Somebody more knowledgeable can correct me, but I think combining diacritics happens with:
Outline1 -> hinted bitmap1
Outline2 -> hinted bitmap2
Bitmap output = hinted bitmap1 + hinted bitmap2 positioned at grid-fitted (ie another "hinting") offsets
(Actually, I think it happens in the opposite order: the grid-fitted offsets are calculated first)
compared to a single glyph with two sets of outlines, where the outlines are hinted together.
