Redundant methods Delete() and Desroy(), created in CDL as a hack to define destructor for the class, are removed; their definitions are converted to definition of destructors. In a couple of places methods Destroy() are preserved (bug made non-virtual) because they are called explicitly.
Add missing code for z-fit support for zoom, rotate persistent object.
Fixed wrong statement that should enable frustum culling optimization for zoom, rotate persistent object.
Fixed BVH_LinearBuilder.lxx to correctly control number of items in leaf node for a case of items with equal bounding boxes.
Added non-regression test case for z-clipping of transform persistent objects.
Graphic3d_CStructure::Transformation - use Graphic3d_Mat4 instead of plain arrays.
Drop duplicating field OpenGl_Structure::myTransformation (copy of Graphic3d_CStructure::Transformation).

OpenGl_Texture::Init2DMultisample() - new method to initialize multisampled texture.
Graphic3d_RenderingParams::NbMsaaSamples - add option defining MSAA samples number.
RayTracing will keep using FBO without MSAA, however it is possible to combine
MSAA for rasterization and FSAA for RayTracing.
OpenGl_FrameBuffer constructor has been changed to do not take arguments.
OpenGl_FrameBuffer::Init() method has been extended with mandatory parameters
defining Color and Depth attachment formats
and optional parameter defining number of MSAA parameters.
Draw Harness, add option -msaa to vrenderparams.
Added missing Standard_EXPORT for public methods; declaration of unimplemented method removed.
Restoring some changes made for #26788 but omitted in its commit.
OpenGl_View::ReadDepths() - drop obsolete and broken method; V3d_View::ToPixMap() should be used instead

- Added equality checks to camera modification methods to avoid camera updates when performing identity operations.
Update ViewerTest and VoxelDemo to not use UserDraw callbacks.
OpenGl_View::blitBuffers() - set 0 GLSL program after blit

Graphic3d_Group::UserDraw(), OpenGl_GraphicDriver::UserDrawCallback().

OpenGl_Text::FontKey() considers a resolution (PPI) now.
Add a new argument '-resolution' (sets a pixel density) in the 'VRenderParams' draw-command.
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.
4) Update package D3DHost to new changes.
5) Update code of OCCT samples to new changes.
- Graphic3d_Camera: comparison of real to zero by == is replaced by safer check against FLT_MIN (#25760)
- BRepBuilderAPI_Copy: new option copyMesh (#26458) is documented and made combinable with copyGeom
Classes Aspect_Clayer2d,OpenGl_GrahpicDriver_Layer, Visual3d_Layer, Visual3d_LayerItem, V3d_LayerMgr, V3d_LayerMgrPointer were deleted. Method OpenGl_GraphicDriver::TextSize() was moved to OpenGl_GraphicDriver.cxx.
Update V3d/FILES
Documentation updated.
Add new class Font_BRepTextBuilder for generation of formatted BRep text.
Delete method Font_BRepFont::RenderText(), which should be replaced by Font_BRepTextBuilder::Perform().
Interface_STAT.cxx - rename local variable 'stat' to 'myStat' to avoid name collision.
OSD_FileNode.cxx - pass correct argument to va_start().
STEPConstruct_AP203Context::DefaultDateAndTime() - use _get_timezone() instead of global variable timezone on msvc.
Graphic3d_ArrayOfPrimitives::VertexColor() - fix reinterpret_cast() argument.
Small correction: OCC26481-linesarc.brep is equal to bug26296_linesarc.brep
- picked or selected objects are now highlighted via owners instead of interactive objects;
- support methods for owners were added to AIS_InteractiveContext;
- dynamically highlighted owners are now displayed in immediate mode;
- selection without opening of local context is enabled by default;
- added "-local" key to vselmode command to enable selection in local context;
- selection filters are now completely supported in AIS_InteractiveContext;
- the idea of differencing of selected items onto current (in interactive context) and selected (local selection) was eliminated;
- all calls to "current" were replaced by calls to "selected" in terms of future local context removal;
- AIS_InteractiveObject::mySelectionMode was removed;
- now each selectable object can define own selection mode for "global" selection of the whole object;
- whole object selection mode is 0 by default for all standard interactive objects;
- immediate structures are now added to topmost and top layer lists;
- added support of drawing immediate structures in different layers;
- unused code for immediate mode was removed;
- vfeedback and vexport commands now produce correct output for raytrace mode.
1) New Graphic3d_TransformPers structure for defining parameters and algorithm methods, featuring:
a) application of transformation to projection and world view matrices;
b) computation of model-world transformation of persistent object;
c) computation of transformed bounding box of persistent object.
2) Transform persistence algorithm does not make any changes to model-world transformation of object (deals with projection and world view matrices only), thus making possible to employ local transformation in a usual way.
3) Support of BVH selection for transform persistent objects (pan, rotate, zoom, trihedron persistence only).
4) Support efficient frustum culling for transform persistent objects (pan, rotate, zoom, trihedron persistence only).
5) Support of z-fitting algorithm for world-view space transform persistent objects (rotate, zoom persistence only).
6) Rewrite usage of transform persistence structures and utilities classes:
a) Replaced Graphic3d_CTransPers, TEL_TRANSFORM_PERSISTENCE by Graphic3d_TransformPers;
b) Move functions from OpenGl_Utils.hxx to Graphic3d_TransformUtils.hxx;
c) Extract matrix stack class from OpenGl_Utils.hxx to OpenGl_MatrixStack.hxx;
7) New class Graphic3d_WorldViewProjState to keep track of projection, world view matrices changes for a camera.
8) New test case bugs/vis/bug26344.
9) Renamed method Graphic3d_Camera::ModelViewState of to ::WorldViewState for consistency.
