      Writes text at a specified position relative to the viewport
      boundaries.  Text may be written inside or outside the viewport, but
      is clipped at the subpage boundaries.  The reference point of a
      string lies along a line passing through the string at half the
      height of a capital letter.  The position of the reference point
      along this line is determined by
      <code class="literal"><em class="parameter"><code>just</code></em></code>, and the position of
      the reference point relative to the viewport is set by
      <code class="literal"><em class="parameter"><code>disp</code></em></code> and
      <code class="literal"><em class="parameter"><code>pos</code></em></code>.

	    Specifies the side of the viewport along which the text is to
	    be written. The string should contain one or more of the
	    following characters: <code class="literal">[xyz][ps][v]</code>.
