Draw paths on maps

[Altreus]

Splendid as the cartographical art is in this game, I have to feel that if I were wandering around a frozen wilderness, scratching rough guides for myself with salvaged charcoal, I would probably mark trails and paths on the map as well.

Since we don't have a player marker on the map in survival mode, having some idea of where I am amongst the stylised rocks because I'm sticking to a path would be extremely helpful. My specific case was wandering up the top level of Ash Canyon, where there's a very obvious path along the edges of cliffs, and I would probably draw that on the map if I were there.
