title: Remove filter attribute after jQuery UI dialog is finished opening
body: <p>Using jQuery UI 1.8rc3 combined with the new <code>jquery.effects.fade.js</code> code, I've been able to finally apply fade-in and fade-out effects to opening the UI Dialog widgets.  Hooray!</p>
  
  <pre><code>$dialog.dialog({
          show: { effect: "fade", options: {}, speed: 150 }
  }
  </code></pre>
  
  <p>This works great - unfortunately, <a href="https://stackoverflow.com/questions/411058/ie-is-losing-cleartype">there's the known IE7 &amp; 8 bug</a> where the ClearType gets turned off by the application of an empty <code>filter:</code> style attribute after the fade effect is finished.</p>
  
  <p>I have the code to remove the filter attribute, I just can't find a good way to hook it into the event chain. The dialog's "open" and "focus" events are too soon.  I need something like a "dialog opening animation is finished" callback.</p>
  
  <p>How can I hook up a callback to the end of the opening effect for a dialog?</p>
