Added new toolkit TKIVtk:
- TKIVtk toolkit includes IVtkVTK, IVtkTools, IVtkOCC, IVtk packages.
- TKIVtk provides OCC interface for VTK library functionality: it allows to use VTK window and event managment for OCC objects (shapes)
Porting on VTK 6:
- shape source inherits vtkPolyDataAlgorithm now (vtkPolyDataSource was removed form VTK as deprecated functionality).
- added factory auto-initialization in IVtkVTK_View
- remove using of deprecated methods of pipeline mechanism.
Get rid from warning in SelectMgr_SelectableObject. Removed firendship from SelectMgr_SelectableObject.
Corrected projector parameters for selection algorithm.

Each PrsMgr_PresentableObject has list of PrsMgr _PresentableObject called myChildren.
Transformation PrsMgr_PresentableObject applied to its children every time when its own transformation affected. This hierarchy does not propagate to Graphic3d level and below.
PrsMgr_PresentableObject send its combined (according to hierarchy) transform down to Graphic3d_Structure.
AIS_ConnectedInteractive and AIS_MultiplyConnectedInteractive are reused but behavior has been changed.
AIS_ConnectedInteractive now is an instance of object. It reuses geometry of connected object but have own transformation, material, visibility flag etc. This connection propagated down to OpenGl level to OpenGl_Structure. For this task old “connected” mechanism has been reused.
AIS_MultiplyConnectedInteractive represents assembly which doesn’t have its own presentation. Assemblies are able to participate is scene hierarchy and intended to handle a grouped set of instanced objects. It behaves as single object in terms of selection. It applies high level transform to all sub-elements since it located above in the hierarchy.
All AIS_MultiplyConnectedInteractive are able to have child assemblies. Deep copy of object instances performed when one assembly attached to another.

0024915: Wrong intersection curves between two cylinders
Existing method of Cylinder-Cylinder intersection computing is based on finding the analytic line (as a function of one argument) and converting one into the walking-line with set of equidistant (along the line parameter) points.
The main advantage of applied method is using adaptively computed step. Necessary step is computed into every point of the obtained walking-line. At that we receive final walking-line directly (without preliminary analytic line) and we determine moments more precisely, when it should be split (see IntPatch_ImpImpIntersection_4.gxx).
The main disadvantages is bad working this method for non-trimmed cylinders (with infinite bounds), because step value is depend on the boundaries values.
More over, new method always returns walking-line, while intersection result can be an analytic curve (lines, circle, ellipse). That is NO good. Therefore, analytic curve is computed by existing method.
In conclusion, in spite of covering almost all more often meeting cases, new method has limited application. Then we should use the existing old method.
Additionally, method MinMax() is added (see Standard_Real.hxx file). It uses into new algorithm.
Some test cases is changed according to their new behavior.
Test case for issue CR24915 is added.

1) Add SelectMgr_EntityOwner::IsSelected() and SelectMgr_EntityOwner::SetSelected() methods to determine if corresponding entity is selected.
They replace functionality of SelectMgr_EntityOwner::State() methods that are deprecated now.
2) AIS_InteractiveContext::ToHilightSelected() and AIS_InteractiveContext::SetToHilightSelected() is to be used to enable highlighting of selected objects.
3) By default selected objects are highlighted (new behavior)
4) Add ViewerTest_ViewerCommands: vhighlightselected command to enable/disable 'highlight selected objects' mode.
5) AIS_LocalContext, AIS_InteractiveContext : style changes in Select and ShiftSelect methods.
6) Add test cases /bugs/vis bug23649_1 and /bugs/vis bug23649_2 to test highlighting of selected objects in local context.

0025057: Message_Algorithm fails to find messages defined for base class
New method HasMsg() is added in Message_MsgFile class to check if message with given key is registered.
That method is used in Message_Algorithm to check if message is defined on given level of class hierarchy.
Generation of error message in Message_MsgFile::Msg() is revised: now it includes a message key and gets added to the registry, to avoid re-generation in case of multiple requests.
Access to message registry maintained by the Message_MsgFile class is protected from concurrent access by mutex.
The patch changes the algorithm of choosing the initial approximation for Newton's method. Instead of searching for a point on the fine shifted grid, the algorithm performs initial search for candidate points in the original coarse grid (which is cached in new version). After that particle swarm optimization (PSO) is used to localize the global minimum. This algorithm optimizes a problem by having a population of candidate solutions ("particles"), and moving these particles around in the search-space according to simple mathematical formula over the particle's position and velocity. Each particle's movement is influenced by its local best known position but, is also guided toward the best known positions in the search-space, which are updated as better positions are found by other particles. This strategy has reported good results in solving complex global optimization problems.
Current patch implements initial version of PSO for using in Extrema_GenExtCS class. Typically new approach allows to reduce the number of evaluations by 5-10 times. There are only few cases there the numbers of evaluations are comparable.
