    \property QGeoMapObject::zValue
    \brief the z-value of the map object.

    The z-value determines the order in which the objects are drawn on the
    screen.  Objects with the same value will be drawn in the order that
    they were added to the map or map object.

    This is the same behaviour as QGraphicsItem.
