Share GraphicsBitmaps between the windowing server and the client process.

This is pretty cool. :^)

GraphicsBitmaps are now mapped into both the server and the client address

Added a GUI syscall for getting a window's backing store, and another one
for invalidating a window so that the server redraws it.
