			/** \brief Allows back-button-press events on Windows Phone to be marked as handled
			*
			* Windows Phone devices typically feature a Back button. When pressed,
			* the OS will emit back-button-press events, which apps are expected to
			* handle in an appropriate manner. If apps do not explicitly mark these
			* events as 'Handled', then the OS will invoke its default behavior for
			* unhandled back-button-press events, which on Windows Phone 8 and 8.1 is to
			* terminate the app (and attempt to switch to the previous app, or to the
			* device's home screen).
			*
			* Setting the SDL_HINT_WINRT_HANDLE_BACK_BUTTON hint to "1" will cause SDL
			* to mark back-button-press events as Handled, if and when one is sent to
			* the app.
			*
			* Internally, Windows Phone sends back button events as parameters to
			* special back-button-press callback functions. Apps that need to respond
			* to back-button-press events are expected to register one or more
			* callback functions for such, shortly after being launched (during the
			* app's initialization phase). After the back button is pressed, the OS
			* will invoke these callbacks. If the app's callback(s) do not explicitly
			* mark the event as handled by the time they return, or if the app never
			* registers one of these callback, the OS will consider the event
			* un-handled, and it will apply its default back button behavior (terminate
			* the app).
			*
			* SDL registers its own back-button-press callback with the Windows Phone
			* OS. This callback will emit a pair of SDL key-press events (SDL_KEYDOWN
			* and SDL_KEYUP), each with a scancode of SDL_SCANCODE_AC_BACK, after which
			* it will check the contents of the hint, SDL_HINT_WINRT_HANDLE_BACK_BUTTON.
			* If the hint's value is set to "1", the back button event's Handled
			* property will get set to 'true'. If the hint's value is set to something
			* else, or if it is unset, SDL will leave the event's Handled property
			* alone. (By default, the OS sets this property to 'false', to note.)
			*
			* SDL apps can either set SDL_HINT_WINRT_HANDLE_BACK_BUTTON well before a
			* back button is pressed, or can set it in direct-response to a back button
			* being pressed.
			*
			* In order to get notified when a back button is pressed, SDL apps should
			* register a callback function with SDL_AddEventWatch(), and have it listen
