Hi Han,

For the xBAYROFF keywords, is it just a transformation of the superpixel orientation, or is there an actual "shift" involved? And their application is just a transform of the superpixel in x/y if odd, no change if even?

Are the keywords ever used together (and with ROWORDER), and if so is there an application order?
