I don't know in advance how many I will need, and if it is not a multiple of 256
there would be too little weighting on the final set.

Anyway the averaging part works fine - the problem is with the function/pigment
colour mapping beforehand. See below.

I figured out WHY it is doing that - this is the code to map the function to a
colour. It is called 3 times - once for red, green and blue, for each image in
the set before it is averaged.

  pigment {
    function { Fn(x, y, z) }
    color_map {
      [ 0 color Color1 ]
      [ 1 color Color2 ]
    }
  }

....so if the value of the function is more than 1 it will wrap back to the first
colour in the color_map. I have confirmed this is what is happening with
Photoshop's colour eyedropper tool.

Now - HOW do I fix it? I don't want to add a million [ x color Color2*x ]
rows...
