 Review comment:
   @mike-jumper If we move the tests for `requestFullScreen()`  and 
`exitFullscreen()` into the body, then we could detect if the current browser 
has support for fullscreen before adding the function to the menu.
   
   Should we still display the fullscreen menu or is it better to hide it ?
