mf2pt1: Restoring mfplain defaults

 
 2.5 Restoring 'mfplain' defaults
 ================================
 
 'mf2pt1' normally redefines *filldraw* as *fill* and *unfilldraw* and
 *unfill* because Type 1 fonts don't allow overlapping curves.
 Similarly, 'mf2pt1' redefines *pencircle* as a 20-gon to coerce MetaPost
 into drawing it using a filled instead of a stroked PostScript path.
 
    If you know you'll be postprocessing your fonts using FontForge,
 which can automatically convert overlapping paths to nonoverlapping
 paths, then you can restore the original 'mfplain.mp' definitions of
 *filldraw*, *unfilldraw*, and *pencircle* as follows:
 
      if known ps_output:
        pencircle := mfplain_pencircle;
        let filldraw := mfplain_filldraw;
        let unfilldraw := mfplain_unfilldraw;
