If I may not agree - *inter* suggests this module will be able to fill
null gaps. This is not the case. It will even make the opposite - make
the gaps bigger in the output for method= bilinear and bicubic, if nulls
are present in the input.

This module is for re-sampling and r.resample is the only good name I
can think of currently.

IMHO: drop r.bilinear, replace r.resample. To provide compatibility with
old r.resample (that performed nearest neighbor only) set the default
method=nearest. This will keep things simple and backward compatible.

If it is necessary to mantain r.bilinear compatibilty, make it a script
that calls r.resample method=bilinear.

What do you think?
