201c22081b 0025076: Hidden overloaded virtual functions
Implementation of virtual functions is made more consistent in places where warning was issued:

- Missing implementation of virtual method Closed() added in classes inheriting Intf_Polygon2d
- Empty implementation of virtual method Read() accepting stream is moved from PCDM_RetrievalDriver to StdLDrivers_DocumentRetrievalDriver
- Method BRepFill::Delete() is renamed to DeleteProfile() to avoid confusion with method Delete() inherited from MMgt_TShared
- Virtual method AIS_Dimenaion::ComputePlane() is removed from base class; each dimension defines and uses its own method with the same name (but different arguments)
- Inherited virtual method Dump() with single argument in class XCAFDoc_ShapeTool is now defined as short-cut to own method Dump(), also calling parent's one
- Inherited virtual method BoundingBox(void) is made visible in AIS_Shape
- Inherited virtual method Box(void) is made visible in classes inheriting BVH_PrimitiveSet

3bf9a45f7a 0026195: Visualization - optimize selection algorithms
- initial transformation of triangulation is now applied to selecting frustum;
- switched from NCollection_Vec3 to gp collections to avoid conversions and usage of macros;
- calculation of frustum was refactored to reduce its build time;
- double pixel tolerances for selection were replaced by integer ones;
- switched to splitting along the main axis only in SelectMgr BVH selection primitive sets.

825aa485a3 0026344: Visualization - provide a support of zoom persistent selection
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.

7ab159522a 0026069: Coding Rules - eliminate new warnings about redundant const qualifier in SelectMgr
SelectMgr_SensitiveEntity is now inherited from Standard_Transient;
Redundant const type qualifiers were removed from selection classes.

f751596e46 0024623: Visualization - improve selection mechanism
Redesign of selection mechanism:
- implemented 3-level BVH tree for selection;
- selection now calculates in 3D space;
- intersection tests were moved to SelectMgr_BaseFrustum descendants;
- removed .cdl files in Select3D and .cdl related to selection in MeshVS;
- SelectMgr_ViewerSelectors are now shared between local and global contexts;
- transformations of sensitive entities are now stored in SelectMgr_SelectableObject only. Sensitive entities are independent from transformations, it is applied to SelectMgr_SelectingVolumeManager instance only;
- connected and multiple connected interactive objects are now represented by their child objects only for SelectMgr_SelectionManager;
- if interactive object has child objects, they will be stored as separate objects in SelectMgr_SelectionManager now.
- test cases bugs/vis/bug24623_1, bug24623_2, bug24623_3, bug24623_4 to test performance and memory issues.
