Comment (by Nikos Alexandris):
The statistics in https://trac.osgeo.org/grass/ticket/774#comment:13, show
that going from either an 8-bit or 16-bit RGB to HIS and back to RGB,
figures are not scrambled. Some rounding applies, as exemplified in in the
same stats above. Even visually, I confirmed (not documented here) that
the old and the new versions perform the same.
It will break i.pansharpen, unless i.pansharpen treats intensity ranging
in [0,1].
Nevertheless, another set of tests would be certainly good to have to
confirm the correctness of the new version.
