Thanks again.  This is all very new to me, and I guess I don't fully
understand where these buffer types would come into play.  Bearing in
mind that I really don't care whether non-OpenGL applications are
hardware-accelerated, does that simplify anything?  It would be
sufficient if only OpenGL applications could render using the GPU.  The
compositor itself doesn't necessarily need to.

I guess I was hoping to take advantage of the EGL_PLATFORM_DEVICE_EXT
extension that allows for off-screen OpenGL rendering.  It currently
works with nVidia's drivers:
