It's slightly different. Whenever a client wants to change an atom (such
as opacity), it sends a client message with the request to the WM which
then decides to modify the actual X property or to ignore it.
Whenever there is a client message requesting an
opacity/saturation/brightness change, compiz changes the paint modifier
(w->paint) and sets the atom. Hence, obs does the same :-)
