The real realtime preemption end game

It displays the BSOD at start up, and then prints the normal screen as an overlay on top of it. This way, when something goes wrong, the overlay disappears and you see the BSOD. That is why the option "customize the BSOD" requires you to reboot. That is also why, if you set the background to an image with transparency, you get the BSOD.

(just jocking of course)
