/// \class sf::RenderWindow
/// \ingroup graphics
///
/// sf::RenderWindow is the main class of the Graphics module.
/// It defines an OS window that can be painted using the other
/// classes of the graphics module.
///
/// sf::RenderWindow is derived from sf::Window, thus it inherits
/// all its features: events, window management, OpenGL rendering,
/// etc. See the documentation of sf::Window for a more complete
/// description of all these features, as well as code examples.
///
/// On top of that, sf::RenderWindow adds more features related to
/// 2D drawing with the graphics module (see its base class
/// sf::RenderTarget for more details).
/// Here is a typical rendering and event loop with a sf::RenderWindow:
///
/// \code
/// // Declare and create a new render-window
/// sf::RenderWindow window(sf::VideoMode(800, 600), "SFML window");
///
/// // Limit the framerate to 60 frames per second (this step is optional)
/// window.setFramerateLimit(60);
///
/// // 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();
///    }
///
///    // Clear the whole window before rendering a new frame
///    window.clear();
///
///    // Draw some graphical entities
///    window.draw(sprite);
///    window.draw(circle);
///    window.draw(text);
///
///    // End the current frame and display its contents on screen
///    window.display();
/// }
/// \endcode
///
/// Like sf::Window, sf::RenderWindow is still able to render direct
/// OpenGL stuff. It is even possible to mix together OpenGL calls
/// and regular SFML drawing commands.
///
/// \code
/// // Create the render window
/// sf::RenderWindow window(sf::VideoMode(800, 600), "SFML OpenGL");
///
/// // Create a sprite and a text to display
/// sf::Sprite sprite;
/// sf::Text text;
/// ...
///
/// // Perform OpenGL initializations
/// glMatrixMode(GL_PROJECTION);
/// ...
///
/// // Start the rendering loop
/// while (window.isOpen())
/// {
///     // Process events
///     ...
///
///     // Draw a background sprite
///     window.pushGLStates();
///     window.draw(sprite);
///     window.popGLStates();
///
///     // Draw a 3D object using OpenGL
///     glBegin(GL_QUADS);
///         glVertex3f(...);
///         ...
///     glEnd();
///
///     // Draw text on top of the 3D object
///     window.pushGLStates();
///     window.draw(text);
///     window.popGLStates();
///
///     // Finally, display the rendered frame on screen
///     window.display();
/// }
/// \endcode
