No. It's not related. I just want to point you to the warper that
does try to micro-optimize the horizontal positioning of a glyph.

Yes.

Correct. It would be possible to adapt and re-use the warper code for
non-integer positioning. Whether this is useful, beautiful, fast
enough, etc., etc., is another issue.
