that can be
+selected on Linux with a CMake option.
+
+
+@subsubsection news_31_mir (Experimental) Mir support
+
+GLFW now has an _experimental_ Mir display server backend that can be selected
+on Linux with a CMake option.
+
+
+@section news_30 Release notes for 3.0
+
+These are the release notes for version 3.0.  For a more detailed view including
+all fixed bugs see the [version history](https://www.glfw.org/changelog.html).
+
+
+@subsection features_30 New features in version 3.0
+
+@subsubsection news_30_cmake CMake build system
+
+GLFW now uses the CMake build system instead of the various makefiles and
+project files used by earlier versions.  CMake is available for all platforms
+supported by GLFW, is present in most package systems and can generate
+makefiles and/or project files for most popular development environments.
+
+For more information on how to use CMake, see the
+[CMake manual](https://cmake.org/cmake/help/documentation.html).
+
+
+@subsubsection news_30_multiwnd Multi-window support
+
+GLFW now supports the creation of multiple windows, each with their own OpenGL
+or OpenGL ES context, and all window functions now take a window handle.  Event
+callbacks are now per-window and are provided with the handle of the window that
+received the event.  The @ref glfwMakeContextCurrent function has been added to
+select which context is current on a given thread.
+
+
+@subsubsection news_30_multimon Multi-monitor support
+
+GLFW now explicitly supports multiple monitors.  They can be enumerated with
+@ref glfwGetMonitors, queried with @ref glfwGetVideoModes, @ref
+glfwGetMonitorPos, @ref glfwGetMonitorName and @ref glfwGetMonitorPhysicalSize,
+and specified at window creation to make the newly created window full screen on
+that specific monitor.
+
+
+@subsubsection news_30_unicode Unicode support
+
+All string arguments to GLFW functions and all strings returned by GLFW now use
+the UTF-8 encoding.  This includes the window title, error string, clipboard
+text, monitor and joystick names as well as the extension function arguments (as
+ASCII is a subset of UTF-8).
+
+
+@subsubsection news_30_clipboard Clipboard text I/O
+
+GLFW now supports reading and writing plain text to and from the system
+clipboard, with the @ref glfwGetClipboardString and @ref glfwSetClipboardString
+functions.
+
+
+@subsubsection news_30_gamma Gamma ramp support
+
+GLFW now supports setting and reading back the gamma ramp of monitors, with the
+@ref glfwGetGammaRamp and @ref glfwSetGammaRamp functions.  There is also @ref
+glfwSetGamma, which generates a ramp from a gamma value and then sets it.
+
+
+@subsubsection news_30_gles OpenGL ES support
+
+GLFW now supports the creation of OpenGL ES contexts, by setting the
+[GLFW_CLIENT_API](@ref GLFW_CLIENT_API_hint) hint to `GLFW_OPENGL_ES_API`, where
+creation of such contexts are supported.  Note that GLFW _does not implement_
+OpenGL ES, so your driver must provide support in a way usable by GLFW.  Modern
+Nvidia and Intel drivers support creation of OpenGL ES context using the GLX and
+WGL APIs, while AMD provides an EGL implementation instead.
+
+
+@subsubsection news_30_egl (Experimental) EGL support
+
+GLFW now has an experimental EGL context creation back end that can be selected
+through CMake options.
+
+
+@subsubsection news_30_hidpi High-DPI support
+
+GLFW now supports high-DPI monitors on both Windows and macOS, giving windows
+full resolution framebuffers where other UI elements are scaled up.  To achieve
+this, @ref glfwGetFramebufferSize and @ref glfwSetFramebufferSizeCallback have
+been added.  These work with pixels, while the rest of the GLFW API works with
+screen coordinates.  This is important as OpenGL uses pixels, not screen
+coordinates.
+
+
+@subsubsection news_30_error Error callback
+
+GLFW now has an error callback, which can provide your application with much
+more detailed diagnostics than was previously possible.  The callback is passed
+an error code and a description string.
+
+
+@subsubsection news_30_wndptr Per-window user pointer
+
+Each window now has a user-defined pointer, retrieved with @ref
+glfwGetWindowUserPointer and set with @ref glfwSetWindowUserPointer, to make it
+easier to integrate GLFW into C++ code.
+
+
+@subsubsection news_30_iconifyfun Window iconification callback
+
+Each window now has a callback for iconification and restoration events,
+which is set with @ref glfwSetWindowIconifyCallback.
+
+
+@subsubsection news_30_wndposfun Window position callback
+
+Each window now has a callback for position events, which is set with @ref
+glfwSetWindowPosCallback.
+
+
+@subsubsection news_30_wndpos Window position query
+
+The position of a window can now be retrieved using @ref glfwGetWindowPos.
+
+
+@subsubsection news_30_focusfun Window focus callback
+
+Each windows now has a callback for focus events, which is set with @ref
+glfwSetWindowFocusCallback.
+
+
+@subsubsection news_30_enterleave Cursor enter/leave callback
+
+Each window now has a callback for when the mouse cursor enters or leaves its
+content area, which is set with @ref glfwSetCursorEnterCallback.
+
+
+@subsubsection news_30_wndtitle Initial window title
+
+The title of a window is now specified at creation time, as one of the arguments
+to @ref glfwCreateWindow.
+
+
+@subsubsection news_30_hidden Hidden windows
+
+Windows can now be hidden with @ref glfwHideWindow, shown using @ref
+glfwShowWindow and created initially hidden with the @ref GLFW_VISIBLE window
+hint and attribute.  This allows for off-screen rendering in a way compatible
+with most drivers, as well as moving a window to a specific position before
+showing it.
+
+
+@subsubsection news_30_undecorated Undecorated windows
+
+Windowed mode windows can now be created without decorations, e.g. things like
+a frame, a title bar, with the @ref GLFW_DECORATED window hint and attribute.
+This allows for the creation of things like splash screens.
+
+
+@subsubsection news_30_keymods Modifier key bit masks
+
+[Modifier key bit mask](@ref mods) parameters have been added to the
+[mouse button](@ref GLFWmousebuttonfun) and [key](@ref GLFWkeyfun) callbacks.
+
+
+@subsubsection news_30_scancode Platform-specific scancodes
+
+A scancode parameter has been added to the [key callback](@ref GLFWkeyfun). Keys
+that don't have a [key token](@ref keys) still get passed on with the key
+parameter set to `GLFW_KEY_UNKNOWN`.  These scancodes will vary between machines
+and are intended to be used for key bindings.
+
+
+@subsubsection news_30_jsname Joystick names
+
+The name of a joystick can now be retrieved using @ref glfwGetJoystickName.
+
+
+@subsubsection news_30_doxygen Doxygen documentation
+
+You are reading it.

+
+@page quick_guide Getting started
+
+@tableofcontents
+
+This guide takes you through writing a simple application using GLFW 3.  The
+application will create a window and OpenGL context, render a rotating triangle
+and exit when the user closes the window or presses _Escape_.  This guide will
+introduce a few of the most commonly used functions, but there are many more.
+
+This guide assumes no experience with earlier versions of GLFW.  If you
+have used GLFW 2 in the past, read @ref moving_guide, as some functions
+behave differently in GLFW 3.
+
+
+@section quick_steps Step by step
+
+@subsection quick_include Including the GLFW header
+
+In the source files of your application where you use OpenGL or GLFW, you need
+to include the GLFW 3 header file.
+
+@code
+#include <GLFW/glfw3.h>
+@endcode
+
+This defines all the constants, types and function prototypes of the GLFW API.
+It also includes the OpenGL header from your development environment and
+defines all the constants and types necessary for it to work on your platform
+without including any platform-specific headers.
+
+In other words:
+
+- Do _not_ include the OpenGL header yourself, as GLFW does this for you in
+  a platform-independent way
+- Do _not_ include `windows.h` or other platform-specific headers unless
+  you plan on using those APIs yourself
+- If you _do_ need to include such headers, include them _before_ the GLFW
+  header and it will detect this
+
+On some platforms supported by GLFW the OpenGL header and link library only
+expose older versions of OpenGL.  The most extreme case is Windows, which only
+exposes OpenGL 1.2.  The easiest way to work around this is to use an
+[extension loader library](@ref context_glext_auto).
+
+If you are using such a library then you should include its header _before_ the
+GLFW header.  This lets it replace the OpenGL header included by GLFW without
+conflicts.  This example uses
+[glad2](https://github.com/Dav1dde/glad), but the same rule applies to all such
+libraries.
+
+@code
+#include <glad/gl.h>
+#include <GLFW/glfw3.h>
+@endcode
+
+
+@subsection quick_init_term Initializing and terminating GLFW
+
+Before you can use most GLFW functions, the library must be initialized.  On
+successful initialization, `GLFW_TRUE` is returned.  If an error occurred,
+`GLFW_FALSE` is returned.
+
+@code
+if (!glfwInit())
+{
+    // Initialization failed
+}
+@endcode
+
+Note that `GLFW_TRUE` and `GLFW_FALSE` are and will always be one and zero.
+
+When you are done using GLFW, typically just before the application exits, you
+need to terminate GLFW.
+
+@code
+glfwTerminate();
+@endcode
+
+This destroys any remaining windows and releases any other resources allocated by
+GLFW.  After this call, you must initialize GLFW again before using any GLFW
+functions that require it.
+
+
+@subsection quick_capture_error Setting an error callback
+
+Most events are reported through callbacks, whether it's a key being pressed,
+a GLFW window being moved, or an error occurring.  Callbacks are C functions (or
+C++ static methods) that are called by GLFW with arguments describing the event.
+
+In case a GLFW function fails, an error is reported to the GLFW error callback.
+You can receive these reports with an error callback.  This function must have
+the signature below but may do anything permitted in other callbacks.
+
+@code
+void error_callback(int error, const char* description)
+{
+    fprintf(stderr, "Error: %s\n", description);
+}
+@endcode
+
+Callback functions must be set, so GLFW knows to call them.  The function to set
+the error callback is one of the few GLFW functions that may be called before
+initialization, which lets you be notified of errors both during and after
+initialization.
+
+@code
+glfwSetErrorCallback(error_callback);
+@endcode
+
+
+@subsection quick_create_window Creating a window and context
+
+The window and its OpenGL context are created with a single call to @ref
+glfwCreateWindow, which returns a handle to the created combined window and
+context object
+
+@code
+GLFWwindow* window = glfwCreateWindow(640, 480, "My Title", NULL, NULL);
+if (!window)
+{
+    // Window or OpenGL context creation failed
+}
+@endcode
+
+This creates a 640 by 480 windowed mode window with an OpenGL context.  If
+window or OpenGL context creation fails, `NULL` will be returned.  You should
+always check the return value.  While window creation rarely fails, context
+creation depends on properly installed drivers and may fail even on machines
+with the necessary hardware.
+
+By default, the OpenGL context GLFW creates may have any version.  You can
+require a minimum OpenGL version by setting the `GLFW_CONTEXT_VERSION_MAJOR` and
+`GLFW_CONTEXT_VERSION_MINOR` hints _before_ creation.  If the required minimum
+version is not supported on the machine, context (and window) creation fails.
+
+@code
+glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 2);
+glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 0);
+GLFWwindow* window = glfwCreateWindow(640, 480, "My Title", NULL, NULL);
+if (!window)
+{
+    // Window or context creation failed
+}
+@endcode
+
+The window handle is passed to all window related functions and is provided to
+along to all window related callbacks, so they can tell which window received
+the event.
+
+When a window and context is no longer needed, destroy it.
+
+@code
+glfwDestroyWindow(window);
+@endcode
+
+Once this function is called, no more events will be delivered for that window
+and its handle becomes invalid.
+
+
+@subsection quick_context_current Making the OpenGL context current
+
+Before you can use the OpenGL API, you must have a current OpenGL context.
+
+@code
+glfwMakeContextCurrent(window);
+@endcode
+
+The context will remain current until you make another context current or until
+the window owning the current context is destroyed.
+
+If you are using an [extension loader library](@ref context_glext_auto) to
+access modern OpenGL then this is when to initialize it, as the loader needs
+a current context to load from.  This example uses
+[glad](https://github.com/Dav1dde/glad), but the same rule applies to all such
+libraries.
+
+@code
+gladLoadGL(glfwGetProcAddress);
+@endcode
+
+
+@subsection quick_window_close Checking the window close flag
+
+Each window has a flag indicating whether the window should be closed.
+
+When the user attempts to close the window, either by pressing the close widget
+in the title bar or using a key combination like Alt+F4, this flag is set to 1.
+Note that __the window isn't actually closed__, so you are expected to monitor
+this flag and either destroy the window or give some kind of feedback to the
+user.
+
+@code
+while (!glfwWindowShouldClose(window))
+{
+    // Keep running
+}
+@endcode
+
+You can be notified when the user is attempting to close the window by setting
+a close callback with @ref glfwSetWindowCloseCallback.  The callback will be
+called immediately after the close flag has been set.
+
+You can also set it yourself with @ref glfwSetWindowShouldClose.  This can be
+useful if you want to interpret other kinds of input as closing the window, like
+for example pressing the _Escape_ key.
+
+
+@subsection quick_key_input Receiving input events
+
+Each window has a large number of callbacks that can be set to receive all the
+various kinds of events.  To receive key press and release events, create a key
+callback function.
+
+@code
+static void key_callback(GLFWwindow* window, int key, int scancode, int action, int mods)
+{
+    if (key == GLFW_KEY_ESCAPE && action == GLFW_PRESS)
+        glfwSetWindowShouldClose(window, GLFW_TRUE);
+}
+@endcode
+
+The key callback, like other window related callbacks, are set per-window.
+
+@code
+glfwSetKeyCallback(window, key_callback);
+@endcode
+
+In order for event callbacks to be called when events occur, you need to process
+events as described below.
+
+
+@subsection quick_render Rendering with OpenGL
+
+Once you have a current OpenGL context, you can use OpenGL normally.  In this
+tutorial, a multi-colored rotating triangle will be rendered.  The framebuffer
+size needs to be retrieved for `glViewport`.
+
+@code
+int width, height;
+glfwGetFramebufferSize(window, &width, &height);
+glViewport(0, 0, width, height);
+@endcode
+
+You can also set a framebuffer size callback using @ref
+glfwSetFramebufferSizeCallback and be notified when the size changes.
+
+Actual rendering with OpenGL is outside the scope of this tutorial, but there
+are [many](https://open.gl/) [excellent](https://learnopengl.com/)
+[tutorial](http://openglbook.com/) [sites](http://ogldev.atspace.co.uk/) that
+teach modern OpenGL.  Some of them use GLFW to create the context and window
+while others use GLUT or SDL, but remember that OpenGL itself always works the
+same.
+
+
+@subsection quick_timer Reading the timer
+
+To create smooth animation, a time source is needed.  GLFW provides a timer that
+returns the number of seconds since initialization.  The time source used is the
+most accurate on each platform and generally has micro- or nanosecond
+resolution.
+
+@code
+double time = glfwGetTime();
+@endcode
+
+
+@subsection quick_swap_buffers Swapping buffers
+
+GLFW windows by default use double buffering.  That means that each window has
+two rendering buffers; a front buffer and a back buffer.  The front buffer is
+the one being displayed and the back buffer the one you render to.
+
+When the entire frame has been rendered, the buffers need to be swapped with one
+another, so the back buffer becomes the front buffer and vice versa.
+
+@code
+glfwSwapBuffers(window);
+@endcode
+
+The swap interval indicates how many frames to wait until swapping the buffers,
+commonly known as _vsync_.  By default, the swap interval is zero, meaning
+buffer swapping will occur immediately.  On fast machines, many of those frames
+will never be seen, as the screen is still only updated typically 60-75 times
+per second, so this wastes a lot of CPU and GPU cycles.
+
+Also, because the buffers will be swapped in the middle the screen update,
+leading to [screen tearing](https://en.wikipedia.org/wiki/Screen_tearing).
+
+For these reasons, applications will typically want to set the swap interval to
+one.  It can be set to higher values, but this is usually not recommended,
+because of the input latency it leads to.
+
+@code
+glfwSwapInterval(1);
+@endcode
+
+This function acts on the current context and will fail unless a context is
+current.
+
+
+@subsection quick_process_events Processing events
+
+GLFW needs to communicate regularly with the window system both in order to
+receive events and to show that the application hasn't locked up.  Event
+processing must be done regularly while you have visible windows and is normally
+done each frame after buffer swapping.
+
+There are two methods for processing pending events; polling and waiting.  This
+example will use event polling, which processes only those events that have
+already been received and then returns immediately.
+
+@code
+glfwPollEvents();
+@endcode
+
+This is the best choice when rendering continually, like most games do.  If
+instead you only need to update your rendering once you have received new input,
+@ref glfwWaitEvents is a better choice.  It waits until at least one event has
+been received, putting the thread to sleep in the meantime, and then processes
+all received events.  This saves a great deal of CPU cycles and is useful for,
+for example, many kinds of editing tools.
+
+
+@section quick_example Putting it together
+
+Now that you know how to initialize GLFW, create a window and poll for
+keyboard input, it's possible to create a simple program.
+
+This program creates a 640 by 480 windowed mode window and starts a loop that
+clears the screen, renders a triangle and processes events until the user either
+presses _Escape_ or closes the window.
+
+@snippet simple.c code
+
+The program above can be found in the
+[source package](https://www.glfw.org/download.html) as `examples/simple.c`
+and is compiled along with all other examples when you build GLFW.  If you
+built GLFW from the source package then you already have this as `simple.exe` on
+Windows, `simple` on Linux or `simple.app` on macOS.
+
+This tutorial used only a few of the many functions GLFW provides.  There are
+guides for each of the areas covered by GLFW.  Each guide will introduce all the
+functions for that category.
+
+ - @ref intro_guide
+ - @ref window_guide
+ - @ref context_guide
+ - @ref monitor_guide
+ - @ref input_guide
+
+You can access reference documentation for any GLFW function by clicking it and
+the reference for each function links to related functions and guide sections.
+
+The tutorial ends here.  Once you have written a program that uses GLFW, you
+will need to compile and link it.  How to do that depends on the development
+environment you are using and is best explained by the documentation for that
+environment.  To learn about the details that are specific to GLFW, see
+@ref build_guide.

+@page vulkan_guide Vulkan guide
+
+@tableofcontents
+
+This guide is intended to fill the gaps between the [Vulkan
+documentation](https://www.khronos.org/vulkan/) and the rest of the GLFW
+documentation and is not a replacement for either.  It assumes some familiarity
+with Vulkan concepts like loaders, devices, queues and surfaces and leaves it to
+the Vulkan documentation to explain the details of Vulkan functions.
+
+To develop for Vulkan you should download the [LunarG Vulkan
+SDK](https://vulkan.lunarg.com/) for your platform.  Apart from headers and link
+libraries, they also provide the validation layers necessary for development.
+
+For details on a specific function in this category, see the @ref vulkan.  There
+are also guides for the other areas of the GLFW API.
+
+ - @ref intro_guide
+ - @ref window_guide
+ - @ref context_guide
+ - @ref monitor_guide
+ - @ref input_guide
+
+
+@section vulkan_loader Linking against the Vulkan loader
+
+By default, GLFW will look for the Vulkan loader on demand at runtime via its
+standard name (`vulkan-1.dll` on Windows, `libvulkan.so.1` on Linux and other
+Unix-like systems and `libvulkan.1.dylib` on macOS).  This means that GLFW does
+not need to be linked against the loader.  However, it also means that if you
+are using the static library form of the Vulkan loader GLFW will either fail to
+find it or (worse) use the wrong one.
+
+The @ref GLFW_VULKAN_STATIC CMake option makes GLFW call the Vulkan loader
+directly instead of dynamically loading it at runtime.  Not linking against the
+Vulkan loader will then be a compile-time error.
+
+@macos Because the Vulkan loader and ICD are not installed globally on macOS,
+you need to set up the application bundle according to the LunarG SDK
+documentation.  This is explained in more detail in the
+[SDK documentation for macOS](https://vulkan.lunarg.com/doc/sdk/latest/mac/getting_started.html).
+
+
+@section vulkan_include Including the Vulkan and GLFW header files
+
+To include the Vulkan header, define @ref GLFW_INCLUDE_VULKAN before including
+the GLFW header.
+
+@code
+#define GLFW_INCLUDE_VULKAN
+#include <GLFW/glfw3.h>
+@endcode
+
+If you instead want to include the Vulkan header from a custom location or use
+your own custom Vulkan header then do this before the GLFW header.
+
+@code
+#include <path/to/vulkan.h>
+#include <GLFW/glfw3.h>
+@endcode
+
+Unless a Vulkan header is included, either by the GLFW header or above it, any
+GLFW functions that take or return Vulkan types will not be declared.
+
+The `VK_USE_PLATFORM_*_KHR` macros do not need to be defined for the Vulkan part
+of GLFW to work.  Define them only if you are using these extensions directly.
+
+
+@section vulkan_support Querying for Vulkan support
+
+If you are linking directly against the Vulkan loader then you can skip this
+section.  The canonical desktop loader library exports all Vulkan core and
+Khronos extension functions, allowing them to be called directly.
+
+If you are loading the Vulkan loader dynamically instead of linking directly
+against it, you can check for the availability of a loader and ICD with @ref
+glfwVulkanSupported.
+
+@code
+if (glfwVulkanSupported())
+{
+    // Vulkan is available, at least for compute
+}
+@endcode
+
+This function returns `GLFW_TRUE` if the Vulkan loader and any minimally
+functional ICD was found.
+
+If if one or both were not found, calling any other Vulkan related GLFW function
+will generate a @ref GLFW_API_UNAVAILABLE error.
+
+
+@subsection vulkan_proc Querying Vulkan function pointers
+
+To load any Vulkan core or extension function from the found loader, call @ref
+glfwGetInstanceProcAddress.  To load functions needed for instance creation,
+pass `NULL` as the instance.
+
+@code
+PFN_vkCreateInstance pfnCreateInstance = (PFN_vkCreateInstance)
+    glfwGetInstanceProcAddress(NULL, "vkCreateInstance");
+@endcode
+
+Once you have created an instance, you can load from it all other Vulkan core
+functions and functions from any instance extensions you enabled.
+
+@code
+PFN_vkCreateDevice pfnCreateDevice = (PFN_vkCreateDevice)
+    glfwGetInstanceProcAddress(instance, "vkCreateDevice");
+@endcode
+
+This function in turn calls `vkGetInstanceProcAddr`.  If that fails, the
+function falls back to a platform-specific query of the Vulkan loader (i.e.
+`dlsym` or `GetProcAddress`).  If that also fails, the function returns `NULL`.
+For more information about `vkGetInstanceProcAddr`, see the Vulkan
+documentation.
+
+Vulkan also provides `vkGetDeviceProcAddr` for loading device-specific versions
+of Vulkan function.  This function can be retrieved from an instance with @ref
+glfwGetInstanceProcAddress.
+
+@code
+PFN_vkGetDeviceProcAddr pfnGetDeviceProcAddr = (PFN_vkGetDeviceProcAddr)
+    glfwGetInstanceProcAddress(instance, "vkGetDeviceProcAddr");
+@endcode
+
+Device-specific functions may execute a little bit faster, due to not having to
+dispatch internally based on the device passed to them.  For more information
+about `vkGetDeviceProcAddr`, see the Vulkan documentation.
+
+
+@section vulkan_ext Querying required Vulkan extensions
+
+To do anything useful with Vulkan you need to create an instance.  If you want
+to use Vulkan to render to a window, you must enable the instance extensions
+GLFW requires to create Vulkan surfaces.
+
+To query the instance extensions required, call @ref
+glfwGetRequiredInstanceExtensions.
+
+@code
+uint32_t count;
+const char** extensions = glfwGetRequiredInstanceExtensions(&count);
+@endcode
+
+These extensions must all be enabled when creating instances that are going to
+be passed to @ref glfwGetPhysicalDevicePresentationSupport and @ref
+glfwCreateWindowSurface.  The set of extensions will vary depending on platform
+and may also vary depending on graphics drivers and other factors.
+
+If it fails it will return `NULL` and GLFW will not be able to create Vulkan
+window surfaces.  You can still use Vulkan for off-screen rendering and compute
+work.
+
+If successful the returned array will always include `VK_KHR_surface`, so if
+you don't require any additional extensions you can pass this list directly to
+the `VkInstanceCreateInfo` struct.
+
+@code
+VkInstanceCreateInfo ici;
+
+memset(&ici, 0, sizeof(ici));
+ici.enabledExtensionCount = count;
+ici.ppEnabledExtensionNames = extensions;
+...
+@endcode
+
+Additional extensions may be required by future versions of GLFW.  You should
+check whether any extensions you wish to enable are already in the returned
+array, as it is an error to specify an extension more than once in the
+`VkInstanceCreateInfo` struct.
+
+
+@section vulkan_present Querying for Vulkan presentation support
+
+Not every queue family of every Vulkan device can present images to surfaces.
+To check whether a specific queue family of a physical device supports image
+presentation without first having to create a window and surface, call @ref
+glfwGetPhysicalDevicePresentationSupport.
+
+@code
+if (glfwGetPhysicalDevicePresentationSupport(instance, physical_device, queue_family_index))
+{
+    // Queue family supports image presentation
+}
+@endcode
+
+The `VK_KHR_surface` extension additionally provides the
+`vkGetPhysicalDeviceSurfaceSupportKHR` function, which performs the same test on
+an existing Vulkan surface.
+
+
+@section vulkan_window Creating the window
+
+Unless you will be using OpenGL or OpenGL ES with the same window as Vulkan,
+there is no need to create a context.  You can disable context creation with the
+[GLFW_CLIENT_API](@ref GLFW_CLIENT_API_hint) hint.
+
+@code
+glfwWindowHint(GLFW_CLIENT_API, GLFW_NO_API);
+GLFWwindow* window = glfwCreateWindow(640, 480, "Window Title", NULL, NULL);
+@endcode
+
+See @ref context_less for more information.
+
+
+@section vulkan_surface Creating a Vulkan window surface
+
+You can create a Vulkan surface (as defined by the `VK_KHR_surface` extension)
+for a GLFW window with @ref glfwCreateWindowSurface.
+
+@code
+VkSurfaceKHR surface;
+VkResult err = glfwCreateWindowSurface(instance, window, NULL, &surface);
+if (err)
+{
+    // Window surface creation failed
+}
+@endcode
+
+If an OpenGL or OpenGL ES context was created on the window, the context has
+ownership of the presentation on the window and a Vulkan surface cannot be
+created.
+
+It is your responsibility to destroy the surface.  GLFW does not destroy it for
+you.  Call `vkDestroySurfaceKHR` function from the same extension to destroy it.

