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.
