Has anyone determined (analytically or empirically) the distribution of
values in a bozo pattern?

In other words, suppose I want to make a color_map in which each of N
colors covers 1/N of the total surface area; where do the boundaries go?

Why don't you do a nice big render of a bozo plane, then use the file as an
image_map in MegaPOV and use eval_pigment to make a histogram?

Why not just use eval_pigment() directly with a bozo pigment? Or even 
better, just use eval_pattern() with bozo...

Duh, of course!!!
See, originally I was going to say write a C program to read he pic and
make a histogram. Then I realized that could be done with MegaPOV, but was
too stupid to realize the first render was a wasteful step...
