 * The object tile layer class is a convenience class provided to simplify
 * the management of a two-dimensional array of object tiles. It takes
 * care of dereferencing the tile array efficiently with methods that the
 * Java compiler should inline, and prevents the caller from having to do
 * the indexing multiplication by hand every time.
 *
 * <p> This is equivalent to {@link TileLayer} except that it contains
 * {@link ObjectTile} instances. For efficiency's sake, we don't extend
 * that class but instead provide a direct implementation.
