I sampled an image_map pigment of a photo of my son with eval_pigment, and
plotted the resulting vectors in RGB-space (step 10 in x and y).
The scanning takes 33 sec (2448 x 3264).

I want to find a way to "cluster" similar values - I'm experimenting with
rounding the RGB channels, etc.

I also made a sort of "parametric" RGB map - translate along x by gray, rotate y
by green, then x by red, then z by blue
