window-x11: Don't ever send ConfigureNotifies for OR windows

Browse source 
There's a race here. If an OR window hides itself, moves, and then shows
itself, we will send a ConfigureNotify for the old size of the window
and might receive it after the client moves itself, causing us to show
the window at the wrong location.

Simply not sending the ConfigureNotify is the easiest thing to do.
