Blender Smoke - Adaptive Domain

Early testing of adaptive domain size feature I'm currently working on.

When it's enabled: smoke domain scales it's resolution and size to only match areas where smoke is. This enables very fast simulations of large smoke areas if only one part of the domain has smoke at a time.

You see two bounding boxes visualizing domain area.
1) The static one is the "normal" domain area, basically it just defines the size and location of the simulation.
2) Then there is that moving area. It's the actual simulated and stored part of the domain, adapting to simulation content.


Note: This is an experimental feature I'm working on as a GSoC 2012 project. Development happens in the "soc-2012-fried_chicken" branch.
