Window: fullScreen property

The fullScreen property of the Window interface indicates whether the window is displayed in fullscreen mode or not.

Notes

• Switching between regular window and full screen will fire the "resize" event on the corresponding window.

  // it's fullscreen!
} else {
  // not fullscreen!
}
