r.grow uses 1 of 3 methods to calculate distances: euclidean, maximum and manhatan. In my case, 
distances are calculated based on an anisotropic surface, where cost of crossing each cell is based on 
factors such as slope, type of road, etc.

r.cost is good for me, but it only calculates distances; not what I call "allocation surfaces" (code of the 
nearest target.
