#X text 216 187 splits the incoming grid into dim(rest...) parts \,
for each of those parts at (xy \, 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. this is the convolution
grid and it gets stored in the object. rows2 and columns2 must be odd
numbers.;
#X text 145 130 here ^ is the parallel operator \, fold is indicated
by + and 0 is its base.;
