 * This class defines a 3D image component.  This is used for texture
 * images.
 * Prior to Java 3D 1.2, only BufferedImage objects could be used as
 * the input to an ImageComponent3D object.  As of Java 3D 1.2, an
 * ImageComponent3D accepts an array of arbitrary RenderedImage
 * objects (BufferedImage is an implementation of the RenderedImage
 * interface).  The methods that set/get a BufferedImage object are
 * left in for compatibility.  The new methods that set/get a
 * RenderedImage are a superset of the old methods.  In particular,
 * the two set methods in the following example are equivalent:
 *
 * 
 * 

 * 
 * BufferedImage bi;

 * RenderedImage ri = bi;

 * ImageComponent3D ic;

 * 
 * // Set image 0 to the specified BufferedImage

 * ic.set(0, bi);

 * 
 * // Set image 0 to the specified RenderedImage

 * ic.set(0, ri);
