	I am told that the fastest way to copy the figures to the
	screen is rather
	obtuse.  It involves setting the stack pointer to the beginning of
	graphics memory and PEAing each word of data onto the stack, which
	is now the screen.  I suppose that you would either have to save
	a picture in a modified format or load it in in a special way, because
	the picture would actually look like this : PEA <value> PEA <value>
	etc.  So to display the picture, you could JSR to it.  Sounds
	slick but I have never tried it.
