/// \class sf::Transformable
/// \ingroup graphics
///
/// This class is provided for convenience, on top of sf::Transform.
///
/// sf::Transform, as a low-level class, offers a great level of
/// flexibility but it is not always convenient to manage. Indeed,
/// one can easily combine any kind of operation, such as a translation
/// followed by a rotation followed by a scaling, but once the result
/// transform is built, there's no way to go backward and, let's say,
/// change only the rotation without modifying the translation and scaling.
/// The entire transform must be recomputed, which means that you
/// need to retrieve the initial translation and scale factors as
/// well, and combine them the same way you did before updating the
/// rotation. This is a tedious operation, and it requires to store
/// all the individual components of the final transform.
///
/// That's exactly what sf::Transformable was written for: it hides
/// these variables and the composed transform behind an easy to use
/// interface. You can set or get any of the individual components
/// without worrying about the others. It also provides the composed
/// transform (as a sf::Transform), and keeps it up-to-date.
///
/// In addition to the position, rotation and scale, sf::Transformable
/// provides an "origin" component, which represents the local origin
/// of the three other components. Let's take an example with a 10x10
/// pixels sprite. By default, the sprite is positioned/rotated/scaled
/// relatively to its top-left corner, because it is the local point
/// (0, 0). But if we change the origin to be (5, 5), the sprite will
/// be positioned/rotated/scaled around its center instead. And if
/// we set the origin to (10, 10), it will be transformed around its
/// bottom-right corner.
///
/// To keep the sf::Transformable class simple, there's only one
/// origin for all the components. You cannot position the sprite
/// relatively to its top-left corner while rotating it around its
/// center, for example. To do such things, use sf::Transform directly.
///
/// sf::Transformable can be used as a base class. It is often
/// combined with sf::Drawable -- that's what SFML's sprites,
/// texts and shapes do.
/// \code
/// class MyEntity : public sf::Transformable, public sf::Drawable
/// {
/// virtual void draw(sf::RenderTarget& target, sf::RenderStates states) const
/// {
/// states.transform *= getTransform();
/// target.draw(..., states);
/// }
/// };
///
/// MyEntity entity;
/// entity.setPosition(10, 20);
/// entity.setRotation(45);
/// window.draw(entity);
/// \endcode
///
/// It can also be used as a member, if you don't want to use
/// its API directly (because you don't need all its functions,
/// or you have different naming conventions for example).
/// \code
/// class MyEntity
/// {
/// public:
/// void SetPosition(const MyVector& v)
/// {
/// myTransform.setPosition(v.x(), v.y());
/// }
///
/// void Draw(sf::RenderTarget& target) const
/// {
/// target.draw(..., myTransform.getTransform());
/// }
///
/// private:
/// sf::Transformable myTransform;
/// };
/// \endcode
///
/// A note on coordinates and undistorted rendering: \n
/// By default, SFML (or more exactly, OpenGL) may interpolate drawable objects
/// such as sprites or texts when rendering. While this allows transitions
/// like slow movements or rotations to appear smoothly, it can lead to
/// unwanted results in some cases, for example blurred or distorted objects.
/// In order to render a sf::Drawable object pixel-perfectly, make sure
/// the involved coordinates allow a 1:1 mapping of pixels in the window
/// to texels (pixels in the texture). More specifically, this means:
/// * The object's position, origin and scale have no fractional part
/// * The object's and the view's rotation are a multiple of 90 degrees
/// * The view's center and size have no fractional part
///
/// \see sf::Transform
