        src/truetype/ttinterp.c, src/truetype/ttobjs.c, src/truetype/ttobjs.h:

        changed the name of TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING to
        the simpler TT_CONFIG_OPTION_UNPATENTED_HINTING

        removed the macro TT_CONFIG_OPTION_FORCE_UNPATENTED_HINTING. Instead,
        the same effect can be used by setting a debug-hook with
        FT_DEBUG_HOOK_UNPATENTED_HINTING globally with FT_Set_Debug_Hook()

only, then try to find a better hit by comparing pixel_width also.
Without this fix it isn't possible to access all strikes.
Also compute metrics.max_advance to be in sync with other bitmap
drivers.
