0028954: Visualization - implement interactive object for camera manipulations

Added new class AIS_ViewCube implementing interactive cube
displaying orientation of the main axes of the model space in the viewer.
Each side, edge, or corner of the cube corresponds to particular orientation of the camera,
and the class provides methods to move the camera to corresponding position (with animation if needed).

AIS_InteractiveContext::LastActiveView(), added new property returning the last View processed by MoveTo() event.
AIS_InteractiveContext::BoundingBoxOfSelection(), added method returning bounding box of selected objects.
SelectMgr_EntityOwner::HandleMouseClick(), added new callback for handling
mouse clicks by owner itself without automatic highlighting and clearing previous selection.
Called by AIS_InteractiveContext::Select() method.

AIS_ViewController::ViewAnimation() has been extened with camera animation propery,
which can be bound to AIS_ViewCube for smooth embedding into event loop.

Prs3d_ToolDisk has been extended with parameters specifying angle range.
Graphic3d_MaterialAspect now initializes all coefficients to 1.0
when Graphic3d_NOM_UserDefined is passed to class constructor.
AIS_AnimationCamera::update() now sets the end camera position if animation duration is 0.
Prs3d_DatumAspect, added missing setters.

New command vviewcube has been added.

V3d_Viewer::AddZLayer() has been replaced by
V3d_Viewer::InsertLayerBefore() and V3d_Viewer::InsertLayerAfter() methods
allowing to specify Layer settings and index of existing layer to insert new one before/after.
The behavior of V3d_Viewer::AddZLayer() has been adjusted to append
new Layer before Graphic3d_ZLayerId_Top
(between Graphic3d_ZLayerId_Default and Graphic3d_ZLayerId_Top).

Graphic3d_Layer now provides LayerId() property.
Graphic3d_ZLayerSettings has been extended with IsRaytracable() property;
Ray-Tracing now processes multiple layers instead of Graphic3d_ZLayerId_Default.

Moved some methods from OpenGl_View to the base class Graphic3d_CView.

0030507: Visualization - introduce AIS_ViewController

ViewerTest_EventManager now inherits AIS_ViewController.
Platform-dependent user input handling within ViewerTest has been revised
to process events in common way through AIS_ViewController.
The mouse navigation has been changed, so that left mouse clicked
without modifers now rotates View.
The rubber-band selection can be activated via Alt+LeftMouseButton.
Selection is now done on mouse unclick and keyboard short-cuts take effect on unclick.

Aspect_Window::SetTitle() - added new method configuring Window title.
Introduced new types Aspect_Touch, Aspect_VKey, Aspect_ScrollDelta
for processing window events in platform-independent way.

0030726: Visualization - change Selected state of owner in AIS_Selection

AIS_InteractiveContext::IsHilighted() behavior has been changed.
It should use the same logic for owner processing like when it is highlighted. IsSelected of owner is used for selection state, not highlight.

 Without this correction, object is never shown as selected by click (Select(bool)):
 if (!HighlightStyle (theOwner, aCustomStyle) ||
    (!aCustomStyle.IsNull() && aCustomStyle != anObjSelStyle))

 IsSelected is already true, so the highlight style is equal to selection style, nothing to do.

OSD_Path::FolderAndFileFromPath(), ::IsRelativePath(), ::IsAbsolutePath().

V3d_TypeOfOrientation enumeration has been extended with aliases
(like front/left) for Z-up and Y-up conventions.
V3d_View::SetProj() now accepts argument for asking Y-up instead of Z-up.

Added command vviewproj defining standard camera direction.
Commands vaxo, vleft, vright, vtop, vbottom, vfront, vbottom now redirect to vviewproj.

0030655: Modeling Data - Provide interfaces for selection of the elements from BVH tree

Provide the easy to use interfaces for selection of the elements from BVH tree.
The selection rules should be implemented in the selector class derived from *BVH_Traverse* or in *BVH_PairTraverse* in Reject/Accept methods.

The *BVH_Traverse* is used for selection of the elements from the tree.
The *BVH_PairTraverse* is used for selection of the pairs of elements from two BVH trees.

Auxiliary changes:
- Two methods BVH_Box::IsOut(OtherBox) and BVH_Box::IsOut(Point) have been added;
- Added methods for conversion of Bnd boxes to BVH boxes

Added new class *BVH_Tools* containing useful static methods operating on BVH points and boxes.

The classes BRepExtrema_OverlapTool and BVH_DistanceField have been rebased to use the new traverse methods.

Removed auxiliary class PrsMgr_ModedPresentation holding Structure and Display Mode index (field has been moved to Structure itself),

0030645: Modeling Algorithms - B-spline segmentation produces wrong parametrization

Method Segment() of B-spline curve and surface has been extended by parameter theTolerance (theUTolerance and theVTolerance for surface), which defines the proximity between knots of a NURBS and boundaries of cutting segment. The default value of the tolerance is Precision::PConfusion().
Test cases have been added to check segmenting of B-spline surface and curves both 2D and 3D.
