Initializes the OpenGL layer of IceT .icetGLInitialize must be called before any other function starting with icetGL (except icetGLIsInitialized).
Management for the OpenGL layer is held in the state of the current IceT context. Thus, icetGLInitialize must be called once per IceT context. If you are using a context for rendering with OpenGL ,it is recommended that you call icetGLInitialize immediately after calling icetCreateContext.
icetGLInitialize is called twice for the same context.
