If r.neighbours accepted a reference mask to compute convolution only on
non masked points, it could reduce significantly computing time on large
datasets and/or large window sizes. Of course that could be done after the
whole map computation, but computing time would change significantly.
Note that this is different from having an ordinary MASK applied to the
input map, because the input raster is not masked out at all at
convolution time.
