Comment:

 example on how to shrink maps added to the r.grow man page in r41617. I
 guess you could wrap that in a script called r.shrink if you really wanted
 to.


 btw, radius=1 is growing 1 cell outward. radius=0.5 is growing 1/2 a cell
 outward (which is still outward). radius=0 is the status quo, and
 radius=-xx would be inward in your proposal. it's a distance not a
 multiplier.
