I need to draw a log of polylines on a TTMSFNCMap. Programatically, I then need to be able to modify the properties of the n-th polyline. In particular, I need to adjust the number and value of the points making up the polyline. I'm guessing that I need to execute `TTMSFNCMap.Polylines[n].Coordinates.Clear`

and then iteratively add to the `TTMSFNCMap.Polylines[n].Coordinates`

, but I'm not sure how.

I then also need to do the same thing with polygons. (I'm assuming there will be some commonality to the polylines answer)

Thanks!
