I have to explain that I do intend to use the OT shaper, but I just
want to have the font table data loaded from a CGFontRef instead.

I do get some valid glyph ids when I force it to use coretext_aat
shaper (but not coretext shaper, what's the difference?) But when I
force it to use ot shaper I got nothing but the bounding boxes.
(coretext_aat however, get all 0 for the bounding boxes, which makes
it even weirder.)

I haven't been working on this for a while so I'm really curious how
these pieces are supposed to fit (for instance I saw tests call
hb_ft_set_font_funcs(), but I don't want to depend or use any FreeType
APIs on Mac, is that possible?). Would be nice if someone can
enlighten me.
