//! The class Transformation allows to create Translation, <br>
//! Rotation, Symmetry, Scaling and complex transformations <br>
//! obtained by combination of the previous elementary <br>
//! transformations. <br>
//! The Transformation class can also be used to <br>
//! construct complex transformations by combining <br>
//! these elementary transformations. <br>
//! However, these transformations can never change <br>
//! the type of an object. For example, the projection <br>
//! transformation can change a circle into an ellipse, <br>
//! and therefore change the real type of the object. <br>
//! Such a transformation is forbidden in this <br>

//! The transformation can be represented as follow : <br>
//! <br>

//! | a21 a22 a24 | | y | | y'| <br>