+
+@page window_guide Window guide
+
+@tableofcontents
+
+This guide introduces the window related functions of GLFW.  For details on
+a specific function in this category, see the @ref window.  There are also
+guides for the other areas of GLFW.
+
+ - @ref intro_guide
+ - @ref context_guide
+ - @ref vulkan_guide
+ - @ref monitor_guide
+ - @ref input_guide
+
+
+@section window_object Window objects
+
+The @ref GLFWwindow object encapsulates both a window and a context.  They are
+created with @ref glfwCreateWindow and destroyed with @ref glfwDestroyWindow, or
+@ref glfwTerminate, if any remain.  As the window and context are inseparably
+linked, the object pointer is used as both a context and window handle.
+
+To see the event stream provided to the various window related callbacks, run
+the `events` test program.
+
+
+@subsection window_creation Window creation
+
+A window and its OpenGL or OpenGL ES context are created with @ref
+glfwCreateWindow, which returns a handle to the created window object.  For
+example, this creates a 640 by 480 windowed mode window:
+
+@code
+GLFWwindow* window = glfwCreateWindow(640, 480, "My Title", NULL, NULL);
+@endcode
+
+If window creation fails, `NULL` will be returned, so it is necessary to check
+the return value.
+
+The window handle is passed to all window related functions and is provided to
+along with all input events, so event handlers can tell which window received
+the event.
+
+
+@subsubsection window_full_screen Full screen windows
+
+To create a full screen window, you need to specify which monitor the window
+should use.  In most cases, the user's primary monitor is a good choice.
+For more information about retrieving monitors, see @ref monitor_monitors.
+
+@code
+GLFWwindow* window = glfwCreateWindow(640, 480, "My Title", glfwGetPrimaryMonitor(), NULL);
+@endcode
+
+Full screen windows cover the entire display area of a monitor, have no border
+or decorations.
+
+Windowed mode windows can be made full screen by setting a monitor with @ref
+glfwSetWindowMonitor, and full screen ones can be made windowed by unsetting it
+with the same function.
+
+Each field of the @ref GLFWvidmode structure corresponds to a function parameter
+or window hint and combine to form the _desired video mode_ for that window.
+The supported video mode most closely matching the desired video mode will be
+set for the chosen monitor as long as the window has input focus.  For more
+information about retrieving video modes, see @ref monitor_modes.
+
+Video mode field        | Corresponds to
+----------------        | --------------
+GLFWvidmode.width       | `width` parameter of @ref glfwCreateWindow
+GLFWvidmode.height      | `height` parameter of @ref glfwCreateWindow
+GLFWvidmode.redBits     | @ref GLFW_RED_BITS hint
+GLFWvidmode.greenBits   | @ref GLFW_GREEN_BITS hint
+GLFWvidmode.blueBits    | @ref GLFW_BLUE_BITS hint
+GLFWvidmode.refreshRate | @ref GLFW_REFRESH_RATE hint
+
+Once you have a full screen window, you can change its resolution, refresh rate
+and monitor with @ref glfwSetWindowMonitor.  If you only need change its
+resolution you can also call @ref glfwSetWindowSize.  In all cases, the new
+video mode will be selected the same way as the video mode chosen by @ref
+glfwCreateWindow.  If the window has an OpenGL or OpenGL ES context, it will be
+unaffected.
+
+By default, the original video mode of the monitor will be restored and the
+window iconified if it loses input focus, to allow the user to switch back to
+the desktop.  This behavior can be disabled with the
+[GLFW_AUTO_ICONIFY](@ref GLFW_AUTO_ICONIFY_hint) window hint, for example if you
+wish to simultaneously cover multiple monitors with full screen windows.
+
+If a monitor is disconnected, all windows that are full screen on that monitor
+will be switched to windowed mode.  See @ref monitor_event for more information.
+
+
+@subsubsection window_windowed_full_screen "Windowed full screen" windows
+
+If the closest match for the desired video mode is the current one, the video
+mode will not be changed, making window creation faster and application
+switching much smoother.  This is sometimes called _windowed full screen_ or
+_borderless full screen_ window and counts as a full screen window.  To create
+such a window, request the current video mode.
+
+@code
+const GLFWvidmode* mode = glfwGetVideoMode(monitor);
+
+glfwWindowHint(GLFW_RED_BITS, mode->redBits);
+glfwWindowHint(GLFW_GREEN_BITS, mode->greenBits);
+glfwWindowHint(GLFW_BLUE_BITS, mode->blueBits);
+glfwWindowHint(GLFW_REFRESH_RATE, mode->refreshRate);
+
+GLFWwindow* window = glfwCreateWindow(mode->width, mode->height, "My Title", monitor, NULL);
+@endcode
+
+This also works for windowed mode windows that are made full screen.
+
+@code
+const GLFWvidmode* mode = glfwGetVideoMode(monitor);
+
+glfwSetWindowMonitor(window, monitor, 0, 0, mode->width, mode->height, mode->refreshRate);
+@endcode
+
+Note that @ref glfwGetVideoMode returns the _current_ video mode of a monitor,
+so if you already have a full screen window on that monitor that you want to
+make windowed full screen, you need to have saved the desktop resolution before.
+
+
+@subsection window_destruction Window destruction
+
+When a window is no longer needed, destroy it with @ref glfwDestroyWindow.
+
+@code
+glfwDestroyWindow(window);
+@endcode
+
+Window destruction always succeeds.  Before the actual destruction, all
+callbacks are removed so no further events will be delivered for the window.
+All windows remaining when @ref glfwTerminate is called are destroyed as well.
+
+When a full screen window is destroyed, the original video mode of its monitor
+is restored, but the gamma ramp is left untouched.
+
+
+@subsection window_hints Window creation hints
+
+There are a number of hints that can be set before the creation of a window and
+context.  Some affect the window itself, others affect the framebuffer or
+context.  These hints are set to their default values each time the library is
+initialized with @ref glfwInit.  Integer value hints can be set individually
+with @ref glfwWindowHint and string value hints with @ref glfwWindowHintString.
+You can reset all at once to their defaults with @ref glfwDefaultWindowHints.
+
+Some hints are platform specific.  These are always valid to set on any
+platform but they will only affect their specific platform.  Other platforms
+will ignore them.  Setting these hints requires no platform specific headers or
+calls.
+
+@note Window hints need to be set before the creation of the window and context
+you wish to have the specified attributes.  They function as additional
+arguments to @ref glfwCreateWindow.
+
+
+@subsubsection window_hints_hard Hard and soft constraints
+
+Some window hints are hard constraints.  These must match the available
+capabilities _exactly_ for window and context creation to succeed.  Hints
+that are not hard constraints are matched as closely as possible, but the
+resulting context and framebuffer may differ from what these hints requested.
+
+The following hints are always hard constraints:
+- @ref GLFW_STEREO
+- @ref GLFW_DOUBLEBUFFER
+- [GLFW_CLIENT_API](@ref GLFW_CLIENT_API_hint)
+- [GLFW_CONTEXT_CREATION_API](@ref GLFW_CONTEXT_CREATION_API_hint)
+
+The following additional hints are hard constraints when requesting an OpenGL

+
+@anchor GLFW_RESIZABLE_hint
+__GLFW_RESIZABLE__ specifies whether the windowed mode window will be resizable
+_by the user_.  The window will still be resizable using the @ref
+glfwSetWindowSize function.  Possible values are `GLFW_TRUE` and `GLFW_FALSE`.
+This hint is ignored for full screen and undecorated windows.
+
+@anchor GLFW_VISIBLE_hint
+__GLFW_VISIBLE__ specifies whether the windowed mode window will be initially
+visible.  Possible values are `GLFW_TRUE` and `GLFW_FALSE`.  This hint is
+ignored for full screen windows.
+
+@anchor GLFW_DECORATED_hint
+__GLFW_DECORATED__ specifies whether the windowed mode window will have window
+decorations such as a border, a close widget, etc.  An undecorated window will
+not be resizable by the user but will still allow the user to generate close
+events on some platforms.  Possible values are `GLFW_TRUE` and `GLFW_FALSE`.
+This hint is ignored for full screen windows.
+
+@anchor GLFW_FOCUSED_hint
+__GLFW_FOCUSED__ specifies whether the windowed mode window will be given input
+focus when created.  Possible values are `GLFW_TRUE` and `GLFW_FALSE`.  This
+hint is ignored for full screen and initially hidden windows.
+
+@anchor GLFW_AUTO_ICONIFY_hint
+__GLFW_AUTO_ICONIFY__ specifies whether the full screen window will
+automatically iconify and restore the previous video mode on input focus loss.
+Possible values are `GLFW_TRUE` and `GLFW_FALSE`.  This hint is ignored for
+windowed mode windows.
+
+@anchor GLFW_FLOATING_hint
+__GLFW_FLOATING__ specifies whether the windowed mode window will be floating
+above other regular windows, also called topmost or always-on-top.  This is
+intended primarily for debugging purposes and cannot be used to implement proper
+full screen windows.  Possible values are `GLFW_TRUE` and `GLFW_FALSE`.  This
+hint is ignored for full screen windows.
+
+@anchor GLFW_MAXIMIZED_hint
+__GLFW_MAXIMIZED__ specifies whether the windowed mode window will be maximized
+when created.  Possible values are `GLFW_TRUE` and `GLFW_FALSE`.  This hint is
+ignored for full screen windows.
+
+@anchor GLFW_CENTER_CURSOR_hint
+__GLFW_CENTER_CURSOR__ specifies whether the cursor should be centered over
+newly created full screen windows.  Possible values are `GLFW_TRUE` and
+`GLFW_FALSE`.  This hint is ignored for windowed mode windows.
+
+@anchor GLFW_TRANSPARENT_FRAMEBUFFER_hint
+__GLFW_TRANSPARENT_FRAMEBUFFER__ specifies whether the window framebuffer will
+be transparent.  If enabled and supported by the system, the window framebuffer
+alpha channel will be used to combine the framebuffer with the background.  This
+does not affect window decorations.  Possible values are `GLFW_TRUE` and
+`GLFW_FALSE`.
+
+@par
+@win32 GLFW sets a color key for the window to work around repainting issues
+with a transparent framebuffer.  The chosen color value is RGB 255,0,255
+(magenta).  This will make pixels with that exact color fully transparent
+regardless of their alpha values.  If this is a problem, make these pixels any
+other color before buffer swap.
+
+@anchor GLFW_FOCUS_ON_SHOW_hint
+__GLFW_FOCUS_ON_SHOW__ specifies whether the window will be given input
+focus when @ref glfwShowWindow is called. Possible values are `GLFW_TRUE` and `GLFW_FALSE`.
+
+@anchor GLFW_SCALE_TO_MONITOR
+__GLFW_SCALE_TO_MONITOR__ specified whether the window content area should be
+resized based on the [monitor content scale](@ref monitor_scale) of any monitor
+it is placed on.  This includes the initial placement when the window is
+created.  Possible values are `GLFW_TRUE` and `GLFW_FALSE`.
+
+This hint only has an effect on platforms where screen coordinates and pixels
+always map 1:1 such as Windows and X11.  On platforms like macOS the resolution
+of the framebuffer is changed independently of the window size.

+
+@note An OpenGL extension loader library that assumes it knows which context

+`GLFW_VERSION_MINOR`, which provide the API version of the GLFW header.
+
+@par
+__OpenGL:__ These hints are not hard constraints, but creation will fail if the
+OpenGL version of the created context is less than the one requested.  It is
+therefore perfectly safe to use the default of version 1.0 for legacy code and

+available.
+
+@par
+While there is no way to ask the driver for a context of the highest supported
+version, GLFW will attempt to provide this when you ask for a version 1.0
+context, which is the default for these hints.
+
+@par
+__OpenGL ES:__ These hints are not hard constraints, but creation will fail if
+the OpenGL ES version of the created context is less than the one requested.
+Additionally, OpenGL ES 1.x cannot be returned if 2.0 or later was requested,
+and vice versa.  This is because OpenGL ES 3.x is backward compatible with 2.0,
+but OpenGL ES 2.0 is not backward compatible with 1.x.
+
+@note @macos The OS only supports forward-compatible core profile contexts for

+@section window_events Window event processing
+
+See @ref events.
+
+
+@section window_properties Window properties and events
+
+@subsection window_userptr User pointer
+
+Each window has a user pointer that can be set with @ref
+glfwSetWindowUserPointer and queried with @ref glfwGetWindowUserPointer.  This
+can be used for any purpose you need and will not be modified by GLFW throughout
+the life-time of the window.
+
+The initial value of the pointer is `NULL`.
+
+
+@subsection window_close Window closing and close flag
+
+When the user attempts to close the window, for example by clicking the close
+widget or using a key chord like Alt+F4, the _close flag_ of the window is set.
+The window is however not actually destroyed and, unless you watch for this
+state change, nothing further happens.
+
+The current state of the close flag is returned by @ref glfwWindowShouldClose
+and can be set or cleared directly with @ref glfwSetWindowShouldClose.  A common
+pattern is to use the close flag as a main loop condition.
+
+@code
+while (!glfwWindowShouldClose(window))
+{
+    render(window);
+
+    glfwSwapBuffers(window);
+    glfwPollEvents();
+}
+@endcode
+
+If you wish to be notified when the user attempts to close a window, set a close
+callback.
+
+@code
+glfwSetWindowCloseCallback(window, window_close_callback);
+@endcode
+
+The callback function is called directly _after_ the close flag has been set.
+It can be used for example to filter close requests and clear the close flag
+again unless certain conditions are met.
+
+@code
+void window_close_callback(GLFWwindow* window)
+{
+    if (!time_to_close)
+        glfwSetWindowShouldClose(window, GLFW_FALSE);
+}
+@endcode
+
+
+@subsection window_size Window size
+
+The size of a window can be changed with @ref glfwSetWindowSize.  For windowed
+mode windows, this sets the size, in
+[screen coordinates](@ref coordinate_systems) of the _content area_ or _content
+area_ of the window.  The window system may impose limits on window size.
+
+@code
+glfwSetWindowSize(window, 640, 480);
+@endcode
+
+For full screen windows, the specified size becomes the new resolution of the
+window's desired video mode.  The video mode most closely matching the new
+desired video mode is set immediately.  The window is resized to fit the
+resolution of the set video mode.
+
+If you wish to be notified when a window is resized, whether by the user, the
+system or your own code, set a size callback.
+
+@code
+glfwSetWindowSizeCallback(window, window_size_callback);
+@endcode
+
+The callback function receives the new size, in screen coordinates, of the
+content area of the window when the window is resized.
+
+@code
+void window_size_callback(GLFWwindow* window, int width, int height)
+{
+}
+@endcode
+
+There is also @ref glfwGetWindowSize for directly retrieving the current size of
+a window.
+
+@code
+int width, height;
+glfwGetWindowSize(window, &width, &height);
+@endcode
+
+@note Do not pass the window size to `glViewport` or other pixel-based OpenGL
+calls.  The window size is in screen coordinates, not pixels.  Use the
+[framebuffer size](@ref window_fbsize), which is in pixels, for pixel-based
+calls.
+
+The above functions work with the size of the content area, but decorated
+windows typically have title bars and window frames around this rectangle.  You
+can retrieve the extents of these with @ref glfwGetWindowFrameSize.
+
+@code
+int left, top, right, bottom;
+glfwGetWindowFrameSize(window, &left, &top, &right, &bottom);
+@endcode
+
+The returned values are the distances, in screen coordinates, from the edges of
+the content area to the corresponding edges of the full window.  As they are
+distances and not coordinates, they are always zero or positive.
+
+
+@subsection window_fbsize Framebuffer size
+
+While the size of a window is measured in screen coordinates, OpenGL works with
+pixels.  The size you pass into `glViewport`, for example, should be in pixels.
+On some machines screen coordinates and pixels are the same, but on others they
+will not be.  There is a second set of functions to retrieve the size, in
+pixels, of the framebuffer of a window.
+
+If you wish to be notified when the framebuffer of a window is resized, whether
+by the user or the system, set a size callback.
+
+@code
+glfwSetFramebufferSizeCallback(window, framebuffer_size_callback);
+@endcode
+
+The callback function receives the new size of the framebuffer when it is
+resized, which can for example be used to update the OpenGL viewport.
+
+@code
+void framebuffer_size_callback(GLFWwindow* window, int width, int height)
+{
+    glViewport(0, 0, width, height);
+}
+@endcode
+
+There is also @ref glfwGetFramebufferSize for directly retrieving the current
+size of the framebuffer of a window.
+
+@code
+int width, height;
+glfwGetFramebufferSize(window, &width, &height);
+glViewport(0, 0, width, height);
+@endcode
+
+The size of a framebuffer may change independently of the size of a window, for
+example if the window is dragged between a regular monitor and a high-DPI one.
+
+
+@subsection window_scale Window content scale
+
+The content scale for a window can be retrieved with @ref
+glfwGetWindowContentScale.
+
+@code
+float xscale, yscale;
+glfwGetWindowContentScale(window, &xscale, &yscale);
+@endcode
+
+The content scale is the ratio between the current DPI and the platform's
+default DPI.  This is especially important for text and any UI elements.  If the
+pixel dimensions of your UI scaled by this look appropriate on your machine then
+it should appear at a reasonable size on other machines regardless of their DPI
+and scaling settings.  This relies on the system DPI and scaling settings being
+somewhat correct.
+
+On systems where each monitors can have its own content scale, the window
+content scale will depend on which monitor the system considers the window to be
+on.
+
+If you wish to be notified when the content scale of a window changes, whether
+because of a system setting change or because it was moved to a monitor with
+a different scale, set a content scale callback.
+
+@code
+glfwSetWindowContentScaleCallback(window, window_content_scale_callback);
+@endcode
+
+The callback function receives the new content scale of the window.
+
+@code
+void window_content_scale_callback(GLFWwindow* window, float xscale, float yscale)
+{
+    set_interface_scale(xscale, yscale);
+}
+@endcode
+
+On platforms where pixels and screen coordinates always map 1:1, the window
+will need to be resized to appear the same size when it is moved to a monitor
+with a different content scale.  To have this done automatically both when the
+window is created and when its content scale later changes, set the @ref
+GLFW_SCALE_TO_MONITOR window hint.
+
+
+@subsection window_sizelimits Window size limits
+
+The minimum and maximum size of the content area of a windowed mode window can
+be enforced with @ref glfwSetWindowSizeLimits.  The user may resize the window
+to any size and aspect ratio within the specified limits, unless the aspect
+ratio is also set.
+
+@code
+glfwSetWindowSizeLimits(window, 200, 200, 400, 400);
+@endcode
+
+To specify only a minimum size or only a maximum one, set the other pair to
+`GLFW_DONT_CARE`.
+
+@code
+glfwSetWindowSizeLimits(window, 640, 480, GLFW_DONT_CARE, GLFW_DONT_CARE);
+@endcode
+
+To disable size limits for a window, set them all to `GLFW_DONT_CARE`.
+
+The aspect ratio of the content area of a windowed mode window can be enforced
+with @ref glfwSetWindowAspectRatio.  The user may resize the window freely
+unless size limits are also set, but the size will be constrained to maintain
+the aspect ratio.
+
+@code
+glfwSetWindowAspectRatio(window, 16, 9);
+@endcode
+
+The aspect ratio is specified as a numerator and denominator, corresponding to
+the width and height, respectively.  If you want a window to maintain its
+current aspect ratio, use its current size as the ratio.
+
+@code
+int width, height;
+glfwGetWindowSize(window, &width, &height);
+glfwSetWindowAspectRatio(window, width, height);
+@endcode
+
+To disable the aspect ratio limit for a window, set both terms to
+`GLFW_DONT_CARE`.
+
+You can have both size limits and aspect ratio set for a window, but the results
+are undefined if they conflict.
+
+
+@subsection window_pos Window position
+
+The position of a windowed-mode window can be changed with @ref
+glfwSetWindowPos.  This moves the window so that the upper-left corner of its
+content area has the specified [screen coordinates](@ref coordinate_systems).
+The window system may put limitations on window placement.
+
+@code
+glfwSetWindowPos(window, 100, 100);
+@endcode
+
+If you wish to be notified when a window is moved, whether by the user, the
+system or your own code, set a position callback.
+
+@code
+glfwSetWindowPosCallback(window, window_pos_callback);
+@endcode
+
+The callback function receives the new position, in screen coordinates, of the
+upper-left corner of the content area when the window is moved.
+
+@code
+void window_pos_callback(GLFWwindow* window, int xpos, int ypos)
+{
+}
+@endcode
+
+There is also @ref glfwGetWindowPos for directly retrieving the current position
+of the content area of the window.
+
+@code
+int xpos, ypos;
+glfwGetWindowPos(window, &xpos, &ypos);
+@endcode
+
+
+@subsection window_title Window title
+
+All GLFW windows have a title, although undecorated or full screen windows may
+not display it or only display it in a task bar or similar interface.  You can
+set a UTF-8 encoded window title with @ref glfwSetWindowTitle.
+
+@code
+glfwSetWindowTitle(window, "My Window");
+@endcode
+
+The specified string is copied before the function returns, so there is no need
+to keep it around.
+
+As long as your source file is encoded as UTF-8, you can use any Unicode
+characters directly in the source.
+
+@code
+glfwSetWindowTitle(window, "ラストエグザイル");
+@endcode
+
+If you are using C++11 or C11, you can use a UTF-8 string literal.
+
+@code
+glfwSetWindowTitle(window, u8"This is always a UTF-8 string");
+@endcode
+
+
+@subsection window_icon Window icon
+
+Decorated windows have icons on some platforms.  You can set this icon by
+specifying a list of candidate images with @ref glfwSetWindowIcon.
+
+@code
+GLFWimage images[2];
+images[0] = load_icon("my_icon.png");
+images[1] = load_icon("my_icon_small.png");
+
+glfwSetWindowIcon(window, 2, images);
+@endcode
+
+The image data is 32-bit, little-endian, non-premultiplied RGBA, i.e. eight bits
+per channel with the red channel first.  The pixels are arranged canonically as
+sequential rows, starting from the top-left corner.
+
+To revert to the default window icon, pass in an empty image array.
+
+@code
+glfwSetWindowIcon(window, 0, NULL);
+@endcode
+
+
+@subsection window_monitor Window monitor
+
+Full screen windows are associated with a specific monitor.  You can get the
+handle for this monitor with @ref glfwGetWindowMonitor.
+
+@code
+GLFWmonitor* monitor = glfwGetWindowMonitor(window);
+@endcode
+
+This monitor handle is one of those returned by @ref glfwGetMonitors.
+
+For windowed mode windows, this function returns `NULL`.  This is how to tell
+full screen windows from windowed mode windows.
+
+You can move windows between monitors or between full screen and windowed mode
+with @ref glfwSetWindowMonitor.  When making a window full screen on the same or
+on a different monitor, specify the desired monitor, resolution and refresh
+rate.  The position arguments are ignored.
+
+@code
+const GLFWvidmode* mode = glfwGetVideoMode(monitor);
+
+glfwSetWindowMonitor(window, monitor, 0, 0, mode->width, mode->height, mode->refreshRate);
+@endcode
+
+When making the window windowed, specify the desired position and size.  The
+refresh rate argument is ignored.
+
+@code
+glfwSetWindowMonitor(window, NULL, xpos, ypos, width, height, 0);
+@endcode
+
+This restores any previous window settings such as whether it is decorated,
+floating, resizable, has size or aspect ratio limits, etc..  To restore a window
+that was originally windowed to its original size and position, save these
+before making it full screen and then pass them in as above.
+
+
+@subsection window_iconify Window iconification
+
+Windows can be iconified (i.e. minimized) with @ref glfwIconifyWindow.
+
+@code
+glfwIconifyWindow(window);
+@endcode
+
+When a full screen window is iconified, the original video mode of its monitor
+is restored until the user or application restores the window.
+
+Iconified windows can be restored with @ref glfwRestoreWindow.  This function
+also restores windows from maximization.
+
+@code
+glfwRestoreWindow(window);
+@endcode
+
+When a full screen window is restored, the desired video mode is restored to its
+monitor as well.
+
+If you wish to be notified when a window is iconified or restored, whether by
+the user, system or your own code, set an iconify callback.
+
+@code
+glfwSetWindowIconifyCallback(window, window_iconify_callback);
+@endcode
+
+The callback function receives changes in the iconification state of the window.
+
+@code
+void window_iconify_callback(GLFWwindow* window, int iconified)
+{
+    if (iconified)
+    {
+        // The window was iconified
+    }
+    else
+    {
+        // The window was restored
+    }
+}
+@endcode
+
+You can also get the current iconification state with @ref glfwGetWindowAttrib.
+
+@code
+int iconified = glfwGetWindowAttrib(window, GLFW_ICONIFIED);
+@endcode
+
+
+@subsection window_maximize Window maximization
+
+Windows can be maximized (i.e. zoomed) with @ref glfwMaximizeWindow.
+
+@code
+glfwMaximizeWindow(window);
+@endcode
+
+Full screen windows cannot be maximized and passing a full screen window to this
+function does nothing.
+
+Maximized windows can be restored with @ref glfwRestoreWindow.  This function
+also restores windows from iconification.
+
+@code
+glfwRestoreWindow(window);
+@endcode
+
+If you wish to be notified when a window is maximized or restored, whether by
+the user, system or your own code, set a maximize callback.
+
+@code
+glfwSetWindowMaximizeCallback(window, window_maximize_callback);
+@endcode
+
+The callback function receives changes in the maximization state of the window.
+
+@code
+void window_maximize_callback(GLFWwindow* window, int maximized)
+{
+    if (maximized)
+    {
+        // The window was maximized
+    }
+    else
+    {
+        // The window was restored
+    }
+}
+@endcode
+
+You can also get the current maximization state with @ref glfwGetWindowAttrib.
+
+@code
+int maximized = glfwGetWindowAttrib(window, GLFW_MAXIMIZED);
+@endcode
+
+By default, newly created windows are not maximized.  You can change this
+behavior by setting the [GLFW_MAXIMIZED](@ref GLFW_MAXIMIZED_hint) window hint
+before creating the window.
+
+@code
+glfwWindowHint(GLFW_MAXIMIZED, GLFW_TRUE);
+@endcode
+
+
+@subsection window_hide Window visibility
+
+Windowed mode windows can be hidden with @ref glfwHideWindow.
+
+@code
+glfwHideWindow(window);
+@endcode
+
+This makes the window completely invisible to the user, including removing it
+from the task bar, dock or window list.  Full screen windows cannot be hidden
+and calling @ref glfwHideWindow on a full screen window does nothing.
+
+Hidden windows can be shown with @ref glfwShowWindow.
+
+@code
+glfwShowWindow(window);
+@endcode
+
+By default, this function will also set the input focus to that window. Set
+the [GLFW_FOCUS_ON_SHOW](@ref GLFW_FOCUS_ON_SHOW_hint) window hint to change
+this behavior for all newly created windows, or change the behavior for an
+existing window with @ref glfwSetWindowAttrib.
+
+You can also get the current visibility state with @ref glfwGetWindowAttrib.
+
+@code
+int visible = glfwGetWindowAttrib(window, GLFW_VISIBLE);
+@endcode
+
+By default, newly created windows are visible.  You can change this behavior by
+setting the [GLFW_VISIBLE](@ref GLFW_VISIBLE_hint) window hint before creating
+the window.
+
+@code
+glfwWindowHint(GLFW_VISIBLE, GLFW_FALSE);
+@endcode
+
+Windows created hidden are completely invisible to the user until shown.  This
+can be useful if you need to set up your window further before showing it, for
+example moving it to a specific location.
+
+
+@subsection window_focus Window input focus
+
+Windows can be given input focus and brought to the front with @ref
+glfwFocusWindow.
+
+@code
+glfwFocusWindow(window);
+@endcode
+
+Keep in mind that it can be very disruptive to the user when a window is forced
+to the top.  For a less disruptive way of getting the user's attention, see
+[attention requests](@ref window_attention).
+
+If you wish to be notified when a window gains or loses input focus, whether by
+the user, system or your own code, set a focus callback.
+
+@code
+glfwSetWindowFocusCallback(window, window_focus_callback);
+@endcode
+
+The callback function receives changes in the input focus state of the window.
+
+@code
+void window_focus_callback(GLFWwindow* window, int focused)
+{
+    if (focused)
+    {
+        // The window gained input focus
+    }
+    else
+    {
+        // The window lost input focus
+    }
+}
+@endcode
+
+You can also get the current input focus state with @ref glfwGetWindowAttrib.
+
+@code
+int focused = glfwGetWindowAttrib(window, GLFW_FOCUSED);
+@endcode
+
+By default, newly created windows are given input focus.  You can change this
+behavior by setting the [GLFW_FOCUSED](@ref GLFW_FOCUSED_hint) window hint
+before creating the window.
+
+@code
+glfwWindowHint(GLFW_FOCUSED, GLFW_FALSE);
+@endcode
+
+
+@subsection window_attention Window attention request
+
+If you wish to notify the user of an event without interrupting, you can request
+attention with @ref glfwRequestWindowAttention.
+
+@code
+glfwRequestWindowAttention(window);
+@endcode
+
+The system will highlight the specified window, or on platforms where this is
+not supported, the application as a whole.  Once the user has given it
+attention, the system will automatically end the request.
+
+
+@subsection window_refresh Window damage and refresh
+
+If you wish to be notified when the contents of a window is damaged and needs
+to be refreshed, set a window refresh callback.
+
+@code
+glfwSetWindowRefreshCallback(m_handle, window_refresh_callback);
+@endcode
+
+The callback function is called when the contents of the window needs to be
+refreshed.
+
+@code
+void window_refresh_callback(GLFWwindow* window)
+{
+    draw_editor_ui(window);
+    glfwSwapBuffers(window);
+}
+@endcode
+
+@note On compositing window systems such as Aero, Compiz or Aqua, where the
+window contents are saved off-screen, this callback might only be called when
+the window or framebuffer is resized.
+
+
+@subsection window_transparency Window transparency
+
+GLFW supports two kinds of transparency for windows; framebuffer transparency
+and whole window transparency.  A single window may not use both methods.  The
+results of doing this are undefined.
+
+Both methods require the platform to support it and not every version of every
+platform GLFW supports does this, so there are mechanisms to check whether the
+window really is transparent.
+
+Window framebuffers can be made transparent on a per-pixel per-frame basis with
+the [GLFW_TRANSPARENT_FRAMEBUFFER](@ref GLFW_TRANSPARENT_FRAMEBUFFER_hint)
+window hint.
+
+@code
+glfwWindowHint(GLFW_TRANSPARENT_FRAMEBUFFER, GLFW_TRUE);
+@endcode
+
+If supported by the system, the window content area will be composited with the
+background using the framebuffer per-pixel alpha channel.  This requires desktop
+compositing to be enabled on the system.  It does not affect window decorations.
+
+You can check whether the window framebuffer was successfully made transparent
+with the
+[GLFW_TRANSPARENT_FRAMEBUFFER](@ref GLFW_TRANSPARENT_FRAMEBUFFER_attrib)
+window attribute.
+
+@code
+if (glfwGetWindowAttrib(window, GLFW_TRANSPARENT_FRAMEBUFFER))
+{
+    // window framebuffer is currently transparent
+}
+@endcode
+
+GLFW comes with an example that enabled framebuffer transparency called `gears`.
+
+The opacity of the whole window, including any decorations, can be set with @ref
+glfwSetWindowOpacity.
+
+@code
+glfwSetWindowOpacity(window, 0.5f);
+@endcode
+
+The opacity (or alpha) value is a positive finite number between zero and one,
+where 0 (zero) is fully transparent and 1 (one) is fully opaque.  The initial
+opacity value for newly created windows is 1.
+
+The current opacity of a window can be queried with @ref glfwGetWindowOpacity.
+
+@code
+float opacity = glfwGetWindowOpacity(window);
+@endcode
+
+If the system does not support whole window transparency, this function always
+returns one.
+
+GLFW comes with a test program that lets you control whole window transparency
+at run-time called `opacity`.
+
+
+@subsection window_attribs Window attributes
+
+Windows have a number of attributes that can be returned using @ref
+glfwGetWindowAttrib.  Some reflect state that may change as a result of user
+interaction, (e.g. whether it has input focus), while others reflect inherent
+properties of the window (e.g. what kind of border it has).  Some are related to
+the window and others to its OpenGL or OpenGL ES context.
+
+@code
+if (glfwGetWindowAttrib(window, GLFW_FOCUSED))
+{
+    // window has input focus
+}
+@endcode
+
+The [GLFW_DECORATED](@ref GLFW_DECORATED_attrib),
+[GLFW_RESIZABLE](@ref GLFW_RESIZABLE_attrib),
+[GLFW_FLOATING](@ref GLFW_FLOATING_attrib),
+[GLFW_AUTO_ICONIFY](@ref GLFW_AUTO_ICONIFY_attrib) and
+[GLFW_FOCUS_ON_SHOW](@ref GLFW_FOCUS_ON_SHOW_attrib) window attributes can be
+changed with @ref glfwSetWindowAttrib.
+
+@code
+glfwSetWindowAttrib(window, GLFW_RESIZABLE, GLFW_FALSE);
+@endcode
+
+
+
+@subsubsection window_attribs_wnd Window related attributes

