For resapling to a coarser resolution, where one output cell covers
multiple input cells, use r.resamp.stats.
For resampling to a finer resolution, use r.resamp.interp,
r.resamp.rst or (in 7.0) r.resamp.filter.

Set the region to the desired output resolution. The input will be
read at its native resolution.
