     Description  : Routines to ease GLUT->FOX migration
                    This implements a good chunk of the GLUT API in terms of
                    FOX.  Currently this lacks the more exotic GLUT features
                    like overlays, subwindows, menus, geometric primitives,
                    and fonts.  For the latter you continue to use GLUT. Those
                    features are independent of GLUT's job as windowing system.

                    Because it is possible to include both glut.h and fxglut.h,
                    all the functions here are prefixed with fx to avoid 
                    naming clashes.

                    If you've got a pretty ordinary simple glut app with a few
                    callbacks set up, it should be pretty easy to convert over
                    to fxglut.  Just replace the word "glut" everywhere with
                    "fxglut" (and "GLUT" with "FXGLUT").  Add fox and fxglut
                    to libs to link with, and it should just work.

                    When you're ready to add FOX-specific stuff to your app,
                    you can get pointers to the FOX stuff used by the FXGLUT
                    implementation under the covers with these functions:
                        FXApp* fxglutGetApp();
                        FXWindow* fxglutGetFXWindow(int id);
