Sun Nov  4 16:02:08 2001  Owen Taylor  <otaylor@redhat.com>

        * 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.
