/// \class sf::Mouse
/// \ingroup window
///
/// sf::Mouse provides an interface to the state of the
/// mouse. It only contains static functions (a single
/// mouse is assumed), so it's not meant to be instanciated.
///
/// This class 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.
///
/// Note that the sf::Mouse::GetPosition function has a special
/// behaviour: it returns the cursor position relative to the
/// window which has the mouse focus (ie. the window on which
/// the cursor is).
///
/// Usage example:
/// \code
/// if (sf::Mouse::IsButtonPressed(sf::Mouse::Left))
/// {
///     // left click...
/// }
/// else if (sf::Mouse::IsButtonPressed(sf::Mouse::Right))
/// {
///     // right click...
/// }
///
/// sf::Vector2i position = sf::Mouse::GetPosition();
/// \endcode
///
/// \see sf::Joystick, sf::Keyboard
