  [autofit] While tracing, report script names instead of ID values. * src/autofit/afglobal.c (af_script_names) [FT_DEBUG_LEVEL_TRACE]: New array. * src/autofit/afglobal.h: Updated. * src/autofit/afcjk.c (af_cjk_metrics_init_widths, af_cjk_hint_edges): Use `af_script_names'. * src/autofit/aflatin.c (af_latin_metrics_init_widths, af_latin_hint_edges): Ditto.
