Implemented the new graphics API:

- Removed the internal classes sf::Renderer and sf::Matrix3
- Split sf::Drawable into sf::Drawable and sf::Transformable
- Added sf::Transform
- Added sf::Vertex
- Added sf::VertexArray
- Types of shapes are now handled with their own derived class
- Modified the Pong example
