I agree with you on that. It is better to view color map in their linear form.
And Color Mapper does this as so does the Map Veiwer. What I like to know is...
would the slight difference in placement values have a big difference when
rendering.
 What lead me back to the color map was playing with all the patterns that come
with POV and a few hand made pattern functions. I was thinking of making a
windows program that would let you choose a pattern and let you set all the
things that modifies the pattern. There are a LOT of things that can modify a
pattern:) And at the base is the color map.
 Forgive me if I ramble a bit. I think of the color map more of a placement map.
That is pigment_map, texture_map, normal_map all can have the same placement
values with different things at 'em. So if you make a color_map you can
visualize any of the other maps.
