[HarfBuzz] How to get hb_face_t and hb_font_t without Freetype?

And one more question. The shaping example in the HarfBuzz docs does
this after shaping:
x_offset = glyph_pos[i].x_offset / 64.0;
y_offset = glyph_pos[i].y_offset / 64.0;
x_advance = glyph_pos[i].x_advance / 64.0;
y_advance = glyph_pos[i].y_advance / 64.0;
Where do those 64.0 factors come from? IOW, I guess the question is
in what units are the members of hb_glyph_position_t measured, and how
to scale that to the pixels of the display?
