       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.

       None.
