We need the computed standard horizontal and vertical widths for the emboldening calculation. This method provides a convenient way to extract it from writing-system-specific metrics structures, which all script definitions must implement. * src/autofit/aftypes.h (AF_WritingSystem_GetStdWidthsFunc): New function type. (AF_WritingSystemClassRec): New member `style_metrics_getstdw'. (AF_DEFINE_WRITING_SYSTEM_CLASS): Updated. * src/autofit/afcjk.c (af_cjk_get_standard_width): New function. (af_cjk_writing_system_class): Updated. * src/autofit/afdummy.c (af_dummy_writing_system_class): Updated. * src/autofit/afindic.c (af_cjk_get_standard_width): New function. (af_indic_writing_system_class): Updated. * src/autofit/aflatin.c (af_latin_get_standard_width): New function. (af_indic_writing_system_class): Updated. * src/autofit/aflatin.c (af_latin_get_standard_width): New function. (af_indic_writing_system_class): Updated.
