       plpoin - Plot a glyph at the specified points


       plpoin(n, x, y, code)


       Plot  a  glyph  at  the  specified  points.   (This  function  is  largely  superseded  by
       plstring(3plplot) which gives access to many[!] more glyphs.) code=-1 means  try  to  just
       draw  a point.  Right now it's just a move and a draw at the same place.  Not ideal, since
       a sufficiently intelligent output device may optimize it away, or there may be faster ways
       of  doing  it.  This is OK for now, though, and offers a 4X speedup over drawing a Hershey
       font "point" (which is actually diamond shaped and therefore takes 4 strokes to draw).  If
       0  <  code < 32, then a useful (but small subset) of Hershey symbols is plotted.  If 32 <=
       code <= 127 the corresponding printable ASCII character is plotted.

       Redacted form: plpoin(x, y, code)

       This function is used in examples 1,6,14,21,29.


       n (PLINT, input)
              Number of points in the x and y arrays.

       x (PLFLT *, input)
              Pointer to an array with X coordinates of points.

       y (PLFLT *, input)
              Pointer to an array with Y coordinates of points.

       code (PLINT, input)
              Hershey symbol code (in "ascii-indexed" form with -1 <= code <= 127)  corresponding
              to a glyph to be plotted at each of the n points.
