title: What the easiest way to animate a Path as an object traverses it?
body: <p>Consider a rectangle traversing a long, linear path. It would be useful to figure out where the shape had gone earlier in the animation. Displaying the entire path before the shape moves is not what I want. That is easily done by adding the path to the pane. </p>
  
  <p>I want a trailing line behind the shape representing the path that the shape has traversed through so far. Does anyone know how to do this in Javafx? I am using Path and PathTransition to animate my object along a path.</p>
