The answer to this question seems to be: Because this patch (Replace broken
GLX visual setup with a fixed "all" mode) adds the "best_score" varible, but
does not initialize it to zero. Having fixed this, I'm down to 33 X-visuals,
and 33 GLX visuals. "glxinfo" on my FC6 machine still complains about "Error:
couldn't find RGB GLX visual", but this might of course be a problem with
glxinfo rather than the X server.
This problem turned out to be limited to depth=16. It goes away with this
patch:

I have no idea why. The output from xdpyinfo doesn't change. Output from
glxinfo changes only with (this is the visual created by the Composite
extension):
Visual ID: 37 depth=32 class=TrueColor

plus that I get a bunch of information instead of the error message.
