Emit polygon path

For 2D pathfinding, the current Path type works fine, but if you want to do 3D pathfinding (with multiple overlapping floors etc.), the current interface is insufficient. In particular, I'm imagining that you project out the X and Y positions of each point in a mesh, which may result in duplicate points. Polyanya supports duplicate points and overlapping/zero-area triangles, at least from my experimentation, but since it only outputs a list of positions it's impossible to know which of many overlapping triangles a given element in a path is from (and therefore what its Z position is). If the indices of polygons traversed were included in the Path then this wouldn't be an issue.

Hmm, looks like I was mistaken and Polyanya only supports duplicate points and zero-area triangles, but not overlapping triangles.
