  14 %       Using a zero value radius for an ellipse or an arc would result
  15 %               in a non-invertible CTM matrix which causes problem when this
  16 %               when this PostScript is wrapped inside other routines, such as
  17 %               the multi.ps package from
  18 %               ftp.ucc.su.oz.au:/pub/ps_printing/multi.  You can overcome such
  19 %               error by uncommenting the sole line of the procedure below:
