Immersed

I really like the new participating media system.  The fixed math works wonders!  Here's the classic test scene immersed in a cylinder of gas:

I really love how much that lower light propagates through the gas - this is exactly the effect that I want the ship's mining beam to have in my render.  I want the surrounding gas to be brightly-lit and saturated with color.  Looks like this system will be perfect for just that!
