  [truetype, cff] Extend `get_var_blend' function of MM service. In particular, we need access to named instance data. * include/freetype/internal/services/svmm.h (FT_Get_Var_Blend_Func): Add argument for `FT_MM_Var'. * src/cff/cffload.c (cff_get_var_blend): Updated. * src/cff/cffload.h: Updated. * src/cff/cf2ft.c (cf2_getNormalizedVector): Updated. * src/truetype/ttgxvar.c (tt_get_var_blend): Updated. Accept value `NULL' for arguments. * src/truetype/ttgxvar.h: Updated.
