1// This THREEx helper makes it easy to handle the fullscreen API
2// * it hides the prefix for each browser
3// * it hides the little discrepencies of the various vendor API
4// * at the time of this writing (nov 2011) it is available in 
5//   [firefox nightly](http://blog.pearce.org.nz/2011/11/firefoxs-html-full-screen-api-enabled.html),
6//   [webkit nightly](http://peter.sh/2011/01/javascript-full-screen-api-navigation-timing-and-repeating-css-gradients/) and
7//   [chrome stable](http://updates.html5rocks.com/2011/10/Let-Your-Content-Do-the-Talking-Fullscreen-API).
