    \brief The MapRoute type displays a Route on a Map.
 
    The MapRoute type displays a Route obtained through a RouteModel or
    other means, on the Map as a Polyline following the path of the Route.
 
    MapRoute is really a \l MapPolyline, but with the path specified using the
    \l route property instead of directly in
    \l [QtPositioning]{geoCoordinate}{coordinates}.
 
    By default, the route is displayed as a 1-pixel thick black line. This can
    be changed using the \l line.width and \l line.color properties.
 
    \section2 Example Usage
 
    Here is how to draw a \l{route}{route} on a \l{Map}{map}:

/*!
    \qmlpropertygroup Location::MapRoute::line
    \qmlproperty int MapRoute::line.width
    \qmlproperty color MapRoute::line.color
 
    This property is part of the line property group. The line
    property group holds the width and color used to draw the line.
 
    The width is in pixels and is independent of the zoom level of the map.
    The default values correspond to a black border with a width of 1 pixel.
 
    For no line, use a width of 0 or a transparent color.
