Try and avoid re-sorting the children by buckets (if we can!). This makes change in rendering order in the 'Transparency' app actually work.
Internal API change around postprocessing.
Make Postprocessing quality per-effect (rather than applied to the whole queue)
Remove DistortedEffectsPostprocess and unify it with DistortedEffects.
Job not finished - doesn't compile now!
Progress with support for Effect classes.
