Compiz FBConfig selection criteria

At some point I think I fixed exactly the bug you describe in compiz.  The
GLX_BIND_TO_MIPMAP_TEXTURE_EXT configs should be preferred but not required.
If one isn't found, a flag should be set disabling mip-mapping when using
that config.  I would recommend looking through the FBConfig selection code
and ensuring it still works that way.
