title: EaselJS: Cannot get BitmapAnimation to display on stage
body: <p>I'm trying to draw an animated bitmap on my stage but I can't seem to get it working. I can verify the animation is added to the stage in the console but it's not displaying.</p>
  
  <p>HTML:</p>
  
  <pre><code>&lt;canvas id="canvas" width="300" height="300"&gt;&lt;/canvas&gt;
  </code></pre>
  
  <p>JavaScript:</p>
  
  <pre><code>var canvas = document.getElementById('canvas'),
      stage = new createjs.Stage(canvas),
      chopperImg = document.createElement('img'),
      spriteSheet,
      animation;
  
  chopperImg.addEventListener('load', function ( e ) {
  
      spriteSheet = new createjs.SpriteSheet({
          images: [ chopperImg ],
          frames: { width: 64, height: 75, count: 10 },
          animations: {
              idle: [ 0, 9, 'idle', 4 ]
          }
      });
  
      animation = new createjs.BitmapAnimation(spriteSheet);
      animation.gotoAndPlay('idle');
  
      stage.addChild(animation);
  
      createjs.Ticker.setFPS(30);
      createjs.Ticker.addListener(stage);
  });
  
  chopperImg.src = 'http://dutchnoobz.nl/chopper.gif';
  </code></pre>
