title: Support for target-densitydpi is removed from WebKit
body: <p>According to this <a href="https://bugs.webkit.org/show_bug.cgi?id=88047">https://bugs.webkit.org/show_bug.cgi?id=88047</a> WebKit dropped the support for target-densitydpi from viewport params. Unfortunately, the bug description states neither the motivation for the change, nor the workaround. </p>
  
  <p>Certain web-pages that wanted to prevent scaling on mobile devices had the following declaration of the viewport:</p>
  
  <pre><code>&lt;meta name="viewport" content="width=device-width, 
  initial-scale=1.0, maximum-scale=1.0, 
  user-scalable=no, target-densitydpi=device-dpi"/&gt;
  </code></pre>
  
  <p>Now this code outputs an error in Chrome (tested with 21.0.1180.49 beta-m). Please advice what is the supposed way to make a web-page without the error messages and retain the same behavior as before with target-densitydpi=device-dpi"</p>
