I mean the GL extension to X that adds GL support to X. (GLX, I think
it is.) Or maybe you are using software GL, in which case I'm not sure
how it works. Or maybe the X extension is DRI. Anyway, X servers have
some sort of special support for 3D acceleration.

"man XGetImage()" goes into some detail here, though I'm not sure the
man page is totally accurate.
