    \brief The MapRectangle element displays a rectangle on a map.
    \inherits QGeoMapRectangleObject

    \ingroup qml-location-maps
    \since Mobility 1.2

    The rectangle is specified in terms of the top left and bottom
    right coordinates.

    If \l topLeft and \l bottomRight are not specified and valid the
    rectangle will not be displayed.

    An example of one big yellow rectangle:
    \snippet doc/src/snippets/declarative/testpolymapobjects.qml MapRectangle

    The MapRectangle element is part of the \bold{QtMobility.location 1.2} module.
