1.26.5 Restoring trails
Trails are cancelled and restarted whenever the range is changed. However, you can continue
trails on the same range, without restarting, when the range is changed to a next larger or smaller
range scale. Note however that when the range is changed, only those target trails within the
previous range are continued; no trails are generated for targets outside of the previous range.
