+Draw a selection rectangle underneath the text as used e.g.

+are \texttt{wxCONTROL\_SELECTED} for items which are selected
+(e.g. often a blue rectangle) and \texttt{wxCONTROL\_CURRENT}
+for the item that has the focus (often a dotted line around
+the item's text). \texttt{wxCONTROL\_CURRENT} may be used
+to indicate if the control has the focus (othewise the
