<h1>webGL test</h1>
Checks if the addon also supports webGL.
<h2>Expected result</h2>
<ul>
<li>both webGL versions should be supported (unless you disabled it in the browser settings) - reload if one is showing "not supported"</li>
<li>upon page reload the hashes change</li>
<li>upon page reload some of the parameters change</li>
<li>the "vendor" und "renderer" (also unmasked) parameters reflect the values you chose for them</li>
</ul>
<h3>Support</h3>
<div id="output"></div>
<h3>Parameters</h3>

<script src="webGL-Test.js"></script>
