title: Tcpdf writeHTMLCell without overlapping boxes
body: <p>I am creating a pdf with text images (1 image per page), and I need to add some boxes to the left and/or right of the image explaining some expressions from the image (using specific Y coordinates)</p>
  <p>the problem is that sometimes the expressions are on the same row, and if I use the same Y coordinate when using writeHTMLCell or any other method that uses the Y as parameter, they will overlap</p>
  <p>My question is .. is there a way of adding multiple boxes, without them overlapping?</p>
  <pre><code>$pdf-&gt;writeHTMLCell(50, 0, '', '10', 'First box', 1, 1, 0, true, 'J');
  $pdf-&gt;writeHTMLCell(50, 0, '', '20', 'Second box', 1, 1, 0, true, 'J');
  $pdf-&gt;writeHTMLCell(50, 0, '', '21', 'Third box', 1, 1, 0, true, 'J');
  $pdf-&gt;writeHTMLCell(50, 0, '', '35', 'Fourth box box', 1, 1, 0, true, 'J');
  $pdf-&gt;writeHTMLCell(50, 0, '', '38', 'Fifth box box', 1, 1, 0, true, 'J');
  </code></pre>