+window_hide for details.
+
+@anchor GLFW_RESIZABLE_attrib
+__GLFW_RESIZABLE__ indicates whether the specified window is resizable _by the

+[GLFW_RESIZABLE](@ref GLFW_RESIZABLE_hint) window hint or after with @ref
+glfwSetWindowAttrib.
+
+@anchor GLFW_DECORATED_attrib
+__GLFW_DECORATED__ indicates whether the specified window has decorations such
+as a border, a close widget, etc.  This can be set before creation with the

+glfwSetWindowAttrib.
+
+@anchor GLFW_AUTO_ICONIFY_attrib
+__GLFW_AUTO_ICONIFY__ indicates whether the specified full screen window is
+iconified on focus loss, a close widget, etc.  This can be set before creation
+with the [GLFW_AUTO_ICONIFY](@ref GLFW_AUTO_ICONIFY_hint) window hint or after
+with @ref glfwSetWindowAttrib.
+
+@anchor GLFW_FLOATING_attrib
+__GLFW_FLOATING__ indicates whether the specified window is floating, also
+called topmost or always-on-top.  This can be set before creation with the
+[GLFW_FLOATING](@ref GLFW_FLOATING_hint) window hint or after with @ref
+glfwSetWindowAttrib.
+
+@anchor GLFW_TRANSPARENT_FRAMEBUFFER_attrib
+__GLFW_TRANSPARENT_FRAMEBUFFER__ indicates whether the specified window has
+a transparent framebuffer, i.e. the window contents is composited with the
+background using the window framebuffer alpha channel.  See @ref
+window_transparency for details.
+
+@anchor GLFW_FOCUS_ON_SHOW_attrib
+__GLFW_FOCUS_ON_SHOW__ specifies whether the window will be given input
+focus when @ref glfwShowWindow is called. This can be set before creation
+with the [GLFW_FOCUS_ON_SHOW](@ref GLFW_FOCUS_ON_SHOW_hint) window hint or
+after with @ref glfwSetWindowAttrib.
+
+@subsubsection window_attribs_ctx Context related attributes
+
+@anchor GLFW_CLIENT_API_attrib
+__GLFW_CLIENT_API__ indicates the client API provided by the window's context;
+either `GLFW_OPENGL_API`, `GLFW_OPENGL_ES_API` or `GLFW_NO_API`.
+
+@anchor GLFW_CONTEXT_CREATION_API_attrib
+__GLFW_CONTEXT_CREATION_API__ indicates the context creation API used to create
+the window's context; either `GLFW_NATIVE_CONTEXT_API`, `GLFW_EGL_CONTEXT_API`
+or `GLFW_OSMESA_CONTEXT_API`.
+
+@anchor GLFW_CONTEXT_VERSION_MAJOR_attrib
+@anchor GLFW_CONTEXT_VERSION_MINOR_attrib
+@anchor GLFW_CONTEXT_REVISION_attrib
+__GLFW_CONTEXT_VERSION_MAJOR__, __GLFW_CONTEXT_VERSION_MINOR__ and
+__GLFW_CONTEXT_REVISION__ indicate the client API version of the window's
+context.
+
+@note Do not confuse these attributes with `GLFW_VERSION_MAJOR`,
+`GLFW_VERSION_MINOR` and `GLFW_VERSION_REVISION` which provide the API version
+of the GLFW header.
+
+@anchor GLFW_OPENGL_FORWARD_COMPAT_attrib
+__GLFW_OPENGL_FORWARD_COMPAT__ is `GLFW_TRUE` if the window's context is an
+OpenGL forward-compatible one, or `GLFW_FALSE` otherwise.
+
+@anchor GLFW_OPENGL_DEBUG_CONTEXT_attrib
+__GLFW_OPENGL_DEBUG_CONTEXT__ is `GLFW_TRUE` if the window's context is an
+OpenGL debug context, or `GLFW_FALSE` otherwise.
+
+@anchor GLFW_OPENGL_PROFILE_attrib
+__GLFW_OPENGL_PROFILE__ indicates the OpenGL profile used by the context.  This
+is `GLFW_OPENGL_CORE_PROFILE` or `GLFW_OPENGL_COMPAT_PROFILE` if the context
+uses a known profile, or `GLFW_OPENGL_ANY_PROFILE` if the OpenGL profile is
+unknown or the context is an OpenGL ES context.  Note that the returned profile
+may not match the profile bits of the context flags, as GLFW will try other
+means of detecting the profile when no bits are set.
+
+@anchor GLFW_CONTEXT_RELEASE_BEHAVIOR_attrib
+__GLFW_CONTEXT_RELEASE_BEHAVIOR__ indicates the release used by the context.
+Possible values are one of `GLFW_ANY_RELEASE_BEHAVIOR`,
+`GLFW_RELEASE_BEHAVIOR_FLUSH` or `GLFW_RELEASE_BEHAVIOR_NONE`.  If the
+behavior is `GLFW_ANY_RELEASE_BEHAVIOR`, the default behavior of the context
+creation API will be used.  If the behavior is `GLFW_RELEASE_BEHAVIOR_FLUSH`,
+the pipeline will be flushed whenever the context is released from being the
+current one.  If the behavior is `GLFW_RELEASE_BEHAVIOR_NONE`, the pipeline will
+not be flushed on release.
+
+@anchor GLFW_CONTEXT_NO_ERROR_attrib
+__GLFW_CONTEXT_NO_ERROR__ indicates whether errors are generated by the context.
+Possible values are `GLFW_TRUE` and `GLFW_FALSE`.  If enabled, situations that
+would have generated errors instead cause undefined behavior.
+
+@anchor GLFW_CONTEXT_ROBUSTNESS_attrib
+__GLFW_CONTEXT_ROBUSTNESS__ indicates the robustness strategy used by the
+context.  This is `GLFW_LOSE_CONTEXT_ON_RESET` or `GLFW_NO_RESET_NOTIFICATION`
+if the window's context supports robustness, or `GLFW_NO_ROBUSTNESS` otherwise.
+
+
+@subsubsection window_attribs_fb Framebuffer related attributes
+
+GLFW does not expose attributes of the default framebuffer (i.e. the framebuffer
+attached to the window) as these can be queried directly with either OpenGL,
+OpenGL ES or Vulkan.
+
+If you are using version 3.0 or later of OpenGL or OpenGL ES, the
+`glGetFramebufferAttachmentParameteriv` function can be used to retrieve the
+number of bits for the red, green, blue, alpha, depth and stencil buffer
+channels.  Otherwise, the `glGetIntegerv` function can be used.
+
+The number of MSAA samples are always retrieved with `glGetIntegerv`.  For
+contexts supporting framebuffer objects, the number of samples of the currently
+bound framebuffer is returned.
+
+Attribute    | glGetIntegerv     | glGetFramebufferAttachmentParameteriv
+------------ | ----------------- | -------------------------------------
+Red bits     | `GL_RED_BITS`     | `GL_FRAMEBUFFER_ATTACHMENT_RED_SIZE`
+Green bits   | `GL_GREEN_BITS`   | `GL_FRAMEBUFFER_ATTACHMENT_GREEN_SIZE`
+Blue bits    | `GL_BLUE_BITS`    | `GL_FRAMEBUFFER_ATTACHMENT_BLUE_SIZE`
+Alpha bits   | `GL_ALPHA_BITS`   | `GL_FRAMEBUFFER_ATTACHMENT_ALPHA_SIZE`
+Depth bits   | `GL_DEPTH_BITS`   | `GL_FRAMEBUFFER_ATTACHMENT_DEPTH_SIZE`
+Stencil bits | `GL_STENCIL_BITS` | `GL_FRAMEBUFFER_ATTACHMENT_STENCIL_SIZE`
+MSAA samples | `GL_SAMPLES`      | _Not provided by this function_
+
+When calling `glGetFramebufferAttachmentParameteriv`, the red, green, blue and
+alpha sizes are queried from the `GL_BACK_LEFT`, while the depth and stencil
+sizes are queried from the `GL_DEPTH` and `GL_STENCIL` attachments,
+respectively.
+
+
+@section buffer_swap Buffer swapping
+
+GLFW windows are by default double buffered.  That means that you have two
+rendering buffers; a front buffer and a back buffer.  The front buffer is
+the one being displayed and the back buffer the one you render to.
+
+When the entire frame has been rendered, it is time to swap the back and the
+front buffers in order to display what has been rendered and begin rendering
+a new frame.  This is done with @ref glfwSwapBuffers.
+
+@code
+glfwSwapBuffers(window);
+@endcode
+
+Sometimes it can be useful to select when the buffer swap will occur.  With the
+function @ref glfwSwapInterval it is possible to select the minimum number of
+monitor refreshes the driver should wait from the time @ref glfwSwapBuffers was
+called before swapping the buffers:
+
+@code
+glfwSwapInterval(1);
+@endcode
+
+If the interval is zero, the swap will take place immediately when @ref
+glfwSwapBuffers is called without waiting for a refresh.  Otherwise at least
+interval retraces will pass between each buffer swap.  Using a swap interval of
+zero can be useful for benchmarking purposes, when it is not desirable to
+measure the time it takes to wait for the vertical retrace.  However, a swap
+interval of one lets you avoid tearing.
+
+Note that this may not work on all machines, as some drivers have
+user-controlled settings that override any swap interval the application
+requests.
+
+A context that supports either the `WGL_EXT_swap_control_tear` or the
+`GLX_EXT_swap_control_tear` extension also accepts _negative_ swap intervals,
+which allows the driver to swap immediately even if a frame arrives a little bit
+late.  This trades the risk of visible tears for greater framerate stability.
+You can check for these extensions with @ref glfwExtensionSupported.

+/*****************************************************************************
+ * Title:   GLBoing
+ * Desc:    Tribute to Amiga Boing.
+ * Author:  Jim Brooks  <gfx@jimbrooks.org>
+ *          Original Amiga authors were R.J. Mical and Dale Luck.
+ *          GLFW conversion by Marcus Geelnard
+ * Notes:   - 360' = 2*PI [radian]
+ *
+ *          - Distances between objects are created by doing a relative
+ *            Z translations.
+ *
+ *          - Although OpenGL enticingly supports alpha-blending,
+ *            the shadow of the original Boing didn't affect the color
+ *            of the grid.
+ *
+ *          - [Marcus] Changed timing scheme from interval driven to frame-
+ *            time based animation steps (which results in much smoother
+ *            movement)
+ *
+ * History of Amiga Boing:
+ *
+ * Boing was demonstrated on the prototype Amiga (codenamed "Lorraine") in
+ * 1985. According to legend, it was written ad-hoc in one night by
+ * R. J. Mical and Dale Luck. Because the bouncing ball animation was so fast
+ * and smooth, attendees did not believe the Amiga prototype was really doing
+ * the rendering. Suspecting a trick, they began looking around the booth for
+ * a hidden computer or VCR.

+/*! @brief Creates a window and its associated context.
+ *
+ *  This function creates a window and its associated OpenGL or OpenGL ES
+ *  context.  Most of the options controlling how the window and its context
+ *  should be created are specified with [window hints](@ref window_hints).
+ *
+ *  Successful creation does not change which context is current.  Before you
+ *  can use the newly created context, you need to
+ *  [make it current](@ref context_current).  For information about the `share`
+ *  parameter, see @ref context_sharing.
+ *
+ *  The created window, framebuffer and context may differ from what you
+ *  requested, as not all parameters and hints are
+ *  [hard constraints](@ref window_hints_hard).  This includes the size of the
+ *  window, especially for full screen windows.  To query the actual attributes
+ *  of the created window, framebuffer and context, see @ref
+ *  glfwGetWindowAttrib, @ref glfwGetWindowSize and @ref glfwGetFramebufferSize.
+ *
+ *  To create a full screen window, you need to specify the monitor the window
+ *  will cover.  If no monitor is specified, the window will be windowed mode.
+ *  Unless you have a way for the user to choose a specific monitor, it is
+ *  recommended that you pick the primary monitor.  For more information on how
+ *  to query connected monitors, see @ref monitor_monitors.
+ *
+ *  For full screen windows, the specified size becomes the resolution of the
+ *  window's _desired video mode_.  As long as a full screen window is not
+ *  iconified, the supported video mode most closely matching the desired video
+ *  mode is set for the specified monitor.  For more information about full
+ *  screen windows, including the creation of so called _windowed full screen_
+ *  or _borderless full screen_ windows, see @ref window_windowed_full_screen.
+ *
+ *  Once you have created the window, you can switch it between windowed and
+ *  full screen mode with @ref glfwSetWindowMonitor.  This will not affect its
+ *  OpenGL or OpenGL ES context.
+ *
+ *  By default, newly created windows use the placement recommended by the
+ *  window system.  To create the window at a specific position, make it
+ *  initially invisible using the [GLFW_VISIBLE](@ref GLFW_VISIBLE_hint) window
+ *  hint, set its [position](@ref window_pos) and then [show](@ref window_hide)
+ *  it.
+ *
+ *  As long as at least one full screen window is not iconified, the screensaver
+ *  is prohibited from starting.
+ *
+ *  Window systems put limits on window sizes.  Very large or very small window
+ *  dimensions may be overridden by the window system on creation.  Check the
+ *  actual [size](@ref window_size) after creation.
+ *
+ *  The [swap interval](@ref buffer_swap) is not set during window creation and
+ *  the initial value may vary depending on driver settings and defaults.
+ *
+ *  @param[in] width The desired width, in screen coordinates, of the window.
+ *  This must be greater than zero.
+ *  @param[in] height The desired height, in screen coordinates, of the window.
+ *  This must be greater than zero.
+ *  @param[in] title The initial, UTF-8 encoded window title.
+ *  @param[in] monitor The monitor to use for full screen mode, or `NULL` for
+ *  windowed mode.
+ *  @param[in] share The window whose context to share resources with, or `NULL`
+ *  to not share resources.
+ *  @return The handle of the created window, or `NULL` if an
+ *  [error](@ref error_handling) occurred.
+ *
+ *  @errors Possible errors include @ref GLFW_NOT_INITIALIZED, @ref
+ *  GLFW_INVALID_ENUM, @ref GLFW_INVALID_VALUE, @ref GLFW_API_UNAVAILABLE, @ref
+ *  GLFW_VERSION_UNAVAILABLE, @ref GLFW_FORMAT_UNAVAILABLE and @ref
+ *  GLFW_PLATFORM_ERROR.
+ *
+ *  @remark @win32 Window creation will fail if the Microsoft GDI software
+ *  OpenGL implementation is the only one available.
+ *
+ *  @remark @win32 If the executable has an icon resource named `GLFW_ICON,` it
+ *  will be set as the initial icon for the window.  If no such icon is present,
+ *  the `IDI_APPLICATION` icon will be used instead.  To set a different icon,
+ *  see @ref glfwSetWindowIcon.
+ *
+ *  @remark @win32 The context to share resources with must not be current on
+ *  any other thread.
+ *
+ *  @remark @macos The OS only supports forward-compatible core profile contexts
+ *  for OpenGL versions 3.2 and later.  Before creating an OpenGL context of
+ *  version 3.2 or later you must set the
+ *  [GLFW_OPENGL_FORWARD_COMPAT](@ref GLFW_OPENGL_FORWARD_COMPAT_hint) and
+ *  [GLFW_OPENGL_PROFILE](@ref GLFW_OPENGL_PROFILE_hint) hints accordingly.
+ *  OpenGL 3.0 and 3.1 contexts are not supported at all on macOS.
+ *
+ *  @remark @macos The GLFW window has no icon, as it is not a document
+ *  window, but the dock icon will be the same as the application bundle's icon.
+ *  For more information on bundles, see the
+ *  [Bundle Programming Guide](https://developer.apple.com/library/mac/documentation/CoreFoundation/Conceptual/CFBundles/)
+ *  in the Mac Developer Library.
+ *
+ *  @remark @macos The first time a window is created the menu bar is created.
+ *  If GLFW finds a `MainMenu.nib` it is loaded and assumed to contain a menu
+ *  bar.  Otherwise a minimal menu bar is created manually with common commands
+ *  like Hide, Quit and About.  The About entry opens a minimal about dialog
+ *  with information from the application's bundle.  Menu bar creation can be
+ *  disabled entirely with the @ref GLFW_COCOA_MENUBAR init hint.
+ *
+ *  @remark @macos On OS X 10.10 and later the window frame will not be rendered
+ *  at full resolution on Retina displays unless the
+ *  [GLFW_COCOA_RETINA_FRAMEBUFFER](@ref GLFW_COCOA_RETINA_FRAMEBUFFER_hint)
+ *  hint is `GLFW_TRUE` and the `NSHighResolutionCapable` key is enabled in the
+ *  application bundle's `Info.plist`.  For more information, see
+ *  [High Resolution Guidelines for OS X](https://developer.apple.com/library/mac/documentation/GraphicsAnimation/Conceptual/HighResolutionOSX/Explained/Explained.html)
+ *  in the Mac Developer Library.  The GLFW test and example programs use
+ *  a custom `Info.plist` template for this, which can be found as
+ *  `CMake/MacOSXBundleInfo.plist.in` in the source tree.
+ *
+ *  @remark @macos When activating frame autosaving with
+ *  [GLFW_COCOA_FRAME_NAME](@ref GLFW_COCOA_FRAME_NAME_hint), the specified
+ *  window size and position may be overridden by previously saved values.
+ *
+ *  @remark @x11 Some window managers will not respect the placement of
+ *  initially hidden windows.
+ *
+ *  @remark @x11 Due to the asynchronous nature of X11, it may take a moment for
+ *  a window to reach its requested state.  This means you may not be able to
+ *  query the final size, position or other attributes directly after window
+ *  creation.
+ *
+ *  @remark @x11 The class part of the `WM_CLASS` window property will by
+ *  default be set to the window title passed to this function.  The instance
+ *  part will use the contents of the `RESOURCE_NAME` environment variable, if
+ *  present and not empty, or fall back to the window title.  Set the
+ *  [GLFW_X11_CLASS_NAME](@ref GLFW_X11_CLASS_NAME_hint) and
+ *  [GLFW_X11_INSTANCE_NAME](@ref GLFW_X11_INSTANCE_NAME_hint) window hints to
+ *  override this.
+ *
+ *  @remark @wayland Compositors should implement the xdg-decoration protocol
+ *  for GLFW to decorate the window properly.  If this protocol isn't
+ *  supported, or if the compositor prefers client-side decorations, a very
+ *  simple fallback frame will be drawn using the wp_viewporter protocol.  A
+ *  compositor can still emit close, maximize or fullscreen events, using for
+ *  instance a keybind mechanism.  If neither of these protocols is supported,
+ *  the window won't be decorated.
+ *
+ *  @remark @wayland A full screen window will not attempt to change the mode,
+ *  no matter what the requested size or refresh rate.

+ * Marcus: This code was originally written by Markus G. Kuhn.
+ * I have made some slight changes (trimmed it down a bit from >60 KB to
+ * 20 KB), but the functionality is the same.
+ */
+
+/*
+ * This module converts keysym values into the corresponding ISO 10646
+ * (UCS, Unicode) values.
+ *
+ * The array keysymtab[] contains pairs of X11 keysym values for graphical
+ * characters and the corresponding Unicode value. The function
+ * _glfwKeySym2Unicode() maps a keysym onto a Unicode value using a binary
+ * search, therefore keysymtab[] must remain SORTED by keysym value.
+ *
+ * We allow to represent any UCS character in the range U-00000000 to
+ * U-00FFFFFF by a keysym value in the range 0x01000000 to 0x01ffffff.
+ * This admittedly does not cover the entire 31-bit space of UCS, but
+ * it does cover all of the characters up to U-10FFFF, which can be
+ * represented by UTF-16, and more, and it is very unlikely that higher
+ * UCS codes will ever be assigned by ISO. So to get Unicode character
+ * U+ABCD you can directly use keysym 0x0100abcd.

