 * This class extends {@code DataBuffer} and stores data internally as

 * Note that some implementations may function more efficiently
 * if they can maintain control over how the data for an image is
 * stored.
 * For example, optimizations such as caching an image in video
 * memory require that the implementation track all modifications
 * to that data.
 * Other implementations may operate better if they can store the
 * data in locations other than a Java array.
 * To maintain optimum compatibility with various optimizations
 * it is best to avoid constructors and methods which expose the
 * underlying storage as a Java array as noted below in the
