Heh, disregard that; apparently I can't brain today: The patches do
work. airlied clarified on IRC that GLX_EXT_texture_from_pixmap was
only working in indirect rendering (so `LIBGL_ALWAY_INDIRECT=1
glxinfo` actually will show TFP, although `glxinfo -i` doesn't for
some reason). These patches just make the direct rendering case start
working (glxinfo prints the tfp extension three times with or without

Trying to start compiz on Ubuntu Lucid with llvmpipe and these patches
applied to git gives a whole different kind of error: before, it would
show everything as corrupted; with these applied, it shows windows and
buttons as all-white or all-black. (pressing Esc immediately will turn
compiz back off - since that will close out the dialog that always
pops up to ask if you want to keep these settings with a 'no').
