Thanks Christoph. For the sake of brevity I'll refer you to my answer to Warp's
post.

I will add though, I checked your link and was impressed to see a blur patch. I
was wondering just the other day how I might blur a texture in POV. I have to
ask though, "Why do you have it implemented where the pigment must be specified
twice rather than just as a pigment modifier?" Also, have you considered
allowing some optional jitter as with area lights to help break up some of the
aliasing artifacts at lower samples?
