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superseded by 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 < code < 32, then a useful (but small
subset) of Hershey symbols is plotted. If 32 <= code <= 127 the
corresponding printable ASCII character is plotted.
