Subject: Quartz implementation for FLTK 1.1: - added very crude font support -
 added line drawing support - added line color support - added filled shapes
 support - added some arc and circle support (no ovals) - attempt at getting
 the clipping working, however the stack oriented   design of Quartz is
 starting to become a real hassle
