title: Application go fullscreen at startup
body: <p>Since MacOSX Lion, Cocoa supports a new fullscreen feature.
  I implement it in my application window thanks to the following instruction from my application delegate:</p>
  
  <pre><code>[_window setCollectionBehavior:NSWindowCollectionBehaviorFullScreenPrimary];
  </code></pre>
  
  <p>Is it possible to go to this presentation at startup?</p>
  
  <p>Thanks for help!</p>
  
  <p>Edit: I still want the fullscreen menu bar feature (which doesn't work with <em>enterFullscreenMode:withOptions:</em></p>
