To tell the truth, I didn't test it.  It probably fails.

There is an option I recently added to render offscreen contexts using 
framebuffer objects, when the GPU supports FBOs.  See 
kQ3DrawContextPropertyAcceleratedOffscreen.  I have not yet used that on 
Windows, so I cannot swear it is bug-free.

OK, I just added code to restore yon at the end of the frame.
