Could someone explain why NeHe switched from the orginal base code window creation to the below source? (minus other code dependent on this code) Why the switch from everything in CreateWindowGL(...)? The OpenGL Game Programming book also does this. Any help would be great. Thanks!

      
...
case WM_CREATE:
{
	CREATESTRUCT* creation = (CREATESTRUCT*)(lParam);
	window = (GL_Window*)(creation->lpCreateParams);
	SetWindowLong (hWnd, GWL_USERDATA, (LONG)(window));
}
...
