branch: master
commit bcae657482ca038dc2b7c4ddd737a110c85e052a
Author: Dave Arnold <address@hidden>
Commit: Werner Lemberg <address@hidden>
Add `FT_Get_Var_Design_Coordinates' function.
Note that the low-level functions aren't implemented yet.
* include/freetype/ftmm.h: Declare.
* include/freetype/internal/services/svmm.h
(FT_Get_Var_Design_Func): New typedef.
(MultiMasters): New MM service function `get_var_design'.
(FT_DEFINE_SERVICE_MULTIMASTERSREC): Updated.
Update all callers.
* src/base/ftmm.c (FT_Get_Var_Design_Coordinates): Implement.
* src/truetype/ttdriver.c: Updated.
* src/truetype/ttgxvar.c (TT_Get_Var_Design): New dummy function to
handle `get_var_design' service.
* src/truetype/ttgxvar.h: Updated.
* src/type1/t1driver.c: Updated.
* src/type1/t1load.c (T1_Get_Var_Design): New dummp function to
handle `get_var_design' service.
* src/type1/t1load.h: Updated.
