title: Google Maps API v3 'dragend' event fires before maps finishes sliding
body: <p>I have noticed that when you drag the map, if you drag with an accelerating movement, after you release the mouse, the map has some sort of momentum and it keeps sliding for a short period of time, but the 'dragend' event is fired when you release the mouse (which to me it seems correct).</p>
  
  <p>But how can you get the exact moment when the maps finishes SLIDING? I'm not interested in 'center_changed' / 'bounds_changed' solutions, because I need to make a XHR request on the event, and process some data.</p>
