16fa0dfb08 0023488: Make video recording functionality (OpenGl_AVIWriter) optional
CSF_AviLibs missing in EXTERNLIB of TKOpenGl toolkit. This cause incorrect project generation.
HAVE_VIDEOCAPTURE now should be defined to enable video recording capabilities on Windows.

5e27df788d 0023226: Extend OpenGl_Context to store map of shared GPU resources
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+).
Strange workarounds for feedback mode were removed.

OpenGl_Context now provides access to shared GPU resources
and manages resources queue for delayed release
(replaces functionality of removed OpenGl_ResourceCleaner).
Loaded GL_ARB_texture_buffer_object and GL_ARB_draw_instanced extensions.

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.

New classes NCollection_Vec2, NCollection_Vec3 and NCollection_Vec4
implements interface to low-level data (points, vertices, colors) in GLSL-style.
Removed EnableVBO argument from vdrawparray Draw Harness command
Corrected compilation errors
Fixed wrong argument in Index VBO initialization
Fixed several cases of incorrect memory management in TKV3d

Visual3d_ViewManager::Remove()
Destroy structures before last view removed for correct GPU resources management.

Graphic3d_Structure::GraphicClear()
Remove groups to avoid usage of dead OpenGl_Group pointers.

V3d_View::Remove()
Fixed mistake in #0000280 patch.
Small correction
Fixed OCC280 test command

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.

5f8b738ea5 0023022: This is desirable to access OpenGl extensions and core API (1.2+) in one place
Extend OpenGl_Context to provide GL2.0 core functionality

Added 'glext.h' header provided by Khronos group with definitions
and GL functions' types.
Added OpenGl_GlCoreXX structures with function list
to appropriate GL core functionality.
Fixed memory leak in OpenGl_Context destructor.
Eliminate inclusions of gl.h header
Use OpenGl_GlCore11.hxx instead.
Removed obsolote M_PI redefinitions.
Slightly cleaned up included headers.
Reuse definitions from glext.h
OpenGl_ArbVBO and OpenGl_ExtFBO originally provide own definitions
for OpenGL extensions.
