Thanks for working on this. Looks good so far (though I haven't tested 
in any real depth).

The one thing I don't see here is any support for the Hangul one- and 
two-dot tone marks U+302E/302F. It's possible some fonts could handle 
these entirely within OpenType, but in the case of Windows' malgun.ttf, 
for example, we need to re-order the tone mark to precede the syllable 
to which it is applied, so that it appears on the left.

I believe both Uniscribe and Core Text handle this, so we really need to 
match their behavior.
