_D_e_t_a_i_l_s:

     RGL holds two stacks. One is for shapes and the other is for
     lights.  'clear3d' and 'rgl.clear' clear the specified stack, or
     restore the defaults for the bounding box (not visible) or
     viewpoint.  'rgl.pop' removes  the top-most (last added) node on
     the shape stack.

     Note that clearing the light stack leaves the scene in darkness;
     it should normally be followed by a call to 'rgl.light' or
     'light3d'.
