The name stack is used during selection mode to allow sets of rendering
commands to be uniquely identified. It consists of an ordered set of
unsigned integers. ggggllllLLLLooooaaaaddddNNNNaaaammmmeeee causes _n_a_m_e to replace the value on the
top of the name stack, which is initially empty.
The name stack is always empty while the render mode is not GGGGLLLL____SSSSEEEELLLLEEEECCCCTTTT.
Calls to ggggllllLLLLooooaaaaddddNNNNaaaammmmeeee while the render mode is not GGGGLLLL____SSSSEEEELLLLEEEECCCCTTTT are ignored.
