[Qt-qml] MapPolyline

[david.laing at nokia.com]

Hi Sampo,

Dynamic adding / removing of map objects or coordinates in polygons / polylines is currently quite a painful exercise.

The present QML bindings for the Maps and Navigation API aren't final though, and that's something we're hoping to address pretty shortly.

There is already some interest in this on the qt-mobility-feedback list, so I'll probably post something there when the bindings are finished and available from the public git repository.

Cheers,

Dave
