AutoZFit operation now may be applied on Visual3d_View level.
Visual3d_View tracks Graphic3d_Structure updates and call AutoZFit within
Visual3d_View::Redraw if necessary.
In order to get AutoZFit functionality on Visual3d_View level ZfitAll
method moved from V3d_View into Graphic3d_Camera. AutoZFit method and
AutoZFitMode flag now part of Visual3d_View.

Redundant keyword 'mutable' removed in CDL files.
In IGESConvGeom_GeomBuilder, unused methods MakeXY() and MakeXYZ() removed.

Code previously using Set classes updated to equivalent use of Sequence (Adaptor3d and Visual3d packages) or TColStd_PackedMapOfInteger (BRepAlgo package).
In Adaptor3d_CurveOnSurface, calculation of continuity intervals refactored so as to build and store sorted sequence of reals, instead of collecting them to set, copying to array, and then sorting.

Global functions and class methods ShallowCopy() are removed; also removed unused classes Visual3d_PickPath and Visual3d_PickDescriptor.
Global functions and class methods ShallowDump() are removed, except for classes Standard_GUID, TopLoc_Datum, and TopLoc_Location as the latter are still used in some Debug printouts.

Prs3d_PresentationShadow - shadow link to existing presentation with custom attributes.
Graphic3d_Structure::Highlight() - do not register undisplayed structure in structure manager.
AIS_InteractiveContext, AIS_LocalContext add flag to prevent view update into methods
::MoveTo(), ::HilightNextDetected(), ::HilightPreviousDetected()
to allow update of customized immediate structures before redraw but after ::MoveTo().
Remove unused method AIS_InteractiveContext::Drag().
StdSelect_ViewerSelector3d do not user immediate mode in methods
::DisplayAreas(), ::ClearAreas(), ::ClearSensitive(), ::DisplaySensitive(),
GridEcho - update value in StdSelect_ViewerSelector3d::Pick() instead of V3d_View::Compute().
Do not use global variable for GridEcho vertex.
Redraw immediate mode not within GridEcho but at AIS_InteractiveContext, AIS_LocalContext layer.
V3d_View::ToPixMap() - disable autoupdate during FitAll.
Avoid Redraw() into FBO without ImmediateModeDrawToFront flag.
PrsMgr_PresentationManager stores list of temporary immediate presentations,
automatically cleared within BeginImmediateMode() call.
Methods with ambiguous names have been renamed
(new names now consistent with pre-existed method names in AIS_LocalContext class):
- BeginDraw -> BeginImmediateDraw
- EndDraw -> EndImmediateDraw
Remove now useless Remove() method (and ImmediateRemove() in AIS).
Visual3d_View now stores map of displayed immediate presentations.
ViewerTest_EventManager - eliminate double redraw in selection methods.
Fix warning
From now on, the panning behavior of V3d_View completely corresponds to equal operations with camera. There is no more confusing "Center" property and "ProjectionShift" which were used to introduce composite panning, while respecting view referential points: At, Eye unchanged. The V3d_View::FitAll approach has been rewritten to do "fit all" geometrically, operating with frustum, to make it working for both orthographic and perspective projections.
1) Getting rid of ProjectionShift and Center property:
- Removed ProjectionShift property of Graphic3d_Camera.
- Removed confusing Center property of V3d_View (related to projection shift).
- Removed redundant code related to the Center property of V3d_View.
- Removed WindowLimit method of Graphic3d_Camera - no more used.
2) Improvements of fit all and selector:
- Improved FitAll operation of V3d_View and reused it in NIS_View - the perspective projection is now handled correctly.
- Revised code of Select3D_Projector class - can be defined with any given projection and model-view matrices.
- Modified StdSelect_ViewerSelector3d and ensured that panning, zooming and going into the view do not lead to unwanted re-projection of sensitives. The handling of perspective selection is revised.
- Take into account graphical boundaries of infinite structure on ZFitAll.
3) Improvements of camera:
- Introduced new z range scale parameter for V3d_View::AutoZFit. See, V3d_View::AutoZFitMode.
- Allow negative ZNear, ZFar for orthographic camera to avoid clipping of viewed model.
- Moved camera ZNear, ZFar validity checks to V3d_View level.
- Use more meaningful Standard_ShortReal relative precision for ZNear, ZFar ranges computed by ZFitAll.
- Use Standard_Real type for camera projection and orientation matrices.
- Extended camera to generate both Standard_Real and Standard_ShortReal transformation matrices using the same matrix evaluation methods and converted input parameters.

of unused local variables, which makes it harder to find other
meaningful warnings.
This commit does not fix all unused local variables.
Fix new type conversion warning
Code cleaned to avoid MSVC compiler warnings on unused function arguments.
Several useless pieces of code are removed.

Eliminated warnings -Wswitch shown by gcc
Eliminated two new warnings about wrong initialization order
Eliminated warnings about unused functions.
A few more ICC warnings (type conversions) fixed
- The NCollection_Sequence (Graphic3d_SequenceOfHClipPlane) is used for handling ordered lists of clipping planes instead of NCollection_Set (Graphic3d_SetOfHClipPlane).
The purpose of this functionality is to bring a basic ray-tracing solution to existing OCCT visualization toolkit (TKOpenGL).
Currently ray-tracing visualization core supports sharp shadows, specular reflections, transparency and adaptive anti-aliasing.
However, the basis for all ray-tracing algorithms is versatile, allowing you to add new ray-tracing features easily (such as ambient occlusion).
All ray-tracing computations are performed on the GPU using OpenCL framework, allowing real-time rendering performance.
It is important to note, that real-time ray-tracing is possible using high-performance GPUs with support of OpenCL 1.1 and higher (such as NVIDIA GeForce 660 or ATI/AMD Radeon 7850).
When using low-end GPUs (such as NVIDIA GeForce 640) the ray-tracing performance may slow down significantly.
Therefore, even with NVIDIA GeForce 640 you can render scenes with the millions of triangles. The support of OpenCL-enabled CPUs and integrated graphics cards is not guaranteed.
Graphical clipping:

Capping rendering algorithm:
- Recursive rendering algorithm for OpenGl_Groups.
- Introduced Rendering filter for groups.
Clipping plane management in TKOpenGl:
- Added OpenGl_ClippingState to OpenGl_Context.
DRAWEXE commands:
- Ported "vclipplane" command for new approach.
