Directly compute glyphToUnicode array in DirectWrite.
This new code is still rather bad, but has fewer steps.
The motivation for looking at this is that on Windows 8 the previous code
was occasionally asserting in such a way as to imply that GetGlyphIndices
might return different data the second time through the font. This avoids
that particular issue by only going through the font once.
