Dana, do you have a sense of what the stateless approach would be like, both in terms of complexity-to-implement as well as complexity to maintain? I definitely like just folding in "visibility culling" as a postprocess --- there are maintainability wins and also testing wins to be had from such an approach.

If it helps, we have little indication that the time spent in the compositor drawing is a bottleneck. That is to say, an inefficient implementation thats maintainable is vastly preferred to the fastest version.
