That's odd, I think I'm getting the point positions (for the grid-fit
splines) directly from freetype. That is the intention at least

I don't have time to look at this now, I'll get back to you.

No. But if anyone can point me to docs for either Apple's or MS's
rasterizers I'd be happy to look into it -- I presume they won't provide
the access I need for debugging, but at the least there must be a way of
getting the final result...
