All of the solutions proposed to save a graphics screen to disk assume
you can have one data structure that includes the entire screen.  This
just isn't true for VGA modes.  The memory required is greater than the 64k 
byte limit on arrays.

You need to divide the screen up into 4 areas and then use 'getimage'
and 'putimage' for each area.
