title: JavaFX: How to connect two Nodes by a Line?
body: <p>I want to connect two <code>Node</code>s with a <code>Line</code> (from center of the first to the center of the second).</p>
  
  <p>Initial thoughts:</p>
  
  <ul>
  <li>It is assumed that both nodes exist somewhere in the scene graph</li>
  <li>The <code>Line</code> acts as a decorator and should not be pickable</li>
  <li>If the <code>Node</code>  <code>Bounds</code> change, the <code>Line</code> should be updated</li>
  </ul>
  
  <p>It looks like I will need some compound property bindings including the proper coordinate space transformations.</p>
  
  <p>How to achieve this? Can anyone point out a direction?</p>
