  glapp.c - Simple OpenGL shell
  
	There are several options allowed on the command line.  They are:
	-height : what window/screen height do you want to use?
	-width  : what window/screen width do you want to use?
	-bpp    : what color depth do you want to use?
	-window : create a rendering window rather than full-screen
	-fov    : use a field of view other than 90 degrees
