So how do window-less objects make something faster?  Less windows for the
server to deal with, smaller working set, easyer to decide where events go.
Bigger working set on the client side, larger working set, harder to decide
what events go with what objects.

What if you have objects that change look when the mouse rolls into them, or
just change the mouse cursor?  If objects had windows assoc'ed with them they
could use Enter/Leave events (or just set the window cursor, and let the
server do it all, no context switches there :-)).  With no windows the only
thing I can think of doing is asking X to tell you each time the mouse moves
(or sit in a polling loop, which is worse).
