        * gtk/src/gtk_signals.defs: regenerated, keeping hand-coded changes,
        after adding some extra GTypes to tools/extra_defs_gen.
        * gkt/gtkmm: Added cellrenderer_generation.[h|cc], with some of the
        templates and template specialisations previously in
        treeviewcolumn.[hg|ccg]. This allowed them to be reused in
        gtk/src/celllayout.hg for a pack_start(model column) template.
        * demos/gtk-demo/: Added example_ui_manager.cc - a C++ version of
        the C one.
