As far as cairo using glitz, that's not something that cairo chooses
to do on its own. Cairo-using applications choose which cairo backend
to use. And for GTK+ at least, it uses cairo's xlib backend, not

I happen to think that's a good decision for GTK+. If it makes sense
to use glitz, lets keep that as a detail of the X server's
implementation of Render. That way, applications can just use cairo's
xlib backend to talk Render protocol and the X server can use EXA or
whatever glitz-using stuff it might have to accelerate it all as much
as possible.
