title: Catch bounds_changed event when user moves the map but not the setCenter method
body: <p>I want to listen 'bounds_changed' event when the user moves the map, changes the zoom but I don't want it to be fired when my program calls setCenter or setZoom methods. So I tried removing event before setting center and adding it after, again. However, it didn't worked, My event is still being fired.</p>
  
  <pre><code>var currentBoundsListener = null;
  
  function addBoundsChangedListener() {
      currentBoundsListener = google.maps.event.addListener(map, 'bounds_changed', function () {
          // Whatever.
      });
  }
  
  function setCenter(lat, lng) {
      google.maps.event.removeListener(currentBoundsListener);
      var geo = new google.maps.LatLng(lat, lng);
      map.setCenter(geo);
      addBoundsChangedListener();
  }
  </code></pre>
  
  <p>I think the map is creating bounds_changed event after I add the new listener to it, like the event is asynchronised.</p>
