    popupMenu: changes rotation center of sub-menu's triangle
    
    When the triangle rotates (when sub-menu is expanded), it seems as if
    the triangle pivots from one corner even though rotation center is set
    to Clutter.Gravity.CENTER. Hence the rotation center is set nearer to
    the edge than to the corner ([0.3, 0.5] instead of [0.5, 0.5]) so that
    it doesn't appear odd.
    
    Also pivot_point is used instead of rotation_center_z_gravity as it is
    deprecated.
