The new transform persistence mode, with flag `Graphic3d_TMF_OrthoPers`, can be combined (bitwise OR operation) with the other persistence modes (2D, Trihedron or Zoom/Rotate Persistence) to make objects be rendered with orthographic projection when it is on a view with perspective projection.
If the view already uses orthographic projection, there will be no difference.
This feature was implemented to fix ViewCube being distorted when view with perspective projection changes size.

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
vselect/cone_cylinder/hollow_cone_cyl
Fix incorrect value of axis intersection with segment inside of SelectMgr_AxisIntersector::raySegmentDistance().
Move camera definition to base intersector (it is not possible to set it for axis intersector, is is not applicable).
Add method Graphic3d_Camera::SetIdentityOrientation() to set camera parameters to make current orientation matrix identity one.
Remove all matrices from selection intersectors and frustum builder and use camera instead of them.
Fix missed axis tests in vselect grid.
Deprecated Overlaps() methods have been moved from subclass SelectMgr_SelectingVolumeManager
to the base class SelectBasics_SelectingVolumeManager,
so that they are actually accessible within Select3D_SensitiveEntity::Matches() implementations.
Several methods have been marked as pure virtual in the base interface.
Second SelectMgr_BaseIntersector::OverlapsPolygon() has been dropped from virtual interface
as useless (trivially replaceable).
Fixed regression of SelectMgr_ViewerSelector::SetPixelTolerance(). Removed redundant myToUpdateTolerance flag.
SelectMgr_AxisIntersector::raySegmentDistance() - fixed usage of SquareModulus() instead of Modulus().
SelectMgr_ViewerSelector::TraverseSensitives() now skips both BVHSubset_2dPersistent and BVHSubset_3dPersistent relying on Camera.
AIS_ViewController::handleXRMoveTo() now uses interface for picking by Axis explicitly
instead of emulating axis by point picking.
