Graphic3d_Camera::TransformMatrices redundant NCollection_Handle usage has been replaced with validity flags. Graphic3d_TransModeFlags now defined as enumeration, not integer bit flags. Graphic3d_TMF_PanPers and Graphic3d_TMF_FullPers have been removed. Graphic3d_TMF_ZoomRotatePers has been introduced. Graphic3d_TransformPers is now inherits Standard_Transient. Graphic3d_TransformPers now defines dedicated constructors for 3D persistence (zoom / rotate) and 2D persistence (2d / trihedron). 2D persistence now supports dedicated values for X and Y offsets. The corner is now specified by enumeration Aspect_TypeOfTriedronPosition instead of indirect interpretation of anchor point values. Fixed handling of Graphic3d_TMF_ZoomRotatePers (combination of Graphic3d_TMF_RotatePers + Graphic3d_TMF_ZoomPers). PrsMgr_PresentableObject, Graphic3d_CStructure now hold Handle(Graphic3d_TransformPers) instead of a value. Method ::SetTransformPersistence(), ::TransformPersistence() now works with Handle(Graphic3d_TransformPers). Old methods have been marked deprecated.
