You'll have to do something like impose a mask for the OpenGL rastering
by extracting the internal region handling of the windowing system and
a convert that into OpenGL a compatible z-buffer, I guess.
It's pretty non-trivial stuff and most like will have to intimately
require some trickey examination of how QuickDraw does clipping and region
handling.
I was experimenting with the old QuickDraw several years ago with this
stuff, but didn't progress much into these areas. Probably for the better. ;-)
