* src/cff/cffgload.c: do not apply the font transform to loaded glyph
if it is the identity. this cuts a significant percent of CFF glyph
loading time
* src/autofit/afglobal.c: change default hinting script to
CJK, since it works well with a larger array of scripts. thanks to
"Rahul Bhalerao" <b.rahul.pm@gmail.com> for pointing this out !
