/**
 * Example application that demonstrates a multiple level layers within a
 * single viewport. One object is placed in each layer and it
 * should show the two objects with the front layer always rendered in front
 * of the background layer. The front layer is fixed, but the back layer
 * animates in such a way that, if both objects were in the one scene, it
 * would move in front and then behind it.
