The class Transformation allows to create Translation,

//! obtained by combination of the previous elementary
//! transformations.
//! The Transformation class can also be used to
//! construct complex transformations by combining
//! these elementary transformations.
//! However, these transformations can never change
//! the type of an object. For example, the projection
//! transformation can change a circle into an ellipse,
//! and therefore change the real type of the object.
//! Such a transformation is forbidden in this
//! environment and cannot be a Geom2d_Transformation.
//! The transformation can be represented as follow :
//!
//! V1 V2 T
//! | a11 a12 a14 | | x | | x'|
//! | a21 a22 a24 | | y | | y'|
//! | 0 0 1 | | 1 | | 1 |
