STR #1131: there is no good way in Mac OS X to support an OpenGL
overlay (well, at least none that I could find) so I decided to
simplify the overlay code. FLTK tricked a little using the
front render buffer, however OS X 10.4 does not support
that anymore. Anyway, here's the slow, but working, solution.
