title: Allow button click through layer in Flash/ActionScript3
body: <p>I have the following layer structure in Flash:</p>
  
  <ul>
  <li>Spotlight - Has a transparent center area, is a bitmap symbol</li>
  <li>Button</li>
  </ul>
  
  <p>How do I make <code>Button</code> clickable even though the <code>Spotlight</code> layer? I want to toggle the visibility of the <code>Spotlight</code> layer with the click of <code>Button</code> like the following code.</p>
  
  <pre><code>Button.addEventListener(MouseEvent.MOUSE_CLICK, OnClick);
  
  function OnClick(e:MouseEvent):void
  {
     Spotlight.visible = !Spotlight.visible;
  }
  </code></pre>