+
+/*
+1. Introduction
+===============
+miniaudio is a single file library for audio playback and capture. To use it, do the following in one .c file:
+
+    ```c
+    #define MINIAUDIO_IMPLEMENTATION
+    #include "miniaudio.h"
+    ```
+
+You can do `#include "miniaudio.h"` in other parts of the program just like any other header.
+
+miniaudio uses the concept of a "device" as the abstraction for physical devices. The idea is that you choose a physical device to emit or capture audio from,
+and then move data to/from the device when miniaudio tells you to. Data is delivered to and from devices asynchronously via a callback which you specify when
+initializing the device.
+
+When initializing the device you first need to configure it. The device configuration allows you to specify things like the format of the data delivered via
+the callback, the size of the internal buffer and the ID of the device you want to emit or capture audio from.
+
+Once you have the device configuration set up you can initialize the device. When initializing a device you need to allocate memory for the device object
+beforehand. This gives the application complete control over how the memory is allocated. In the example below we initialize a playback device on the stack,
+but you could allocate it on the heap if that suits your situation better.
+
+    ```c
+    void data_callback(ma_device* pDevice, void* pOutput, const void* pInput, ma_uint32 frameCount)
+    {
+        // In playback mode copy data to pOutput. In capture mode read data from pInput. In full-duplex mode, both
+        // pOutput and pInput will be valid and you can move data from pInput into pOutput. Never process more than
+        // frameCount frames.
+    }
+
+    int main()
+    {
+        ma_device_config config = ma_device_config_init(ma_device_type_playback);
+        config.playback.format   = ma_format_f32;   // Set to ma_format_unknown to use the device's native format.
+        config.playback.channels = 2;               // Set to 0 to use the device's native channel count.
+        config.sampleRate        = 48000;           // Set to 0 to use the device's native sample rate.
+        config.dataCallback      = data_callback;   // This function will be called when miniaudio needs more data.
+        config.pUserData         = pMyCustomData;   // Can be accessed from the device object (device.pUserData).
+
+        ma_device device;
+        if (ma_device_init(NULL, &config, &device) != MA_SUCCESS) {
+            return -1;  // Failed to initialize the device.
+        }
+
+        ma_device_start(&device);     // The device is sleeping by default so you'll need to start it manually.
+
+        // Do something here. Probably your program's main loop.
+
+        ma_device_uninit(&device);    // This will stop the device so no need to do that manually.
+        return 0;
+    }
+    ```
+
+In the example above, `data_callback()` is where audio data is written and read from the device. The idea is in playback mode you cause sound to be emitted
+from the speakers by writing audio data to the output buffer (`pOutput` in the example). In capture mode you read data from the input buffer (`pInput`) to
+extract sound captured by the microphone. The `frameCount` parameter tells you how many frames can be written to the output buffer and read from the input
+buffer. A "frame" is one sample for each channel. For example, in a stereo stream (2 channels), one frame is 2 samples: one for the left, one for the right.
+The channel count is defined by the device config. The size in bytes of an individual sample is defined by the sample format which is also specified in the
+device config. Multi-channel audio data is always interleaved, which means the samples for each frame are stored next to each other in memory. For example, in
+a stereo stream the first pair of samples will be the left and right samples for the first frame, the second pair of samples will be the left and right samples
+for the second frame, etc.
+
+The configuration of the device is defined by the `ma_device_config` structure. The config object is always initialized with `ma_device_config_init()`. It's
+important to always initialize the config with this function as it initializes it with logical defaults and ensures your program doesn't break when new members
+are added to the `ma_device_config` structure. The example above uses a fairly simple and standard device configuration. The call to `ma_device_config_init()`
+takes a single parameter, which is whether or not the device is a playback, capture, duplex or loopback device (loopback devices are not supported on all
+backends). The `config.playback.format` member sets the sample format which can be one of the following (all formats are native-endian):
+
+    +---------------+----------------------------------------+---------------------------+
+    | Symbol        | Description                            | Range                     |
+    +---------------+----------------------------------------+---------------------------+

+
+The `config.playback.channels` member sets the number of channels to use with the device. The channel count cannot exceed MA_MAX_CHANNELS. The
+`config.sampleRate` member sets the sample rate (which must be the same for both playback and capture in full-duplex configurations). This is usually set to
+44100 or 48000, but can be set to anything. It's recommended to keep this between 8000 and 384000, however.
+
+Note that leaving the format, channel count and/or sample rate at their default values will result in the internal device's native configuration being used
+which is useful if you want to avoid the overhead of miniaudio's automatic data conversion.
+
+In addition to the sample format, channel count and sample rate, the data callback and user data pointer are also set via the config. The user data pointer is
+not passed into the callback as a parameter, but is instead set to the `pUserData` member of `ma_device` which you can access directly since all miniaudio
+structures are transparent.
+
+Initializing the device is done with `ma_device_init()`. This will return a result code telling you what went wrong, if anything. On success it will return
+`MA_SUCCESS`. After initialization is complete the device will be in a stopped state. To start it, use `ma_device_start()`. Uninitializing the device will stop
+it, which is what the example above does, but you can also stop the device with `ma_device_stop()`. To resume the device simply call `ma_device_start()` again.
+Note that it's important to never stop or start the device from inside the callback. This will result in a deadlock. Instead you set a variable or signal an
+event indicating that the device needs to stop and handle it in a different thread. The following APIs must never be called inside the callback:
+
+    ```c
+    ma_device_init()
+    ma_device_init_ex()
+    ma_device_uninit()
+    ma_device_start()
+    ma_device_stop()
+    ```
+
+You must never try uninitializing and reinitializing a device inside the callback. You must also never try to stop and start it from inside the callback. There
+are a few other things you shouldn't do in the callback depending on your requirements, however this isn't so much a thread-safety thing, but rather a real-
+time processing thing which is beyond the scope of this introduction.
+
+The example above demonstrates the initialization of a playback device, but it works exactly the same for capture. All you need to do is change the device type
+from `ma_device_type_playback` to `ma_device_type_capture` when setting up the config, like so:
+
+    ```c
+    ma_device_config config = ma_device_config_init(ma_device_type_capture);
+    config.capture.format   = MY_FORMAT;
+    config.capture.channels = MY_CHANNEL_COUNT;
+    ```
+
+In the data callback you just read from the input buffer (`pInput` in the example above) and leave the output buffer alone (it will be set to NULL when the
+device type is set to `ma_device_type_capture`).
+
+These are the available device types and how you should handle the buffers in the callback:
+
+    +-------------------------+--------------------------------------------------------+
+    | Device Type             | Callback Behavior                                      |
+    +-------------------------+--------------------------------------------------------+
+    | ma_device_type_playback | Write to output buffer, leave input buffer untouched.  |
+    | ma_device_type_capture  | Read from input buffer, leave output buffer untouched. |
+    | ma_device_type_duplex   | Read from input buffer, write to output buffer.        |
+    | ma_device_type_loopback | Read from input buffer, leave output buffer untouched. |
+    +-------------------------+--------------------------------------------------------+
+
+You will notice in the example above that the sample format and channel count is specified separately for playback and capture. This is to support different
+data formats between the playback and capture devices in a full-duplex system. An example may be that you want to capture audio data as a monaural stream (one
+channel), but output sound to a stereo speaker system. Note that if you use different formats between playback and capture in a full-duplex configuration you
+will need to convert the data yourself. There are functions available to help you do this which will be explained later.
+
+The example above did not specify a physical device to connect to which means it will use the operating system's default device. If you have multiple physical
+devices connected and you want to use a specific one you will need to specify the device ID in the configuration, like so:
+
+    ```c
+    config.playback.pDeviceID = pMyPlaybackDeviceID;    // Only if requesting a playback or duplex device.
+    config.capture.pDeviceID = pMyCaptureDeviceID;      // Only if requesting a capture, duplex or loopback device.
+    ```
+
+To retrieve the device ID you will need to perform device enumeration, however this requires the use of a new concept called the "context". Conceptually
+speaking the context sits above the device. There is one context to many devices. The purpose of the context is to represent the backend at a more global level
+and to perform operations outside the scope of an individual device. Mainly it is used for performing run-time linking against backend libraries, initializing
+backends and enumerating devices. The example below shows how to enumerate devices.
+
+    ```c
+    ma_context context;
+    if (ma_context_init(NULL, 0, NULL, &context) != MA_SUCCESS) {
+        // Error.
+    }
+
+    ma_device_info* pPlaybackInfos;
+    ma_uint32 playbackCount;
+    ma_device_info* pCaptureInfos;
+    ma_uint32 captureCount;
+    if (ma_context_get_devices(&context, &pPlaybackInfos, &playbackCount, &pCaptureInfos, &captureCount) != MA_SUCCESS) {
+        // Error.
+    }
+
+    // Loop over each device info and do something with it. Here we just print the name with their index. You may want
+    // to give the user the opportunity to choose which device they'd prefer.
+    for (ma_uint32 iDevice = 0; iDevice < playbackCount; iDevice += 1) {
+        printf("%d - %s\n", iDevice, pPlaybackInfos[iDevice].name);
+    }
+
+    ma_device_config config = ma_device_config_init(ma_device_type_playback);
+    config.playback.pDeviceID = &pPlaybackInfos[chosenPlaybackDeviceIndex].id;
+    config.playback.format    = MY_FORMAT;
+    config.playback.channels  = MY_CHANNEL_COUNT;
+    config.sampleRate         = MY_SAMPLE_RATE;
+    config.dataCallback       = data_callback;
+    config.pUserData          = pMyCustomData;
+
+    ma_device device;
+    if (ma_device_init(&context, &config, &device) != MA_SUCCESS) {
+        // Error
+    }
+
+    ...
+
+    ma_device_uninit(&device);
+    ma_context_uninit(&context);
+    ```
+
+The first thing we do in this example is initialize a `ma_context` object with `ma_context_init()`. The first parameter is a pointer to a list of `ma_backend`
+values which are used to override the default backend priorities. When this is NULL, as in this example, miniaudio's default priorities are used. The second
+parameter is the number of backends listed in the array pointed to by the first parameter. The third parameter is a pointer to a `ma_context_config` object
+which can be NULL, in which case defaults are used. The context configuration is used for setting the logging callback, custom memory allocation callbacks,
+user-defined data and some backend-specific configurations.
+
+Once the context has been initialized you can enumerate devices. In the example above we use the simpler `ma_context_get_devices()`, however you can also use a
+callback for handling devices by using `ma_context_enumerate_devices()`. When using `ma_context_get_devices()` you provide a pointer to a pointer that will,
+upon output, be set to a pointer to a buffer containing a list of `ma_device_info` structures. You also provide a pointer to an unsigned integer that will
+receive the number of items in the returned buffer. Do not free the returned buffers as their memory is managed internally by miniaudio.
+
+The `ma_device_info` structure contains an `id` member which is the ID you pass to the device config. It also contains the name of the device which is useful
+for presenting a list of devices to the user via the UI.
+
+When creating your own context you will want to pass it to `ma_device_init()` when initializing the device. Passing in NULL, like we do in the first example,
+will result in miniaudio creating the context for you, which you don't want to do since you've already created a context. Note that internally the context is
+only tracked by it's pointer which means you must not change the location of the `ma_context` object. If this is an issue, consider using `malloc()` to
+allocate memory for the context.

+
+2. Building
+===========
+miniaudio should work cleanly out of the box without the need to download or install any dependencies. See below for platform-specific details.
+
+
+2.1. Windows
+------------
+The Windows build should compile cleanly on all popular compilers without the need to configure any include paths nor link to any libraries.
+
+2.2. macOS and iOS
+------------------
+The macOS build should compile cleanly without the need to download any dependencies nor link to any libraries or frameworks. The iOS build needs to be
+compiled as Objective-C (sorry) and will need to link the relevant frameworks but should Just Work with Xcode. Compiling through the command line requires
+linking to `-lpthread` and `-lm`.
+
+2.3. Linux
+----------
+The Linux build only requires linking to `-ldl`, `-lpthread` and `-lm`. You do not need any development packages.
+
+2.4. BSD
+--------
+The BSD build only requires linking to `-lpthread` and `-lm`. NetBSD uses audio(4), OpenBSD uses sndio and FreeBSD uses OSS.
+
+2.5. Android
+------------
+AAudio is the highest priority backend on Android. This should work out of the box without needing any kind of compiler configuration. Support for AAudio
+starts with Android 8 which means older versions will fall back to OpenSL|ES which requires API level 16+.
+
+2.6. Emscripten
+---------------
+The Emscripten build emits Web Audio JavaScript directly and should Just Work without any configuration. You cannot use -std=c* compiler flags, nor -ansi.
+
+
+2.7. Build Options

+
+
+3. Definitions
+==============
+This section defines common terms used throughout miniaudio. Unfortunately there is often ambiguity in the use of terms throughout the audio space, so this
+section is intended to clarify how miniaudio uses each term.
+
+3.1. Sample
+-----------
+A sample is a single unit of audio data. If the sample format is f32, then one sample is one 32-bit floating point number.
+
+3.2. Frame / PCM Frame
+----------------------
+A frame is a group of samples equal to the number of channels. For a stereo stream a frame is 2 samples, a mono frame is 1 sample, a 5.1 surround sound frame
+is 6 samples, etc. The terms "frame" and "PCM frame" are the same thing in miniaudio. Note that this is different to a compressed frame. If ever miniaudio
+needs to refer to a compressed frame, such as a FLAC frame, it will always clarify what it's referring to with something like "FLAC frame".
+
+3.3. Channel
+------------
+A stream of monaural audio that is emitted from an individual speaker in a speaker system, or received from an individual microphone in a microphone system. A
+stereo stream has two channels (a left channel, and a right channel), a 5.1 surround sound system has 6 channels, etc. Some audio systems refer to a channel as
+a complex audio stream that's mixed with other channels to produce the final mix - this is completely different to miniaudio's use of the term "channel" and
+should not be confused.
+
+3.4. Sample Rate
+----------------
+The sample rate in miniaudio is always expressed in Hz, such as 44100, 48000, etc. It's the number of PCM frames that are processed per second.
+
+3.5. Formats
+------------
+Throughout miniaudio you will see references to different sample formats:
+
+    +---------------+----------------------------------------+---------------------------+
+    | Symbol        | Description                            | Range                     |
+    +---------------+----------------------------------------+---------------------------+
+    | ma_format_f32 | 32-bit floating point                  | [-1, 1]                   |
+    | ma_format_s16 | 16-bit signed integer                  | [-32768, 32767]           |
+    | ma_format_s24 | 24-bit signed integer (tightly packed) | [-8388608, 8388607]       |
+    | ma_format_s32 | 32-bit signed integer                  | [-2147483648, 2147483647] |
+    | ma_format_u8  | 8-bit unsigned integer                 | [0, 255]                  |
+    +---------------+----------------------------------------+---------------------------+
+
+All formats are native-endian.
+
+
+
+4. Decoding
+===========
+The `ma_decoder` API is used for reading audio files. The following formats are supported:
+
+    +---------+------------------+----------+
+    | Format  | Decoding Backend | Built-In |
+    +---------+------------------+----------+
+    | WAV     | dr_wav           | Yes      |
+    | MP3     | dr_mp3           | Yes      |
+    | FLAC    | dr_flac          | Yes      |
+    | Vorbis  | stb_vorbis       | No       |
+    +---------+------------------+----------+
+
+Vorbis is supported via stb_vorbis which can be enabled by including the header section before the implementation of miniaudio, like the following:
+
+    ```c
+    #define STB_VORBIS_HEADER_ONLY
+    #include "extras/stb_vorbis.c"    // Enables Vorbis decoding.
+
+    #define MINIAUDIO_IMPLEMENTATION
+    #include "miniaudio.h"
+
+    // The stb_vorbis implementation must come after the implementation of miniaudio.
+    #undef STB_VORBIS_HEADER_ONLY
+    #include "extras/stb_vorbis.c"
+    ```
+
+A copy of stb_vorbis is included in the "extras" folder in the miniaudio repository (https://github.com/mackron/miniaudio).
+
+Built-in decoders are amalgamated into the implementation section of miniaudio. You can disable the built-in decoders by specifying one or more of the
+following options before the miniaudio implementation:
+
+    ```c
+    #define MA_NO_WAV
+    #define MA_NO_MP3
+    #define MA_NO_FLAC
+    ```
+
+Disabling built-in decoding libraries is useful if you use these libraries independantly of the `ma_decoder` API.
+
+A decoder can be initialized from a file with `ma_decoder_init_file()`, a block of memory with `ma_decoder_init_memory()`, or from data delivered via callbacks
+with `ma_decoder_init()`. Here is an example for loading a decoder from a file:
+
+    ```c
+    ma_decoder decoder;
+    ma_result result = ma_decoder_init_file("MySong.mp3", NULL, &decoder);
+    if (result != MA_SUCCESS) {
+        return false;   // An error occurred.
+    }
+
+    ...
+
+    ma_decoder_uninit(&decoder);
+    ```
+
+When initializing a decoder, you can optionally pass in a pointer to a ma_decoder_config object (the NULL argument in the example above) which allows you to
+configure the output format, channel count, sample rate and channel map:
+
+    ```c
+    ma_decoder_config config = ma_decoder_config_init(ma_format_f32, 2, 48000);
+    ```
+
+When passing in NULL for decoder config in `ma_decoder_init*()`, the output format will be the same as that defined by the decoding backend.
+
+Data is read from the decoder as PCM frames. This will return the number of PCM frames actually read. If the return value is less than the requested number of
+PCM frames it means you've reached the end:
+
+    ```c
+    ma_uint64 framesRead = ma_decoder_read_pcm_frames(pDecoder, pFrames, framesToRead);
+    if (framesRead < framesToRead) {
+        // Reached the end.
+    }
+    ```
+
+You can also seek to a specific frame like so:
+
+    ```c
+    ma_result result = ma_decoder_seek_to_pcm_frame(pDecoder, targetFrame);
+    if (result != MA_SUCCESS) {
+        return false;   // An error occurred.
+    }
+    ```
+
+If you want to loop back to the start, you can simply seek back to the first PCM frame:
+
+    ```c
+    ma_decoder_seek_to_pcm_frame(pDecoder, 0);
+    ```
+
+When loading a decoder, miniaudio uses a trial and error technique to find the appropriate decoding backend. This can be unnecessarily inefficient if the type
+is already known. In this case you can use the `_wav`, `_mp3`, etc. varients of the aforementioned initialization APIs:
+
+    ```c
+    ma_decoder_init_wav()
+    ma_decoder_init_mp3()
+    ma_decoder_init_memory_wav()
+    ma_decoder_init_memory_mp3()
+    ma_decoder_init_file_wav()
+    ma_decoder_init_file_mp3()
+    etc.
+    ```
+
+The `ma_decoder_init_file()` API will try using the file extension to determine which decoding backend to prefer.
+
+
+
+5. Encoding
+===========
+The `ma_encoding` API is used for writing audio files. The only supported output format is WAV which is achieved via dr_wav which is amalgamated into the
+implementation section of miniaudio. This can be disabled by specifying the following option before the implementation of miniaudio:
+
+    ```c
+    #define MA_NO_WAV
+    ```
+
+An encoder can be initialized to write to a file with `ma_encoder_init_file()` or from data delivered via callbacks with `ma_encoder_init()`. Below is an
+example for initializing an encoder to output to a file.
+
+    ```c
+    ma_encoder_config config = ma_encoder_config_init(ma_resource_format_wav, FORMAT, CHANNELS, SAMPLE_RATE);
+    ma_encoder encoder;
+    ma_result result = ma_encoder_init_file("my_file.wav", &config, &encoder);
+    if (result != MA_SUCCESS) {
+        // Error
+    }
+
+    ...
+
+    ma_encoder_uninit(&encoder);
+    ```
+
+When initializing an encoder you must specify a config which is initialized with `ma_encoder_config_init()`. Here you must specify the file type, the output
+sample format, output channel count and output sample rate. The following file types are supported:
+
+    +------------------------+-------------+
+    | Enum                   | Description |
+    +------------------------+-------------+
+    | ma_resource_format_wav | WAV         |
+    +------------------------+-------------+
+
+If the format, channel count or sample rate is not supported by the output file type an error will be returned. The encoder will not perform data conversion so
+you will need to convert it before outputting any audio data. To output audio data, use `ma_encoder_write_pcm_frames()`, like in the example below:
+
+    ```c
+    framesWritten = ma_encoder_write_pcm_frames(&encoder, pPCMFramesToWrite, framesToWrite);
+    ```
+
+Encoders must be uninitialized with `ma_encoder_uninit()`.
+
+
+6. Data Conversion
+==================
+A data conversion API is included with miniaudio which supports the majority of data conversion requirements. This supports conversion between sample formats,
+channel counts (with channel mapping) and sample rates.
+
+
+6.1. Sample Format Conversion
+-----------------------------
+Conversion between sample formats is achieved with the `ma_pcm_*_to_*()`, `ma_pcm_convert()` and `ma_convert_pcm_frames_format()` APIs. Use `ma_pcm_*_to_*()`
+to convert between two specific formats. Use `ma_pcm_convert()` to convert based on a `ma_format` variable. Use `ma_convert_pcm_frames_format()` to convert
+PCM frames where you want to specify the frame count and channel count as a variable instead of the total sample count.
+
+
+6.1.1. Dithering
+----------------
+Dithering can be set using the ditherMode parameter.
+
+The different dithering modes include the following, in order of efficiency:
+
+    +-----------+--------------------------+
+    | Type      | Enum Token               |
+    +-----------+--------------------------+
+    | None      | ma_dither_mode_none      |
+    | Rectangle | ma_dither_mode_rectangle |
+    | Triangle  | ma_dither_mode_triangle  |
+    +-----------+--------------------------+
+
+Note that even if the dither mode is set to something other than `ma_dither_mode_none`, it will be ignored for conversions where dithering is not needed.
+Dithering is available for the following conversions:
+
+    ```
+    s16 -> u8
+    s24 -> u8
+    s32 -> u8
+    f32 -> u8
+    s24 -> s16
+    s32 -> s16
+    f32 -> s16
+    ```
+
+Note that it is not an error to pass something other than ma_dither_mode_none for conversions where dither is not used. It will just be ignored.
+
+
+
+6.2. Channel Conversion
+-----------------------
+Channel conversion is used for channel rearrangement and conversion from one channel count to another. The `ma_channel_converter` API is used for channel
+conversion. Below is an example of initializing a simple channel converter which converts from mono to stereo.
+
+    ```c
+    ma_channel_converter_config config = ma_channel_converter_config_init(
+        ma_format,                      // Sample format
+        1,                              // Input channels
+        NULL,                           // Input channel map
+        2,                              // Output channels
+        NULL,                           // Output channel map
+        ma_channel_mix_mode_default);   // The mixing algorithm to use when combining channels.
+
+    result = ma_channel_converter_init(&config, &converter);
+    if (result != MA_SUCCESS) {
+        // Error.
+    }
+    ```
+
+To perform the conversion simply call `ma_channel_converter_process_pcm_frames()` like so:
+
+    ```c
+    ma_result result = ma_channel_converter_process_pcm_frames(&converter, pFramesOut, pFramesIn, frameCount);
+    if (result != MA_SUCCESS) {
+        // Error.
+    }
+    ```
+
+It is up to the caller to ensure the output buffer is large enough to accomodate the new PCM frames.
+
+Input and output PCM frames are always interleaved. Deinterleaved layouts are not supported.
+
+
+6.2.1. Channel Mapping
+----------------------
+In addition to converting from one channel count to another, like the example above, the channel converter can also be used to rearrange channels. When
+initializing the channel converter, you can optionally pass in channel maps for both the input and output frames. If the channel counts are the same, and each
+channel map contains the same channel positions with the exception that they're in a different order, a simple shuffling of the channels will be performed. If,
+however, there is not a 1:1 mapping of channel positions, or the channel counts differ, the input channels will be mixed based on a mixing mode which is
+specified when initializing the `ma_channel_converter_config` object.
+
+When converting from mono to multi-channel, the mono channel is simply copied to each output channel. When going the other way around, the audio of each output
+channel is simply averaged and copied to the mono channel.
+
+In more complicated cases blending is used. The `ma_channel_mix_mode_simple` mode will drop excess channels and silence extra channels. For example, converting
+from 4 to 2 channels, the 3rd and 4th channels will be dropped, whereas converting from 2 to 4 channels will put silence into the 3rd and 4th channels.
+
+The `ma_channel_mix_mode_rectangle` mode uses spacial locality based on a rectangle to compute a simple distribution between input and output. Imagine sitting
+in the middle of a room, with speakers on the walls representing channel positions. The MA_CHANNEL_FRONT_LEFT position can be thought of as being in the corner
+of the front and left walls.
+
+Finally, the `ma_channel_mix_mode_custom_weights` mode can be used to use custom user-defined weights. Custom weights can be passed in as the last parameter of
+`ma_channel_converter_config_init()`.
+
+Predefined channel maps can be retrieved with `ma_get_standard_channel_map()`. This takes a `ma_standard_channel_map` enum as it's first parameter, which can
+be one of the following:
+
+    +-----------------------------------+-----------------------------------------------------------+
+    | Name                              | Description                                               |

