  * src/otlayout/otlayout.h, src/otlyaout/otlconf.h, src/otlayout/otlgsub.c, src/otlayout/otlgsub.h, src/otlayout/otlparse.c, src/otlayout/otlparse.h, src/otlayout/otlutils.h: updating the OpenType Layout code, adding support fot the first GSUB lookups. Nothing that really compiles for now though * src/autohint/ahhint.c: disabled serif stem width quantization. It produces slightly better shapes though this is not distinguishable with many fonts.
