            * gdk/gdkwindow.[ch]: Add a function gdk_window_invalidate_maybe_recurse()
            for use in "shallow invalidation" of a widget. (Windows belonging
            to the widget, but not to the widget's children)
    
            * gtk/gtkprivate.h gtk/gtkwidget.c gtk/gtksizegroup.c: Add private
            flags GTK_ALLOC_NEEDED, GTK_REQUEST_NEEDED.  These flags are set
            up on ancestors up to the resize container on queue_resize. Size
            requests only actually take place if GTK_REQUEST_NEEDED, size
            allocations only take place if GTK_ALLOC_NEEDED or the size
            changed.
    
            * gtk/gtkcontainer.c gtk/gtkwidget.c: Remove
            container->resize_widgets and the RESIZE_NEEDED flag since the
            above flags are sufficient to figure out what needs to be
            resized/reallocated. Remove code manipulating
            container->resize_widget.
    
            * gtk/gtkwidget.[ch]: Add gtk_widget_set_redraw_on_alloc(); this
            allows widgets to turn off being automatically invalidated is when
            they are resized.
    
            * gtk/gtkwidget.[ch] (gtk_widget_size_allocate): Invalidation when
            a widget is resized or moved is "shallow" as described above -
            only the windows that need to be invalidated are invalidated.
    
            * gtk/gtkbox.c gtk/gtktable.c gtk/gtkalignment.c docs/Changes-2.0.txt:
            Make these widget's init functions call
            gtk_widget_set_redraw_on_allocate(widget,FALSE).
    
            * gtk/gtkwindow.c (gtk_window_configure_event): Call
            _gtk_container_queue_resize(), since we don't want
            redrawing. (Probably could be done for other
            calls to gtk_widget_queue_resize() in gtkwindow.c,
            but this is the most important one.)
    
            * gtk/gtkwindow.c (gtk_window_move_resize): Don't call
            gtk_widget_queue_draw() - size_allocate() handles
            that as appropriate.
    
            * gtk/gtkframe.c (gtk_frame_size_allocate): Invalidate instead
            of queue_clear() to avoid invalidating children.
