title: How can I detect changes in zoom level?
body: <p>Open <a href="http://www.google.com/search?q=stack" rel="nofollow">this page</a> on Chrome or Safari and fiddle with the zoom level. You'll notice a cute easing effect on its elements when you change the zoom level.</p>
  
  <p>Apparently this only works on Chrome and Safari (webkit?), but how is this done? And is there a cross-browser way to do this?</p>
