Also probably going to change things around a bit to get the current 
FULLSCREEN code to properly use the same mechanism FULLSCREEN_WINDOW uses, 
if I can get it to not act funny. It turns out that since the window is 
already the right size, no resize event will get sent, and all that code 
waiting for that event will wait forever! fun times. My earlier attempt 
today just made the fullscreen window toggle function take a bool argument 
telling it to wait or not. worked ok, though as I mentioned before, some how 
kwin will let the expose like feature pop up even with the window 
fullscreen.
