For turning on compositing, perhaps that should be in the
effects" dialog that Fedora has now?
Why would we ever want the user to be in
an environment where
compositing isn't available? I mean, why do we want an off button?
If COMPOSITE is found, I think metacity should leverage it (at least
do automatic compositing at a minimum).
Even for remote X it probably makes sense to have
compositing on I think (less redraws).
