tdf#111967 translate offsets so it is relative to v origin
The offsets were 0 in HarfBuzz 1.3.3 but the value became
something else and made text offsets toward upper-right
after upgrading to HarfBuzz 1.4.8. Those values are offsets
relative to the horizontal origin. But underlying renderer
expect positionos relative to the vertical origin. Translate
them back by adding the horizontal origin.
