I've writen (very) simple test program for Linux, you can download it from:
This program, like Wine, is using only one X window, and other GL
scenes are emulated. I can to this same for Wine, and it will be first
real improvement, because many GL scenes now will be working parallel
and will be drawed in good place (not like now, when everything is
drawed in lower-left corner). The second and the last improvment and
the hardest one, is to 'synchronieze' GLXContext with X Window
Context. Maybe I will have to draw Wine subwindows by OpenGL in this
same GLXContext (I'm not sure if it is acceptable), or just draw GL on
this same Pixmap.
