Its easy for mosaic filtering and subsequent resizing.
I will write such a macro to avoid future discussions.
But in my eyes correction of gamma, brightness or contrast are much more
bending the rules than the antialiasing methods in discussion.

By the way using Pov-Ray for filter effects one can do some nice effects.
Does anybody know the exact algorithm for Gaussian Blur?
How the image edges are processed?
