There doesn't seem to be any bug reports about XPM colours not working
correctly -- what are the symptoms?

XPMs are attractive in that they allow addressing colours by name, and
you can therefore alter them on-the-fly without editing the images.
(See `gnus-logo-color-alist' for something that exploits this.)  You can
do the same with SVG images, but then you need SVG support.  And you
can't do this with PPMs, I think.

So I'm not sure I agree with that TODO item, unless I'm missing
something (which I may well be).
