PositionCross class
A position unit that evaluates another position unit on the cross axis.
This position unit takes a position unit and evaluates it on the perpendicular axis. For example, if used in horizontal positioning, it evaluates the wrapped unit in the vertical direction, and vice versa. This is useful for coordinating positions across both axes.
