I'll submit a a separate piglit test to soon to piglit-dev.
Cool. We really should have these extensions. But we also really need some piglit tests to stress this. The intel_setup_image_from_mipmap_tree() code in this series can orphan siblings the moment they're created. intel_finalize_mipmap_tree() can also do so currently. We need to be able to track somehow where the canonical miptree contents are and resolve our work back to it.
