title: TCPDF Multicell valign not working
body: <p>I try to generate a PDF with TCPDF 5.9.141, but valign doesn't seem to work. It's in a CakePHP 2.0 function, but I don't think it matters. 
  According to the documentation everything is valid in my code:</p>
  
  <blockquote>
    <ul>
    <li>Vertical alignment of text (requires $maxh = $h > 0)</li>
    <li>This feature works only when $ishtml=false </li>
    <li>and the cell must fit in a single page. </li>
    </ul>
  </blockquote>
  
  <pre><code>$pdf = new TCPDF('P', 'mm', 'A4', true, 'UTF-8', false);
  $pdf-&gt;setPrintHeader(false);
  $pdf-&gt;setPrintFooter(false);
  
  $pdf-&gt;SetFont('helvetica', '', 7);
  $pdf-&gt;AddPage();
  $pdf-&gt;MultiCell($w=20, $h=15, $txt='teszt', $border='1', $align='C', $fill=false, $x=1, $y=1, $reseth=true, $strech=0, $ishtml=false, $autopadding=true, $maxh=15,  $valign='M', $fitcell=true);
  $pdf-&gt;Output('cimkelista.pdf', 'I');
  </code></pre>
  
  <p>Does anyone have any suggesions?<br>
  Thanks in advance!</p>
