       [ threshold BOOL ]
       [ PIGMENT_MODIFIERS... ]
     }

Looking just at simple blob so far I see a few things.

1) Wondering it the option [threshold BOOL] should be inside the 
potential block syntactically?

1a) I could not seem to get the threshold option to function.

2) See attached image. I think the potential value is turning on filter 
and/or transmit as the value approaches 1.0. We should not be able to 
see the green y axis below the plane.

3) See attached image. Something odd is going on with the shadows cast 
over the >0 blob potential areas - and where the strength is set to 1 
especially.
