damn, occasionally sent replies to authors, although I think it should go
to the list. Here it go again:

As a person having rather *plain* English I say:

cnv(m11,m12,m13,m21,m22,m23,m31,m32,m33,d) is equal to:

(m11*src(x-1,y-1,z) +
m12*src(x,y-1,z) +
m13*src(x+1,y-1,z) +
m21*src(x-1,y,z) +
m22*src(x,y,z) +
m23*src(x+1,y,z) +
m31*src(x-1,y+1,z) +
m32*src(x,y+1,z) +
m33*src(x+1,y+1,z))/d

oh maybe I put it upside-down... I'm not sure... but I think you got the
idea.

I guess this will lead to a full-scaled image editing program like
Photoshop in the end <g>

Hm, seems to be good idea! What kind of images allowed? Pure FF generated?
Or something FF just played a most important role to?

Open. Usually graphics designers and filter developers are different
beings, and the list is, originally, for developers. But good graphics
comes from designers...
