I can't help you there - there are two things I have done my best
to know as little about as I could: C++ and X Windows :-)

Wouldn't the way the Squeak group did graphics avoid this kind
of thing and make porting easier? They do everything in Squeak
(mostly translated to C, though) and only need the host GUI to
provide a way to copy from internal buffers to the screen. Then
practically everything becomes much easier to debug and actually
possible to fix.
