//! domain of the surface being trimmed.
//! The trimmed surface is defined by:
//! - the basis surface, and
//! - the values (umin, umax) and (vmin, vmax)
//! which limit it in the u and v parametric directions.
//! The trimmed surface is built from a copy of the basis
//! surface. Therefore, when the basis surface is
//! modified the trimmed surface is not changed.
//! Consequently, the trimmed surface does not
//! necessarily have the same orientation as the basis surface.
//! Warning:  The  case of surface   being trimmed is  periodic and
//! parametrics values are outside the domain is possible.
//! But, domain of the  trimmed surface can be translated
//! by (n X) the period.
