* 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.
