+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.;
