title: Custom-shaped Aero glass window with WPF
body: <p>Is it possible to design a window in WPF that would allow an inner image to go over the borders of the aeroglass window?</p>
  
  <p>An example of this is the Start Menu in Windows 7:</p>
  
  <p><img src="https://i.stack.imgur.com/wauc4.png" alt="overglass"></p>
  
  <p>On this image the user icon is not within the borders of the aeroglass start menu window, but overlaps it. </p>
  
  <p>How did MS achieve this?</p>
  
  <p>My guess: those are two separate windows, stacked on top of one another? </p>
