Forgive me if I misunderstand, but your
0001-truetype-Correctly-reset-point-tags-for-glyph-compon.patch fixes
one issue, in that the circumflex for glyph #2171 was half 'high' and
half 'low' when hinted. After applying the patch, the circumflex is
entirely 'low', the same as glyph #733, but that still looks wrong to
me (when comparing hinted vs unhinted). In other words, the problem I
noted in the original post I made 7 days ago still isn't fixed, and
that's the thing we're waiting for a response from Microsoft, right?
