//! system, and provides a coordinate system for
//! drawing curves and shapes in a plane.
//! There are 3 selection modes:
//! -   mode 0   selection of the whole plane "trihedron"
//! -   mode 1   selection of the origin of the plane "trihedron"
//! -   mode 2   selection of the axes.
//! Warning
//! For the presentation of planes and trihedra, the
//! millimetre is default unit of length, and 100 the default
//! value for the representation of the axes. If you modify
//! these dimensions, you must temporarily recover the
//! Drawer object. From inside it, take the Aspects in
//! which   the values for length are stocked, for example,
//! PlaneAspect for planes and LineAspect for
//! trihedra. Change these values and recalculate the presentation.
