Application specific desktop geometry
How can I given different applications different desktop geometries. I have a kiosk application that uses the right 1/4 of the screen for status information. I don't want the user to be able to move applications like vlc and flash windows into the right 1/4 of the screen even if they run in full screen mode. How can I restrict certain applications to only render in the left 3/4 of the screen. I don't want to have to start another X server for them because I will lose hardware acceleration.
