 //! Geometric transformation on a shape.
 //! The transformation to be applied is defined as a
 //! gp_Trsf transformation, i.e. a transformation which does
 //! not modify the underlying geometry of shapes.
 //! The transformation is applied to:
 //! -   all curves which support edges of a shape, and
 //! -   all surfaces which support its faces.
 //! A Transform object provides a framework for:
 //! -   defining the geometric transformation to be applied,
 //! -   implementing the transformation algorithm, and
 //! -   consulting the results.
