connect to the widget's "expose_event" signal with
g_signal_connect_after() so that your handler is called after the
widget has drawn itself and draw your rectangle in the event handler.
As a trivial optimization you should probably respect the exposed area
and only draw the parts of the rectangle that are inside that area.
