ffffuuuullllllllssssccccrrrr allows a program write to the entire screen. It does this by
eliminating the protections that normally prevent a graphics process from
drawing outside of its current window. ffffuuuullllllllssssccccrrrr calls
vvvviiiieeeewwwwppppoooo((((0000,,,, ggggeeeettttggggddddeeee((((GGGGDDDDXXXXPPPPMMMMAAAA))))----1111,,,, 0000,,,, ggggeeeettttggggddddeeee((((GGGGDDDDYYYYPPPPMMMMAAAA))))----1111)))) and oooorrrrtttthhhhoooo2222 to set up an
orthographic projection that maps world coordinates to screen
coordinates. The current viewport and matrix state are not saved; it is
the caller's responsibility to do this.
ffffuuuullllllllsssscccc only affects graphics output; input focus management is unchanged.
