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.
