freetype/src/cff/cffdrivr.c
Werner Lemberg 0b3cb8a8af [cff, truetype] Fix logic for `FT_Property_Set'. 
Otherwise some properties could be set to arbitrary values, which is
harmless, but querying could give wrong positive results.

* src/cff/cffdrivr.c (cff_property_set) [hinting-engine],
* src/truetype/ttdriver.c (tt_property_set) [interpreter-version]:
Only allow defined values.
