* src/autofit/aflatin.c, src/autofit/afwarp.h, src/autofit/afwarp.c, src/autofit/aftypes.h, src/autofit/afloader.c, src/autofit/autofit.c: adding experimental implementation of "warp hinting" (new hinting algorithm for gray-level and LCD rendering). It is disabled by default, you need to #define AF_USE_WARPER in aftypes.h to enable it.
