title: Java transparent JFrame, JVLC and java.awt.Canvas
body: <p>I am trying to achieve an effect of transparent JFrame on top of video stream provided JVLC library.
  Background is an instance of java.awt.Canvas
  Foreground is my whatever JFrame with a couple of controls on it.</p>
  
  <p>rootPane.setForeground(myFrame);
  rootPane.setBackground(myCanvas);</p>
  
  <p>JVLC uses my canvas through JNA like this
  jvlc.setVideoOutput(myCanvas);
  jvlc.apply();</p>
  
  <p>I expect myFrame to be always transparent to myCanvas.
  Any ideas how to get this work?</p>
