/// `sf::Mouse` provides an interface to the state of the
/// mouse. A single mouse is assumed.
///
/// This namespace allows users to query the mouse state at any
/// time and directly, without having to deal with a window and
/// its events. Compared to the `MouseMoved`, `MouseButtonPressed`
/// and `MouseButtonReleased` events, `sf::Mouse` can retrieve the
/// state of the cursor and the buttons at any time
/// (you don't need to store and update a boolean on your side
/// in order to know if a button is pressed or released), and you
/// always get the real state of the mouse, even if it is
/// moved, pressed or released when your window is out of focus
/// and no event is triggered.
///
/// The `setPosition` and `getPosition` functions can be used to change
/// or retrieve the current position of the mouse pointer. There are
/// two versions: one that operates in global coordinates (relative
/// to the desktop) and one that operates in window coordinates
/// (relative to a specific window).
///
/// Usage example:
/// \code
/// if (sf::Mouse::isButtonPressed(sf::Mouse::Button::Left))
/// {
///     // left click...
/// }
///
/// // get global mouse position
/// sf::Vector2i position = sf::Mouse::getPosition();
///
/// // set mouse position relative to a window
/// sf::Mouse::setPosition(sf::Vector2i(100, 200), window);
/// \endcode
///
/// \see `sf::Joystick`, `sf::Keyboard`, `sf::Touch`
