M13.23: GPU simulation render passes

Browse Source 
CC Rainfall, Snowfall, Star Burst, Bubbles, Drizzle, Hair, Mr. Mercury,
Caustics, Wave World, Foam, Shatter, Card Dance and Card Wipe render on the GPU
(fx_sim.rs / fx_sim.wgsl). The per-frame simulation / layout stays on the CPU
and is shared with the CPU effect through plans (effects::sprite_plan,
piece_plan, bubble_list, mercury_blobs, drizzle_drops, wave_world_plan,
caustics_setup); a tiled item rasteriser composites sprites, bubbles, blob
fields and textured pieces in the CPU's order and shading. Layer-dependent
sprite colours (refracting rain, star-burst and hair roots) are sampled per
pixel; piece plans read the frame back once.

EffectCraft ships 306 effects with 3009 parameters in total, grouped into the same categories as the Effects & Presets panel. Every effect is our own implementation, written from public behaviour descriptions and standard image-processing literature. Parameter names, order, popup options, units, defaults and ranges follow the reference application so that projects, expressions and muscle memory carry over.
- **GPU**: 193 effects also run on the GPU compositor with identical results.
- **GPU**: 206 effects also run on the GPU compositor with identical results.
- **32**: 306 effects process 32-bit float (HDR, overbright) pixels without clamping.
- **Status**: 306 implemented in full, 0 partial (what is missing is listed).
