These seem to be remote desktop clients that transfer the screen image
from another system. If <canvas> had the API Rich is proposing, would
you expect these apps to use the remote system accessibility API to
transfer the accessibility API state over? How does Microsoft Remote
Desktop and VNC deal with this with non-Web clients?

This is a game engine demo and doesn't represent GUI apps.

This looks like a demo and not like a serious app that one would spend
time making accessible. It has rather terrible usability even for non-AT
mode of operation.

This looks like something that really ought to be SVG.

These are mainly graphics demos like fractal drawing programs.
