        * reworked the redrawing heuristics somewhat, this fixed a bunch of
        existing redrawing problems and majorly reduces overall redrawing needs
        during normal operation. basically we now only queue redraws when
        neccessary and much rely on the draw_area coalescing code in gtkwidget.c
        to optimize the queued portions. widgets will now upon reallocation only
        get redrawed if their allocation has changed. upon hide/show only the
        area allocated by the child will be queued for the parent, this has the
        side effect that parents which change their appearance in dependance on
        the numer of visible children have to keep track of their children's
        visiblity and eventually fully redraw themselves. this is a minor
        constrain with great benefits in terms of redraw reduction, and only got
        triggered by the notebook widget.

        * gtk/gtkwidget.c:
        (gtk_widget_queue_clear): don't bother if width and height == 0.
        (gtk_widget_queue_clear_child): new static function to queue a redraw of
        the area obscured by a child on a parent.
        (gtk_widget_queue_resize): queue_clear the widget if it is drawable.
        (gtk_widget_show): queue resize on the widget before showing.
        (gtk_widget_hide): queue resize on the widget after hiding.
        (gtk_widget_map): queue_draw the widget after mapping.
        (gtk_widget_unmap): queue_clear_child the widget.
        (gtk_widget_size_allocate): queue_clear_child and queue_draw if the
        widget's allocation changed.
        (gtk_widget_unparent): queue_clear_child so the parent redraws obscured
        portions.
        (gtk_widget_real_show):
        (gtk_widget_real_hide):
        (gtk_widget_real_map):
        (gtk_widget_real_unmap):
        (gtk_widget_real_size_allocate): don't bother with redraw queueing,
        descendants that override these functions don't do either and we handle
        all redrawing/resizing related stuff before or after the signal emission
        now.

        * gtk/gtkcontainer.c:
        (gtk_container_resize_children): don't bother about redrawing anymore
        since gtk_widget_size_allocate handles that for us now.

        * gtk/gtknotebook.h:
        * gtk/gtknotebook.c:
        added a flag have_visible_child to indicate whether we need to draw
        non child related portions at all, e.g. shadows etc.
        (gtk_notebook_draw): if have_visible_child changed, do a full paint
        instead of updating a small area only.

Mon Jan 11 20:44:35 1999  Tim Janik  <timj@gtk.org>

        * gtk/gtkstyle.c: changed gtk_style_apply_default_pixmap to
        gtk_style_apply_default_background which takes an extra argument
        copy_area to determine NO_WINDOW widget pixmap copying.
        changed callers accordingly.

        * gtk/gtktogglebutton.c:
        (gtk_toggle_size_allocate):
        (gtk_toggle_button_expose):
        (gtk_toggle_button_paint): avoid messing with our parent's window if
        toggle_button->draw_indicator == TRUE and we are a NO_WINDOW widget.

        * gtk/gtkcheckbutton.c (gtk_real_check_button_draw_indicator): draw
        the draw_indicator with GTK_STATE_ACTIVE if the toggle button is active.

        * gtk/check-n.xpm:
        * gtk/check-y.xpm:
        * gtk/testgtkrc: set pixmaps for ACTIVE and NORMAL check button
        bg_pixmaps.
