Does What I Want as well.  I'll add some "wellknown colour names", a
few standard palettes that I have somewhere, and eliminate the need
for attach.  Stay tuned for a 0.2b4 (early January, probably).

My current priorities wrt. palette-aware formats:

	1. fix PNG write support
	2. redesign the TIFF writer; its not very good as it stands
	3. make sure that BMP and TIFF work properly with palettes
        |
       99. add GIF write support (not very likely, since Unisys
	   doesn't know the meaning of freeware; it would require
	   me register PIL users, pay 10 cents per user, restrict
	   the use of other parts of PIL, and add a splash screen
	   that is displayed whenever you try to write a GIF file.
	   Same rules apply to everyone using PIL to write an
	   application...  I'm tempted to add a "not to be used
	   for any purpose by Unisys" to the PIL license...)
