//! Simulation effects, part 2: layer-shattering and surface simulations — CC Ball Action,
//! CC Pixel Polly, CC Scatterize, Card Dance, Shatter (planar pieces in perspective), Caustics,
//! Wave World (stepped 2D wave equation) and Foam (stepped bubble sim).
//!
//! Written from the public descriptions of the effects' behaviour. Pieces are textured convex
//! polygons placed in 3D and drawn through a per-piece inverse homography, far to near.
