title: Google Maps api v3 polygon edit event not fired on all handles
body: <p>I have a drawingManager that allows the user to draw a polygon. When the user is done drawing that polygon, I calculate the area of that polygon. All of this works perfectly except for editing the polygon event handling. I use the following code</p>
  
  <pre><code>google.maps.event.addListener(path, "set_at", function(){
      //my code here
  });
  </code></pre>
  
  <p>So this sort of works but only works for the "corners" of the polygon. There are intermediary, barely visible edit handles (squares) in between the main white handles. If I edit the polygon by pulling one of these handles, the event does not fire.</p>
  
  <p>Any ideas on this behavior? Is this intended or some sort of bug with the api or my code?</p>
  
  <p>Thank you for any help.</p>
