GTK actually has special code in it which creates a whole new window on
the other screen and destroys the old one, recreating the appropriate
resources. Unless we want to rewrite every X app to be able to do this
(or play some nasty tricks in an Xlib shim), fixing it in the server
seems like the best way to go.
