7aaed2ce3b 0032547: Visualization, Select3D_SensitiveCylinder - implement picking of a hollow cylinder
Select3D_SensitiveCircle now inherits directly from Select3D_SensitiveEntity.
The sensitive circle sector is created using the Select3D_SensitivePoly class directly.

Added appropriate methods for selecting sensitive circles.
Added parameter myIsHollow to Select3D_SensitiveCylinder class.
It allows you to search for intersections with cylinders without covers.

The Draw vcircle command has been extended with UStart and UEnd parameters
to create a sector of a circle.

Added tests: vselect/cone_cylinder/circle_sector
             vselect/cone_cylinder/circle_wire
             vselect/cone_cylinder/filled_circle
             vselect/cone_cylinder/transformed

bc73b00672 0031313: Foundation Classes - Dump improvement for classes
- Provide DumpJson for geometrical, ocaf and visualization classes;
- Change depth parameter of DumpJson (constant is not obligate here)
- Introduce a new macro for transient objects to be called as the first row in DumpJson: OCCT_DUMP_TRANSIENT_CLASS_BEGIN. We need not put the class name in the macro, using get_type_name of Standard_Transient for it.
- change implementation of OCCT_DUMP_CLASS_BEGIN and OCCT_DUMP_TRANSIENT_CLASS_BEGIN. It is not an sentry more and it does not create a new hierarchy level. It appends a new row into the output stream: "className": <className>
- OCCT_DUMP_* does not require semicolon

099f351396 0027739: Visualization, TKV3d - implement individual acceleration data structure for selection of 2D persistent objects
Low-level selection algorithms has been improved to explicitly support 2D
transformation persistent objects. This patch generally touches:

1) SelectMgr_SelectableObjectSet - the lists of objects has been split onto three
subsets (regular, 3d-persistent, 2d-persistent). Each subset has individual BVH
tree. The algorithms are now have more flexibility to update only those trees
that is really required for actual camera state.

2) SelectMgr_ViewerSelector - explicitly supports Eye space selection operations
on BVH tree for 2d-persistent subset. Change of camera position does not
anymore affect acceleration data structure (BVH tree) of 2d-persistent selectable objects.

3) Other classes from SelectMgr have been fine-tuned to provide appropriate API.

Porting notes:

This patch touches very low-level selection classes. If the low-level features were used
the following modifications may need to be considered for porting:

1) Iteration over objects of SelectMgr_SelectableObjectSet should now
be implemented with corresponding Iterator class.

2) SelectMgr_BaseFrustum::ScaleAndTransform and derived classes return
Handle(SelectMgr_BaseFrustum) instead of NCollection_Handle<> type.

114b7bf18f 0027180: Visualization - improve selection logic of MeshVS_Mesh
MeshVS_Mesh selection logic in MeshVS_SMF_Mesh mode (entire mesh) has been optimized.
MeshVS_Mesh::ComputeSelection() now creates single sensitive entity
MeshVS_CommonSensitiveEntity (new class) instead of small sensitive entity on each element.
MeshVS_SensitiveQuad (new class) and Select3D_SensitiveTriangle are used instead of Select3D_SensitiveFace for local selection to reduce memory consumption when possible.
