It might be convenient to have a boolean on the scene to indicate 
whether it should be retained, but we don't plan any improvements to 3D 
in JDK 10 (which would be the absolute earliest such a change could 
happen). It seems it would be just as easy for an application to add a 
white point light at the camera, and that wouldn't have to wait until 
new API was added.
