No, OpenGL is not accelerated in Cygwin/XFree86.  We use Mesa for OpenGL
support in Cygwin/XFree86, and Mesa uses FB to draw to an offscreen
framebuffer that is occasionally transferred to the screen.

It sounds plausible that one could tie the Cygwin/XFree86 OpenGL layer into
the Windows OpenGL API, but no one has volunteered to look into the difficulty
of doing so.  I would very much appreciate someone putting a little bit of
time into simply telling us how much time and difficulty would potentially be
involved in this task.
