Make the Wrapper object listen to the GM object and retrigger all events on
the Wrapper. For example:
function Shape() {
this.shape_ = new google.maps.Polygon(...);
var self = this;
google.maps.event.addListener(
this.shape_, 'click', function(e) {
google.maps.event.trigger(self, 'click', e);
});
...
}
