Hi,
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.

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?
