/// sf::WindowBase serves as the base class for all Windows.
///
/// A sf::WindowBase can create its own new window, or be embedded into
/// an already existing control using the create(handle) function.
///
/// The sf::WindowBase class provides a simple interface for manipulating
/// the window: move, resize, show/hide, control mouse cursor, etc.
/// It also provides event handling through its pollEvent() and waitEvent()
/// functions.
///
/// Usage example:
/// \code
/// // Declare and create a new window
/// sf::WindowBase window(sf::VideoMode(800, 600), "SFML window");
///
/// // The main loop - ends as soon as the window is closed
/// while (window.isOpen())
/// {
/// // Event processing
/// sf::Event event;
/// while (window.pollEvent(event))
/// {
/// // Request for closing the window
/// if (event.type == sf::Event::Closed)
/// window.close();
/// }
///
/// // Do things with the window here...
/// }
/// \endcode
