    //			where nx = numXLevels(), and ny = numYLevels().
    //			In an individual level, (lx, ly), the tiles
    //			are stored in the following order:
    //
    //			    (0, 0)   (1, 0)   ... (tx-1, 0)

    //
    //	 DECREASING_Y   As for INCREASING_Y, the tiles for each level
    //			are stored in a contiguous block.  The levels
    //			are ordered the same way as for INCREASING_Y,
