Almost all raster commands do this automatically. GRASS raster
commands normally operate upon the current region, which can be set
and queried using g.region.

Any maps which are created have their bounds and resolution determined
by the current region; any maps which are read are automatically
cropped, padded (with nulls) and/or resampled according to the current
region settings.
