[Olena-patches] ***SPAM*** L3 1990: Revamp and specialize mln::accu::volume_.

https://svn.lrde.epita.fr/svn/oln/trunk/milena Index: ChangeLog from Roland Levillain &lt;roland(a)lrde.epita.fr&gt; Revamp and specialize mln::accu::volume_. * mln/accu/volume.hh (mln::accu::volume_<I>): Take an image instead of a data type as parameter, and always work with a mln::util::pix<I> instead of a free type. (mln::accu::volume_<I>::argument): Change typedef from `T' to `mln::util::pix<I>'.
