[Olena-patches] 894: Factor code for iterators on dpoints and update.

https://svn.lrde.epita.fr/svn/oln/trunk/olena Index: ChangeLog from Thierry Geraud <thierry.geraud@lrde.epita.fr> Factor code for iterators on dpoints and update. * oln/core/internal/dpoints_piter_impl.hh: New; copy of... * oln/core/internal/dpoints_piter.hh: ...this. * oln/debug/print_nbh.hh: Update. * oln/core/gen/dpoints_piter.hh (dpoints_fwd_piter_): Overload. Update inheritance. (dpoints_bkd_piter_): Update. (include): Update. * oln/core/internal/image_selectors.hh (Image_mutability): Add FIXME. * oln/core/internal/op_image_plus_nbh.hh: Better commentary. Minor fixes. * oln/accumulator/and.hh (include): Remove max_value.hh. (init): Use 'true'. (operator()): Use 'and'. * oln/accumulator/or.hh (include): Remove max_value.hh. (ultimate): Remove. (init): Use 'false'. (operator()): Use 'or'. * oln/core/concept/accumulator.hh: Add FIXME. * oln/core/internal/max_value.hh (oln_min): Remove. * oln/core/internal/min_value.hh: Add FIXME. * oln/morpho/dilation.hh: Fix. * oln/level/local.hh (local_): Update 'or on nbh' version.
