Yeah, what I had in mind was something like a "brightness" filter where 
things like sienna photos could be done by specifying two "end colors" 
for a monochrome gradient. Like in my z_buffer patch, which allowed you 
to specify two colors to blend between.

I really think the isosurface functions would be good for this. I don't 
see a real reason to "reinvent the wheel". The code for these already 
exists...it would just have to be modified to support the extra 
variables.
