I think we might want to file an RFE to improve this so that a user 
wouldn't have to create a JFXPanel first. It should be possible to 
detect whether AWT has been initialized already, and thus choose to 
initialize FX in the embedded mode behind the scenes (upon first 
Platform.invokeLater() call, for example, or we may even want to 
introduce a separate API for this kind of initialization).