+    | Other         | All channels set to 0. This     |
+    |               | is equivalent to the same       |
+    |               | mapping as the device.          |
+    +---------------+---------------------------------+
+
+
+
+6.3. Resampling
+---------------
+Resampling is achieved with the `ma_resampler` object. To create a resampler object, do something like the following:
+
+    ```c
+    ma_resampler_config config = ma_resampler_config_init(
+        ma_format_s16,
+        channels,
+        sampleRateIn,
+        sampleRateOut,
+        ma_resample_algorithm_linear);
+
+    ma_resampler resampler;
+    ma_result result = ma_resampler_init(&config, &resampler);
+    if (result != MA_SUCCESS) {
+        // An error occurred...
+    }
+    ```
+
+Do the following to uninitialize the resampler:
+
+    ```c
+    ma_resampler_uninit(&resampler);
+    ```
+
+The following example shows how data can be processed
+
+    ```c
+    ma_uint64 frameCountIn  = 1000;
+    ma_uint64 frameCountOut = 2000;
+    ma_result result = ma_resampler_process_pcm_frames(&resampler, pFramesIn, &frameCountIn, pFramesOut, &frameCountOut);
+    if (result != MA_SUCCESS) {
+        // An error occurred...
+    }
+
+    // At this point, frameCountIn contains the number of input frames that were consumed and frameCountOut contains the
+    // number of output frames written.
+    ```
+
+To initialize the resampler you first need to set up a config (`ma_resampler_config`) with `ma_resampler_config_init()`. You need to specify the sample format
+you want to use, the number of channels, the input and output sample rate, and the algorithm.
+
+The sample format can be either `ma_format_s16` or `ma_format_f32`. If you need a different format you will need to perform pre- and post-conversions yourself
+where necessary. Note that the format is the same for both input and output. The format cannot be changed after initialization.
+
+The resampler supports multiple channels and is always interleaved (both input and output). The channel count cannot be changed after initialization.
+
+The sample rates can be anything other than zero, and are always specified in hertz. They should be set to something like 44100, etc. The sample rate is the
+only configuration property that can be changed after initialization.
+
+The miniaudio resampler supports multiple algorithms:
+
+    +-----------+------------------------------+
+    | Algorithm | Enum Token                   |
+    +-----------+------------------------------+
+    | Linear    | ma_resample_algorithm_linear |
+    | Speex     | ma_resample_algorithm_speex  |
+    +-----------+------------------------------+
+
+Because Speex is not public domain it is strictly opt-in and the code is stored in separate files. if you opt-in to the Speex backend you will need to consider
+it's license, the text of which can be found in it's source files in "extras/speex_resampler". Details on how to opt-in to the Speex resampler is explained in
+the Speex Resampler section below.
+
+The algorithm cannot be changed after initialization.
+
+Processing always happens on a per PCM frame basis and always assumes interleaved input and output. De-interleaved processing is not supported. To process
+frames, use `ma_resampler_process_pcm_frames()`. On input, this function takes the number of output frames you can fit in the output buffer and the number of
+input frames contained in the input buffer. On output these variables contain the number of output frames that were written to the output buffer and the
+number of input frames that were consumed in the process. You can pass in NULL for the input buffer in which case it will be treated as an infinitely large
+buffer of zeros. The output buffer can also be NULL, in which case the processing will be treated as seek.
+
+The sample rate can be changed dynamically on the fly. You can change this with explicit sample rates with `ma_resampler_set_rate()` and also with a decimal
+ratio with `ma_resampler_set_rate_ratio()`. The ratio is in/out.
+
+Sometimes it's useful to know exactly how many input frames will be required to output a specific number of frames. You can calculate this with
+`ma_resampler_get_required_input_frame_count()`. Likewise, it's sometimes useful to know exactly how many frames would be output given a certain number of
+input frames. You can do this with `ma_resampler_get_expected_output_frame_count()`.
+
+Due to the nature of how resampling works, the resampler introduces some latency. This can be retrieved in terms of both the input rate and the output rate
+with `ma_resampler_get_input_latency()` and `ma_resampler_get_output_latency()`.
+
+
+6.3.1. Resampling Algorithms
+----------------------------
+The choice of resampling algorithm depends on your situation and requirements. The linear resampler is the most efficient and has the least amount of latency,
+but at the expense of poorer quality. The Speex resampler is higher quality, but slower with more latency. It also performs several heap allocations internally
+for memory management.
+
+
+6.3.1.1. Linear Resampling
+--------------------------
+The linear resampler is the fastest, but comes at the expense of poorer quality. There is, however, some control over the quality of the linear resampler which
+may make it a suitable option depending on your requirements.
+
+The linear resampler performs low-pass filtering before or after downsampling or upsampling, depending on the sample rates you're converting between. When
+decreasing the sample rate, the low-pass filter will be applied before downsampling. When increasing the rate it will be performed after upsampling. By default
+a fourth order low-pass filter will be applied. This can be configured via the `lpfOrder` configuration variable. Setting this to 0 will disable filtering.
+
+The low-pass filter has a cutoff frequency which defaults to half the sample rate of the lowest of the input and output sample rates (Nyquist Frequency). This
+can be controlled with the `lpfNyquistFactor` config variable. This defaults to 1, and should be in the range of 0..1, although a value of 0 does not make
+sense and should be avoided. A value of 1 will use the Nyquist Frequency as the cutoff. A value of 0.5 will use half the Nyquist Frequency as the cutoff, etc.
+Values less than 1 will result in more washed out sound due to more of the higher frequencies being removed. This config variable has no impact on performance
+and is a purely perceptual configuration.
+
+The API for the linear resampler is the same as the main resampler API, only it's called `ma_linear_resampler`.
+
+
+6.3.1.2. Speex Resampling
+-------------------------
+The Speex resampler is made up of third party code which is released under the BSD license. Because it is licensed differently to miniaudio, which is public
+domain, it is strictly opt-in and all of it's code is stored in separate files. If you opt-in to the Speex resampler you must consider the license text in it's
+source files. To opt-in, you must first #include the following file before the implementation of miniaudio.h:
+
+    ```c
+    #include "extras/speex_resampler/ma_speex_resampler.h"
+    ```
+
+Both the header and implementation is contained within the same file. The implementation can be included in your program like so:
+
+    ```c
+    #define MINIAUDIO_SPEEX_RESAMPLER_IMPLEMENTATION
+    #include "extras/speex_resampler/ma_speex_resampler.h"
+    ```
+
+Note that even if you opt-in to the Speex backend, miniaudio won't use it unless you explicitly ask for it in the respective config of the object you are
+initializing. If you try to use the Speex resampler without opting in, initialization of the `ma_resampler` object will fail with `MA_NO_BACKEND`.
+
+The only configuration option to consider with the Speex resampler is the `speex.quality` config variable. This is a value between 0 and 10, with 0 being
+the fastest with the poorest quality and 10 being the slowest with the highest quality. The default value is 3.
+
+
+
+6.4. General Data Conversion
+----------------------------
+The `ma_data_converter` API can be used to wrap sample format conversion, channel conversion and resampling into one operation. This is what miniaudio uses
+internally to convert between the format requested when the device was initialized and the format of the backend's native device. The API for general data
+conversion is very similar to the resampling API. Create a `ma_data_converter` object like this:
+
+    ```c
+    ma_data_converter_config config = ma_data_converter_config_init(
+        inputFormat,
+        outputFormat,
+        inputChannels,
+        outputChannels,
+        inputSampleRate,
+        outputSampleRate
+    );
+
+    ma_data_converter converter;
+    ma_result result = ma_data_converter_init(&config, &converter);
+    if (result != MA_SUCCESS) {
+        // An error occurred...
+    }
+    ```
+
+In the example above we use `ma_data_converter_config_init()` to initialize the config, however there's many more properties that can be configured, such as
+channel maps and resampling quality. Something like the following may be more suitable depending on your requirements:
+
+    ```c
+    ma_data_converter_config config = ma_data_converter_config_init_default();
+    config.formatIn = inputFormat;
+    config.formatOut = outputFormat;
+    config.channelsIn = inputChannels;
+    config.channelsOut = outputChannels;
+    config.sampleRateIn = inputSampleRate;
+    config.sampleRateOut = outputSampleRate;
+    ma_get_standard_channel_map(ma_standard_channel_map_flac, config.channelCountIn, config.channelMapIn);
+    config.resampling.linear.lpfOrder = MA_MAX_FILTER_ORDER;
+    ```
+
+Do the following to uninitialize the data converter:
+
+    ```c
+    ma_data_converter_uninit(&converter);
+    ```
+
+The following example shows how data can be processed
+
+    ```c
+    ma_uint64 frameCountIn  = 1000;
+    ma_uint64 frameCountOut = 2000;
+    ma_result result = ma_data_converter_process_pcm_frames(&converter, pFramesIn, &frameCountIn, pFramesOut, &frameCountOut);
+    if (result != MA_SUCCESS) {
+        // An error occurred...
+    }
+
+    // At this point, frameCountIn contains the number of input frames that were consumed and frameCountOut contains the number
+    // of output frames written.
+    ```
+
+The data converter supports multiple channels and is always interleaved (both input and output). The channel count cannot be changed after initialization.
+
+Sample rates can be anything other than zero, and are always specified in hertz. They should be set to something like 44100, etc. The sample rate is the only
+configuration property that can be changed after initialization, but only if the `resampling.allowDynamicSampleRate` member of `ma_data_converter_config` is
+set to MA_TRUE. To change the sample rate, use `ma_data_converter_set_rate()` or `ma_data_converter_set_rate_ratio()`. The ratio must be in/out. The resampling
+algorithm cannot be changed after initialization.
+
+Processing always happens on a per PCM frame basis and always assumes interleaved input and output. De-interleaved processing is not supported. To process
+frames, use `ma_data_converter_process_pcm_frames()`. On input, this function takes the number of output frames you can fit in the output buffer and the number
+of input frames contained in the input buffer. On output these variables contain the number of output frames that were written to the output buffer and the
+number of input frames that were consumed in the process. You can pass in NULL for the input buffer in which case it will be treated as an infinitely large
+buffer of zeros. The output buffer can also be NULL, in which case the processing will be treated as seek.
+
+Sometimes it's useful to know exactly how many input frames will be required to output a specific number of frames. You can calculate this with
+`ma_data_converter_get_required_input_frame_count()`. Likewise, it's sometimes useful to know exactly how many frames would be output given a certain number of
+input frames. You can do this with `ma_data_converter_get_expected_output_frame_count()`.
+
+Due to the nature of how resampling works, the data converter introduces some latency if resampling is required. This can be retrieved in terms of both the
+input rate and the output rate with `ma_data_converter_get_input_latency()` and `ma_data_converter_get_output_latency()`.
+
+
+
+7. Filtering
+============
+
+7.1. Biquad Filtering
+---------------------
+Biquad filtering is achieved with the `ma_biquad` API. Example:
+
+    ```c
+    ma_biquad_config config = ma_biquad_config_init(ma_format_f32, channels, b0, b1, b2, a0, a1, a2);
+    ma_result result = ma_biquad_init(&config, &biquad);
+    if (result != MA_SUCCESS) {
+        // Error.
+    }
+
+    ...
+
+    ma_biquad_process_pcm_frames(&biquad, pFramesOut, pFramesIn, frameCount);
+    ```
+
+Biquad filtering is implemented using transposed direct form 2. The numerator coefficients are b0, b1 and b2, and the denominator coefficients are a0, a1 and
+a2. The a0 coefficient is required and coefficients must not be pre-normalized.
+
+Supported formats are `ma_format_s16` and `ma_format_f32`. If you need to use a different format you need to convert it yourself beforehand. When using
+`ma_format_s16` the biquad filter will use fixed point arithmetic. When using `ma_format_f32`, floating point arithmetic will be used.
+
+Input and output frames are always interleaved.
+
+Filtering can be applied in-place by passing in the same pointer for both the input and output buffers, like so:
+
+    ```c
+    ma_biquad_process_pcm_frames(&biquad, pMyData, pMyData, frameCount);
+    ```
+
+If you need to change the values of the coefficients, but maintain the values in the registers you can do so with `ma_biquad_reinit()`. This is useful if you
+need to change the properties of the filter while keeping the values of registers valid to avoid glitching. Do not use `ma_biquad_init()` for this as it will
+do a full initialization which involves clearing the registers to 0. Note that changing the format or channel count after initialization is invalid and will
+result in an error.
+
+
+7.2. Low-Pass Filtering
+-----------------------
+Low-pass filtering is achieved with the following APIs:
+
+    +---------+------------------------------------------+
+    | API     | Description                              |
+    +---------+------------------------------------------+
+    | ma_lpf1 | First order low-pass filter              |
+    | ma_lpf2 | Second order low-pass filter             |
+    | ma_lpf  | High order low-pass filter (Butterworth) |
+    +---------+------------------------------------------+
+
+Low-pass filter example:
+
+    ```c
+    ma_lpf_config config = ma_lpf_config_init(ma_format_f32, channels, sampleRate, cutoffFrequency, order);
+    ma_result result = ma_lpf_init(&config, &lpf);
+    if (result != MA_SUCCESS) {
+        // Error.
+    }
+
+    ...
+
+    ma_lpf_process_pcm_frames(&lpf, pFramesOut, pFramesIn, frameCount);
+    ```
+
+Supported formats are `ma_format_s16` and` ma_format_f32`. If you need to use a different format you need to convert it yourself beforehand. Input and output
+frames are always interleaved.
+
+Filtering can be applied in-place by passing in the same pointer for both the input and output buffers, like so:
+
+    ```c
+    ma_lpf_process_pcm_frames(&lpf, pMyData, pMyData, frameCount);
+    ```
+
+The maximum filter order is limited to MA_MAX_FILTER_ORDER which is set to 8. If you need more, you can chain first and second order filters together.
+
+    ```c
+    for (iFilter = 0; iFilter < filterCount; iFilter += 1) {
+        ma_lpf2_process_pcm_frames(&lpf2[iFilter], pMyData, pMyData, frameCount);
+    }
+    ```
+
+If you need to change the configuration of the filter, but need to maintain the state of internal registers you can do so with `ma_lpf_reinit()`. This may be
+useful if you need to change the sample rate and/or cutoff frequency dynamically while maintaing smooth transitions. Note that changing the format or channel
+count after initialization is invalid and will result in an error.
+
+The `ma_lpf` object supports a configurable order, but if you only need a first order filter you may want to consider using `ma_lpf1`. Likewise, if you only
+need a second order filter you can use `ma_lpf2`. The advantage of this is that they're lighter weight and a bit more efficient.
+
+If an even filter order is specified, a series of second order filters will be processed in a chain. If an odd filter order is specified, a first order filter
+will be applied, followed by a series of second order filters in a chain.
+
+
+7.3. High-Pass Filtering
+------------------------
+High-pass filtering is achieved with the following APIs:
+
+    +---------+-------------------------------------------+
+    | API     | Description                               |
+    +---------+-------------------------------------------+
+    | ma_hpf1 | First order high-pass filter              |
+    | ma_hpf2 | Second order high-pass filter             |
+    | ma_hpf  | High order high-pass filter (Butterworth) |
+    +---------+-------------------------------------------+
+
+High-pass filters work exactly the same as low-pass filters, only the APIs are called `ma_hpf1`, `ma_hpf2` and `ma_hpf`. See example code for low-pass filters
+for example usage.
+
+
+7.4. Band-Pass Filtering
+------------------------
+Band-pass filtering is achieved with the following APIs:
+
+    +---------+-------------------------------+
+    | API     | Description                   |
+    +---------+-------------------------------+
+    | ma_bpf2 | Second order band-pass filter |
+    | ma_bpf  | High order band-pass filter   |
+    +---------+-------------------------------+
+
+Band-pass filters work exactly the same as low-pass filters, only the APIs are called `ma_bpf2` and `ma_hpf`. See example code for low-pass filters for example
+usage. Note that the order for band-pass filters must be an even number which means there is no first order band-pass filter, unlike low-pass and high-pass
+filters.
+
+
+7.5. Notch Filtering
+--------------------
+Notch filtering is achieved with the following APIs:
+
+    +-----------+------------------------------------------+
+    | API       | Description                              |
+    +-----------+------------------------------------------+
+    | ma_notch2 | Second order notching filter             |
+    +-----------+------------------------------------------+
+
+
+7.6. Peaking EQ Filtering
+-------------------------
+Peaking filtering is achieved with the following APIs:
+
+    +----------+------------------------------------------+
+    | API      | Description                              |
+    +----------+------------------------------------------+
+    | ma_peak2 | Second order peaking filter              |
+    +----------+------------------------------------------+
+
+
+7.7. Low Shelf Filtering
+------------------------
+Low shelf filtering is achieved with the following APIs:
+
+    +-------------+------------------------------------------+
+    | API         | Description                              |
+    +-------------+------------------------------------------+
+    | ma_loshelf2 | Second order low shelf filter            |
+    +-------------+------------------------------------------+
+
+Where a high-pass filter is used to eliminate lower frequencies, a low shelf filter can be used to just turn them down rather than eliminate them entirely.
+
+
+7.8. High Shelf Filtering
+-------------------------
+High shelf filtering is achieved with the following APIs:
+
+    +-------------+------------------------------------------+
+    | API         | Description                              |
+    +-------------+------------------------------------------+
+    | ma_hishelf2 | Second order high shelf filter           |
+    +-------------+------------------------------------------+
+
+The high shelf filter has the same API as the low shelf filter, only you would use `ma_hishelf` instead of `ma_loshelf`. Where a low shelf filter is used to
+adjust the volume of low frequencies, the high shelf filter does the same thing for high frequencies.
+
+
+
+
+8. Waveform and Noise Generation
+================================
+
+8.1. Waveforms
+--------------
+miniaudio supports generation of sine, square, triangle and sawtooth waveforms. This is achieved with the `ma_waveform` API. Example:
+
+    ```c
+    ma_waveform_config config = ma_waveform_config_init(
+        FORMAT,
+        CHANNELS,
+        SAMPLE_RATE,
+        ma_waveform_type_sine,
+        amplitude,
+        frequency);
+
+    ma_waveform waveform;
+    ma_result result = ma_waveform_init(&config, &waveform);
+    if (result != MA_SUCCESS) {
+        // Error.
+    }
+
+    ...
+
+    ma_waveform_read_pcm_frames(&waveform, pOutput, frameCount);
+    ```
+
+The amplitude, frequency and sample rate can be changed dynamically with `ma_waveform_set_amplitude()`, `ma_waveform_set_frequency()` and
+`ma_waveform_set_sample_rate()` respectively.
+
+You can invert the waveform by setting the amplitude to a negative value. You can use this to control whether or not a sawtooth has a positive or negative
+ramp, for example.
+
+Below are the supported waveform types:
+
+    +---------------------------+
+    | Enum Name                 |
+    +---------------------------+
+    | ma_waveform_type_sine     |
+    | ma_waveform_type_square   |
+    | ma_waveform_type_triangle |
+    | ma_waveform_type_sawtooth |
+    +---------------------------+
+
+
+
+8.2. Noise
+----------
+miniaudio supports generation of white, pink and Brownian noise via the `ma_noise` API. Example:
+
+    ```c
+    ma_noise_config config = ma_noise_config_init(
+        FORMAT,
+        CHANNELS,
+        ma_noise_type_white,
+        SEED,
+        amplitude);
+
+    ma_noise noise;
+    ma_result result = ma_noise_init(&config, &noise);
+    if (result != MA_SUCCESS) {
+        // Error.
+    }
+
+    ...
+
+    ma_noise_read_pcm_frames(&noise, pOutput, frameCount);
+    ```
+
+The noise API uses simple LCG random number generation. It supports a custom seed which is useful for things like automated testing requiring reproducibility.
+Setting the seed to zero will default to MA_DEFAULT_LCG_SEED.
+
+By default, the noise API will use different values for different channels. So, for example, the left side in a stereo stream will be different to the right
+side. To instead have each channel use the same random value, set the `duplicateChannels` member of the noise config to true, like so:
+
+    ```c
+    config.duplicateChannels = MA_TRUE;
+    ```
+
+Below are the supported noise types.
+
+    +------------------------+
+    | Enum Name              |
+    +------------------------+
+    | ma_noise_type_white    |
+    | ma_noise_type_pink     |
+    | ma_noise_type_brownian |

+9. Audio Buffers
+================
+miniaudio supports reading from a buffer of raw audio data via the `ma_audio_buffer` API. This can read from memory that's managed by the application, but
+can also handle the memory management for you internally. Memory management is flexible and should support most use cases.
+
+Audio buffers are initialised using the standard configuration system used everywhere in miniaudio:
+
+    ```c
+    ma_audio_buffer_config config = ma_audio_buffer_config_init(
+        format,
+        channels,
+        sizeInFrames,
+        pExistingData,
+        &allocationCallbacks);
+
+    ma_audio_buffer buffer;
+    result = ma_audio_buffer_init(&config, &buffer);
+    if (result != MA_SUCCESS) {
+        // Error.
+    }
+
+    ...
+
+    ma_audio_buffer_uninit(&buffer);
+    ```
+
+In the example above, the memory pointed to by `pExistingData` will _not_ be copied and is how an application can do self-managed memory allocation. If you
+would rather make a copy of the data, use `ma_audio_buffer_init_copy()`. To uninitialize the buffer, use `ma_audio_buffer_uninit()`.
+
+Sometimes it can be convenient to allocate the memory for the `ma_audio_buffer` structure _and_ the raw audio data in a contiguous block of memory. That is,
+the raw audio data will be located immediately after the `ma_audio_buffer` structure. To do this, use `ma_audio_buffer_alloc_and_init()`:
+
+    ```c
+    ma_audio_buffer_config config = ma_audio_buffer_config_init(
+        format,
+        channels,
+        sizeInFrames,
+        pExistingData,
+        &allocationCallbacks);
+
+    ma_audio_buffer* pBuffer
+    result = ma_audio_buffer_alloc_and_init(&config, &pBuffer);
+    if (result != MA_SUCCESS) {
+        // Error
+    }
+
+    ...
+    
+    ma_audio_buffer_uninit_and_free(&buffer);
+    ```
+
+If you initialize the buffer with `ma_audio_buffer_alloc_and_init()` you should uninitialize it with `ma_audio_buffer_uninit_and_free()`. In the example above,
+the memory pointed to by `pExistingData` will be copied into the buffer, which is contrary to the behavior of `ma_audio_buffer_init()`.
+
+An audio buffer has a playback cursor just like a decoder. As you read frames from the buffer, the cursor moves forward. The last parameter (`loop`) can be
+used to determine if the buffer should loop. The return value is the number of frames actually read. If this is less than the number of frames requested it
+means the end has been reached. This should never happen if the `loop` parameter is set to true. If you want to manually loop back to the start, you can do so
+with with `ma_audio_buffer_seek_to_pcm_frame(pAudioBuffer, 0)`. Below is an example for reading data from an audio buffer.
+
+    ```c
+    ma_uint64 framesRead = ma_audio_buffer_read_pcm_frames(pAudioBuffer, pFramesOut, desiredFrameCount, isLooping);
+    if (framesRead < desiredFrameCount) {
+        // If not looping, this means the end has been reached. This should never happen in looping mode with valid input.
+    }
+    ```
+
+Sometimes you may want to avoid the cost of data movement between the internal buffer and the output buffer. Instead you can use memory mapping to retrieve a
+pointer to a segment of data:
+
+    ```c
+    void* pMappedFrames;
+    ma_uint64 frameCount = frameCountToTryMapping;
+    ma_result result = ma_audio_buffer_map(pAudioBuffer, &pMappedFrames, &frameCount);
+    if (result == MA_SUCCESS) {
+        // Map was successful. The value in frameCount will be how many frames were _actually_ mapped, which may be
+        // less due to the end of the buffer being reached.
+        ma_copy_pcm_frames(pFramesOut, pMappedFrames, frameCount, pAudioBuffer->format, pAudioBuffer->channels);
+
+        // You must unmap the buffer.
+        ma_audio_buffer_unmap(pAudioBuffer, frameCount);
+    }
+    ```
+
+When you use memory mapping, the read cursor is increment by the frame count passed in to `ma_audio_buffer_unmap()`. If you decide not to process every frame
+you can pass in a value smaller than the value returned by `ma_audio_buffer_map()`. The disadvantage to using memory mapping is that it does not handle looping
+for you. You can determine if the buffer is at the end for the purpose of looping with `ma_audio_buffer_at_end()` or by inspecting the return value of
+`ma_audio_buffer_unmap()` and checking if it equals `MA_AT_END`. You should not treat `MA_AT_END` as an error when returned by `ma_audio_buffer_unmap()`.
+
+
+
+10. Ring Buffers
+================
+miniaudio supports lock free (single producer, single consumer) ring buffers which are exposed via the `ma_rb` and `ma_pcm_rb` APIs. The `ma_rb` API operates
+on bytes, whereas the `ma_pcm_rb` operates on PCM frames. They are otherwise identical as `ma_pcm_rb` is just a wrapper around `ma_rb`.
+
+Unlike most other APIs in miniaudio, ring buffers support both interleaved and deinterleaved streams. The caller can also allocate their own backing memory for
+the ring buffer to use internally for added flexibility. Otherwise the ring buffer will manage it's internal memory for you.
+
+The examples below use the PCM frame variant of the ring buffer since that's most likely the one you will want to use. To initialize a ring buffer, do
+something like the following:
+
+    ```c
+    ma_pcm_rb rb;
+    ma_result result = ma_pcm_rb_init(FORMAT, CHANNELS, BUFFER_SIZE_IN_FRAMES, NULL, NULL, &rb);
+    if (result != MA_SUCCESS) {
+        // Error
+    }
+    ```
+
+The `ma_pcm_rb_init()` function takes the sample format and channel count as parameters because it's the PCM varient of the ring buffer API. For the regular
+ring buffer that operates on bytes you would call `ma_rb_init()` which leaves these out and just takes the size of the buffer in bytes instead of frames. The
+fourth parameter is an optional pre-allocated buffer and the fifth parameter is a pointer to a `ma_allocation_callbacks` structure for custom memory allocation
+routines. Passing in `NULL` for this results in `MA_MALLOC()` and `MA_FREE()` being used.
+
+Use `ma_pcm_rb_init_ex()` if you need a deinterleaved buffer. The data for each sub-buffer is offset from each other based on the stride. To manage your
+sub-buffers you can use `ma_pcm_rb_get_subbuffer_stride()`, `ma_pcm_rb_get_subbuffer_offset()` and `ma_pcm_rb_get_subbuffer_ptr()`.
+
+Use 'ma_pcm_rb_acquire_read()` and `ma_pcm_rb_acquire_write()` to retrieve a pointer to a section of the ring buffer. You specify the number of frames you
+need, and on output it will set to what was actually acquired. If the read or write pointer is positioned such that the number of frames requested will require
+a loop, it will be clamped to the end of the buffer. Therefore, the number of frames you're given may be less than the number you requested.
+
+After calling `ma_pcm_rb_acquire_read()` or `ma_pcm_rb_acquire_write()`, you do your work on the buffer and then "commit" it with `ma_pcm_rb_commit_read()` or
+`ma_pcm_rb_commit_write()`. This is where the read/write pointers are updated. When you commit you need to pass in the buffer that was returned by the earlier
+call to `ma_pcm_rb_acquire_read()` or `ma_pcm_rb_acquire_write()` and is only used for validation. The number of frames passed to `ma_pcm_rb_commit_read()` and
+`ma_pcm_rb_commit_write()` is what's used to increment the pointers.
+
+If you want to correct for drift between the write pointer and the read pointer you can use a combination of `ma_pcm_rb_pointer_distance()`,
+`ma_pcm_rb_seek_read()` and `ma_pcm_rb_seek_write()`. Note that you can only move the pointers forward, and you should only move the read pointer forward via
+the consumer thread, and the write pointer forward by the producer thread. If there is too much space between the pointers, move the read pointer forward. If
+there is too little space between the pointers, move the write pointer forward.
+
+You can use a ring buffer at the byte level instead of the PCM frame level by using the `ma_rb` API. This is exactly the same, only you will use the `ma_rb`
+functions instead of `ma_pcm_rb` and instead of frame counts you will pass around byte counts.
+
+The maximum size of the buffer in bytes is `0x7FFFFFFF-(MA_SIMD_ALIGNMENT-1)` due to the most significant bit being used to encode a loop flag and the internally
+managed buffers always being aligned to MA_SIMD_ALIGNMENT.
+
+Note that the ring buffer is only thread safe when used by a single consumer thread and single producer thread.

+    +-------------+-----------------------+--------------------------------------------------------+
+
+Some backends have some nuance details you may want to be aware of.
+
+11.1. WASAPI
+------------
+- Low-latency shared mode will be disabled when using an application-defined sample rate which is different to the device's native sample rate. To work around
+  this, set `wasapi.noAutoConvertSRC` to true in the device config. This is due to IAudioClient3_InitializeSharedAudioStream() failing when the
+  `AUDCLNT_STREAMFLAGS_AUTOCONVERTPCM` flag is specified. Setting wasapi.noAutoConvertSRC will result in miniaudio's internal resampler being used instead
+  which will in turn enable the use of low-latency shared mode.
+
+11.2. PulseAudio
+----------------
+- If you experience bad glitching/noise on Arch Linux, consider this fix from the Arch wiki:
+  https://wiki.archlinux.org/index.php/PulseAudio/Troubleshooting#Glitches,_skips_or_crackling. Alternatively, consider using a different backend such as ALSA.
+
+11.3. Android
+-------------
+- To capture audio on Android, remember to add the RECORD_AUDIO permission to your manifest: `<uses-permission android:name="android.permission.RECORD_AUDIO" />`
+- With OpenSL|ES, only a single ma_context can be active at any given time. This is due to a limitation with OpenSL|ES.
+- With AAudio, only default devices are enumerated. This is due to AAudio not having an enumeration API (devices are enumerated through Java). You can however
+  perform your own device enumeration through Java and then set the ID in the ma_device_id structure (ma_device_id.aaudio) and pass it to ma_device_init().
+- The backend API will perform resampling where possible. The reason for this as opposed to using miniaudio's built-in resampler is to take advantage of any
+  potential device-specific optimizations the driver may implement.
+
+11.4. UWP
+---------
+- UWP only supports default playback and capture devices.
+- UWP requires the Microphone capability to be enabled in the application's manifest (Package.appxmanifest):
+
+    ```
+    <Package ...>
+        ...
+        <Capabilities>
+            <DeviceCapability Name="microphone" />
+        </Capabilities>
+    </Package>
+    ```
+
+11.5. Web Audio / Emscripten
+----------------------------
+- You cannot use `-std=c*` compiler flags, nor `-ansi`. This only applies to the Emscripten build.
+- The first time a context is initialized it will create a global object called "miniaudio" whose primary purpose is to act as a factory for device objects.
+- Currently the Web Audio backend uses ScriptProcessorNode's, but this may need to change later as they've been deprecated.
+- Google has implemented a policy in their browsers that prevent automatic media output without first receiving some kind of user input. The following web page
+  has additional details: https://developers.google.com/web/updates/2017/09/autoplay-policy-changes. Starting the device may fail if you try to start playback
+  without first handling some kind of user input.
+
+
+
+12. Miscellaneous Notes
+=======================
+- Automatic stream routing is enabled on a per-backend basis. Support is explicitly enabled for WASAPI and Core Audio, however other backends such as
+  PulseAudio may naturally support it, though not all have been tested.
+- The contents of the output buffer passed into the data callback will always be pre-initialized to zero unless the `noPreZeroedOutputBuffer` config variable
+  in `ma_device_config` is set to true, in which case it'll be undefined which will require you to write something to the entire buffer.
+- By default miniaudio will automatically clip samples. This only applies when the playback sample format is configured as `ma_format_f32`. If you are doing
+  clipping yourself, you can disable this overhead by setting `noClip` to true in the device config.
+- The sndio backend is currently only enabled on OpenBSD builds.
+- The audio(4) backend is supported on OpenBSD, but you may need to disable sndiod before you can use it.
+- Note that GCC and Clang requires `-msse2`, `-mavx2`, etc. for SIMD optimizations.
+- When compiling with VC6 and earlier, decoding is restricted to files less than 2GB in size. This is due to 64-bit file APIs not being available.

+Logging Levels
+==============
+A log level will automatically include the lower levels. For example, verbose logging will enable everything. The warning log level will only include warnings
+and errors, but will ignore informational and verbose logging. If you only want to handle a specific log level, implement a custom log callback (see
+ma_context_init() for details) and interrogate the `logLevel` parameter.
+
+By default the log level will be set to MA_LOG_LEVEL_ERROR, but you can change this by defining MA_LOG_LEVEL before the implementation of miniaudio.
+
+MA_LOG_LEVEL_VERBOSE
+    Mainly intended for debugging. This will enable all log levels and can be triggered from within the data callback so care must be taken when enabling this
+    in production environments.
+
+MA_LOG_LEVEL_INFO
+    Informational logging. Useful for debugging. This will also enable warning and error logs. This will never be called from within the data callback.
+
+MA_LOG_LEVEL_WARNING
+    Warnings. You should enable this in you development builds and action them when encounted. This will also enable error logs. These logs usually indicate a
+    potential problem or misconfiguration, but still allow you to keep running. This will never be called from within the data callback.
+
+MA_LOG_LEVEL_ERROR
+    Error logging. This will be fired when an operation fails and is subsequently aborted. This can be fired from within the data callback, in which case the
+    device will be stopped. You should always have this log level enabled.

