Gravel path 2m

Gravel path 2m

- path may sink under the terrain – remove it and draw it again
- its terrain conforming path, you cant elevate it when you click on node with move it.
- cant make more interesting edges, using rail shader and all i can work with is full gravel or full transparency :X
Known issues:
- 2m width
- ground segment only (dont have any ideas for elevated segment)
- theme gravel
