Moved transient states (current vertex buffer etc) to controller. ComputeContext becomes constant so that it's well suited for coarse-grain parallelism on cpu. The prims sharing same topology (ComputeContext) can be refined simultaneously by having mutiple compute controllers. Client facing API doesn't change.
