[GRASS-dev] r.surf.contour MASKs

[Hamish]

Hi,

re. r43805:

+<p>
+An existing MASK raster map is respected for both reading <em>input</em>
+and writing <em>output</em>.

is that a newly added feature or documenting an old one?

if new, does it help speed up the very slow searches where there
is no input data? (e.g. when the region contains a large lake or
partial ocean, where there are no contour lines)



cheers,
Hamish
