title: Convert Point coordinates to Screen coordinates in JavaFX?
body: <p>After looking through several SO posts I have still not found a satisfactory result. </p>
  
  <p>I have, as stated above, a Point and I need to convert it from local- to screen.
  When I worked in Swing the <code>SwingUtilities.convertPointToScreen</code> function would work fine but I am lacking a alternative in JavaFX.</p>
