Warning
gtk_widget_queue_clear_area has been deprecated since version 2.2 and should not be used in newly-written code. Use gtk_widget_queue_draw_area() instead.
This function is no longer different from
gtk_widget_queue_draw_area(), though it once was. Now it just calls
gtk_widget_queue_draw_area(). Originally
gtk_widget_queue_clear_area() would force a redraw of the
background for GTK_NO_WINDOW widgets, and
gtk_widget_queue_draw_area() would not. Now both functions ensure
the background will be redrawn.
