[Olena-patches] oln 10.194: Add func_morpher, rotation, translation, fpoint2d, and fdpoint2d

Je sais que y'a plein de trucs crades dans ce checkin, alors si vous avez des suggestions, n'hesitez pas a m'en faire part, j'en tiendrai compte lorsque je retoucherai tout ca (apres mon seminaire). Index: olena/ChangeLog from Damien Thivolle &lt;damien(a)lrde.epita.fr&gt; * oln/makefile.src: Add new files to the distribution. * oln/transforms/shapelets.hh: Small Changes. * oln/morpher/func_morpher.hh: Add file, image can now be seen through a functor. * oln/core/fpoint2d.hh: Add file. Contain floating point implementation. * oln/core/fdpoint2d.hh: Add file. Contain floating dpoint implementation. * oln/geom/translate.hh: Add file. Implementation of image translation using floating dpoint. * oln/geom/rotate.hh: Add file. Implementation of image rotation using floating point. -2004-07-06 Damien Thivolle &lt;damien(a)lrde.epita.fr&gt; +2004-06-07 Damien Thivolle &lt;damien(a)lrde.epita.fr&gt; * oln/transforms/shapelets.hh: Change functions to functors, bug fixes.
