	640 mode has 4 pure colors per line, 64 per screen with
multiple palette and 800 using the equivalent of 3200 color mode in
640 mode.  That's pure colors though.

	To get 16 colors per line the colors are dithered, not pure.
It is possible to draw in that mode.  Check out the awesome work by Bo
Monroe and Donald McIntosh... (some is in HyperStudio and other stuff
is in Studio City)
