2003-11-13T10:19:27
* docs/CHANGES: Updated. Handle SETWIDTH_NAME and ADD_STYLE_NAME properties for BDF and PCF fonts. * src/bdf/bdfdrivr.c (bdf_interpret_style): New auxiliary function. (BDF_Face_Init): Don't handle style properties but call bdf_interpret_style. * src/pcf/pcfread.c (pcf_interpret_style): New auxiliary function. (pcf_load_font): Don't handle style properties but call pcf_interpret_style.
