      Plot a glyph at the specified 3D points.  (This function is largely
      superseded by <a class="link" href="plstring3.html" title="plstring3: Plot a glyph at the specified 3D points"><code class="function">plstring3</code></a> which gives access to many[!] more glyphs.)
      Set up the call to this function similar to what is done for <a class="link" href="plline3.html" title="plline3: Draw a line in 3 space"><code class="function">plline3</code></a>.
      <code class="literal"><em class="parameter"><code>code</code></em>=-1</code> 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 &lt; code &lt; 32, then a useful (but small
      subset) of Hershey symbols is plotted.  If 32 &lt;= code &lt;= 127 the
      corresponding printable ASCII character is plotted.
