FLTK1.1 Quartz support:

- added a 'test/unittests' which wil check for identical drawing on all
  platforms. This was desperatly needed to fix tremendous problems in
  getting the Quartz drawing routines right
- disabled anti-aliasing for functions that draw straight lines at integer
  coordinates
