Pushing this out early to catch bot errors since I'm using template tricks
we were not using in HarfBuzz before.

See https://github.com/behdad/harfbuzz/pull/590#issuecomment-341194673.

I simply removed the composite glyph and use the referenced simple
glyph directly.

This reverts commit 70137e2b.

Freetype and OT font functions give different positions for some glyphs
in this font (OT seems to be correct), but that is not what we are
interested in in this test.

See https://github.com/behdad/harfbuzz/pull/590#issuecomment-341045223.

These are CFF fonts and ot functions don’t support CFF glyph names yet.
The next commit will run all tests with ot functions.

Might help with https://github.com/behdad/harfbuzz/pull/592
Ie. bringing in qsort_r() prototype always.
