     *
     *  <p>Clip Masking</p>
     * 
     *  <p>When masking in clip mode, a clipping masks is reduced to 1-bit.  This means that a mask will 
     *  not affect the opacity of a pixel in the source content; it either leaves the value unmodified, 
     *  if the corresponding pixel in the mask is has a non-zero alpha value, or makes it fully 
     *  transparent, if the mask pixel value has an alpha value of zero.</p>
     * 
     *  <p>Alpha Masking</p>
     * 
     *  <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 
     *  1 that is masked by a region of opacity of .5 will have a resulting opacity of .5.  A source pixel 
     *  with an opacity of .8 masked by a region with opacity of .5 will have a resulting opacity of .4.</p>
     * 
     *  <p>Luminosity Masking</p>
     * 
     *  <p>A luminosity mask, sometimes called a 'soft mask', works very similarly to an alpha mask
     *  except that both the opacity and RGB color value of a pixel in the source content is multiplied
