ChangeLog:
2008-01-04 Matthieu Garrigues <garrigues(a)lrde.epita.fr>
Fix convertions between the 4 graylevels types.
* mln/value/graylevel.hh,
* mln/value/graylevel_f.hh,
* mln/value/internal/gray_.hh,
* mln/value/internal/gray_f.hh: All these convertion now work:
gray_f -> gray_<n>, gray_f -> graylevel<n>, gray_f -> graylevel_f,
gray_<n> -> gray_f, gray_<n> -> graylevel<n>, gray_<n>
->
graylevel_f, graylevel_f -> gray_f, graylevel_f -> graylevel<n>,
graylevel_<n> -> gray_<n>, graylevel_<n> ->
graylevel_f<n>.
* tests/value/graylevel.cc: Add more tests for convertions.
