  [type1,cff] Add FT_{Set,Get}_MM_WeightVector API calls. For multiple master fonts, common usage (in Postscript) is to modify the WeightVector of an existing font instance, this addition supports that use. * include/freetype/ftmm.h, src/base/ftmm.c (FT_Set_MM_WeightVector, FT_Get_MM_WeightVector): New API functions. * include/freetype/internalservices/svmm.h (FT_Set_MM_WeightVector_Func, FT_Get_MM_WeightVector_Func): New function types. (MultiMasters): Add `set_mm_weightvector' and `get_mm_weightvector' members. (FT_DEFINE_SERVICE_MULTIMASTERSREC): Updated. * src/cffcffdrivr.c (cff_set_mm_weightvector, cff_get_mm_weightvector): New functions. (cff_service_multi_masters): Register them. * src/truetype/ttdriver.c (tt_service_gx_multi_masters): Updated. This driver doesn't use the new interface. * src/type1/t1load.c (T1_Set_MM_WeightVector, T1_Get_MM_WeightVector): New functions. * src/type1/t1driver.c (t1_service_multi_masters): Register them. * src/type1/t1load.h: Updated.
