But that doesn't have per-character metrics such as the width of a

Correct, but values in FT_FaceRec are always global.  Glyph metrics
are available in FT_GlyphSlot -> metrics.

I'm still confused. FT_GlyphSlot and FT_Size are in the "scaleable outlines"
part of FT_FaceRec, but a bitmap font is not a scaleable outline.

In struct FT_FaceRec, does the comment only apply to bbox, or to all
the other members following too?

For all the following members.  Note that FT_Size_Metrics are set for
bitmap fonts also.

So that means even tho FT_FaceRec -> size and FT_FaceRec -> glyph are in
the "scaleable outlines" section of FT_FaceRec, they are used for non-scaleable
(bitmap) fonts too?