+The callback for processing audio data from the device.
+
+The data callback is fired by miniaudio whenever the device needs to have more data delivered to a playback device, or when a capture device has some data
+available. This is called as soon as the backend asks for more data which means it may be called with inconsistent frame counts. You cannot assume the
+callback will be fired with a consistent frame count.
+
+
+Parameters
+----------
+pDevice (in)
+    A pointer to the relevant device.
+
+pOutput (out)
+    A pointer to the output buffer that will receive audio data that will later be played back through the speakers. This will be non-null for a playback or
+    full-duplex device and null for a capture and loopback device.
+
+pInput (in)
+    A pointer to the buffer containing input data from a recording device. This will be non-null for a capture, full-duplex or loopback device and null for a
+    playback device.
+
+frameCount (in)
+    The number of PCM frames to process. Note that this will not necessarily be equal to what you requested when you initialized the device. The
+    `periodSizeInFrames` and `periodSizeInMilliseconds` members of the device config are just hints, and are not necessarily exactly what you'll get. You must
+    not assume this will always be the same value each time the callback is fired.
+
+
+Remarks
+-------
+You cannot stop and start the device from inside the callback or else you'll get a deadlock. You must also not uninitialize the device from inside the
+callback. The following APIs cannot be called from inside the callback:
+
+    ma_device_init()
+    ma_device_init_ex()
+    ma_device_uninit()
+    ma_device_start()
+    ma_device_stop()
+
+The proper way to stop the device is to call `ma_device_stop()` from a different thread, normally the main application thread.

+    logCallback
+        Callback for handling log messages from miniaudio. 
+
+    threadPriority
+        The desired priority to use for the audio thread. Allowable values include the following:
+
+        |--------------------------------------|
+        | Thread Priority                      |

+        | ma_thread_priority_default           |
+        |--------------------------------------|
+
+    pUserData
+        A pointer to application-defined data. This can be accessed from the context object directly such as `context.pUserData`.
+
+    allocationCallbacks
+        Structure containing custom allocation callbacks. Leaving this at defaults will cause it to use MA_MALLOC, MA_REALLOC and MA_FREE. These allocation
+        callbacks will be used for anything tied to the context, including devices.
+
+    alsa.useVerboseDeviceEnumeration
+        ALSA will typically enumerate many different devices which can be intrusive and not user-friendly. To combat this, miniaudio will enumerate only unique
+        card/device pairs by default. The problem with this is that you lose a bit of flexibility and control. Setting alsa.useVerboseDeviceEnumeration makes
+        it so the ALSA backend includes all devices. Defaults to false.
+
+    pulse.pApplicationName
+        PulseAudio only. The application name to use when initializing the PulseAudio context with `pa_context_new()`.
+
+    pulse.pServerName
+        PulseAudio only. The name of the server to connect to with `pa_context_connect()`.
+
+    pulse.tryAutoSpawn
+        PulseAudio only. Whether or not to try automatically starting the PulseAudio daemon. Defaults to false. If you set this to true, keep in mind that
+        miniaudio uses a trial and error method to find the most appropriate backend, and this will result in the PulseAudio daemon starting which may be
+        intrusive for the end user.
+
+    coreaudio.sessionCategory
+        iOS only. The session category to use for the shared AudioSession instance. Below is a list of allowable values and their Core Audio equivalents.

+
+    jack.pClientName
+        The name of the client to pass to `jack_client_open()`.
+
+    jack.tryStartServer
+        Whether or not to try auto-starting the JACK server. Defaults to false.
+
+
+It is recommended that only a single context is active at any given time because it's a bulky data structure which performs run-time linking for the
+relevant backends every time it's initialized.
+
+The location of the context cannot change throughout it's lifetime. Consider allocating the `ma_context` object with `malloc()` if this is an issue. The
+reason for this is that a pointer to the context is stored in the `ma_device` structure.
+
+
+Example 1 - Default Initialization
+----------------------------------
+The example below shows how to initialize the context using the default configuration.
+
+```c
+ma_context context;
+ma_result result = ma_context_init(NULL, 0, NULL, &context);
+if (result != MA_SUCCESS) {
+    // Error.
+}
+```
+
+
+Example 2 - Custom Configuration
+--------------------------------
+The example below shows how to initialize the context using custom backend priorities and a custom configuration. In this hypothetical example, the program
+wants to prioritize ALSA over PulseAudio on Linux. They also want to avoid using the WinMM backend on Windows because it's latency is too high. They also
+want an error to be returned if no valid backend is available which they achieve by excluding the Null backend.
+
+For the configuration, the program wants to capture any log messages so they can, for example, route it to a log file and user interface.
+
+```c
+ma_backend backends[] = {
+    ma_backend_alsa,
+    ma_backend_pulseaudio,
+    ma_backend_wasapi,
+    ma_backend_dsound
+};
+
+ma_context_config config = ma_context_config_init();
+config.logCallback = my_log_callback;
+config.pUserData   = pMyUserData;
+
+ma_context context;
+ma_result result = ma_context_init(backends, sizeof(backends)/sizeof(backends[0]), &config, &context);
+if (result != MA_SUCCESS) {
+    // Error.
+    if (result == MA_NO_BACKEND) {
+        // Couldn't find an appropriate backend.
+    }
+}
+```

+Enumerates over every device (both playback and capture).
+
+This is a lower-level enumeration function to the easier to use `ma_context_get_devices()`. Use `ma_context_enumerate_devices()` if you would rather not incur
+an internal heap allocation, or it simply suits your code better.
+
+Note that this only retrieves the ID and name/description of the device. The reason for only retrieving basic information is that it would otherwise require
+opening the backend device in order to probe it for more detailed information which can be inefficient. Consider using `ma_context_get_device_info()` for this,
+but don't call it from within the enumeration callback.
+
+Returning false from the callback will stop enumeration. Returning true will continue enumeration.
+
+
+Parameters
+----------
+pContext (in)
+    A pointer to the context performing the enumeration.
+
+callback (in)
+    The callback to fire for each enumerated device.
+

+
+Return Value
+------------

+
+
+Thread Safety
+-------------

+
+
+Remarks
+-------
+Do _not_ assume the first enumerated device of a given type is the default device.
+
+Some backends and platforms may only support default playback and capture devices.
+
+In general, you should not do anything complicated from within the callback. In particular, do not try initializing a device from within the callback. Also,

+
+See `ma_device_init()` for details on specific configuration options.

+Example 1 - Simple Configuration
+--------------------------------
+The example below is what a program will typically want to configure for each device at a minimum. Notice how `ma_device_config_init()` is called first, and

+MA_API ma_device_config ma_device_config_init(ma_device_type deviceType);
+
+
+/*
+Initializes a device.
+
+A device represents a physical audio device. The idea is you send or receive audio data from the device to either play it back through a speaker, or capture it
+from a microphone. Whether or not you should send or receive data from the device (or both) depends on the type of device you are initializing which can be
+playback, capture, full-duplex or loopback. (Note that loopback mode is only supported on select backends.) Sending and receiving audio data to and from the
+device is done via a callback which is fired by miniaudio at periodic time intervals.
+
+The frequency at which data is delivered to and from a device depends on the size of it's period. The size of the period can be defined in terms of PCM frames
+or milliseconds, whichever is more convenient. Generally speaking, the smaller the period, the lower the latency at the expense of higher CPU usage and
+increased risk of glitching due to the more frequent and granular data deliver intervals. The size of a period will depend on your requirements, but
+miniaudio's defaults should work fine for most scenarios. If you're building a game you should leave this fairly small, whereas if you're building a simple
+media player you can make it larger. Note that the period size you request is actually just a hint - miniaudio will tell the backend what you want, but the
+backend is ultimately responsible for what it gives you. You cannot assume you will get exactly what you ask for.
+
+When delivering data to and from a device you need to make sure it's in the correct format which you can set through the device configuration. You just set the
+format that you want to use and miniaudio will perform all of the necessary conversion for you internally. When delivering data to and from the callback you
+can assume the format is the same as what you requested when you initialized the device. See Remarks for more details on miniaudio's data conversion pipeline.
+
+
+Parameters
+----------
+pContext (in, optional)
+    A pointer to the context that owns the device. This can be null, in which case it creates a default context internally.
+
+pConfig (in)
+    A pointer to the device configuration. Cannot be null. See remarks for details.
+
+pDevice (out)
+    A pointer to the device object being initialized.
+
+
+Return Value
+------------
+MA_SUCCESS if successful; any other error code otherwise.
+
+
+Thread Safety
+-------------
+Unsafe. It is not safe to call this function simultaneously for different devices because some backends depend on and mutate global state. The same applies to
+calling this at the same time as `ma_device_uninit()`.
+
+
+Callback Safety
+---------------
+Unsafe. It is not safe to call this inside any callback.
+
+
+Remarks
+-------
+Setting `pContext` to NULL will result in miniaudio creating a default context internally and is equivalent to passing in a context initialized like so:
+
+    ```c
+    ma_context_init(NULL, 0, NULL, &context);
+    ```
+
+Do not set `pContext` to NULL if you are needing to open multiple devices. You can, however, use NULL when initializing the first device, and then use
+device.pContext for the initialization of other devices.
+
+The device can be configured via the `pConfig` argument. The config object is initialized with `ma_device_config_init()`. Individual configuration settings can
+then be set directly on the structure. Below are the members of the `ma_device_config` object.
+
+    deviceType
+        Must be `ma_device_type_playback`, `ma_device_type_capture`, `ma_device_type_duplex` of `ma_device_type_loopback`.
+
+    sampleRate
+        The sample rate, in hertz. The most common sample rates are 48000 and 44100. Setting this to 0 will use the device's native sample rate.
+
+    periodSizeInFrames
+        The desired size of a period in PCM frames. If this is 0, `periodSizeInMilliseconds` will be used instead. If both are 0 the default buffer size will
+        be used depending on the selected performance profile. This value affects latency. See below for details.
+
+    periodSizeInMilliseconds
+        The desired size of a period in milliseconds. If this is 0, `periodSizeInFrames` will be used instead. If both are 0 the default buffer size will be
+        used depending on the selected performance profile. The value affects latency. See below for details.
+
+    periods
+        The number of periods making up the device's entire buffer. The total buffer size is `periodSizeInFrames` or `periodSizeInMilliseconds` multiplied by
+        this value. This is just a hint as backends will be the ones who ultimately decide how your periods will be configured.
+
+    performanceProfile
+        A hint to miniaudio as to the performance requirements of your program. Can be either `ma_performance_profile_low_latency` (default) or
+        `ma_performance_profile_conservative`. This mainly affects the size of default buffers and can usually be left at it's default value.
+
+    noPreZeroedOutputBuffer
+        When set to true, the contents of the output buffer passed into the data callback will be left undefined. When set to false (default), the contents of
+        the output buffer will be cleared the zero. You can use this to avoid the overhead of zeroing out the buffer if you can guarantee that your data
+        callback will write to every sample in the output buffer, or if you are doing your own clearing.
+
+    noClip
+        When set to true, the contents of the output buffer passed into the data callback will be clipped after returning. When set to false (default), the
+        contents of the output buffer are left alone after returning and it will be left up to the backend itself to decide whether or not the clip. This only
+        applies when the playback sample format is f32.
+
+    dataCallback
+        The callback to fire whenever data is ready to be delivered to or from the device.
+
+    stopCallback
+        The callback to fire whenever the device has stopped, either explicitly via `ma_device_stop()`, or implicitly due to things like the device being
+        disconnected.
+
+    pUserData
+        The user data pointer to use with the device. You can access this directly from the device object like `device.pUserData`.
+
+    resampling.algorithm
+        The resampling algorithm to use when miniaudio needs to perform resampling between the rate specified by `sampleRate` and the device's native rate. The
+        default value is `ma_resample_algorithm_linear`, and the quality can be configured with `resampling.linear.lpfOrder`.
+
+    resampling.linear.lpfOrder
+        The linear resampler applies a low-pass filter as part of it's procesing for anti-aliasing. This setting controls the order of the filter. The higher
+        the value, the better the quality, in general. Setting this to 0 will disable low-pass filtering altogether. The maximum value is
+        `MA_MAX_FILTER_ORDER`. The default value is `min(4, MA_MAX_FILTER_ORDER)`.
+
+    playback.pDeviceID
+        A pointer to a `ma_device_id` structure containing the ID of the playback device to initialize. Setting this NULL (default) will use the system's
+        default playback device. Retrieve the device ID from the `ma_device_info` structure, which can be retrieved using device enumeration.
+
+    playback.format
+        The sample format to use for playback. When set to `ma_format_unknown` the device's native format will be used. This can be retrieved after
+        initialization from the device object directly with `device.playback.format`.
+
+    playback.channels
+        The number of channels to use for playback. When set to 0 the device's native channel count will be used. This can be retrieved after initialization
+        from the device object directly with `device.playback.channels`.
+
+    playback.channelMap
+        The channel map to use for playback. When left empty, the device's native channel map will be used. This can be retrieved after initialization from the
+        device object direct with `device.playback.channelMap`.
+
+    playback.shareMode
+        The preferred share mode to use for playback. Can be either `ma_share_mode_shared` (default) or `ma_share_mode_exclusive`. Note that if you specify
+        exclusive mode, but it's not supported by the backend, initialization will fail. You can then fall back to shared mode if desired by changing this to
+        ma_share_mode_shared and reinitializing.
+
+    capture.pDeviceID
+        A pointer to a `ma_device_id` structure containing the ID of the capture device to initialize. Setting this NULL (default) will use the system's
+        default capture device. Retrieve the device ID from the `ma_device_info` structure, which can be retrieved using device enumeration.
+
+    capture.format
+        The sample format to use for capture. When set to `ma_format_unknown` the device's native format will be used. This can be retrieved after
+        initialization from the device object directly with `device.capture.format`.
+
+    capture.channels
+        The number of channels to use for capture. When set to 0 the device's native channel count will be used. This can be retrieved after initialization
+        from the device object directly with `device.capture.channels`.
+
+    capture.channelMap
+        The channel map to use for capture. When left empty, the device's native channel map will be used. This can be retrieved after initialization from the
+        device object direct with `device.capture.channelMap`.
+
+    capture.shareMode
+        The preferred share mode to use for capture. Can be either `ma_share_mode_shared` (default) or `ma_share_mode_exclusive`. Note that if you specify
+        exclusive mode, but it's not supported by the backend, initialization will fail. You can then fall back to shared mode if desired by changing this to
+        ma_share_mode_shared and reinitializing.
+
+    wasapi.noAutoConvertSRC
+        WASAPI only. When set to true, disables WASAPI's automatic resampling and forces the use of miniaudio's resampler. Defaults to false. 
+
+    wasapi.noDefaultQualitySRC
+        WASAPI only. Only used when `wasapi.noAutoConvertSRC` is set to false. When set to true, disables the use of `AUDCLNT_STREAMFLAGS_SRC_DEFAULT_QUALITY`.
+        You should usually leave this set to false, which is the default.
+
+    wasapi.noAutoStreamRouting
+        WASAPI only. When set to true, disables automatic stream routing on the WASAPI backend. Defaults to false.
+
+    wasapi.noHardwareOffloading
+        WASAPI only. When set to true, disables the use of WASAPI's hardware offloading feature. Defaults to false.
+
+    alsa.noMMap
+        ALSA only. When set to true, disables MMap mode. Defaults to false.
+
+    alsa.noAutoFormat
+        ALSA only. When set to true, disables ALSA's automatic format conversion by including the SND_PCM_NO_AUTO_FORMAT flag. Defaults to false.
+
+    alsa.noAutoChannels
+        ALSA only. When set to true, disables ALSA's automatic channel conversion by including the SND_PCM_NO_AUTO_CHANNELS flag. Defaults to false.
+
+    alsa.noAutoResample
+        ALSA only. When set to true, disables ALSA's automatic resampling by including the SND_PCM_NO_AUTO_RESAMPLE flag. Defaults to false.
+
+    pulse.pStreamNamePlayback
+        PulseAudio only. Sets the stream name for playback.
+
+    pulse.pStreamNameCapture
+        PulseAudio only. Sets the stream name for capture.
+
+
+Once initialized, the device's config is immutable. If you need to change the config you will need to initialize a new device.
+
+After initializing the device it will be in a stopped state. To start it, use `ma_device_start()`.
+
+If both `periodSizeInFrames` and `periodSizeInMilliseconds` are set to zero, it will default to `MA_DEFAULT_PERIOD_SIZE_IN_MILLISECONDS_LOW_LATENCY` or
+`MA_DEFAULT_PERIOD_SIZE_IN_MILLISECONDS_CONSERVATIVE`, depending on whether or not `performanceProfile` is set to `ma_performance_profile_low_latency` or
+`ma_performance_profile_conservative`.
+
+If you request exclusive mode and the backend does not support it an error will be returned. For robustness, you may want to first try initializing the device
+in exclusive mode, and then fall back to shared mode if required. Alternatively you can just request shared mode (the default if you leave it unset in the
+config) which is the most reliable option. Some backends do not have a practical way of choosing whether or not the device should be exclusive or not (ALSA,
+for example) in which case it just acts as a hint. Unless you have special requirements you should try avoiding exclusive mode as it's intrusive to the user.
+Starting with Windows 10, miniaudio will use low-latency shared mode where possible which may make exclusive mode unnecessary.
+
+When sending or receiving data to/from a device, miniaudio will internally perform a format conversion to convert between the format specified by the config
+and the format used internally by the backend. If you pass in 0 for the sample format, channel count, sample rate _and_ channel map, data transmission will run
+on an optimized pass-through fast path. You can retrieve the format, channel count and sample rate by inspecting the `playback/capture.format`,
+`playback/capture.channels` and `sampleRate` members of the device object.
+
+When compiling for UWP you must ensure you call this function on the main UI thread because the operating system may need to present the user with a message
+asking for permissions. Please refer to the official documentation for ActivateAudioInterfaceAsync() for more information.
+
+ALSA Specific: When initializing the default device, requesting shared mode will try using the "dmix" device for playback and the "dsnoop" device for capture.
+If these fail it will try falling back to the "hw" device.
+
+
+Example 1 - Simple Initialization
+---------------------------------
+This example shows how to initialize a simple playback device using a standard configuration. If you are just needing to do simple playback from the default
+playback device this is usually all you need.
+
+```c
+ma_device_config config = ma_device_config_init(ma_device_type_playback);
+config.playback.format   = ma_format_f32;
+config.playback.channels = 2;
+config.sampleRate        = 48000;
+config.dataCallback      = ma_data_callback;
+config.pMyUserData       = pMyUserData;
+
+ma_device device;
+ma_result result = ma_device_init(NULL, &config, &device);
+if (result != MA_SUCCESS) {
+    // Error
+}
+```
+
+
+Example 2 - Advanced Initialization
+-----------------------------------
+This example shows how you might do some more advanced initialization. In this hypothetical example we want to control the latency by setting the buffer size
+and period count. We also want to allow the user to be able to choose which device to output from which means we need a context so we can perform device
+enumeration.
+
+```c
+ma_context context;
+ma_result result = ma_context_init(NULL, 0, NULL, &context);
+if (result != MA_SUCCESS) {
+    // Error
+}
+
+ma_device_info* pPlaybackDeviceInfos;
+ma_uint32 playbackDeviceCount;
+result = ma_context_get_devices(&context, &pPlaybackDeviceInfos, &playbackDeviceCount, NULL, NULL);
+if (result != MA_SUCCESS) {
+    // Error
+}
+
+// ... choose a device from pPlaybackDeviceInfos ...
+
+ma_device_config config = ma_device_config_init(ma_device_type_playback);
+config.playback.pDeviceID       = pMyChosenDeviceID;    // <-- Get this from the `id` member of one of the `ma_device_info` objects returned by ma_context_get_devices().
+config.playback.format          = ma_format_f32;
+config.playback.channels        = 2;
+config.sampleRate               = 48000;
+config.dataCallback             = ma_data_callback;
+config.pUserData                = pMyUserData;
+config.periodSizeInMilliseconds = 10;

+
+ma_device device;
+result = ma_device_init(&context, &config, &device);

+
+
+Remarks
+-------
+For a playback device, this will retrieve an initial chunk of audio data from the client before returning. The reason for this is to ensure there is valid
+audio data in the buffer, which needs to be done before the device begins playback.
+
+This API waits until the backend device has been started for real by the worker thread. It also waits on a mutex for thread-safety.
+
+Do not call this in any callback.

+Callback Safety

+Unsafe. It is not safe to call this inside any callback. Doing this will result in a deadlock.
+
+
+Remarks
+-------
+This API needs to wait on the worker thread to stop the backend device properly before returning. It also waits on a mutex for thread-safety. In addition, some
+backends need to wait for the device to finish playback/recording of the current fragment which can take some time (usually proportionate to the buffer size
+that was specified at initialization time).
+
+Backends are required to either pause the stream in-place or drain the buffer if pausing is not possible. The reason for this is that stopping the device and
+the resuming it with ma_device_start() (which you might do when your program loses focus) may result in a situation where those samples are never output to the
+speakers or received from the microphone which can in turn result in de-syncs.
+
+Do not call this in any callback.
+
+This will be called implicitly by `ma_device_uninit()`.

+        problems with some device configurations when used in conjunction with MMAP access mode. To fix this problem we need to disable
+        resampling.
+        
+        To reproduce this problem, open the "plug:dmix" device, and set the sample rate to 44100. Internally, it looks like dmix uses a
+        sample rate of 48000. The hardware parameters will get set correctly with no errors, but it looks like the 44100 -> 48000 resampling
+        doesn't work properly - but only with MMAP access mode. You will notice skipping/crackling in the audio, and it'll run at a slightly
+        faster rate.
+        
+        miniaudio has built-in support for sample rate conversion (albeit low quality at the moment), so disabling resampling should be fine
+        for us. The only problem is that it won't be taking advantage of any kind of hardware-accelerated resampling and it won't be very
+        good quality until I get a chance to improve the quality of miniaudio's software sample rate conversion.
+        
+        I don't currently know if the dmix plugin is the only one with this error. Indeed, this is the only one I've been able to reproduce
+        this error with. In the future, we may want to restrict the disabling of resampling to only known bad plugins.

+Core Audio
+
+So far, Core Audio has been the worst backend to work with due to being both unintuitive and having almost no documentation
+apart from comments in the headers (which admittedly are quite good). For my own purposes, and for anybody out there whose
+needing to figure out how this darn thing works, I'm going to outline a few things here.
+
+Since miniaudio is a fairly low-level API, one of the things it needs is control over specific devices, and it needs to be
+able to identify whether or not it can be used as playback and/or capture. The AudioObject API is the only one I've seen
+that supports this level of detail. There was some public domain sample code I stumbled across that used the AudioComponent
+and AudioUnit APIs, but I couldn't see anything that gave low-level control over device selection and capabilities (the
+distinction between playback and capture in particular). Therefore, miniaudio is using the AudioObject API.
+
+Most (all?) functions in the AudioObject API take a AudioObjectID as it's input. This is the device identifier. When
+retrieving global information, such as the device list, you use kAudioObjectSystemObject. When retrieving device-specific
+data, you pass in the ID for that device. In order to retrieve device-specific IDs you need to enumerate over each of the
+devices. This is done using the AudioObjectGetPropertyDataSize() and AudioObjectGetPropertyData() APIs which seem to be
+the central APIs for retrieving information about the system and specific devices.
+
+To use the AudioObjectGetPropertyData() API you need to use the notion of a property address. A property address is a
+structure with three variables and is used to identify which property you are getting or setting. The first is the "selector"
+which is basically the specific property that you're wanting to retrieve or set. The second is the "scope", which is
+typically set to kAudioObjectPropertyScopeGlobal, kAudioObjectPropertyScopeInput for input-specific properties and
+kAudioObjectPropertyScopeOutput for output-specific properties. The last is the "element" which is always set to
+kAudioObjectPropertyElementMaster in miniaudio's case. I don't know of any cases where this would be set to anything different.
+
+Back to the earlier issue of device retrieval, you first use the AudioObjectGetPropertyDataSize() API to retrieve the size
+of the raw data which is just a list of AudioDeviceID's. You use the kAudioObjectSystemObject AudioObjectID, and a property
+address with the kAudioHardwarePropertyDevices selector and the kAudioObjectPropertyScopeGlobal scope. Once you have the
+size, allocate a block of memory of that size and then call AudioObjectGetPropertyData(). The data is just a list of
+AudioDeviceID's so just do "dataSize/sizeof(AudioDeviceID)" to know the device count.

+        something called AudioWorklets which _forces_ you to load a _separate_ .js file at run time... nice... Hopefully ScriptProcessorNode will continue to
+        work for years to come, but this may need to change to use AudioSourceBufferNode instead, which I think is what Emscripten uses for it's built-in SDL
+        implementation. I'll be avoiding that insane AudioWorklet API like the plague...
+
+        For capture it is a bit unintuitive. We use the ScriptProccessorNode _only_ to get the raw PCM data. It is connected to an AudioContext just like the
+        playback case, however we just output silence to the AudioContext instead of passing any real data. It would make more sense to me to use the
+        MediaRecorder API, but unfortunately you need to specify a MIME time (Opus, Vorbis, etc.) for the binary blob that's returned to the client, but I've
+        been unable to figure out how to get this as raw PCM. The closest I can think is to use the MIME type for WAV files and just parse it, but I don't know
+        how well this would work. Although ScriptProccessorNode is deprecated, in practice it seems to have pretty good browser support so I'm leaving it like
+        this for now. If anyone knows how I could get raw PCM data using the MediaRecorder API please let me know!

+    Imagine the following simplified example: You have a single input speaker which is the front/left speaker which you want to convert to
+    the following output configuration:
+    
+     - front/left
+     - side/left
+     - back/left
+    
+    The front/left output is easy - it the same speaker position so it receives the full contribution of the front/left input. The amount
+    of contribution to apply to the side/left and back/left speakers, however, is a bit more complicated.
+    
+    Imagine the front/left speaker as emitting audio from two planes - the front plane and the left plane. You can think of the front/left
+    speaker emitting half of it's total volume from the front, and the other half from the left. Since part of it's volume is being emitted
+    from the left side, and the side/left and back/left channels also emit audio from the left plane, one would expect that they would
+    receive some amount of contribution from front/left speaker. The amount of contribution depends on how many planes are shared between
+    the two speakers. Note that in the examples below I've added a top/front/left speaker as an example just to show how the math works
+    across 3 spatial dimensions.
+    
+    The first thing to do is figure out how each speaker's volume is spread over each of plane:
+     - front/left:     2 planes (front and left)      = 1/2 = half it's total volume on each plane
+     - side/left:      1 plane (left only)            = 1/1 = entire volume from left plane
+     - back/left:      2 planes (back and left)       = 1/2 = half it's total volume on each plane
+     - top/front/left: 3 planes (top, front and left) = 1/3 = one third it's total volume on each plane
+    
+    The amount of volume each channel contributes to each of it's planes is what controls how much it is willing to given and take to other
+    channels on the same plane. The volume that is willing to the given by one channel is multiplied by the volume that is willing to be
+    taken by the other to produce the final contribution.

