 Replying to [comment:1 glynn]:

 > The only reliable way to generate image files using OpenGL is to render
 to an off-screen target such as a pBuffer or GLXPixmap. But those require
 support from the driver, and we haven't had much luck with either approach

 Actually, using a GLXPixmap works fine for me with both Cygwin's XWin.exe
 and X.org with the "nv" driver (that's the FOSS driver with no DRI/DRM
 support; I haven't tried the proprietary "nvidia" driver yet).

 Neither of those X servers support GLX 1.3, so I haven't tested pBuffers
 yet.
