title: ActionScript - Tween With Zero Duration?
body: <p>i have a tween function which fades in a display object over time.</p>
  
  <p>when i set my tween duration to 0 nothing happens.  isn't the tween suppose to animate in 0 seconds (or frames) to emulate no animation at all?</p>
  
  <pre><code>new Tween(this, "alpha", None.easeOut, 0.0, 1.0, 0, true);
  </code></pre>
