FX 8 3D: dirtyopts doesn't work for 3D rendering

Currently we need to set prism.dirtyopts=false for 3D to render correctly. At present, pretty much all 3D programs have this property set to false in the main block as a temporary workaround:

   public static void main(String[] args) {
       System.setProperty("prism.dirtyopts", "false");
       launch(args);
   }

However, with the switch to JDK8, this code no longer get executed. We need to fix this bug sooner than later.
