title: Why doesn't jQuery use requestAnimationFrame?
body: <p>Some browsers support <code>requestAnimationFrame</code>, so why not use it? After all, it's been <a href="https://developer.mozilla.org/en/DOM/window.mozRequestAnimationFrame#AutoCompatibilityTable">supported since Google Chrome 10</a>. Despite that, jQuery <a href="http://bugs.jquery.com/ticket/9717">does not seem to be using it</a>. I've found a <a href="http://bugs.jquery.com/ticket/9717">bug report</a> about it, but no real explanation was given? I'm sure the jQuery people have their reasons, though.</p>
  
  <p>Why wouldn't they use this awesome API?</p>
