title: createjs.Shadow alpha
body: <p>Can the alpha of a drop shadow created with createjs.Shadow be controlled independently of the object it's attached to? I tried, simply:</p>
  
  <pre><code>myObject.shadow = new createjs.Shadow("#000000",200,200,15);
  myObject.shadow.alpha=0.2;
  </code></pre>
  
  <p>But that's a no go. Can't find anything in the API docs, but those are all pretty damn confusing to begin with.</p>
