body: <p>How can i implement a transparent panel with non-transparent children in JavaFX 2?
  The effect i want to achieve is for example applied to menus in Blender:</p>
  
  <p><img src="https://i.stack.imgur.com/xg4ni.png" alt="enter image description here"></p>
  
  <p>The menu-panel / window is transparent, but the text items are not transparent which leads to a pretty effect.</p>
