/**
 * This class is an array-based implementation of
 * the {@code AbstractMultiResolutionImage} class.
 *
 * This class will implement the
 * {@code getResolutionVariant(double destImageWidth, double destImageHeight)}
 * method using a simple algorithm which will return the first image variant
 * in the array that is large enough to satisfy the rendering request. The
 * last image in the array will be returned if no suitable image is found
 * that is as large as the rendering request.
 * <p>
 * For best effect the array of images should be sorted with each image being
 * both wider and taller than the previous image.  The base image need not be
 * the first image in the array. No exception will be thrown if the images
 * are not sorted as suggested.
