Exactly. If you were using the blurred pigment in an actual scene, you 
could save rendering time this way. But if you are just putting the 
pigment on a plane to render a blurred image, it isn't as useful.

I'm not sure what you mean...are you talking about automatically 
generating the function-of-image-map-of-pigment-function construct? That 
could be done with a simple macro.