+RELEASE NOTES - VERSION 0.10.x
+==============================
+Version 0.10 includes major API changes and refactoring, mostly concerned with the data conversion system. Data conversion is performed internally to convert
+audio data between the format requested when initializing the `ma_device` object and the format of the internal device used by the backend. The same applies
+to the `ma_decoder` object. The previous design has several design flaws and missing features which necessitated a complete redesign.
+
+
+Changes to Data Conversion
+--------------------------
+The previous data conversion system used callbacks to deliver input data for conversion. This design works well in some specific situations, but in other
+situations it has some major readability and maintenance issues. The decision was made to replace this with a more iterative approach where you just pass in a
+pointer to the input data directly rather than dealing with a callback.
+
+The following are the data conversion APIs that have been removed and their replacements:
+
+  - ma_format_converter -> ma_convert_pcm_frames_format()
+  - ma_channel_router   -> ma_channel_converter
+  - ma_src              -> ma_resampler
+  - ma_pcm_converter    -> ma_data_converter
+
+The previous conversion APIs accepted a callback in their configs. There are no longer any callbacks to deal with. Instead you just pass the data into the
+`*_process_pcm_frames()` function as a pointer to a buffer.
+
+The simplest aspect of data conversion is sample format conversion. To convert between two formats, just call `ma_convert_pcm_frames_format()`. Channel
+conversion is also simple which you can do with `ma_channel_converter` via `ma_channel_converter_process_pcm_frames()`.
+
+Resampling is more complicated because the number of output frames that are processed is different to the number of input frames that are consumed. When you
+call `ma_resampler_process_pcm_frames()` you need to pass in the number of input frames available for processing and the number of output frames you want to
+output. Upon returning they will receive the number of input frames that were consumed and the number of output frames that were generated.
+
+The `ma_data_converter` API is a wrapper around format, channel and sample rate conversion and handles all of the data conversion you'll need which probably
+makes it the best option if you need to do data conversion.
+
+In addition to changes to the API design, a few other changes have been made to the data conversion pipeline:
+
+  - The sinc resampler has been removed. This was completely broken and never actually worked properly.
+  - The linear resampler now uses low-pass filtering to remove aliasing. The quality of the low-pass filter can be controlled via the resampler config with the
+    `lpfOrder` option, which has a maximum value of MA_MAX_FILTER_ORDER.
+  - Data conversion now supports s16 natively which runs through a fixed point pipeline. Previously everything needed to be converted to floating point before
+    processing, whereas now both s16 and f32 are natively supported. Other formats still require conversion to either s16 or f32 prior to processing, however
+    `ma_data_converter` will handle this for you.
+
+
+Custom Memory Allocators
+------------------------
+miniaudio has always supported macro level customization for memory allocation via MA_MALLOC, MA_REALLOC and MA_FREE, however some scenarios require more
+flexibility by allowing a user data pointer to be passed to the custom allocation routines. Support for this has been added to version 0.10 via the
+`ma_allocation_callbacks` structure. Anything making use of heap allocations has been updated to accept this new structure.
+
+The `ma_context_config` structure has been updated with a new member called `allocationCallbacks`. Leaving this set to it's defaults returned by
+`ma_context_config_init()` will cause it to use MA_MALLOC, MA_REALLOC and MA_FREE. Likewise, The `ma_decoder_config` structure has been updated in the same
+way, and leaving everything as-is after `ma_decoder_config_init()` will cause it to use the same defaults.
+
+The following APIs have been updated to take a pointer to a `ma_allocation_callbacks` object. Setting this parameter to NULL will cause it to use defaults.
+Otherwise they will use the relevant callback in the structure.
+
+  - ma_malloc()
+  - ma_realloc()
+  - ma_free()
+  - ma_aligned_malloc()
+  - ma_aligned_free()
+  - ma_rb_init() / ma_rb_init_ex()
+  - ma_pcm_rb_init() / ma_pcm_rb_init_ex()
+
+Note that you can continue to use MA_MALLOC, MA_REALLOC and MA_FREE as per normal. These will continue to be used by default if you do not specify custom
+allocation callbacks.
+
+
+Buffer and Period Configuration Changes
+---------------------------------------
+The way in which the size of the internal buffer and periods are specified in the device configuration have changed. In previous versions, the config variables
+`bufferSizeInFrames` and `bufferSizeInMilliseconds` defined the size of the entire buffer, with the size of a period being the size of this variable divided by
+the period count. This became confusing because people would expect the value of `bufferSizeInFrames` or `bufferSizeInMilliseconds` to independantly determine
+latency, when in fact it was that value divided by the period count that determined it. These variables have been removed and replaced with new ones called
+`periodSizeInFrames` and `periodSizeInMilliseconds`.
+
+These new configuration variables work in the same way as their predecessors in that if one is set to 0, the other will be used, but the main difference is
+that you now set these to you desired latency rather than the size of the entire buffer. The benefit of this is that it's much easier and less confusing to
+configure latency.
+
+The following unused APIs have been removed:
+
+    ma_get_default_buffer_size_in_milliseconds()
+    ma_get_default_buffer_size_in_frames()
+
+The following macros have been removed:
+
+    MA_BASE_BUFFER_SIZE_IN_MILLISECONDS_LOW_LATENCY
+    MA_BASE_BUFFER_SIZE_IN_MILLISECONDS_CONSERVATIVE
+
+
+Other API Changes
+-----------------
+Other less major API changes have also been made in version 0.10.
+
+`ma_device_set_stop_callback()` has been removed. If you require a stop callback, you must now set it via the device config just like the data callback.
+
+The `ma_sine_wave` API has been replaced with a more general API called `ma_waveform`. This supports generation of different types of waveforms, including
+sine, square, triangle and sawtooth. Use `ma_waveform_init()` in place of `ma_sine_wave_init()` to initialize the waveform object. This takes a configuration
+object called `ma_waveform_config` which defines the properties of the waveform. Use `ma_waveform_config_init()` to initialize a `ma_waveform_config` object.
+Use `ma_waveform_read_pcm_frames()` in place of `ma_sine_wave_read_f32()` and `ma_sine_wave_read_f32_ex()`.
+
+`ma_convert_frames()` and `ma_convert_frames_ex()` have been changed. Both of these functions now take a new parameter called `frameCountOut` which specifies
+the size of the output buffer in PCM frames. This has been added for safety. In addition to this, the parameters for `ma_convert_frames_ex()` have changed to
+take a pointer to a `ma_data_converter_config` object to specify the input and output formats to convert between. This was done to make it more flexible, to
+prevent the parameter list getting too long, and to prevent API breakage whenever a new conversion property is added.
+
+`ma_calculate_frame_count_after_src()` has been renamed to `ma_calculate_frame_count_after_resampling()` for consistency with the new `ma_resampler` API.
+
+
+Filters
+-------
+The following filters have been added:
+
+    |-------------|-------------------------------------------------------------------|
+    | API         | Description                                                       |
+    |-------------|-------------------------------------------------------------------|
+    | ma_biquad   | Biquad filter (transposed direct form 2)                          |
+    | ma_lpf1     | First order low-pass filter                                       |
+    | ma_lpf2     | Second order low-pass filter                                      |
+    | ma_lpf      | High order low-pass filter (Butterworth)                          |
+    | ma_hpf1     | First order high-pass filter                                      |
+    | ma_hpf2     | Second order high-pass filter                                     |
+    | ma_hpf      | High order high-pass filter (Butterworth)                         |
+    | ma_bpf2     | Second order band-pass filter                                     |
+    | ma_bpf      | High order band-pass filter                                       |
+    | ma_peak2    | Second order peaking filter                                       |
+    | ma_notch2   | Second order notching filter                                      |
+    | ma_loshelf2 | Second order low shelf filter                                     |
+    | ma_hishelf2 | Second order high shelf filter                                    |
+    |-------------|-------------------------------------------------------------------|
+
+These filters all support 32-bit floating point and 16-bit signed integer formats natively. Other formats need to be converted beforehand.
+
+
+Sine, Square, Triangle and Sawtooth Waveforms
+---------------------------------------------
+Previously miniaudio supported only sine wave generation. This has now been generalized to support sine, square, triangle and sawtooth waveforms. The old
+`ma_sine_wave` API has been removed and replaced with the `ma_waveform` API. Use `ma_waveform_config_init()` to initialize a config object, and then pass it
+into `ma_waveform_init()`. Then use `ma_waveform_read_pcm_frames()` to read PCM data.
+
+
+Noise Generation
+----------------
+A noise generation API has been added. This is used via the `ma_noise` API. Currently white, pink and Brownian noise is supported. The `ma_noise` API is
+similar to the waveform API. Use `ma_noise_config_init()` to initialize a config object, and then pass it into `ma_noise_init()` to initialize a `ma_noise`
+object. Then use `ma_noise_read_pcm_frames()` to read PCM data.
+
+
+Miscellaneous Changes
+---------------------
+The MA_NO_STDIO option has been removed. This would disable file I/O APIs, however this has proven to be too hard to maintain for it's perceived value and was
+therefore removed.
+
+Internal functions have all been made static where possible. If you get warnings about unused functions, please submit a bug report.
+
+The `ma_device` structure is no longer defined as being aligned to MA_SIMD_ALIGNMENT. This resulted in a possible crash when allocating a `ma_device` object on
+the heap, but not aligning it to MA_SIMD_ALIGNMENT. This crash would happen due to the compiler seeing the alignment specified on the structure and assuming it
+was always aligned as such and thinking it was safe to emit alignment-dependant SIMD instructions. Since miniaudio's philosophy is for things to just work,
+this has been removed from all structures.
+
+Results codes have been overhauled. Unnecessary result codes have been removed, and some have been renumbered for organisation purposes. If you are are binding
+maintainer you will need to update your result codes. Support has also been added for retrieving a human readable description of a given result code via the
+`ma_result_description()` API.
+
+ALSA: The automatic format conversion, channel conversion and resampling performed by ALSA is now disabled by default as they were causing some compatibility
+issues with certain devices and configurations. These can be individually enabled via the device config:
+
+    ```c
+    deviceConfig.alsa.noAutoFormat   = MA_TRUE;
+    deviceConfig.alsa.noAutoChannels = MA_TRUE;
+    deviceConfig.alsa.noAutoResample = MA_TRUE;
+    ```

+RELEASE NOTES - VERSION 0.9.x
+=============================
+Version 0.9 includes major API changes, centered mostly around full-duplex and the rebrand to "miniaudio". Before I go into detail about the major changes I
+would like to apologize. I know it's annoying dealing with breaking API changes, but I think it's best to get these changes out of the way now while the
+library is still relatively young and unknown.
+
+There's been a lot of refactoring with this release so there's a good chance a few bugs have been introduced. I apologize in advance for this. You may want to
+hold off on upgrading for the short term if you're worried. If mini_al v0.8.14 works for you, and you don't need full-duplex support, you can avoid upgrading
+(though you won't be getting future bug fixes).
+
+
+Rebranding to "miniaudio"
+-------------------------
+The decision was made to rename mini_al to miniaudio. Don't worry, it's the same project. The reason for this is simple:
+
+1) Having the word "audio" in the title makes it immediately clear that the library is related to audio; and
+2) I don't like the look of the underscore.
+
+This rebrand has necessitated a change in namespace from "mal" to "ma". I know this is annoying, and I apologize, but it's better to get this out of the road
+now rather than later. Also, since there are necessary API changes for full-duplex support I think it's better to just get the namespace change over and done
+with at the same time as the full-duplex changes. I'm hoping this will be the last of the major API changes. Fingers crossed!
+
+The implementation define is now "#define MINIAUDIO_IMPLEMENTATION". You can also use "#define MA_IMPLEMENTATION" if that's your preference.
+
+
+Full-Duplex Support
+-------------------
+The major feature added to version 0.9 is full-duplex. This has necessitated a few API changes.
+
+1) The data callback has now changed. Previously there was one type of callback for playback and another for capture. I wanted to avoid a third callback just
+   for full-duplex so the decision was made to break this API and unify the callbacks. Now, there is just one callback which is the same for all three modes
+   (playback, capture, duplex). The new callback looks like the following:
+
+       void data_callback(ma_device* pDevice, void* pOutput, const void* pInput, ma_uint32 frameCount);
+
+   This callback allows you to move data straight out of the input buffer and into the output buffer in full-duplex mode. In playback-only mode, pInput will be
+   null. Likewise, pOutput will be null in capture-only mode. The sample count is no longer returned from the callback since it's not necessary for miniaudio
+   anymore.
+
+2) The device config needed to change in order to support full-duplex. Full-duplex requires the ability to allow the client to choose a different PCM format
+   for the playback and capture sides. The old ma_device_config object simply did not allow this and needed to change. With these changes you now specify the
+   device ID, format, channels, channel map and share mode on a per-playback and per-capture basis (see example below). The sample rate must be the same for
+   playback and capture.
+
+   Since the device config API has changed I have also decided to take the opportunity to simplify device initialization. Now, the device ID, device type and
+   callback user data are set in the config. ma_device_init() is now simplified down to taking just the context, device config and a pointer to the device
+   object being initialized. The rationale for this change is that it just makes more sense to me that these are set as part of the config like everything
+   else.
+
+   Example device initialization:
+
+       ma_device_config config = ma_device_config_init(ma_device_type_duplex);   // Or ma_device_type_playback or ma_device_type_capture.
+       config.playback.pDeviceID = &myPlaybackDeviceID; // Or NULL for the default playback device.
+       config.playback.format    = ma_format_f32;
+       config.playback.channels  = 2;
+       config.capture.pDeviceID  = &myCaptureDeviceID;  // Or NULL for the default capture device.
+       config.capture.format     = ma_format_s16;
+       config.capture.channels   = 1;
+       config.sampleRate         = 44100;
+       config.dataCallback       = data_callback;
+       config.pUserData          = &myUserData;
+
+       result = ma_device_init(&myContext, &config, &device);
+       if (result != MA_SUCCESS) {
+           ... handle error ...
+       }
+
+   Note that the "onDataCallback" member of ma_device_config has been renamed to "dataCallback". Also, "onStopCallback" has been renamed to "stopCallback".
+
+This is the first pass for full-duplex and there is a known bug. You will hear crackling on the following backends when sample rate conversion is required for
+the playback device:
+  - Core Audio
+  - JACK
+  - AAudio
+  - OpenSL
+  - WebAudio
+
+In addition to the above, not all platforms have been absolutely thoroughly tested simply because I lack the hardware for such thorough testing. If you
+experience a bug, an issue report on GitHub or an email would be greatly appreciated (and a sample program that reproduces the issue if possible).
+
+
+Other API Changes
+-----------------
+In addition to the above, the following API changes have been made:
+
+- The log callback is no longer passed to ma_context_config_init(). Instead you need to set it manually after initialization.
+- The onLogCallback member of ma_context_config has been renamed to "logCallback".
+- The log callback now takes a logLevel parameter. The new callback looks like: void log_callback(ma_context* pContext, ma_device* pDevice, ma_uint32 logLevel, const char* message)
+  - You can use ma_log_level_to_string() to convert the logLevel to human readable text if you want to log it.
+- Some APIs have been renamed:
+  - mal_decoder_read()          -> ma_decoder_read_pcm_frames()
+  - mal_decoder_seek_to_frame() -> ma_decoder_seek_to_pcm_frame()
+  - mal_sine_wave_read()        -> ma_sine_wave_read_f32()
+  - mal_sine_wave_read_ex()     -> ma_sine_wave_read_f32_ex()
+- Some APIs have been removed:
+  - mal_device_get_buffer_size_in_bytes()
+  - mal_device_set_recv_callback()
+  - mal_device_set_send_callback()
+  - mal_src_set_input_sample_rate()
+  - mal_src_set_output_sample_rate()
+- Error codes have been rearranged. If you're a binding maintainer you will need to update.
+- The ma_backend enums have been rearranged to priority order. The rationale for this is to simplify automatic backend selection and to make it easier to see
+  the priority. If you're a binding maintainer you will need to update.
+- ma_dsp has been renamed to ma_pcm_converter. The rationale for this change is that I'm expecting "ma_dsp" to conflict with some future planned high-level
+  APIs.
+- For functions that take a pointer/count combo, such as ma_decoder_read_pcm_frames(), the parameter order has changed so that the pointer comes before the
+  count. The rationale for this is to keep it consistent with things like memcpy().
+
+
+Miscellaneous Changes
+---------------------
+The following miscellaneous changes have also been made.
+
+- The AAudio backend has been added for Android 8 and above. This is Android's new "High-Performance Audio" API. (For the record, this is one of the nicest
+  audio APIs out there, just behind the BSD audio APIs).
+- The WebAudio backend has been added. This is based on ScriptProcessorNode. This removes the need for SDL.
+- The SDL and OpenAL backends have been removed. These were originally implemented to add support for platforms for which miniaudio was not explicitly
+  supported. These are no longer needed and have therefore been removed.
+- Device initialization now fails if the requested share mode is not supported. If you ask for exclusive mode, you either get an exclusive mode device, or an
+  error. The rationale for this change is to give the client more control over how to handle cases when the desired shared mode is unavailable.
+- A lock-free ring buffer API has been added. There are two varients of this. "ma_rb" operates on bytes, whereas "ma_pcm_rb" operates on PCM frames.
+- The library is now licensed as a choice of Public Domain (Unlicense) _or_ MIT-0 (No Attribution) which is the same as MIT, but removes the attribution
+  requirement. The rationale for this is to support countries that don't recognize public domain.

+  - Change ma_data_source_seek_pcm_frames() to return a result code and output the frames seeked as an output parameter.
+  - Change ma_audio_buffer_unmap() to return MA_AT_END when the end has been reached. This should be considered successful.
+  - Change playback.pDeviceID and capture.pDeviceID to constant pointers in ma_device_config.
+  - Add support for initializing decoders from a virtual file system object. This is achieved via the ma_vfs API and allows the application to customize file
+    IO for the loading and reading of raw audio data. Passing in NULL for the VFS will use defaults. New APIs:
+    - ma_decoder_init_vfs()
+    - ma_decoder_init_vfs_wav()
+    - ma_decoder_init_vfs_flac()
+    - ma_decoder_init_vfs_mp3()

+  - Add documentation for log levels.
+  - The ma_event API has been made public in preparation for some uncoming work.
+  - Fix a bug in ma_decoder_seek_to_pcm_frame() where the internal sample rate is not being taken into account for determining the seek location.
+  - Fix some bugs with the linear resampler when dynamically changing the sample rate.
+  - Fix compilation errors with MA_NO_DEVICE_IO.
+  - Fix some warnings with GCC and -std=c89.
+  - Fix some formatting warnings with GCC and -Wall and -Wpedantic.
+  - Fix some warnings with VC6.
+  - Minor optimization to ma_copy_pcm_frames(). This is now a no-op when the input and output buffers are the same.
+
+v0.10.7 - 2020-05-25
+  - Fix a compilation error in the C++ build.
+  - Silence a warning.
+
+v0.10.6 - 2020-05-24
+  - Change ma_clip_samples_f32() and ma_clip_pcm_frames_f32() to take a 64-bit sample/frame count.
+  - Change ma_zero_pcm_frames() to clear to 128 for ma_format_u8.
+  - Add ma_silence_pcm_frames() which replaces ma_zero_pcm_frames(). ma_zero_pcm_frames() will be removed in version 0.11.
+  - Add support for u8, s24 and s32 formats to ma_channel_converter.
+  - Add compile-time and run-time version querying.
+    - MA_VERSION_MINOR

+    - ma_version()
+    - ma_version_string()
+  - Add ma_audio_buffer for reading raw audio data directly from memory.
+  - Fix a bug in shuffle mode in ma_channel_converter.
+  - Fix compilation errors in certain configurations for ALSA and PulseAudio.
+  - The data callback now initializes the output buffer to 128 when the playback sample format is ma_format_u8.
+
+v0.10.5 - 2020-05-05
+  - Change ma_zero_pcm_frames() to take a 64-bit frame count.
+  - Add ma_copy_pcm_frames().
+  - Add MA_NO_GENERATION build option to exclude the `ma_waveform` and `ma_noise` APIs from the build.
+  - Add support for formatted logging to the VC6 build.
+  - Fix a crash in the linear resampler when LPF order is 0.
+  - Fix compilation errors and warnings with older versions of Visual Studio.
+  - Minor documentation updates.
+
+v0.10.4 - 2020-04-12

+
+v0.10.3 - 2020-04-07
+  - Bring up to date with breaking changes to dr_mp3.
+  - Remove MA_NO_STDIO. This was causing compilation errors and the maintenance cost versus practical benefit is no longer worthwhile.
+  - Fix a bug with data conversion where it was unnecessarily converting to s16 or f32 and then straight back to the original format.
+  - Fix compilation errors and warnings with Visual Studio 2005.
+  - ALSA: Disable ALSA's automatic data conversion by default and add configuration options to the device config:
+    - alsa.noAutoFormat
+    - alsa.noAutoChannels
+    - alsa.noAutoResample
+  - WASAPI: Add some overrun recovery for ma_device_type_capture devices.
+
+v0.10.2 - 2020-03-22
+  - Decorate some APIs with MA_API which were missed in the previous version.
+  - Fix a bug in ma_linear_resampler_set_rate() and ma_linear_resampler_set_rate_ratio().
+
+v0.10.1 - 2020-03-17

+  - Fix a bug where opening a file would return a success code when in fact it failed.
+  - Fix compilation errors with Visual Studio 6 and 2003.
+  - Fix warnings on macOS.
+
+v0.10.0 - 2020-03-07
+  - API CHANGE: Refactor data conversion APIs
+    - ma_format_converter has been removed. Use ma_convert_pcm_frames_format() instead.
+    - ma_channel_router has been replaced with ma_channel_converter.
+    - ma_src has been replaced with ma_resampler
+    - ma_pcm_converter has been replaced with ma_data_converter
+  - API CHANGE: Add support for custom memory allocation callbacks. The following APIs have been updated to take an extra parameter for the allocation
+    callbacks:
+    - ma_malloc()
+    - ma_realloc()
+    - ma_free()
+    - ma_aligned_malloc()
+    - ma_aligned_free()
+    - ma_rb_init() / ma_rb_init_ex()
+    - ma_pcm_rb_init() / ma_pcm_rb_init_ex()
+  - API CHANGE: Simplify latency specification in device configurations. The bufferSizeInFrames and bufferSizeInMilliseconds parameters have been replaced with
+    periodSizeInFrames and periodSizeInMilliseconds respectively. The previous variables defined the size of the entire buffer, whereas the new ones define the
+    size of a period. The following APIs have been removed since they are no longer relevant:
+    - ma_get_default_buffer_size_in_milliseconds()
+    - ma_get_default_buffer_size_in_frames()
+  - API CHANGE: ma_device_set_stop_callback() has been removed. If you require a stop callback, you must now set it via the device config just like the data
+    callback.
+  - API CHANGE: The ma_sine_wave API has been replaced with ma_waveform. The following APIs have been removed:
+    - ma_sine_wave_init()
+    - ma_sine_wave_read_f32()
+    - ma_sine_wave_read_f32_ex()
+  - API CHANGE: ma_convert_frames() has been updated to take an extra parameter which is the size of the output buffer in PCM frames. Parameters have also been
+    reordered.
+  - API CHANGE: ma_convert_frames_ex() has been changed to take a pointer to a ma_data_converter_config object to specify the input and output formats to
+    convert between.
+  - API CHANGE: ma_calculate_frame_count_after_src() has been renamed to ma_calculate_frame_count_after_resampling().
+  - Add support for the following filters:
+    - Biquad (ma_biquad)
+    - First order low-pass (ma_lpf1)
+    - Second order low-pass (ma_lpf2)
+    - Low-pass with configurable order (ma_lpf)
+    - First order high-pass (ma_hpf1)
+    - Second order high-pass (ma_hpf2)
+    - High-pass with configurable order (ma_hpf)
+    - Second order band-pass (ma_bpf2)
+    - Band-pass with configurable order (ma_bpf)
+    - Second order peaking EQ (ma_peak2)
+    - Second order notching (ma_notch2)
+    - Second order low shelf (ma_loshelf2)
+    - Second order high shelf (ma_hishelf2)
+  - Add waveform generation API (ma_waveform) with support for the following:
+    - Sine
+    - Square
+    - Triangle
+    - Sawtooth
+  - Add noise generation API (ma_noise) with support for the following:
+    - White
+    - Pink
+    - Brownian
+  - Add encoding API (ma_encoder). This only supports outputting to WAV files via dr_wav.
+  - Add ma_result_description() which is used to retrieve a human readable description of a given result code.
+  - Result codes have been changed. Binding maintainers will need to update their result code constants.
+  - More meaningful result codes are now returned when a file fails to open.
+  - Internal functions have all been made static where possible.
+  - Fix potential crash when ma_device object's are not aligned to MA_SIMD_ALIGNMENT.
+  - Fix a bug in ma_decoder_get_length_in_pcm_frames() where it was returning the length based on the internal sample rate rather than the output sample rate.
+  - Fix bugs in some backends where the device is not drained properly in ma_device_stop().
+  - Improvements to documentation.
+
+v0.9.10 - 2020-01-15
+  - Fix compilation errors due to #if/#endif mismatches.
+  - WASAPI: Fix a bug where automatic stream routing is being performed for devices that are initialized with an explicit device ID.
+  - iOS: Fix a crash on device uninitialization.
+
+v0.9.9 - 2020-01-09
+  - Fix compilation errors with MinGW.
+  - Fix compilation errors when compiling on Apple platforms.
+  - WASAPI: Add support for disabling hardware offloading.
+  - WASAPI: Add support for disabling automatic stream routing.
+  - Core Audio: Fix bugs in the case where the internal device uses deinterleaved buffers.
+  - Core Audio: Add support for controlling the session category (AVAudioSessionCategory) and options (AVAudioSessionCategoryOptions).
+  - JACK: Fix bug where incorrect ports are connected.
+
+v0.9.8 - 2019-10-07
+  - WASAPI: Fix a potential deadlock when starting a full-duplex device.
+  - WASAPI: Enable automatic resampling by default. Disable with config.wasapi.noAutoConvertSRC.
+  - Core Audio: Fix bugs with automatic stream routing.
+  - Add support for controlling whether or not the content of the output buffer passed in to the data callback is pre-initialized
+    to zero. By default it will be initialized to zero, but this can be changed by setting noPreZeroedOutputBuffer in the device
+    config. Setting noPreZeroedOutputBuffer to true will leave the contents undefined.
+  - Add support for clipping samples after the data callback has returned. This only applies when the playback sample format is
+    configured as ma_format_f32. If you are doing clipping yourself, you can disable this overhead by setting noClip to true in
+    the device config.
+  - Add support for master volume control for devices.
+    - Use ma_device_set_master_volume() to set the volume to a factor between 0 and 1, where 0 is silence and 1 is full volume.
+    - Use ma_device_set_master_gain_db() to set the volume in decibels where 0 is full volume and < 0 reduces the volume.
+  - Fix warnings emitted by GCC when `__inline__` is undefined or defined as nothing.
+
+v0.9.7 - 2019-08-28
+  - Add support for loopback mode (WASAPI only).
+    - To use this, set the device type to ma_device_type_loopback, and then fill out the capture section of the device config.
+    - If you need to capture from a specific output device, set the capture device ID to that of a playback device.
+  - Fix a crash when an error is posted in ma_device_init().
+  - Fix a compilation error when compiling for ARM architectures.
+  - Fix a bug with the audio(4) backend where the device is incorrectly being opened in non-blocking mode.

