I am a little stuck (again) on how to make appropriate use of pfColortable.
I have created a simple database using MultiGen, which consists of just 9
cubes, in a 3 by 3 grid. Each cube is of a different unique primary color
(full red, full green, full blue, cyan, magenta, etc.).

I have minimally hacked main.c of perfly following Example #2 in the
pfColortable man page, as follows:
- Just before the application main loop, I call my routine 'SetupLUT()'
- in that routine, I do the following:
        pfEnable(PFEN_COLORTABLE);
        ctab = (pfColortable *)pfNewCtab(ctabsize, pfGetSharedArena());
        (then a bunch of calls to pfCtabColor for all indices of the table)
        pfApplyCtab(ctab);
        pfOverride(PFSTATE_COLORTABLE | PFSTATE_ENCOLORTABLE, PF_ON);

What appears to me to be happening is that all the pretty colors :-) of
my colored cubes map to index 0 of the color table, so that it does not
actually matter what I set any other index to (or for that matter how long
my colormap is - ie the value of ctabsize above).

Where am I going wrong? I would really appreciate some help, since I have
been beating my head against the wall for a while, and I can't find any
hints in the docs.

Thanks very much!
Carlo.
