  I tested gnome-shell with it; when using alignment table patches (Xorg's
ColorTiling was always false), there was no change. However, when I reverted to
original r300_texture_desc.c, things seem to work more-or-less correctly --
8bpp textures seem to render fine (there's one case when I'm not sure),
however, small 32bpp textures still render incorrectly.
