The definitive solution to your problem is to extend the Polyline class
defining the getPosition method.
This is a very simple implementation which returns the first point,
google.maps.Polyline.prototype.getPosition = function() {
return this.getPath().getAt(0);
}
maybe someone wishes to write a more sophysticated algoritm to compute the
central point of the line or the centroid of its enclosing polygon or
whatever. It won't be that easy, but is a well known GIS algorithm.
Cheers, Davide
PS The same is true for Polygon.
