v.surf.idw does not respect mask
|Reported by:||dnix||Owned by:|
Unable to use a mask with v.surf.idw. When mask is set with r.mask, it is ignored by v.surf.idw and the entire region is interpolated regardless of the mask.
The documentation notes for v.surf.idw states that a mask may be used to limit the interpolation area: "If the user has a mask set, then interpolation is only done for those cells that fall within the mask."
Might this be similar to defect fixed for v.surf.rst in #1775?
