I think it won't, since this is a limitation of the various
OpenType implementations and not of the specification itself.
I have some doubts. This is a limitation of the OpenType
specification, since IMHO it can not really handle CFF data with
more than one font.
How do you associate, as
FreeType2 support these operators:
# 0x010f: -Reserved- # XXX force_bold_threshold for FreeType2
# 0x0110: -Reserved- # XXX lenIV for FreeType2, Type 1 fonts
# 0x0118: -Reserved- # XXX multiple_master for FreeType2
# 0x0119: -Reserved- # XXX blend_axis_types for FreeType2
