Graphic3d_SequenceOfHClipPlane now inherits Standard_Transient. PrsMgr_PresentableObject, Graphic3d_Structure, Graphic3d_CStructure, V3d_View, OpenGl_View now manages the plane list by Handle. The getters ::GetClipPlanes() has been removed, setters taking non-handle ::SetClipPlanes() has been marked deprecated. OpenGl_Structure::Render() and SelectMgr_ViewerSelector::checkOverlap() now disable global (view) clipping planes for objects with flags Graphic3d_TMF_TriedronPers and Graphic3d_TMF_2d or with new flag Graphic3d_SequenceOfHClipPlane::ToOverrideGlobal(). OpenGl_Clipping now implements interface for managing clipping planes without copying the sequences. The filtering of duplicates is no more performed by OpenGl_Clipping - application is responsible to not do this. OpenGl_Clipping tries avoiding unnecessary allocations for managing list of active planes. MFC sample has been updated to use V3d_View::ClipPlanes() method.
