Just bear in mind that the colour table extension is performed at
the wrong side of the texture filter for cmap style interpolation
and so will interpolate through other cmap entries unless you are
somehow able to exploit spatial colour distribution when generating
the 8 bit information. The fact that this is a cmap animation rather
than a simple cmap 8bit image probably saves you from these concerns
because of the adjacency of incremental values typical of such
animations.

Cheers,
Angus
