The change from 2016-09-29 was too radical (except for people using
the openSuSE GNU/Linux distribution). To ameliorate the situation,
PCF_CONFIG_OPTION_LONG_FAMILY_NAMES gets introduced which controls
the feature; if set, a new PCF property option
`no-long-family-names' can be used to switch this feature off.
* include/freetype/config/ftoption.h, devel/ftoption.h
(PCF_CONFIG_OPTION_LONG_FAMILY_NAMES): New option.
* include/freetype/ftpcfdrv.h: New header file (only containing
comments currently, used for building the documentation).
* include/freetype/config/ftheader.h (FT_PCF_DRIVER_H): New macro.
* src/pcf/pcf.h (PCF_Driver): Add `no_long_family_names' field.
* src/pcf/pcfdrivr.c: Include FT_SERVICE_PROPERTIES_H and
FT_PCF_DRIVER_H.

and PCF_CONFIG_OPTION_LONG_FAMILY_NAMES.
* docs/CHANGES: Updated.
* include/freetype/internal/tttypes.h (TT_FACE_FLAG_VAR_XXX):
Remove all flags related to MVAR; replace it with...
(TT_FACE_FLAG_VAR_MVAR): ...this new macro.
(TT_Face): Remove `mvar_support' field (which was still unused).
* include/freetype/internal/tttypes.h (TT_FACE_FLAG_VAR_XXX):
New macros describing available functionality of various OpenType
tables related to font variation.
(TT_Face): New fields `variation_support' and `mvar_support',
replacing and extending `use_fvar'.

field.

In particular, we need access to named instance data.

code.
* include/freetype/internal/tttypes.h (TT_Face): Move
`is_default_instance' into TT_CONFIG_OPTION_GX_VAR_SUPPORT
block.
