title: Crop image in flex using a non-rectangular shape
body: <p>I've been following this tutorial to crop images in flex: <a href="http://code.mediablur.com/ImageCropper/ImageCropperDemo.html" rel="nofollow noreferrer">http://code.mediablur.com/ImageCropper/ImageCropperDemo.html</a>.</p>
  
  <p>At the heart of its cropping is using a method called "copyPixels".  However, this method takes as one of its arguments a rectangular shape for its crop region.  Are there other strategies I can use to crop it not using a rectangle.  </p>
  
  <p>I am going after letting the user specify the region that should be cropped using a series of points.</p>
