Avoid API fullscreen requests when already in native fullscreen mode #57

Is there any cross-browser safe way to determine wether we are in ''native'' fullscreen mode (ie: user has entered browser fullscreen mode (F11, CMD + SHIFT + F)) ?

If so, it would be nice to prevent screenfull.request() to actually perform an unnecessary API call and displaying the consequent notice to inform we have (re) entered fullscreen mode.

Not that I'm aware of. At least in Chrome the "native" fullscreen is also different from the programmatic fullscreen, where the former shows the tabs. So you would still want to enter the programmatic fullscreen even if the user is already in the former one.
