Comment:

 Replying to [comment:17 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 the
 same stats above.  Even visually, I confirmed (not documented here) that
 the old and the new versions perform the same.

 This sounds very promising.

 > It will break i.pansharpen, unless i.pansharpen treats intensity ranging
 in [0,1].

 Would it be hard to add that to i.pansharpen?

 > Nevertheless, another set of tests would be certainly good to have to
 confirm the correctness of the new version.

 I'd suggest to "svn move" it from sandbox to addons for wider testing with
 g.extention.
