/**
 * This interface is designed to be an optional additional API supported by
 * some implementations of {@link java.awt.Image} to allow them to provide
 * alternate images for various rendering resolutions. The various
 * {@code Graphics.drawImage(...)} variant methods will consult the methods
 * of this interface if it is implemented on the argument {@code Image} object
 * in order to choose the best representation to use for each rendering operation.
 * <p>
 * The {@code MultiResolutionImage} interface should be implemented by any
 * subclass of {@code java.awt.Image} whose instances are intended to provide
 * image resolution variants according to the given image width and height.
 * For convenience, toolkit images obtained from
 * {@code Toolkit.getImage(String name)} and {@code Toolkit.getImage(URL url)}
 * will implement this interface on platforms that support naming conventions
 * for resolution variants of stored image media and the
 * {@code AbstractMultiResolutionImage} and {@code BaseMultiResolutionImage}
 * classes are provided to facilitate easy construction of custom multi-resolution
 * images from a list of related images.
 *
