	The 3201 format is also called APP Format and it originated on
the French 3200 slide shows.

	The 3201 is a compressed format.  The format is as follows:
(as I remember it off the top of my head)

	Offsets		Description
	-------		-----------
	$0-3		Pascal String 'APP'
	$4-1903		200 palettes, as in raw data
	$1904-xxxx	Packed graphic data.  (using Pack_Bytes)

	This format is pretty popular.  The only thing I don't like
about it is the fact that it doesn't have its own filetype.  Maybe we
should request one for it.  Without a filetype (they are usually
BINs), it makes having a file filter a pain.

	To answer your question though, DreamGrafix will load and save
3201 graphics.  It will also load and save the rest of the supported
graphic filetypes, including APF 256 and 3200, 3200 raw data, and
DreamGrafix 256 and 3200s.
