title: Prevent an instance of NSView from receiving mouse events
body: <p>I have an NSView in a window with core animation layer turned on.
  I use this view to display images with animation from time to time. I need the entire view to be the back layer not only the images. Behind this view which I call AnimationBaseView are other views which the user interacts to. </p>
  
  <p>Everything is ok except the AnimationBaseView prevents the other views from getting rightMouseDown events.</p>
  
  <p>I've tried the following:</p>
  
  <ul>
  <li>returning NO to acceptsFirstResponder to AnimationBaseView</li>
  <li>Hiding and unhiding the AnimationBaseView as needed, but produces a nasty flicker.</li>
  </ul>
  
  <p>Thank you for your help,
  Jose.</p>
