//! * Create an ellipse from its center, and two points:

//! The sense of parametrization is given by S1, S2,

//! Depending on the constructor, the implicit orientation of the ellipse is:

//! - the sense defined by points Center, S1 and S2,

//! - gce_InvertRadius if MajorRadius is less than MinorRadius,
//! - gce_NegativeRadius if MajorRadius or
//! MinorRadius is less than 0.0,
