on images such as blurring \, sharpening \, finding edges \, embossing
\, cellular automata and many others.;
#X text 232 316 This is the convolution grid and it gets stored in
the other object. If rows2 and/or columns 2 are odd numbers \, then
the centre of convolution is the middle of the convolution grid. If
they are even numbers \, then the chosen centre will be slightly more
to the left and/or to the top \, because the actual middle is between
celle of the grid.;

for each of those parts at (y \, x). A rectangle of such parts \, centered
around (y \, x) is combined with the convolution grid like a [#] of
operation op_para. Then each such result is folded like [#fold] of
operation op_fold and specified base. The results are assembled into
a grid that is sent to the outlet. Near the borders of the grid \,
coordinates wrap around. this means the whole grid has to be received
before production of the next grid starts.;
