		A helper script for getting into a kind of 'fullscreen mode' on iOS 
		from inside an iframe.
		
		iOS itself doesn't support the HTML5 Fullscreen API and so there is no
		way to make the pano window larger than the iframe area itself.
		This script therefore adds a fake-fullscreen-mode support and redirects
		the browser window directly to the inner iframe page to make the iframe
		itself beeing the full browser page.
		
		Note: this scripts only enables the fullscreen contextmenu item, 
		custom xml elements that are depending on the 'device.fullscreensupport'
		state would need to get enabled manually. That's because the xml parsing
		and the xml element 'devices filtering' is happening before this script is
		running. For 'manual enabling' e.g. remove the 'fullscreensupport' 
		devices check from the related elements in the xml files.
