 idea and method from gdaldem -compute_edges.

 I just discovered the issue of null borders in the output of
 G7:r.slope.aspect and I tested this flag in grass dev, but nothing
 changes. Is there anything else that needs to be set?

 This is what I do:

 {{{
 g.region vector=firestations align=elev_state_500m
 r.slope.aspect -e elevation=elev_state_500m slope=slope_500
 aspect=aspect_500
 }}}

 The output still has one pixel less all over the 4 borders. See the
 attachment.
