/// \class sf::Drawable
/// \ingroup graphics
///
/// sf::Drawable is a very simple base class that allows objects
/// of derived classes to be drawn to a sf::RenderTarget.
///
/// All you have to do in your derived class is to override the
/// draw virtual function.
///
/// Note that inheriting from sf::Drawable is not mandatory,
/// but it allows this nice syntax "window.draw(object)" rather
/// than "object.draw(window)", which is more consistent with other
/// SFML classes.
///
/// Example:
/// \code
/// class MyDrawable : public sf::Drawable
/// {
/// public:
///
/// ...
///
/// private:
///
/// virtual void draw(sf::RenderTarget& target, sf::RenderStates states) const
/// {
/// // You can draw other high-level objects
/// target.draw(m_sprite, states);
///
/// // ... or use the low-level API
/// states.texture = &m_texture;
/// target.draw(m_vertices, states);
///
/// // ... or draw with OpenGL directly
/// glBegin(GL_QUADS);
/// ...
/// glEnd();
/// }
///
/// sf::Sprite m_sprite;
/// sf::Texture m_texture;
/// sf::VertexArray m_vertices;
/// };
/// \endcode
