It's not exactly a blight on my life, but I wanted to save GIFs in
web-specific colour tables (those with colours that are 'safe' for a
wide variety of displays). If COLOR_QUAN had returned the 'correct'
table, shuffling the colour indicies to get back the ordering of the
web-specific table would have been a one-liner. As it is, you have to
step through the table looking for closest matches, and if you're
going to do that you might as well do it from the start.

My optimal solution? Use Photoshop. :-)
