Luboš Luňák 14ae8d2dc9 Support for unredirecting fullscreen windows, i.e. games etc. can paint directly 
and not be slowed down by going through compositing. Turned on and no UI option
in the naive hope that it won't cause any real problems. Maybe effects doing
window previews should get API to suspend unredirect though.
