        Expose improvements for GtkNotebook. Bug #383435

        * gtk/gtknotebook.c (gtk_notebook_expose): propagate the event to tab
        labels.
        (gtk_notebook_draw_focus): do not repaint the whole focused tab again.
        (gtk_notebook_draw_tab): do not send handmade expose events to tab
        labels.
