In Java 3D 1.2, the only way to modify the texture is by creating a new
ImageComponent2D object, as you describe. It is not legal to modify
the BufferedImage directly. In Java 3D 1.3, we are adding updateData
methods to ImageComponent{2D,3D} and a new ImageComponentUpdater object
that will allow you to modify all or part of a BufferedImage in place.
