While fixing an unrelated bug, I realized that our current technique of
determining a X/Y translation before flush time, and then applying it during the
flush, is actually incorrect with respect to reordering.  This bug hasn't shown
up in the wild(AFAIK).  This change moves the translation calculation change to
flush time.  This will, unfortunately, be less efficient than our earlier
incorrect solution.
