For proper 16bit support, levels/colors/etc dialogs need to talk in
terms of 0..65535 range rather than 0..255 when they are working on
16bit data, and so should then be able to talk in terms of
0..4294967295 for 32bit int.
If I understand this patch correctly, once a system for working with
'native' ranges is implemented and the basic system implemented by the
patch is proven, support for 32bit int/channel  should be relatively
simple.  Whether floating point support would require more work, I do
not know.

There are also various rough spots to consider; we should be able to
enter hex colors with 16bit or even 32bit per channel precision, if we
can edit 16bit images.

Sadly I haven't been able to try this patch yet -- my GIMP doesn't
want to compile, due to babl/gegl synchronization issues.