+
+v0.9.6 - 2019-08-04
+  - Add support for loading decoders using a wchar_t string for file paths.
+  - Don't trigger an assert when ma_device_start() is called on a device that is already started. This will now log a warning
+    and return MA_INVALID_OPERATION. The same applies for ma_device_stop().
+  - Try fixing an issue with PulseAudio taking a long time to start playback.
+  - Fix a bug in ma_convert_frames() and ma_convert_frames_ex().
+  - Fix memory leaks in the WASAPI backend.
+  - Fix a compilation error with Visual Studio 2010.
+
+v0.9.5 - 2019-05-21
+  - Add logging to ma_dlopen() and ma_dlsym().
+  - Add ma_decoder_get_length_in_pcm_frames().
+  - Fix a bug with capture on the OpenSL|ES backend.
+  - Fix a bug with the ALSA backend where a device would not restart after being stopped.
+
+v0.9.4 - 2019-05-06
+  - Add support for C89. With this change, miniaudio should compile clean with GCC/Clang with "-std=c89 -ansi -pedantic" and
+    Microsoft compilers back to VC6. Other compilers should also work, but have not been tested.
+
+v0.9.3 - 2019-04-19
+  - Fix compiler errors on GCC when compiling with -std=c99.
+
+v0.9.2 - 2019-04-08
+  - Add support for per-context user data.
+  - Fix a potential bug with context configs.
+  - Fix some bugs with PulseAudio.
+
+v0.9.1 - 2019-03-17
+  - Fix a bug where the output buffer is not getting zeroed out before calling the data callback. This happens when
+    the device is running in passthrough mode (not doing any data conversion).
+  - Fix an issue where the data callback is getting called too frequently on the WASAPI and DirectSound backends.
+  - Fix error on the UWP build.
+  - Fix a build error on Apple platforms.
+
+v0.9 - 2019-03-06
+  - Rebranded to "miniaudio". All namespaces have been renamed from "mal" to "ma".
+  - API CHANGE: ma_device_init() and ma_device_config_init() have changed significantly:
+    - The device type, device ID and user data pointer have moved from ma_device_init() to the config.
+    - All variations of ma_device_config_init_*() have been removed in favor of just ma_device_config_init().
+    - ma_device_config_init() now takes only one parameter which is the device type. All other properties need
+      to be set on the returned object directly.
+    - The onDataCallback and onStopCallback members of ma_device_config have been renamed to "dataCallback"
+      and "stopCallback".
+    - The ID of the physical device is now split into two: one for the playback device and the other for the
+      capture device. This is required for full-duplex. These are named "pPlaybackDeviceID" and "pCaptureDeviceID".
+  - API CHANGE: The data callback has changed. It now uses a unified callback for all device types rather than
+    being separate for each. It now takes two pointers - one containing input data and the other output data. This
+    design in required for full-duplex. The return value is now void instead of the number of frames written. The
+    new callback looks like the following:
+        void data_callback(ma_device* pDevice, void* pOutput, const void* pInput, ma_uint32 frameCount);
+  - API CHANGE: Remove the log callback parameter from ma_context_config_init(). With this change,
+    ma_context_config_init() now takes no parameters and the log callback is set via the structure directly. The
+    new policy for config initialization is that only mandatory settings are passed in to *_config_init(). The
+    "onLog" member of ma_context_config has been renamed to "logCallback".
+  - API CHANGE: Remove ma_device_get_buffer_size_in_bytes().
+  - API CHANGE: Rename decoding APIs to "pcm_frames" convention.
+    - mal_decoder_read()          -> ma_decoder_read_pcm_frames()
+    - mal_decoder_seek_to_frame() -> ma_decoder_seek_to_pcm_frame()
+  - API CHANGE: Rename sine wave reading APIs to f32 convention.
+    - mal_sine_wave_read()    -> ma_sine_wave_read_f32()
+    - mal_sine_wave_read_ex() -> ma_sine_wave_read_f32_ex()
+  - API CHANGE: Remove some deprecated APIs
+    - mal_device_set_recv_callback()
+    - mal_device_set_send_callback()
+    - mal_src_set_input_sample_rate()
+    - mal_src_set_output_sample_rate()
+  - API CHANGE: Add log level to the log callback. New signature:
+    - void on_log(ma_context* pContext, ma_device* pDevice, ma_uint32 logLevel, const char* message)
+  - API CHANGE: Changes to result codes. Constants have changed and unused codes have been removed. If you're
+    a binding mainainer you will need to update your result code constants.
+  - API CHANGE: Change the order of the ma_backend enums to priority order. If you are a binding maintainer, you
+    will need to update.
+  - API CHANGE: Rename mal_dsp to ma_pcm_converter. All functions have been renamed from mal_dsp_*() to
+    ma_pcm_converter_*(). All structures have been renamed from mal_dsp* to ma_pcm_converter*.
+  - API CHANGE: Reorder parameters of ma_decoder_read_pcm_frames() to be consistent with the new parameter order scheme.
+  - The resampling algorithm has been changed from sinc to linear. The rationale for this is that the sinc implementation
+    is too inefficient right now. This will hopefully be improved at a later date.
+  - Device initialization will no longer fall back to shared mode if exclusive mode is requested but is unusable.
+    With this change, if you request an device in exclusive mode, but exclusive mode is not supported, it will not
+    automatically fall back to shared mode. The client will need to reinitialize the device in shared mode if that's
+    what they want.
+  - Add ring buffer API. This is ma_rb and ma_pcm_rb, the difference being that ma_rb operates on bytes and
+    ma_pcm_rb operates on PCM frames.
+  - Add Web Audio backend. This is used when compiling with Emscripten. The SDL backend, which was previously
+    used for web support, will be removed in a future version.
+  - Add AAudio backend (Android Audio). This is the new priority backend for Android. Support for AAudio starts
+    with Android 8. OpenSL|ES is used as a fallback for older versions of Android.
+  - Remove OpenAL and SDL backends.
+  - Fix a possible deadlock when rapidly stopping the device after it has started.
+  - Update documentation.
+  - Change licensing to a choice of public domain _or_ MIT-0 (No Attribution).
+
+v0.8.14 - 2018-12-16
+  - Core Audio: Fix a bug where the device state is not set correctly after stopping.
+  - Add support for custom weights to the channel router.
+  - Update decoders to use updated APIs in dr_flac, dr_mp3 and dr_wav.
+
+v0.8.13 - 2018-12-04
+  - Core Audio: Fix a bug with channel mapping.
+  - Fix a bug with channel routing where the back/left and back/right channels have the wrong weight.
+
+v0.8.12 - 2018-11-27
+  - Drop support for SDL 1.2. The Emscripten build now requires "-s USE_SDL=2".
+  - Fix a linking error with ALSA.
+  - Fix a bug on iOS where the device name is not set correctly.
+
+v0.8.11 - 2018-11-21
+  - iOS bug fixes.
+  - Minor tweaks to PulseAudio.
+
+v0.8.10 - 2018-10-21
+  - Core Audio: Fix a hang when uninitializing a device.
+  - Fix a bug where an incorrect value is returned from mal_device_stop().
+
+v0.8.9 - 2018-09-28
+  - Fix a bug with the SDL backend where device initialization fails.
+
+v0.8.8 - 2018-09-14
+  - Fix Linux build with the ALSA backend.
+  - Minor documentation fix.
+
+v0.8.7 - 2018-09-12
+  - Fix a bug with UWP detection.
+
+v0.8.6 - 2018-08-26
+  - Automatically switch the internal device when the default device is unplugged. Note that this is still in the
+    early stages and not all backends handle this the same way. As of this version, this will not detect a default
+    device switch when changed from the operating system's audio preferences (unless the backend itself handles
+    this automatically). This is not supported in exclusive mode.
+  - WASAPI and Core Audio: Add support for stream routing. When the application is using a default device and the
+    user switches the default device via the operating system's audio preferences, miniaudio will automatically switch
+    the internal device to the new default. This is not supported in exclusive mode.
+  - WASAPI: Add support for hardware offloading via IAudioClient2. Only supported on Windows 8 and newer.
+  - WASAPI: Add support for low-latency shared mode via IAudioClient3. Only supported on Windows 10 and newer.
+  - Add support for compiling the UWP build as C.
+  - mal_device_set_recv_callback() and mal_device_set_send_callback() have been deprecated. You must now set this
+    when the device is initialized with mal_device_init*(). These will be removed in version 0.9.0.
+
+v0.8.5 - 2018-08-12
+  - Add support for specifying the size of a device's buffer in milliseconds. You can still set the buffer size in
+    frames if that suits you. When bufferSizeInFrames is 0, bufferSizeInMilliseconds will be used. If both are non-0
+    then bufferSizeInFrames will take priority. If both are set to 0 the default buffer size is used.
+  - Add support for the audio(4) backend to OpenBSD.
+  - Fix a bug with the ALSA backend that was causing problems on Raspberry Pi. This significantly improves the
+    Raspberry Pi experience.
+  - Fix a bug where an incorrect number of samples is returned from sinc resampling.
+  - Add support for setting the value to be passed to internal calls to CoInitializeEx().
+  - WASAPI and WinMM: Stop the device when it is unplugged.
+
+v0.8.4 - 2018-08-06
+  - Add sndio backend for OpenBSD.
+  - Add audio(4) backend for NetBSD.
+  - Drop support for the OSS backend on everything except FreeBSD and DragonFly BSD.
+  - Formats are now native-endian (were previously little-endian).
+  - Mark some APIs as deprecated:
+    - mal_src_set_input_sample_rate() and mal_src_set_output_sample_rate() are replaced with mal_src_set_sample_rate().
+    - mal_dsp_set_input_sample_rate() and mal_dsp_set_output_sample_rate() are replaced with mal_dsp_set_sample_rate().
+  - Fix a bug when capturing using the WASAPI backend.
+  - Fix some aliasing issues with resampling, specifically when increasing the sample rate.
+  - Fix warnings.
+
+v0.8.3 - 2018-07-15
+  - Fix a crackling bug when resampling in capture mode.
+  - Core Audio: Fix a bug where capture does not work.
+  - ALSA: Fix a bug where the worker thread can get stuck in an infinite loop.
+  - PulseAudio: Fix a bug where mal_context_init() succeeds when PulseAudio is unusable.
+  - JACK: Fix a bug where mal_context_init() succeeds when JACK is unusable.
+
+v0.8.2 - 2018-07-07
+  - Fix a bug on macOS with Core Audio where the internal callback is not called.
+
+v0.8.1 - 2018-07-06
+  - Fix compilation errors and warnings.
+
+v0.8 - 2018-07-05
+  - Changed MAL_IMPLEMENTATION to MINI_AL_IMPLEMENTATION for consistency with other libraries. The old
+    way is still supported for now, but you should update as it may be removed in the future.
+  - API CHANGE: Replace device enumeration APIs. mal_enumerate_devices() has been replaced with
+    mal_context_get_devices(). An additional low-level device enumration API has been introduced called
+    mal_context_enumerate_devices() which uses a callback to report devices.
+  - API CHANGE: Rename mal_get_sample_size_in_bytes() to mal_get_bytes_per_sample() and add
+    mal_get_bytes_per_frame().
+  - API CHANGE: Replace mal_device_config.preferExclusiveMode with mal_device_config.shareMode.
+    - This new config can be set to mal_share_mode_shared (default) or mal_share_mode_exclusive.
+  - API CHANGE: Remove excludeNullDevice from mal_context_config.alsa.
+  - API CHANGE: Rename MAL_MAX_SAMPLE_SIZE_IN_BYTES to MAL_MAX_PCM_SAMPLE_SIZE_IN_BYTES.
+  - API CHANGE: Change the default channel mapping to the standard Microsoft mapping.
+  - API CHANGE: Remove backend-specific result codes.
+  - API CHANGE: Changes to the format conversion APIs (mal_pcm_f32_to_s16(), etc.)
+  - Add support for Core Audio (Apple).
+  - Add support for PulseAudio.
+    - This is the highest priority backend on Linux (higher priority than ALSA) since it is commonly
+      installed by default on many of the popular distros and offer's more seamless integration on
+      platforms where PulseAudio is used. In addition, if PulseAudio is installed and running (which
+      is extremely common), it's better to just use PulseAudio directly rather than going through the
+      "pulse" ALSA plugin (which is what the "default" ALSA device is likely set to).
+  - Add support for JACK.
+  - Remove dependency on asound.h for the ALSA backend. This means the ALSA development packages are no
+    longer required to build miniaudio.
+  - Remove dependency on dsound.h for the DirectSound backend. This fixes build issues with some
+    distributions of MinGW.
+  - Remove dependency on audioclient.h for the WASAPI backend. This fixes build issues with some
+    distributions of MinGW.
+  - Add support for dithering to format conversion.
+  - Add support for configuring the priority of the worker thread.
+  - Add a sine wave generator.
+  - Improve efficiency of sample rate conversion.
+  - Introduce the notion of standard channel maps. Use mal_get_standard_channel_map().
+  - Introduce the notion of default device configurations. A default config uses the same configuration
+    as the backend's internal device, and as such results in a pass-through data transmission pipeline.
+  - Add support for passing in NULL for the device config in mal_device_init(), which uses a default
+    config. This requires manually calling mal_device_set_send/recv_callback().
+  - Add support for decoding from raw PCM data (mal_decoder_init_raw(), etc.)
+  - Make mal_device_init_ex() more robust.
+  - Make some APIs more const-correct.
+  - Fix errors with SDL detection on Apple platforms.
+  - Fix errors with OpenAL detection.
+  - Fix some memory leaks.
+  - Fix a bug with opening decoders from memory.
+  - Early work on SSE2, AVX2 and NEON optimizations.
+  - Miscellaneous bug fixes.
+  - Documentation updates.
+
+v0.7 - 2018-02-25
+  - API CHANGE: Change mal_src_read_frames() and mal_dsp_read_frames() to use 64-bit sample counts.
+  - Add decoder APIs for loading WAV, FLAC, Vorbis and MP3 files.
+  - Allow opening of devices without a context.
+    - In this case the context is created and managed internally by the device.
+  - Change the default channel mapping to the same as that used by FLAC.
+  - Fix build errors with macOS.
+
+v0.6c - 2018-02-12
+  - Fix build errors with BSD/OSS.
+
+v0.6b - 2018-02-03
+  - Fix some warnings when compiling with Visual C++.
+
+v0.6a - 2018-01-26
+  - Fix errors with channel mixing when increasing the channel count.
+  - Improvements to the build system for the OpenAL backend.
+  - Documentation fixes.
+
+v0.6 - 2017-12-08
+  - API CHANGE: Expose and improve mutex APIs. If you were using the mutex APIs before this version you'll
+    need to update.
+  - API CHANGE: SRC and DSP callbacks now take a pointer to a mal_src and mal_dsp object respectively.
+  - API CHANGE: Improvements to event and thread APIs. These changes make these APIs more consistent.
+  - Add support for SDL and Emscripten.
+  - Simplify the build system further for when development packages for various backends are not installed.
+    With this change, when the compiler supports __has_include, backends without the relevant development
+    packages installed will be ignored. This fixes the build for old versions of MinGW.
+  - Fixes to the Android build.
+  - Add mal_convert_frames(). This is a high-level helper API for performing a one-time, bulk conversion of
+    audio data to a different format.
+  - Improvements to f32 -> u8/s16/s24/s32 conversion routines.
+  - Fix a bug where the wrong value is returned from mal_device_start() for the OpenSL backend.
+  - Fixes and improvements for Raspberry Pi.
+  - Warning fixes.
+
+v0.5 - 2017-11-11
+  - API CHANGE: The mal_context_init() function now takes a pointer to a mal_context_config object for
+    configuring the context. The works in the same kind of way as the device config. The rationale for this
+    change is to give applications better control over context-level properties, add support for backend-
+    specific configurations, and support extensibility without breaking the API.
+  - API CHANGE: The alsa.preferPlugHW device config variable has been removed since it's not really useful for
+    anything anymore.
+  - ALSA: By default, device enumeration will now only enumerate over unique card/device pairs. Applications
+    can enable verbose device enumeration by setting the alsa.useVerboseDeviceEnumeration context config
+    variable.
+  - ALSA: When opening a device in shared mode (the default), the dmix/dsnoop plugin will be prioritized. If
+    this fails it will fall back to the hw plugin. With this change the preferExclusiveMode config is now
+    honored. Note that this does not happen when alsa.useVerboseDeviceEnumeration is set to true (see above)
+    which is by design.
+  - ALSA: Add support for excluding the "null" device using the alsa.excludeNullDevice context config variable.
+  - ALSA: Fix a bug with channel mapping which causes an assertion to fail.
+  - Fix errors with enumeration when pInfo is set to NULL.
+  - OSS: Fix a bug when starting a device when the client sends 0 samples for the initial buffer fill.
+
+v0.4 - 2017-11-05
+  - API CHANGE: The log callback is now per-context rather than per-device and as is thus now passed to
+    mal_context_init(). The rationale for this change is that it allows applications to capture diagnostic
+    messages at the context level. Previously this was only available at the device level.
+  - API CHANGE: The device config passed to mal_device_init() is now const.
+  - Added support for OSS which enables support on BSD platforms.
+  - Added support for WinMM (waveOut/waveIn).
+  - Added support for UWP (Universal Windows Platform) applications. Currently C++ only.
+  - Added support for exclusive mode for selected backends. Currently supported on WASAPI.
+  - POSIX builds no longer require explicit linking to libpthread (-lpthread).
+  - ALSA: Explicit linking to libasound (-lasound) is no longer required.
+  - ALSA: Latency improvements.
+  - ALSA: Use MMAP mode where available. This can be disabled with the alsa.noMMap config.
+  - ALSA: Use "hw" devices instead of "plughw" devices by default. This can be disabled with the
+    alsa.preferPlugHW config.
+  - WASAPI is now the highest priority backend on Windows platforms.
+  - Fixed an error with sample rate conversion which was causing crackling when capturing.
+  - Improved error handling.
+  - Improved compiler support.
+  - Miscellaneous bug fixes.
+
+v0.3 - 2017-06-19
+  - API CHANGE: Introduced the notion of a context. The context is the highest level object and is required for
+    enumerating and creating devices. Now, applications must first create a context, and then use that to
+    enumerate and create devices. The reason for this change is to ensure device enumeration and creation is
+    tied to the same backend. In addition, some backends are better suited to this design.
+  - API CHANGE: Removed the rewinding APIs because they're too inconsistent across the different backends, hard
+    to test and maintain, and just generally unreliable.
+  - Added helper APIs for initializing mal_device_config objects.
+  - Null Backend: Fixed a crash when recording.
+  - Fixed build for UWP.
+  - Added support for f32 formats to the OpenSL|ES backend.
+  - Added initial implementation of the WASAPI backend.
+  - Added initial implementation of the OpenAL backend.
+  - Added support for low quality linear sample rate conversion.
+  - Added early support for basic channel mapping.
+
+v0.2 - 2016-10-28
+  - API CHANGE: Add user data pointer as the last parameter to mal_device_init(). The rationale for this
+    change is to ensure the logging callback has access to the user data during initialization.
+  - API CHANGE: Have device configuration properties be passed to mal_device_init() via a structure. Rationale:
+    1) The number of parameters is just getting too much.
+    2) It makes it a bit easier to add new configuration properties in the future. In particular, there's a
+       chance there will be support added for backend-specific properties.
+  - Dropped support for f64, A-law and Mu-law formats since they just aren't common enough to justify the
+    added maintenance cost.
+  - DirectSound: Increased the default buffer size for capture devices.
+  - Added initial implementation of the OpenSL|ES backend.
+
+v0.1 - 2016-10-21
+  - Initial versioned release.

+#define STBI_INCLUDE_STB_IMAGE_H
+
+// DOCUMENTATION
+//
+// Limitations:
+//    - no 12-bit-per-channel JPEG
+//    - no JPEGs with arithmetic coding
+//    - GIF always returns *comp=4
+//
+// Basic usage (see HDR discussion below for HDR usage):
+//    int x,y,n;
+//    unsigned char *data = stbi_load(filename, &x, &y, &n, 0);
+//    // ... process data if not NULL ...
+//    // ... x = width, y = height, n = # 8-bit components per pixel ...
+//    // ... replace '0' with '1'..'4' to force that many components per pixel
+//    // ... but 'n' will always be the number that it would have been if you said 0
+//    stbi_image_free(data)
+//
+// Standard parameters:
+//    int *x                 -- outputs image width in pixels
+//    int *y                 -- outputs image height in pixels
+//    int *channels_in_file  -- outputs # of image components in image file
+//    int desired_channels   -- if non-zero, # of image components requested in result
+//
+// The return value from an image loader is an 'unsigned char *' which points
+// to the pixel data, or NULL on an allocation failure or if the image is
+// corrupt or invalid. The pixel data consists of *y scanlines of *x pixels,
+// with each pixel consisting of N interleaved 8-bit components; the first
+// pixel pointed to is top-left-most in the image. There is no padding between
+// image scanlines or between pixels, regardless of format. The number of
+// components N is 'desired_channels' if desired_channels is non-zero, or
+// *channels_in_file otherwise. If desired_channels is non-zero,
+// *channels_in_file has the number of components that _would_ have been
+// output otherwise. E.g. if you set desired_channels to 4, you will always
+// get RGBA output, but you can check *channels_in_file to see if it's trivially
+// opaque because e.g. there were only 3 channels in the source image.
+//
+// An output image with N components has the following components interleaved
+// in this order in each pixel:
+//
+//     N=#comp     components
+//       1           grey
+//       2           grey, alpha
+//       3           red, green, blue
+//       4           red, green, blue, alpha
+//
+// If image loading fails for any reason, the return value will be NULL,
+// and *x, *y, *channels_in_file will be unchanged. The function
+// stbi_failure_reason() can be queried for an extremely brief, end-user
+// unfriendly explanation of why the load failed. Define STBI_NO_FAILURE_STRINGS
+// to avoid compiling these strings at all, and STBI_FAILURE_USERMSG to get slightly
+// more user-friendly ones.
+//
+// Paletted PNG, BMP, GIF, and PIC images are automatically depalettized.
+//
+// ===========================================================================
+//
+// UNICODE:
+//
+//   If compiling for Windows and you wish to use Unicode filenames, compile
+//   with
+//       #define STBI_WINDOWS_UTF8
+//   and pass utf8-encoded filenames. Call stbi_convert_wchar_to_utf8 to convert
+//   Windows wchar_t filenames to utf8.
+//
+// ===========================================================================
+//
+// Philosophy
+//
+// stb libraries are designed with the following priorities:
+//
+//    1. easy to use
+//    2. easy to maintain
+//    3. good performance
+//
+// Sometimes I let "good performance" creep up in priority over "easy to maintain",
+// and for best performance I may provide less-easy-to-use APIs that give higher
+// performance, in addition to the easy-to-use ones. Nevertheless, it's important
+// to keep in mind that from the standpoint of you, a client of this library,
+// all you care about is #1 and #3, and stb libraries DO NOT emphasize #3 above all.
+//
+// Some secondary priorities arise directly from the first two, some of which
+// provide more explicit reasons why performance can't be emphasized.
+//
+//    - Portable ("ease of use")
+//    - Small source code footprint ("easy to maintain")
+//    - No dependencies ("ease of use")
+//
+// ===========================================================================
+//
+// I/O callbacks
+//
+// I/O callbacks allow you to read from arbitrary sources, like packaged
+// files or some other source. Data read from callbacks are processed
+// through a small internal buffer (currently 128 bytes) to try to reduce
+// overhead.
+//
+// The three functions you must define are "read" (reads some bytes of data),
+// "skip" (skips some bytes of data), "eof" (reports if the stream is at the end).
+//
+// ===========================================================================
+//
+// SIMD support
+//
+// The JPEG decoder will try to automatically use SIMD kernels on x86 when
+// supported by the compiler. For ARM Neon support, you must explicitly
+// request it.
+//
+// (The old do-it-yourself SIMD API is no longer supported in the current
+// code.)
+//
+// On x86, SSE2 will automatically be used when available based on a run-time
+// test; if not, the generic C versions are used as a fall-back. On ARM targets,
+// the typical path is to have separate builds for NEON and non-NEON devices
+// (at least this is true for iOS and Android). Therefore, the NEON support is
+// toggled by a build flag: define STBI_NEON to get NEON loops.
+//
+// If for some reason you do not want to use any of SIMD code, or if
+// you have issues compiling it, you can disable it entirely by
+// defining STBI_NO_SIMD.
+//
+// ===========================================================================
+//
+// HDR image support   (disable by defining STBI_NO_HDR)
+//
+// stb_image supports loading HDR images in general, and currently the Radiance
+// .HDR file format specifically. You can still load any file through the existing
+// interface; if you attempt to load an HDR file, it will be automatically remapped
+// to LDR, assuming gamma 2.2 and an arbitrary scale factor defaulting to 1;
+// both of these constants can be reconfigured through this interface:
+//
+//     stbi_hdr_to_ldr_gamma(2.2f);
+//     stbi_hdr_to_ldr_scale(1.0f);
+//
+// (note, do not use _inverse_ constants; stbi_image will invert them
+// appropriately).
+//
+// Additionally, there is a new, parallel interface for loading files as
+// (linear) floats to preserve the full dynamic range:
+//
+//    float *data = stbi_loadf(filename, &x, &y, &n, 0);
+//
+// If you load LDR images through this interface, those images will
+// be promoted to floating point values, run through the inverse of
+// constants corresponding to the above:
+//
+//     stbi_ldr_to_hdr_scale(1.0f);
+//     stbi_ldr_to_hdr_gamma(2.2f);
+//
+// Finally, given a filename (or an open file or memory block--see header
+// file for details) containing image data, you can query for the "most
+// appropriate" interface to use (that is, whether the image is HDR or
+// not), using:
+//
+//     stbi_is_hdr(char *filename);
+//
+// ===========================================================================
+//
+// iPhone PNG support:
+//
+// By default we convert iphone-formatted PNGs back to RGB, even though
+// they are internally encoded differently. You can disable this conversion
+// by calling stbi_convert_iphone_png_to_rgb(0), in which case
+// you will always just get the native iphone "format" through (which
+// is BGR stored in RGB).
+//
+// Call stbi_set_unpremultiply_on_load(1) as well to force a divide per
+// pixel to remove any premultiplied alpha *only* if the image file explicitly
+// says there's premultiplied data (currently only happens in iPhone images,
+// and only if iPhone convert-to-rgb processing is on).
+//
+// ===========================================================================
+//
+// ADDITIONAL CONFIGURATION
+//
+//  - You can suppress implementation of any of the decoders to reduce
+//    your code footprint by #defining one or more of the following
+//    symbols before creating the implementation.
+//
+//        STBI_NO_JPEG
+//        STBI_NO_PNG
+//        STBI_NO_BMP
+//        STBI_NO_PSD
+//        STBI_NO_TGA
+//        STBI_NO_GIF
+//        STBI_NO_HDR
+//        STBI_NO_PIC
+//        STBI_NO_PNM   (.ppm and .pgm)
+//
+//  - You can request *only* certain decoders and suppress all other ones
+//    (this will be more forward-compatible, as addition of new decoders
+//    doesn't require you to disable them explicitly):
+//
+//        STBI_ONLY_JPEG
+//        STBI_ONLY_PNG
+//        STBI_ONLY_BMP
+//        STBI_ONLY_PSD
+//        STBI_ONLY_TGA
+//        STBI_ONLY_GIF
+//        STBI_ONLY_HDR
+//        STBI_ONLY_PIC
+//        STBI_ONLY_PNM   (.ppm and .pgm)
+//
+//   - If you use STBI_NO_PNG (or _ONLY_ without PNG), and you still
+//     want the zlib decoder to be available, #define STBI_SUPPORT_ZLIB
+//
+//  - If you define STBI_MAX_DIMENSIONS, stb_image will reject images greater
+//    than that size (in either width or height) without further processing.
+//    This is to let programs in the wild set an upper bound to prevent
+//    denial-of-service attacks on untrusted data, as one could generate a
+//    valid image of gigantic dimensions and force stb_image to allocate a
+//    huge block of memory and spend disproportionate time decoding it. By
+//    default this is set to (1 << 24), which is 16777216, but that's still
+//    very big.
