The configs are useless.  Applications can only ask for "bits >= X".
There are still 24-bit depth / 8-bit stencil configs, and, last time I
checked, 8 >= 0.  There is no way to ask for a 24/0 config that wouldn't
instead give a 24/8 config.

I need two pieces of information:

  - A diff of the output of glxinfo immediately before and immediately
    after this commit.

  - A list of what config attributes compiz is requesting.  It should
    be easy enough to instrument choose_visual in glxcmds.c to dump out
    attribList.

It should be pretty easy to root-cause this problem with that data.
