[Feature Request] Directional Terrain

[HydrallUrakan]

On a few cases I've wanted difficult terrain to only apply in one direction - namely a literal uphill battle where it took double movement to go one direction, or a separate battle where the water had a current that made one direction even worse difficult terrain. Not entirely sure how best it could be implemented, though. There's a lot of angles at which one can enter a tile.

Perhaps slightly further than that, the ideal would be somehow setting things up so, like... This image would be plausible.

Yes, would "slope" difficult terrain would be great! Maybe could add some metadata as to the directions in which it applies.
