+
+/** \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
+ * for SDL_KEYDOWN events that have a scancode of SDL_SCANCODE_AC_BACK.
+ * (Alternatively, SDL_KEYUP events can be listened-for. Listening for
+ * either event type is suitable.) Any value of SDL_HINT_WINRT_HANDLE_BACK_BUTTON
+ * set by such a callback, will be applied to the OS' current
+ * back-button-press event.
+ *
+ * More details on back button behavior in Windows Phone apps can be found
+ * at the following page, on Microsoft's developer site:
* http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj247550(v=vs.105).aspx
