/// \class sf::Vertex
/// \ingroup graphics
///
/// A vertex is an improved point. It has a position and other
/// extra attributes that will be used for drawing: in SFML,
/// vertices also have a color and a pair of texture coordinates.
///
/// The vertex is the building block of drawing. Everything which
/// is visible on screen is made of vertices. They are grouped
/// as 2D primitives (triangles, quads, ...), and these primitives
/// are grouped to create even more complex 2D entities such as
/// sprites, texts, etc.
///
/// If you use the graphical entities of SFML (sprite, text, shape)
/// you won't have to deal with vertices directly. But if you want
/// to define your own 2D entities, such as tiled maps or particle
/// systems, using vertices will allow you to get maximum performances.
///
/// Example:
/// \code
/// // define a 100x100 square, red, with a 10x10 texture mapped on it
/// sf::Vertex vertices[] =
/// {
///     sf::Vertex(sf::Vector2f(  0,   0), sf::Color::Red, sf::Vector2f( 0,  0)),
///     sf::Vertex(sf::Vector2f(  0, 100), sf::Color::Red, sf::Vector2f( 0, 10)),
///     sf::Vertex(sf::Vector2f(100, 100), sf::Color::Red, sf::Vector2f(10, 10)),
///     sf::Vertex(sf::Vector2f(100,   0), sf::Color::Red, sf::Vector2f(10,  0))
/// };
///
/// // draw it
/// window.draw(vertices, 4, sf::Quads);
/// \endcode
///
/// Note: although texture coordinates are supposed to be an integer
/// amount of pixels, their type is float because of some buggy graphics
/// drivers that are not able to process integer coordinates correctly.
///
/// \see sf::VertexArray
