/*!
\qmlproperty geoshape QtLocation::Map::visibleRegion
This property holds the region which occupies the viewport of
the map. The camera is positioned in the center of the shape, and
at the largest integral zoom level possible which allows the
whole shape to be visible on the screen. This implies that
reading this property back shortly after having been set the
returned area is equal or larger than the set area.
Setting this property implicitly changes the \l center and
\l zoomLevel of the map. Any previously set value to those
properties will be overridden.
This property does not provide any change notifications.
