The confusion comes from the fact that Jonathan seems to be writing a
glyph rendering library. From his perspective, yes, you need to add
offsets to bearings to position the black bits of a glyph correctly. All
completely correct.

The *problem* comes from the fact that he's mixing layers and using
Harfbuzz inside his glyph rendering library, which is totally not where
it should be used.
