Yes, when I originally ported to Quartz, I wanted to get Box drawing correctly, but still allow for antialiasing somehow. Since no API for antialiasing exists (yet) in FLTK, I used the 1-pixel trick. I assume that this is the time to introduce an API for antialiasing... . You will also find some source code for "unittest.cxx" in the "test" directory. The idea was to verify pixelwise drawing between platforms, but was never finished. Maybe another item that would be useful to revive.
