recently I have added a standardized option for sampling interpolation
methods [1], based on lib/raster/sample.c and codes defined in
raster.h [2].

Some modules use 'bicubic' other 'cubic' value. What do you think that
is more preferable? It's bicubic interpolation [3] accomplished using
cubic convolution, right?
