The docs say that the bearings are defined by CBox ( http://www.freetype.org/freetype2/docs/glyphs/glyphs-3.html) and this is what the code in cffgload.c does for horizontal layout. I do not understand why it gets crafty for vertBeraingX and forgets about vertBearingY altogether. I would just set it to CBox values according to the definition, but I sense a trap because the pictures in the doc show that the origin is different for different layouts. Does CBox depend on the layout as well? It looks like it should. Thoughts?
