It would be useful to display an MKPolyline for driving directions which is colored according to the traffic at that line. Otherwise, the polyline covers the traffic information.

Steps to Reproduce:
I'd like to display a driving directions route polyline which is colored according to the traffic.

Expected Results:
I should be able to display a driving route line exactly as in

Actual Results:
There's no way to access the underlying traffic information of the map (if `showsTraffic` is enabled) in order to use them for a polyline.


It would be desirable that the polyline renderer can still configure a base color for the line which is used in case there's no or green traffic. Only for orange or red traffic, the traffic color should override.
