- *  \mainpage Simple DirectMedia Layer (SDL)
- *
- *  http://www.libsdl.org/
- *
- *  \section intro_sec Introduction
- *
- *  Simple DirectMedia Layer is a cross-platform development library designed
- *  to provide low level access to audio, keyboard, mouse, joystick, and
- *  graphics hardware via OpenGL and Direct3D. It is used by video playback
- *  software, emulators, and popular games including Valve's award winning
- *  catalog and many Humble Bundle games.
- *
- *  SDL officially supports Windows, Mac OS X, Linux, iOS, and Android.
- *  Support for other platforms may be found in the source code.
- *
- *  SDL is written in C, works natively with C++, and there are bindings 
- *  available for several other languages, including C# and Python.
- *
- *  This library is distributed under the zlib license, which can be found
- *  in the file "COPYING.txt".
- *
- *  The best way to learn how to use SDL is to check out the header files in
- *  the "include" subdirectory and the programs in the "test" subdirectory.
- *  The header files and test programs are well commented and always up to date.
- *  More documentation and FAQs are available online at:
- *      http://wiki.libsdl.org/
- *
- *  If you need help with the library, or just want to discuss SDL related
- *  issues, you can join the developers mailing list:
- *      http://www.libsdl.org/mailing-list.php
- *
- *  Enjoy!
- *      Sam Lantinga                (slouken@libsdl.org)

+/** \brief Allows back-button-press events on Windows Phone to be marked as handled
  *
- *  TODO, WinRT: document SDL_HINT_WINRT_HANDLE_BACK_BUTTON need and use
+ *  Windows Phone devices typically feature a Back button.  When pressed,
- *  For now, more details on why this is needed can be found at the
+ *  the OS will emit back-button-press events, which apps are expected to
- *  beginning of the following web page:
+ *  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

+/**
+ *  \brief Capture the mouse, to track input outside an SDL window.
+ *
+ *  \param enabled Whether or not to enable capturing
+ *
+ *  Capturing enables your app to obtain mouse events globally, instead of
+ *  just within your window. Not all video targets support this function.
+ *  When capturing is enabled, the current window will get all mouse events,
+ *  but unlike relative mode, no change is made to the cursor and it is
+ *  not restrained to your window.
+ *
+ *  This function may also deny mouse input to other windows--both those in
+ *  your application and others on the system--so you should use this
+ *  function sparingly, and in small bursts. For example, you might want to
+ *  track the mouse while the user is dragging something, until the user
+ *  releases a mouse button. It is not recommended that you capture the mouse
+ *  for long periods of time, such as the entire time your app is running.
+ *
+ *  While captured, mouse events still report coordinates relative to the
+ *  current (foreground) window, but those coordinates may be outside the
+ *  bounds of the window (including negative values). Capturing is only
+ *  allowed for the foreground window. If the window loses focus while
+ *  capturing, the capture will be disabled automatically.
+ *
+ *  While capturing is enabled, the current window will have the
+ *  SDL_WINDOW_MOUSE_CAPTURE flag set.
+ *
+ *  \return 0 on success, or -1 if not supported.

+ *    khronos_uint8_t             unsigned 8  bit

+ *    khronos_intptr_t            signed   same number of bits as a pointer
+ *    khronos_uintptr_t           unsigned same number of bits as a pointer
+ *    khronos_ssize_t             signed   size
+ *    khronos_usize_t             unsigned size
+ *    khronos_float_t             signed   32 bit floating point
+ *    khronos_time_ns_t           unsigned 64 bit time in nanoseconds

+ *      an enum. Client APIs which use an integer or other type for
+ *      booleans cannot use this as the base type for their boolean.

+ *  \brief Provide a callback that decides if a window region has special properties.

+ *  makes sense to drag them from somewhere else inside the window itself; for
+ *  example, one might have a borderless window that wants to be draggable
+ *  from any part, or simulate its own title bar, etc.
+ *
+ *  This function lets the app provide a callback that designates pieces of
+ *  a given window as special. This callback is run during event processing
+ *  if we need to tell the OS to treat a region of the window specially; the
+ *  use of this callback is known as "hit testing."
+ *
+ *  Mouse input may not be delivered to your application if it is within
+ *  a special area; the OS will often apply that input to moving the window or
+ *  resizing the window and not deliver it to the application.
+ *
+ *  Specifying NULL for a callback disables hit-testing. Hit-testing is
+ *  disabled by default.
+ *
+ *  Platforms that don't support this functionality will return -1
+ *  unconditionally, even if you're attempting to disable hit-testing.
+ *
+ *  Your callback may fire at any time, and its firing does not indicate any
+ *  specific behavior (for example, on Windows, this certainly might fire
+ *  when the OS is deciding whether to drag your window, but it fires for lots
+ *  of other reasons, too, some unrelated to anything you probably care about
+ *  _and when the mouse isn't actually at the location it is testing_).
+ *  Since this can fire at any time, you should try to keep your callback
+ *  efficient, devoid of allocations, etc.
+ *
+ *  \param window The window to set hit-testing on.
+ *  \param callback The callback to call when doing a hit-test.
+ *  \param callback_data An app-defined void pointer passed to the callback.
