Refraction samples are clamped to the layer rectangle instead of the buffer, so a sample past the layer's edge in a buffer with transparent padding (a half-resolution preview's, a text or shape layer's) repeats the layer's edge pixels rather than reaching the pale colour that stands in for transparent ones. Transparent pixels inside the layer still show it. Same bounds on the GPU path. Re-pins the four half-resolution CC Bubbles golden hashes (aarch64 macOS); the full-resolution ones are unchanged. Adds a CPU test and a GPU-vs-CPU parity test on padded buffers.

//! Simulation effects (particles, physics, liquids): CC Rainfall, CC Snowfall, CC Bubbles,

//! CC Drizzle, CC Star Burst, CC Particle World, CC Particle Systems II and CC Mr. Mercury.

//!
|
|
//! Written from the public descriptions of the effects' behaviour. Weather/bubble/star effects
|
|
//! are closed-form functions of time (every frame independent); particle systems are stepped
|
|
//! from layer time 0 at a fixed rate through [`SimCache`], so any frame can be rendered
|
|
//! directly and equals the frame reached by scrubbing.

//! Shared here (also used by `sim2`): a band-bucketed rasteriser for many small items
|
|
//! ([`raster`]), particle sprites ([`Sprite`]) and transfer-mode compositing ([`combine`]).
