title: How can I resize ImageView to window with only Scene Builder
body: <p>Is it possible to resize a ImageView node (child of AnchorPane) to the window size by only using Scene Builder? The only way I found was binding width/height properties of the ImageView to the window width/height properties. 
  This would work for my purpose but I would like to keep the design inside the fxml file and no little bits of code here and there to fix the layout.
  I hope someonr can help me out</p>
