Comment 8 for bug 951554

> I would also like to suggest the opposite kind of terrain: A terrain that can be passed by both ships and humans.

Hmm, i don't know... water could be passed with ships, but where ships could pass, normally a human couldn't pass. The only exception are bridges, where ships could pass beneath and humans could cross the water.

> Currently, we can create the impression of carriers walking through water (when two neighboring nodes are land, but the two triangles inbetween are water), but then, ships cannot pass.

For those situations the roads should be shown as footbrigdes (see second picture in https://wl.widelands.org/forum/post/12474/)

I am currently working on something like shallow water, or something that looks like a sandbank. See https://wl.widelands.org/forum/topic/1821/
