* src/autofit/aflatin.c, src/autofit/afhints.c: changed the
implementation of the LIGHT hinting mode to completely disable
horizontal hinting. This is an experimental effort to integrate
David Chester's latest patch without fucking the other hinting
modes as well.
Note that this doesn't force auto-hinting for all fonts however.
