/// \class sf::VideoMode
/// \ingroup window
///
/// A video mode is defined by a width and a height (in pixels)
/// and a depth (in bits per pixel). Video modes are used to
/// setup windows (sf::Window) at creation time.
///
/// The main usage of video modes is for fullscreen mode:
/// indeed you must use one of the valid video modes
/// allowed by the OS (which are defined by what the monitor
/// and the graphics card support), otherwise your window
/// creation will just fail.
///
/// sf::VideoMode provides a static function for retrieving
/// the list of all the video modes supported by the system:
/// getFullscreenModes().
///
/// A custom video mode can also be checked directly for
/// fullscreen compatibility with its isValid() function.
///
/// Additionally, sf::VideoMode provides a static function
/// to get the mode currently used by the desktop: getDesktopMode().
/// This allows to build windows with the same size or pixel
/// depth as the current resolution.
///
/// Usage example:
/// \code
/// // Display the list of all the video modes available for fullscreen
/// std::vector<sf::VideoMode> modes = sf::VideoMode::getFullscreenModes();
/// for (std::size_t i = 0; i < modes.size(); ++i)
/// {
/// sf::VideoMode mode = modes[i];
/// std::cout << "Mode #" << i << ": "
/// << mode.width << "x" << mode.height << " - "
/// << mode.bitsPerPixel << " bpp" << std::endl;
/// }
///
/// // Create a window with the same pixel depth as the desktop
/// sf::VideoMode desktop = sf::VideoMode::getDesktopMode();
/// window.create(sf::VideoMode(1024, 768, desktop.bitsPerPixel), "SFML window");
/// \endcode
