Ahh!!
I updated it again! (As kind-of promised in the RedAverage thread, heh.)
Now it ought to be more-or-less usable, and there ought to be none of the blending caused by my stupidity.
I'll go ahead and say that you
could change the weights from (*,x,*,-(x+1)) to (*,x,*,-x) to gain a nice absolute noise filter, but for some reason I decided to mask some more. :P
Oh silly me, hmm?
