/*        Stroke character definitions

   The  following  character  definitions are derived from the (public
   domain) Hershey plotter  font  database,  using  the  single-stroke
   Roman font.

   Each  character  definition  begins  with 3 bytes which specify the
   number of X, Y plot pairs which follow, the negative  of  the  skip
   before  starting  to  draw  the  characters, and the skip after the
   character.  The first plot pair moves the pen to that location  and
   subsequent  pairs  draw  to  the  location given.  A pair of 192, 0
   raises the pen, moves to the location given by the following  pair,
   and resumes drawing with the pair after that.

   The  values  in  the  definition  tables are 8-bit two's complement
   signed numbers.  We  declare  the  table  as  "unsigned  char"  and
   manually  sign-extend  the  values because C compilers differ as to
   whether the type "char" is signed or unsigned, and  some  compilers
   don't  accept the qualifier "signed" which we would like to use for
   these items.  We specify negative numbers as their  unsigned  two's
   complements  to  avoid  complaints  from compilers which don't like
   initialising unsigned data with signed values.  Ahhh,  portability.
