Rather than creating a new PangoContext each time the menu redraw
handler is triggered re-use it if one was created previously.
All toytoolkit clients do create a layout (and implicitly a
PangoContext) but only those that have menu redraw
handler installed will create a new layout for each redraw of the menu,
effectively creating a new PangoContext each time.
