[GRASS-user] srtm - r.fillnuls

when playing with SRTM data I found out that `r.fill.nulls`'s RST
method usually fails [1] -- compared to `method=cubic` (cubic spline
interpolation) [2]. Is it expectable?

Wouldn't be better to change default method to 'cubic' (v.surf.spline
is quite slow anyway)?

Thanks, Martin
