Is there a way to directly draw to the system window using OpenGL so 
that intermediate software blitting is eliminated?

The integration of 3D and 2D on the squeak desktop (World morph) would 
be much easier and faster if there weren't so many layers of copying 
being done, as is the case with my demo video.

If there IS a way, can you create a demo of it,, or explain to me how to 
create a demo of it?
