* src/cff/cffgload.c (cff_slot_load): Scale `vertBearingY`.
Towards the end of the the function there is a call to
`FT_Outline_Get_CBox` that retrieves the glyph bbox in scaled units.
That sets `horiBearing{X,Y}` and `vertBearingX` but `vertBearingY`
is left alone, and is not scaled.
Patch from Eric Muller <emuller@amazon.com>.
