Rendering in Epiphany

The vertical placement of glyphs seems to be applied wrongly, for example the Arabic glyphs in https://fonts.google.com/specimen/Aref+Ruqaa and https://fonts.google.com/specimen/Reem+Kufi has their dots moved incorrectly above or below the glyphs.

I suspect this is relative to the fact that in fonts Y moves up while in many graphical systems it moves down, so the Y positions returned from HarfBuzz need to be negated at some point.
