Public Sub Move( _
   ByVal Index As Long, _
   ByVal Destination As Long _
) 

By using Move, Labels may be re-ordered within the collection.  The Label referred to by the index is placed at the position given by "destination", other Labels being kept in sequence but moved as necessary to accommodate the moved item.
The main need for this method is when labels overlap, as those later in the collection are drawn last, possible over-writing parts of earlier labels.
