/*
 PdMarker

 Purpose: extends Google Map API GMap and GMarker (hover effects, image swapping, moving)
 Details: http://wwww.pixeldevelopment.com/pdmarker.asp
 Updated: [see getPdMarkerRevisionInfo]
 Author:  Peter Jones
 Notes:   Relies on undocumented features of the Google Map API which may change.
	    Based on my own PJToolTip and ideas from GxMarker, TLabel and the Google Maps API forum.
