Hi,

Not sure if this is very critical, but I have noticed a problem with 
r.shaded.relief. If the region is set to 10m and then a shaded rel. map is 
produced from a 30m input data, a corrupt map is produced. 


example with spearfish data:

# set region, and force 10m resolution
g.region rast=elevation.10m -p

# compute shaded rel. map from 30m res data:
# see image [1]
r.shaded.relief map=elevation.dem shade=shade

# compute shaded rel. map from 10m res data:
# see image [2]
r.shaded.relief map=elevation.10m shade=shade --o

This was done with today's SVN.
