        * configure.in: require GTK+ 2.2. The 2.0.x series is no longer
        maintained, and there are some very real bugs that won't go away.

        * app/gui/about-dialog.c
        * app/widgets/gimppreviewrenderer.c
        * app/widgets/gimptoolbox-color-area.c
        * plug-ins/common/uniteditor.c: remove special casing for GTK+ 2.0
        vs. 2.2

        * app/widgets/gtkwrapbox.[ch]
        * app/widgets/gtkhwrapbox.[ch]
        * app/widgets/gtkvwrapbox.[ch]: remove deprecated functions

        * app/gui/gui.c: free return value of gdk_get_display ()

        * app/widgets/gimpcontainertreeview.c: use gtk_list_store_move_before ()        for reordering.
