The circle is specified by either a valid QGeoBoundingCircle instance or a

metres respectively.
The circle may appear as an ellipse on maps which use the Mercator
projection. This is done so that the circle accurately covers all points at
a distance of the radius or less from the center.

The route is specified by a QGeoRoute object.
The route might be quite detailed, and so to improve performance the
detail level can be set with QGeoMapRouteObject::detailLevel.
The route object draws the route as a series of lines with a minimum
on-screen harmattan length equal to the detail level. This is done so that
the small changes in direction of a road will be visible at high zoom
levels but will not slow down the rendering at the lower zoom levels.
