    \brief Provides support functionality for map display with QGeoServiceProvider.
 
    \note There are no source or binary compatibility guarantees for the
    backend classes. The API is only guaranteed to work with the Qt version it
    was developed against. API changes will however only be made in minor
    releases. (6.6, 6.7, and so on.)
 
    The QGeoMappingManagerEngine class provides an interface and convenience
    methods to implementors of QGeoServiceProvider plugins who want to
    provide support for displaying and interacting with maps.
