\class QGeoMapObjectInfo
\brief The QGeoMapObjectInfo class is the base class used to define the
parts of QGeoMapObject and its subclasses that are specific to a
particular QGeoMapData subclass.
\inmodule QtLocation
\ingroup maps-impl
Most of the mapping functionality is provided by a QGeoMapData subclass,
including the rendering of the map itself.
This means that QGeoMapData subclasses need to be able to render each of
the QGeoMapObject instances and instances of the QGeoMapObject subclasses.
Furthermore, the need to be able to create and manipulate map objects
independently from the QGeoMapData instance precludes the use of a set of
factory methods for creating QGeoMapData specific map objects.
The QGeoMapObjectInfo class is used to provide the QGeoMapData subclass
specific behaviours for the map objects in a way which fulfils this need,
as the QGeoMapObjectInfo instances are only created at the point when a
map object becomes associated with a QGeoMapData subclass - which is most
commonly when the object is added to a QGraphicsGeoMap.
