What does fixScale(document) do?
<p>I created a new GitHub page using their <a href="https://help.github.com/articles/creating-pages-with-the-automatic-generator" rel="nofollow">automatic generator</a> and, in the generated page, found this line from the <a href="https://github.com/mattgraham/Midnight/blob/3e9ff80a/index.html#L136" rel="nofollow">GitHub template</a>:</p>

<pre><code>&lt;!--[if !IE]&gt;&lt;script&gt;fixScale(document);&lt;/script&gt;&lt;!--&lt;![endif]--&gt;
</code></pre>

<p>This being from the good boys and girls at GitHub, I wondered if this is something I might want to adapt from my own HTML. But none of the javascript referenced in that file define such a function and this doesn't seem to be a native (window) function.</p>

<p>So, what does this function do and would I want to include it in my own HTML?</p>
