Edges billboard trees

#1 2 things:

1. If you want a "blurry" edge on your transparencies you might have to write/draw it into the alpha channel and then expose it with the "alpharef".

2, Also, I've noticed that if you fog anything on the ground, it gets an overall "fog coloured" edging, like a cartoon lambert shader. Increasing the skybox fogBandHeight might help this.

#2 Thanks Steve, I will give it a try. I just find it strange that the trees has blurry edges in TGEA and not in T3D. Without fog it looks a little bit better.
