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. (pcf_property_set, pcf_property_get): New functions. (pcf_service_properties): New service. (pcf_servives): Updated. (pcf_driver_init) [PCF_CONFIG_OPTION_LONG_FAMILY_NAMES]: Handle `no_long_family_names'. * src/pcf/pcfread.c (pcf_load_font): Handle `no_long_family_names' and PCF_CONFIG_OPTION_LONG_FAMILY_NAMES. * docs/CHANGES: Updated.
