[Olena-patches] olena 10.117: piece morpher

Index: olena/ChangeLog from Simon Odou &lt;simon(a)lrde.epita.fr&gt; * oln/morpher/piece_morpher.hh: To use a piece of image like a real one. * oln/core/abstract/image_with_impl.hh: * oln/core/point2d.hh: Able to construct a point2d from a point1d. * oln/core/point2d.hxx: Likewise. * oln/core/point3d.hh: Able to construct a point3d from a point2d. * oln/core/point3d.hxx: Likewise. * oln/core/abstract/image_with_dim.hh: Fix a bug. * oln/core/abstract/image_with_impl.hh: Fix (same).
