0025571: Avoid base Classes without virtual Destructors
Destructors of collection classes from NCollection and math_Function are made virtual to allow safe destruction by pointer to base class.
Destructors of classes HatchGen_IntersectionPoint, IntCurveSurface_Intersection, Intf_Interference, IntRes2d_Intersection are made protected to avoid possibility of destructing by pointer to corresponding base class.
0026680: Visualization - Changed behavior of mesh visualization and selection in OMF sample
- handling of global selection mode was added to MeshVS_Mesh;
- corrected unhighlight of interactives with auto-highlight disabled;
- test case for issue 0026680.
0022972: Eliminate macro definitions that has compiler-provided analogs (WNT and so on)
1) Macro definition WNT replaced by _WIN32 and _MSC_VER for platform and compiler detection accordingly.
2) Macro definition LIN replaced by __linux__ macro.
3) Macro definition DEB replaced by OCCT_DEBUG macro.
0026676: Visualization, Ray Tracing - correct rendering if stereo pair
- Fixed interpolation of ray direction vector for asymmetric frustum (stereo left/right eye). Unnecessary normalization of direction vector affecting the frustum's geometry was removed.
- Fixed usage of projection type argument passed when rendering immediate graphics with stereo projection.
0024776: Visualization - inherit OpenGl_View from Graphic3d_CView
Expose interface of OpenGl_View (OpenGL graphics rendering methods) to client code
and collecting all high-level API methods of application views in V3d_View class.
1) Exposing interface of OpenGl_View:
The OpenGl_View inherits from new class Graphic3d_CView.
Graphic3d_CView is an interface class that declares abstract methods for managing displayed structures,
display properties and a base layer code that implements computation
and management of HLR (or more broadly speaking view-depended) structures.
In new implementation it takes place of eliminated Visual3d_View.
As before the instance of Graphic3d_CView is still completely managed by V3d_View classes.
It can be accessed through V3d_View interface but normally this should not be required as all its methods are completely wrapped.
In more details, a concrete specialization of Graphic3d_CView is created and returned by graphical driver on request.
Right after creation the views is directly used for setting rendering properties and adding graphical structures to be displayed.
The rendering of graphics is possible after mapping a window and activating the view.
The direct setting of properties makes obsolete usage of intermediate structures with display parameter
like Visual3d_ContextView and etc (the whole package of Visual3d become redundant).
2) Collecting all high-level API methods of application views in V3d package:
The patch includes elimination of Visual3d layer.
All of its methods that could be previously used by application are now exposed and should be accessed on the level of V3d entities.
- Introduced new class Graphic3d_CView.
This is a base class for render views.
Made possible to specialize concrete instances of the class by graphical driver.
- Moved all methods managing rendering views into interface of Graphic3d_CView.
The corresponding methods were removed from interface of graphical driver.
3) Eliminated Visual3d package:
- Logic of managing display of structures was put from Visual3d_ViewManager into Graphic3d_StructureManager.
- Removed Visual3d_View class. Logic of managing computed structures was put into base layer of Graphi3d_CView.
- Removed all intermediate structures for storing view parameters e.g. Visual3d_ContextView.
All settings are kept by instances of Graphic3d_CView
- Removed Visual3d_Light intermediate class.
All light properties are still stored in Graphic3d_CLight structure.
The structure is directly access by instance of V3d_Light classes.
- Moved all needed enumerations into Graphic3d package.

Make modification to save in the file part of the XCAF document starting from specified label.
If specified label is component of the high-level assembly then high-level assembly is saved in document with one specified component.
In other case only part of the document starting from the specified label is saved.
0026419: [Regression?] Export of a reversed face leads to crash in 6.9.0 although proceeded in 6.8.0
Take basis surface from trimmed surfaces during IGES writing, because pcurves will be transformed, so trim will be shifted, accorded to new face bounds,
fix updating of seam edge,
change condition of using Segment during exporting periodic BSpline surfaces to IGES (if bounds are not in one period).

Modification to support case when edges on face have incorrect orientation was added.
Modification to support case when wires have intersecting segment was added
Test cases for issue 25553 added; other affected tests corrected (improvements)
XSAlgo_AlgoContainer is corrected to return original shape if Shape Processing fails.
Handling of situation of absence of defined operator sequence is corrected to apply DirectFaces operator by default on writing, regardless of target format.
ShapeProcess is corrected to output warning if operator sequence is not defined in resource file, and to continue if one operator in sequence has failed.
Message names are made more meaningful.

Output message if texture dimension exceed the max dimension. Texture initialization is fail in this case.
TKOpenGl does not depends on deprecated GLU anymore.

Old vright equals new vfront, old vfront equals new vright, old vleft equals new vback, old vback equals new vleft.
