            * gtk/gtkwidget.c (gtk_widget_hide): !GTK_OBJECT_DESTROYED() ->
            GTK_WIDGET_REALIZE() for resize queueing.
            * gtk/gtkmain.c (gtk_main_do_event): !GTK_OBJECT_DESTROYED() ->
            GTK_WIDGET_REALIZE() for post event delivery destruction upon
            * gtk/gtkwidget.c: added GtkWidget::event-after notification signal, to
            sompensate for former (pre-2.0) connect_after() facility.
            (gtk_widget_event): assert the widget is realized, since event delivery
            to non-realized widgets is essentially a bug. event handlers should
            be able to unconditionally rely on widget->window (unless they
            emit events on their own which can trigger widget destruction).
            (gtk_widget_event_internal): removed old outdated GTK_OBJECT_DESTROYED()
            logic. event delivery happens as follows:
            a) emission of GtkWidget::event (RUN_LAST handler). returns was_handled.
            b) if !was_handled in (a) and the widget is still realized, emit event-
               specific signal (RUN_LAST handler). returns was_handled.
            c) emission of GtkWidget::event-after for notification if the widget is
               still realized (regardless of was_handled from previous stages, no
               class handler). no return value.
            d) was_handled gets passed on to caller, to determine further
               propagation. if the widget got unrealized meanwhile, was_handled
               is returned as TRUE.
