verticalOrigin

The vertical origin of the glyph relative to its origin, in pixels with y pointing down: the point of the glyph that is placed on the vertical line, centered on the glyph and usually above the baseline. In vertical text a glyph is drawn at the pen position minus its vertical origin. From VORG, or from vmtx and the bounds of the glyph, or, when the font has no vertical metrics, centered on the verticalAdvance.
