title: transparent background node webkit window
body: <p>I can do almost everything else with nwjs so I find my failure to make this work very frustrating.</p>
  
  <p>I have made the simplest of html file with <code>&lt;body style="background-color:rgba(0,0,0,0);"&gt;&lt;/body&gt;</code> and <code>"transparent":true,</code> in the window section of package.json, but the window background remains white.</p>
  
  <p>(I have a new Dell tablet PC running windows 8.1.) </p>
  
  <p>Something I've missed?</p>
