[autofit] Add hinting direction to `AF_ScriptClassRec'. Still unused. * src/autofit/afglobal.c (SCRIPT): Handle hinting direction. * src/autofit/aftypes.h (AF_ScriptClassRec): Add `top_to_bottom_hinting' field. (AF_HINTING_BOTTOM_TO_TOP, AF_HINTING_TOP_TO_BOTTOM): New macros. (AF_DEFINE_SCRIPT_CLASS): Updated.
