     * 
     *  <p>In alpha mode, the opacity of each pixel in the source content is multiplied by the opacity 
     *  of the corresponding region of the mask.  i.e., a pixel in the source content with an opacity of 

     *  mask clips the masked content. This property can 
     *  only have an effect if the graphic element has a 
     *  mask applied to it that is of type 
     *  <code>MaskType.LUMINOSITY</code>.
