- Variations font support now takes care of the `MVAR' table also.
II. MISCELLANEOUS
- A new function `FT_Set_Default_Properties' has been added to
parse the `FREETYPE_PROPERTIES' environment variable
(previously, it was internal only). `FT_Init_FreeType' always
call this function, but `FT_New_Library' does not (similar to
`FT_Add_Default_Modules').
