title: adding font to mPDF
body: <p>I'm getting the following error when I try and generate a PDF using the mPDF class:</p>
  
  <pre><code>TTF file "C:/wamp/www/inc/mpdf/ttfonts/verdana.ttf": invalid checksum 20f65173c11 table: DSIG (expected 65173c11)
  </code></pre>
  
  <p>I've uploaded the font files to my <code>ttfonts</code> directory and defined the font in <code>config_fonts.php</code> like this:</p>
  
  <pre><code>"verdana" =&gt; array(
      'R' =&gt; "verdana.ttf",
      'B' =&gt; "verdanab.ttf",
      'I' =&gt; "verdanai.ttf",
      'BI' =&gt; "verdanaz.ttf",
      ),
  </code></pre>
  
  <p>I only see the error when I turn on font error reporting in the config settings. When I turn error reporting off, the PDF is generated, but the font being used is not Verdana. </p>
  
  <p>Any idea on what I'm doing wrong?</p>
