Description

While somewhat infrequently used in general, apng support would allow users to add motion screenshots for their games, animated backgrounds, and -potentially- animated achievement icons down the line (I won't be pursuing implementation of that unless support can be added). I inquired on Discord and apparently it -appears- it should be simple to implement. Of course, as with anything involving the menu code, I realize that may be far from the truth.

Research direction

No source file or test is named. Start by locating RetroArch's menu code and the current image-loading path, then trace how screenshots and backgrounds are decoded and displayed. Done means APNG assets render correctly in the requested menu use cases without regressing existing image support.
