I thought it was pretty basic...just remap the values, and clamp to the 
[0, 1] range to produce the plateaus. Isosurface functions were the 
natural choice for this, since they can be used as a pattern and have 
access to the noise function.

Yes and no...you could rebuild the patterns in function form, but it 
wouldn't be easy for some. It would be easier to use the pigment_pattern 
for these. However, I think bozo/bumps/spotted were the main 
problem...the other patterns might work fine.
