as far as I know, llvmpipe doesn't support texture-from-pixmap, thus
making a compositor based on it fairly difficult. not impossible, just
unbearably slow.

the same applies to Mesa swrast, which doesn't expose the required GLX
support.

remember: a compositor is *not* a game, even if they both use OpenGL.
