You add it to the map here:
polyShape = new GMarker(polyPoints)
both polygonMode and polylineMode are false, polyPoints is not a
GLatLng so the API gets confused and displays it in the upper left
hand corner.
This is the one that is in the correct place:
marker = new GMarker(polyPoints[polyPoints.length -1]);
