#614 new defect

r.proj method=cubic_f passes nulls

Description

Hi,

Running r.proj with method=cubic_f should not propagate NULLs, yet I still get some.

In this set of commands the Northern Hemisphere reprojects properly, but the Southern Hemisphere gets a diagonal row of NULLs from the upper right to lower left of the region.

... happens along 180 longitude ...

Since cubic_f is essentially a patch of cubic,bilinear,nearest, only nulls left from nearest should pass thru (propagate).

...testing...

Looks like it happens with cubic, bilinear AND nearest also. So it's not the fallback logic.
