My purpose is not to decompose. I could decompose outside cw_defroi (and
then my problem is I can not distinguish between (127,2) from (12,72) when I
have xy=1272). I was looking for the place where cw_defroi 'composes' xy
and, avoiding composition, making it two separate variables or one variable
with two dimensions.
