title: tcpdf: add some space after writeHTML
body: <p>I write some lines in TCPDF with</p>
  
  <pre><code>$this-&gt;writeHTML('&lt;p&gt;blabla&lt;/p&gt;', true, 0, true, true);
  $this-&gt;writeHTML('&lt;p&gt;blabla&lt;/p&gt;', true, 0, true, true);
  </code></pre>
  
  <p>What can I do to add some space between the two blocks? I tried</p>
  
  <pre><code>$this-&gt;writeHTML('&lt;p style="margin-bottom:10px"&gt;blabla&lt;/p&gt;', true, 0, true, true);
  $this-&gt;writeHTML('&lt;p&gt;blabla&lt;/p&gt;', true, 0, true, true);
  </code></pre>
  
  <p>but as I read later TCPDF can not translate margin-bottom. I could use Cells instead but I think then I would have to calculate their heights and so on to put them on the correct position, right?</p>
  
  <p>Any suggestions?</p>
