/**
* \brief Get the current state of the mouse, in relation to the desktop

* This works just like SDL_GetMouseState(), but the coordinates will be
* reported relative to the top-left of the desktop. This can be useful if
* you need to track the mouse outside of a specific window and
* SDL_CaptureMouse() doesn't fit your needs. For example, it could be
* useful if you need to track the mouse while dragging a window, where
* coordinates relative to a window might not be in sync at all times.
*
* \note SDL_GetMouseState() returns the mouse position as SDL understands
* it from the last pump of the event queue. This function, however,
* queries the OS for the current mouse position, and as such, might
* be a slightly less efficient function. Unless you know what you're
* doing and have a good reason to use this function, you probably want
* SDL_GetMouseState() instead.
*
* \param x Returns the current X coord, relative to the desktop. Can be NULL.
* \param y Returns the current Y coord, relative to the desktop. Can be NULL.
* \return The current button state as a bitmask, which can be tested using the SDL_BUTTON(X) macros.

/**
* \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.
