diamondburned 6140b5a131 Clarified text.{Imager,Avatarer}'s bound behavior
This commit clarifies text.Imager and text.Avatarer's bound behaviors.
Prior to this, the only behavior that those two interfaces have
regarding bounds is that only the starting bound matters, because images
must not substitute texts.

This commit clarifies that images are allowed complement other sections.
For example, a Mentioner can "have" an Imager by having the bounds
overlap.

These details are intentionally vaguely defined (it doesn't list any
interfaces beyond Mentioner), so implementations of either side can
implement these however they want, as long as the bounds overlap.

In the future, further clarification rules may be added if needed.
