Methods: getGL

             * Before we can issue GL commands, we need to make sure 
             * the context is current and bound to a surface. 
            mEgl.eglMakeCurrent( mEglDisplay, mEglSurface, mEglSurface, mEglContext );
            GL gl = mEglContext.getGL();
            return gl;
         * Display the current render surface. 
         * @return false if the context has been lost.
