[GRASSLIST:982] new scripts for testing...

[David Finlayson]

I posted a couple of new scripts to the GRASS Wiki AddOns sections
that might be useful for others:

r.eucdist: calculates the (approximate) Euclidean distance from known
values in a raster.

r.smoothpatch (depends on r.eucdist): Makes a composite raster from
two input layers using a distance-weighted smoothing across the
transition between the two data sets. I use this for merging two DEMs
from different origins/resolutions so that the final merged DEM has a
smooth transition across the edge.

Please send me any comments or suggestions for improvement. I use
these a lot in my work and would love to make them faster and more
flexible.
