The actual resolution that the monitor hardware is capable of producing is 
1024x800 @ 60Hz or 1024x1024 @ 50Hz.  1008 is a magic number, the maximum size 
of a non-ECS Agnus' largest blit (ECS Agnus can blit 32K pixels or somesuch).
Under UNIX, for example, they drive the display with the CPU, and you get all 
1024 pixels.  I suppose they could do this with an ECS Agnus too.
