Just a quick note: it's already implemented in r.resamp.bspline in
7.0. r.resamp.bspline interpolates a raster to the current resolution,
filling NULL cells on the fly, or optionally only interpolates NULL
cells. Available methods are bilinear and bicubic, tested with SRTM
data, filling large gaps in the European Alps.

Proper report in trac once I'm back in office.
