//! Obsolete clip plane presentation class.
//! Ported on new core of Graphic3d_ClipPlane approach.
//! Please access Graphic3d_ClipPlane via ClipPlane() method
//! to use it for standard clipping workflow.
//! Example of use:
//! @code
//!
//! Handle(V3d_Plane) aPlane (0, 1, 0, -20);
//! Handle(V3d_View) aView;
//! aView->AddClipPlane (aPlane->ClipPlane());
//!
//! aPlane->Display (aView);
//! aPlane->SetPlane (0, 1, 0, -30);
//! aView->RemoveClipPlane (aPlane->ClipPlane());
//!
//! @endcode
//! Use interface of this class to modify plane equation synchronously
//! with clipping equation.
