<h1>TextMetrics test</h1>
<h2>Expected result</h2>
<ul>
<ol>
<li>the hashes are different to the hashes when CanvasBlocker is disabled</li>
<li>the number of differences stays the same when CanvasBlocker is disabled</li>
<li>if "refresh" is clicked nothing must change</li>
<li>upon page reload the hashes change (depending on CanvasBlocker settings - e.g. not in the stealth preset)</li>
</ul>
<li>Firefox 68 does only offer integer precision in TextMetrics and therefore less fingerprinting potential. CanvasBlocker only changes values if they are no integer and therefore point 1 and 4 are not true in Firefox 68.</li>
</ol>
