a #ChamplainBoundingBox
Makes a copy of the bounding box structure. The result must be freed using champlain_bounding_box_free().
Checks whether bbox covers the given coordinates.
the latitude of the point
the longitude of the point
Extend the bounding box so it contains a point with latitude and longitude.
Do nothing if the point is already inside the bounding box.
the latitude of the point

Gets the center's latitude and longitude of the box to latitude and longitude.
Checks whether bbox represents a valid bounding box on the map.
