Improve consistency and visual appearance of predefined OCCT materials in various rendering modes, including ray-tracing:
- Increase the specular exponents (shininesses) for metallic surfaces: Brass, Bronze, Copper, Gold, Pewter, Silver, Steel, Chrome, Aluminum.
- Revise specular colors for metals: Copper, Gold, Aluminum, Silver (according to "Real-Time Rendering, 3rd Edition", AK Peters 2008).
- Increase diffuse reflection of metals: Silver, Aluminum, Chrome (to make them brighter in OpenGL mode).
- Extend Material definition by Refraction Index.
Advanced rendering methods based on shaders or ray-tracing can utilize it to produce refraction effects.
In addition:
- Introduce three translucent materials: Water, Glass, and Diamond.
- Add Charcoal for modeling dark diffuse surfaces.
Add new TCL-based sample (materials.tcl) and test case (tests/v3d/materials/bug24855).
Redesign Graphic3d_ArrayOfPrimitives
Store vertices data in buffer objects managed using smart-pointers
- no more low-level memory corruption by memory releasing after VBO creation.
Remove broken hasEdgeInfos.
Interleave vertex attributes (position, color, normal, uv) in single buffer.
Remove from Graphic3d_ArrayOfPrimitives methods ::Orientate().
Remove structures Graphic3d_PrimitiveArray, CALL_DEF_PARRAY.
Add support for 2D vertex arrays.
Graphic3d_Group - remove array or primitive arrays.
Introduce more universal method Graphic3d_Group::AddPrimitiveArray().
Fix warning
Graphic3d_Group is now abstract class and should be instantiated
using Graphic3d_Structure::NewGroup() method.
Graphic3d_CGroup has been removed.
The groups list is no more duplicated within Graphic3d_Structure and OpenGl_Structure.
Removed unused/duplicated fields from Graphic3d_Group.

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.
