This little patch makes it a lot smoother the pull around the map.
Updating it while moving, to keep the rails from disappearing.
Zooming still acts a bit weird, only updating after completion of a zoom.
Maybe try the zoom event instead of the zoomanim event?
I tried, same result. Even tried hooking into the zoom to update it by hand.
Seems like there is something going on with polylines and the zoom that I don't quite understand.
The other change works great tho.
