[Olena-patches] 691: Fix the mutability of value-wise random accessible images.

https://svn.lrde.epita.fr/svn/oln/trunk/olena Index: ChangeLog from Roland Levillain &lt;roland(a)lrde.epita.fr&gt; Fix the mutability of value-wise random accessible images. * oln/core/typedefs.hh (is_value_wise_mutable_type): New virtual type declaration. * oln/core/abstract/image/value_wise_accessibility/hierarchy.hh (struct case_<image_hierarchy_wrt_value_wise_accessibility, E, 2>): Re-enable. Swap with... (struct case_<image_hierarchy_wrt_value_wise_accessibility, E, 1>): ...this case. * oln/morpher/with_lut.hh (vtypes< morpher::with_lut<Image, Lut> >::is_value_wise_mutable_type): New virtual type.
