This is pretty cool. :^)
GraphicsBitmaps are now mapped into both the server and the client address
space (usually at different addresses but that doesn't matter.)
Added a GUI syscall for getting a window's backing store, and another one
for invalidating a window so that the server redraws it.
Okay things kinda sorta work. Both Bochs and QEMU now boot into GUI mode.
There's a ton of stuff that doesn't make sense and so many things to rework.
Still it's quite cool to have made it this far. :^)
