 /**
 * The base tile layer class is a convenience class provided to simplify
 * the management of a two-dimensional array of base 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 com.threerings.media.tile.TileLayer}
 * except that it contains {@link BaseTile} instances. For efficiency's
 * sake, we don't extend that class but instead provide a direct
 * implementation.
