+///
+/// It inherits sf::Drawable, but unlike other drawables it
+/// is not transformable.
+///
+/// Example:
+/// \code
+/// sf::VertexArray lines(sf::LineStrip, 4);
+/// lines[0].position = sf::Vector2f(10, 0);
+/// lines[1].position = sf::Vector2f(20, 0);
+/// lines[2].position = sf::Vector2f(30, 5);
+/// lines[3].position = sf::Vector2f(40, 2);
+///
+/// window.draw(lines);
+/// \endcode
