High-Res Graphics
-----------------
All high-res graphics commands use the 320x200, 16 color Apple IIGS
graphics screen.  The will function on the 640x200 screen as well, but
toolbox calls must be used to set up that screen.

QuickDraw II graphics commands may be used without initializing the tools,
setting up desktop programs, and so forth so long as HGR is used at least
once before the first QuickDraw II call.
