Avoid Redraw() into FBO without ImmediateModeDrawToFront flag.
PrsMgr_PresentationManager stores list of temporary immediate presentations,
automatically cleared within BeginImmediateMode() call.

- 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.

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.
- OpenGl_Display - release GL resources correctly on closing views
- OpenGl_AspectFace, OpenGl_AspectText, OpenGl_AspectLine, OpenGl_AspectMarker - initialize OpenGl resources on demand, when context is available.
- Graphic3d_TextureRoot - use const modifier for GetId method to avoid asynchronous resource state at OpenGl.
- Do not call OpenGL functions if no active GL context has been left
- Reset thread's context before deletion for Mesa WNT
Fixed graphic structure recompute after closing view.
Removed collector and all corresponding logic and methods from AIS_InteractiveContext.
Method AIS_InteractiveContext::Erase() now hide object from viewer without deleting resources.
Erased objects now properly recomputed after closing view.
Samples update
Removed useless method AIS_InteractiveContext::EraseMode()
Documentation update
Warnings fix
Regressions fix
Graphical clipping:
- Use "Graphic3d_ClipPlane" to defined clipping for PrsMgr_PresentableObject (local clipping), for V3d_View (global clipping).
Get rid of old implementations:
- Remove Visual3d_ClipPlane.
- Port V3d_Plane to Graphic3d_ClipPlane core.
Selection Sensitives:
- Port "Matches" method to add full set of arguments (SelectBasics_PickArgs), including min-max depth coming from selector.
- Get rid of transient data for pair Matches -> ComputeDepth.
- Extend SelectMgr_ViewerSelector::LoadResult to work with local clipping, add virtual callbacks to compute globa/local depth clipping for picking.
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.
- Added "vsettexturemode" command for changing texture details in views (enable / disable textures).

OpenGl_Texture::Init() - check gluBuild2DMipmaps() return value
OpenGl_Texture - check GL_BGRA_EXT for compatibility

OpenGl_Texture - added missing break statement for ImgBGR32 case
OpenGl_Workspace::setTextureParams() - fixed local variable aFilterMin overrides visibility of early declared variable
OpenGl_Workspace::DisableTexture() - reset texture matrix
FTGL do not reset texture matrix and corrupt text could be rendered if custom texture has not identity texture matrix.
OpenGl_PrimitiveArray::Release() - avoid possible NULL-pointer dereference
OpenGl_GraphicDriver::RemoveView() - release GL resources within removing last view
Fixed OCC280 test command - do not remove old view until new one is initialized
A new class Image_Diff for comparison of images
and a draw-command "diffimage", which compares 2 images.
Image_PixMap redesigned to provide interface for low-level image operations.
New Image_AlienPixMap class now intended for Save/Load functionality.

OpenGl_Resource was slightly corrected and OpenGl_Element was extended
with Release method to manage GPU resources.
OpenGl_PrimitiveArray now uses new OpenGl_VertexBuffer class (requires OpenGL 1.5+).

and manages resources queue for delayed release
(replaces functionality of removed OpenGl_ResourceCleaner).

Global maps of views, workspaces and structures
were moved to OpenGl_GraphicDriver members.
UserDrawCallback() function moved to OpenGl_GraphicDriver methods.
Aspect_GraphicCallbackStruct now holds handle of OpenGl_Context
instead of system-dependent pointers to GL context definition.

Replace removed view within created one in ViewerTest EventManager.
ViewerTest, do not create unused 3D view
In current design NIS_View always created and used for both - NIS objects and AIS objects.
myIsUpdated flag and Invalidate() method removed from OpenGl_Workspace class.
View redrawing is made unconditional.
V3d_View::Update() becomes deprecated and should be replaced with V3d_View::Redraw().
