In principle, yes, though it's going to be a lot of work.
What is much better supported is Balloon rendering (the engine behind
Squeak's Flash player). Basically, you just send #asBalloonCanvas to
a regular Canvas, set the antialiasing level (up to 4), and draw.
See, for example, WatchMorph. Create one, and enable AA in its halo
menu.

Yes, the Rome-Tweak package contains a RomeTweakCanvas that mimics
CTransformCanvas, which is normally used for Tweak rendering. It's
much easier to do than for Morphic because Tweak has a much cleaner
graphics model. You can toggle its usage on and off, it's got a nice
quality boost. The plan was to use this while transitioning to a pure
RomeCanvas, but this effort has stalled.

Yes, but there are many places in Morphic that rely on the canvas
being a FormCanvas, and even direct bitblt operations.

This isn't exactly newbie stuff, so I'd rather take this to squeak-
dev. There is no Rome list, as far as I know you are the first one
trying to use it for Morphic rendering.
