Hi Kevin

It was not the Scene I am concerned about. It was the backing
rectangle for a MediaView. It is like put a 3D plane on another plane,
really. What is the Z order for the two planes rotated in 3D space? I
expected the black bars on each CubeFace to appear just on a TV when
the television station broadcasts a movie of 21:9 ratio when most home
HDTVs are 16:9. So I guess I thinking about this wrong.

This is the Scala / JavaFX code
http://code.google.com/p/scalafx/source/browse/demo/scalafx/graphics3d/VideoCubeDemo.scala

If I set the Rectangle DepthTest to DISABLED then the result is worst.
The starry background appears through the backing rectangles.

The other thing that occurred in my mind is just to disable the
preserveRatio and that would solve it, although the aspect ratio would
be destroyed.
