With the .addAll() method, this changes to become left to right, so the objects added first (left) are
on the bottom of the compositing layer stack. A new addNodesToStackPane() method structure using
.getChildren().addAll() method calls would therefore look like the following, as shown highlighted at the
bottom of Figure 9-19:

private void addNodesToSCeneGraph() {
root.getChildren().addAll(gameBoard, uiLayout);
uiLayout.getChildren().addAll(boardGameBackPlate, logoLayer, infoOverlay, uiContainer);
uiContainer.getChildren().addAll(gameButton, helpButton, legalButton,
creditButton, scoreButton);
infoOverlay.getChildren().addAll(playText, moreText);
}

UI branch
