$DATA_MASKS
$DATA_MASKS :
See ISO 18004:2006 6.8.1
110: mask bits for which (xy mod 2 + xy mod 3) mod 2 == 0
Note that the diagram in section 6.8.1 is misleading since it indicates that i is column position and j is row position. In fact, as the text says, i is row position and j is column position.
