title: In Opera, is it possible to set a flag to enable the Fullscreen API to trigger without an event?
body: <p>In Firefox, it is possible to set a flag in the <code>about:config</code> page to enable calls to <code>element.mozRequestFullScreen();</code> to work even if the user did not initiate a fullscreen event. The flag in question: <code>full-screen-api.approval-required;false</code> Of course, this only applies to browsers I control (which is true in my case). I want to develop a kiosk application, and I want the app to enable full screen mode, and I have selected Opera to be the browser which is used to serve my app.</p>
  
  <p>Is there a similar flag or option that can achieve the same in Opera? Alternately, is it possible to start Opera in full screen mode? Ever since they have switched their engine to webkit, the documentation is out of date and many of the start flags do not work.</p>
  
  <p>Anyone has any idea?</p>
