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
