1372b56bc2 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.

bf3977c9f9 0026146: Visualization, Select3D_ISensitivePointSet - eliminate crash when clearing selections [only with TBB]
Remove classes Select3D_ISensitivePointSet and Select3D_BoundarySensitivePointSet; use Select3D_SensitivePoly directly for boundary selection.
Make last argument in Select3D_SensitiveFace non-default to ensure that value is always explicitly specified by the caller.
Inherit SelectMgr_FrustumBuilder from Standard_Transient to use normal Handle instead of NCollection_Handle.

Add test case bugs/vis/bug26146.

2157d6ac63 0026147: Visualization - restore the ability to pick only fully included objects in rectangular selection
2 modes of rectangular selection are available: inclusion-only and overlap-allowing;
The modes can be switched using method AllowOverlapDetection from StdSelect_ViewerSelector3d;
BVH for sensitive entities now builds if there is more than max number of leafs in collection;
Added option -allowoverlap to command vselect;
Interactive rectangular selection in Draw is now available in 2 modes:
- if the user starts selection from upper corners, only fully included objects will be selected;
- if the user starts selection from lower corners, both partially and fully overlapped objects will be selected.

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.
