/**

 * Class containing the queue of postprocessing effects.

 * <p>

 * This better be separate from the main DistortedEffects class, because we want to be able to apply

 * the same postprocessing effects (i.e. not only the same effects, but the very same instance of this

 * object) to several Children of a Node. Reason for that: if several children have the same Object,

 * it is easy to group them into 'Buckets' where each bucket has the same postprocessing effects and

 * is therefore rendered to the same buffer, which is then postprocessed in one go.

 * <p>

 * The queue holds actual effects to be applied to a given bucket of several (DistortedTexture,MeshObject) combos.
