/* XXX NSScreen BUG WORKAROUND
The purpose of the following code is to workaround a bug in the NSScreen class.
The problem is that this class doesn't realize that we switched from the original
screen mode to another mode via the CGDisplaySwitchToMode() function and thus
keeps on reporting now out-dated screen attributes like screen width & height.
This however has the unfortunate consequence that our NSWindow would be positioned
incorrectly if the new mode has a smaller Y resolution than the old one. I.e.
if the old Y res was 870 and the new is 480 the window would be placed by 390 pixels
too far below.
