title: Stop a tween animation in tween.js and three.js
body: <p>I'm having trouble stopping a tween in three.js, using tween.js.
  The docs state to use <code>tween.stop()</code>, but that doesn't seem to work.</p>
  
  <p>Example here:
  <a href="http://jsfiddle.net/feLzjzy9/1/" rel="nofollow">http://jsfiddle.net/feLzjzy9/1/</a></p>
  
  <p>As you hover with the mouse over a box, it starts to change color. This animation takes 10 seconds, but I try to stop it just to test the .stop() feature using <code>setTimeout(function(){ tween.stop() }, 1000);</code>but it doesn't do a thing...</p>
  
  <p>Any help is much appreciated!</p>
