It would be useful if it also supported basic transforms like scaling 
(so we can read terminals comfortably at high screen resolutions, 
although we may not want to scale the pictures); Quartz and OpenGL will

I would definetely recommend starting out with Quartz/CoreGraphics 
instead of a QuickDraw API.
