More playing with terrain

Dave was experimenting with some techniques for representing the green-zones. Still experimental and not earth shattering (no shadows in this but they do make a difference). The vegetation models we have turn out not to be to scale, that's more work to put right.

The oaks of the region are smaller than those in Europe but the canopy has a lager spread. This makes them appear more lush. Trees in games tend to be *much* larger than life to reduce the object count and fill up screen space. You hardly think about them. But next time you're playing a game with trees in it, stop and look at the size of them. Count them.

Can't help but feel this would be so much better with just a couple more blended texture layers and a few more tool options. But I think we're getting better as we go.
