[Olena-patches] 2137: Wrap morphological gradient and area closing.

https://svn.lrde.epita.fr/svn/oln/trunk/swilena Index: ChangeLog from Roland Levillain &lt;roland(a)lrde.epita.fr&gt; Wrap morphological gradient and area closing. * morpho.ixx: Wrap mln::morpho::gradient and mln::morpho::closing_area. * image2d_int_u8.i (meyer_wst): Rename as... (meyer_wst32): ...this.
