/*
Matt: I wrote individual methods for every class. They are virtual, so the
correct function is called, depending on the active driver.
By having individual methods, multiple drivers can co-exist, for example
Quartz, OpenGL, and a printer driver.
The individual implementations should eventually go into files that are
included into this file, based on the configuration, for example:
src/cfg_gfx/quartz_rect.cxx
src/cfg_gfx/gdi_rect.cxx
src/cfg_gfx/xlib_rect.cxx
Porting the graphics system to a new platform then requires to copy one of
these files and implement the virtual functions. point() is the only function
that *must* be implemented when deriving from 'Fl_Minimal_Graphics_Driver"
(which is still to be written)
