- GPU Pixel Motion Blur (#695) declined without a host; it now averages the shutter's
frames like the CPU effect (tests_fx_time::without_a_host).
- add_item_keeps_footage_longer_than_the_comp_at_full_length (#798) built footage with
the default kind (Still), which adds at comp length; it is a movie.
- docs/effects.md regenerated.

Cause: Apply Color LUT's only parameter, `lut`, was ParamUi::Hidden (set only
through commands), so the effect could not be used from the UI. Effect
Controls also had no widget for any ParamUi::Text parameter (only EXtractoR's
channels had one), so Cryptomatte's Selection, the OCIO effects' config file /
file / config names and Colorama's Output Cycle could not be set either.
Fix: a new ParamUi::File { filters } for paths. Effect Controls shows the
file's name (None when empty) and a Choose... button that opens the host's
file dialog with those extensions and sets the path (prop.set, so agents use
the same command). As in After Effects, applying an effect with an empty file
parameter from the UI (Effect menu, Last Effect, drops, Effects & Presets)
opens the file dialog straight away; cancelling keeps the effect without a
file. Apply Color LUT's LUT (.cube) and the OCIO Config File (.ocio) and File
(.cube/.3dl/.csp/.cc/.ccc/.cdl/.spi1d/.spi3d/.spimtx) use it. Text
parameters get a single-line field that sets the value when it loses the
focus (Esc keeps the old text). Saved projects are upgraded on open: a
Hidden or Text parameter whose spec is now a File parameter takes the File
UI and keeps its path (effects::migrate). docs/effects.md regenerated.
This covers #473's first part (the Selection field); picking mattes in the
viewer, the layer popup from the file's metadata, the GPU path and quoted
commas are separate.
Tests: effects hidden_and_text_paths_become_file_parameters (migration); ui
file_and_text_parameters_have_widgets (the LUT is asked for on apply and
inverts red to cyan, the Choose... button picks another LUT, typing into
Cryptomatte's Selection sets it).

(cherry picked from commit 403863f703999d19d3a83d9976f76bdc7577e682)
Cause: CC Particle World projected its particles through a fixed camera
(distance 2 layer widths, looking at the layer centre) and never asked the
host for the comp camera, so moving or orbiting a camera layer left the
particles flat on the layer. It also had no Extras > Effect Camera. Separately,
the layer cache key ignored the comp camera and lights, so the effects that
read them (Card Dance / Shatter / Card Wipe Comp Camera, First Comp Light,
Caustics) kept a stale frame when the camera, a light or the layer moved.
Fix: as the Cycore manual describes, Particle World sees its particles through
the comp's active camera layer when there is one (EffectHost::comp_scene now
says whether its camera is a camera layer's, CompScene::camera_layer), through
card3d's comp-camera projection (factored out of Card Dance as comp_proj, with
Proj::view for depth, size scale and screen velocity). Otherwise it uses the
new Extras > Effect Camera: Distance (2), Rotation X / Y / Z (0) and FOV (50)
orbit the world origin; FOV moves the camera so the origin's plane keeps the
scale Distance gives it, so the defaults reproduce the old fixed camera bit for
bit (golden hashes unchanged) and old projects render as before. The Effect
Camera is left out of the simulation cache key, so animating it doesn't
restart the simulation. The plan is shared, so the GPU compositor follows too.
The layer cache folds the comp scene into the key of layers running an effect
in effects::READS_COMP_SCENE (render::comp_scene is shared with the host).
Tests: sim particle_world_follows_the_comp_camera (panning a camera layer moves
the particles, zooming spreads them, the Effect Camera is ignored then, the
default view keeps the Effect Camera, cameras facing away / zero / NaN draw
nothing) and particle_world_effect_camera (missing params = defaults, rotation,
distance and FOV change the view, extremes stay finite, the sim key ignores the
camera); render particle_world_follows_the_comp_camera (a real camera layer
panned 40 px moves the particles left, and the cached render after the move
equals an uncached one: it failed with the old cache key); gpu
particle_world_through_the_comp_camera (CPU vs GPU at 8 / 32 bpc, full and
half resolution). particle_golden / sim_golden unchanged. effects.md
regenerated; parity.md and gaps.md describe the fix.

The geometry stays on the CPU as per-frame plans shared with the CPU effects (bolts, mask
strokes, scribbles, contour segments, audio marks, glyph strokes, waves, flood-fill region,
eyedropper sample); segments and convex polygons are tile-binned and rasterised on the GPU
with the CPU's coverage functions. CPU output unchanged (gen_golden). CC Threads' exact ties
at round parameter values are a documented exception; Fractal stays on the CPU (needs f64).
Regenerated docs/effects.md, docs/parity.md EFF-5.

GPU render passes for CC Particle World / Systems II, Particle Playground,
CC Ball Action, CC Pixel Polly, CC Scatterize and Curl Noise (fx_particles,
chunked multi-pass raster); Shatter wireframe views, Foam extras, Timewarp
with a Matte Layer, strong Warp Fisheye/Twist (CPU f64 inverse map) and
custom .ocio configs no longer fall back to the CPU. CPU refactors pinned by
particle_golden / timewarp_golden / sim_golden hashes.

Inner/Outer Key's trimap and Cleanup strokes, Color Link's sample and CC Glass/Plastic's
light are shared with the CPU effects (CPU output unchanged: gen_golden). CC Plastic now
reads its Bump Layer (it read the nonexistent bumpMap id).

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.

Timewarp without a Matte Layer is now planned once (time_fx::timewarp_plan: frames, shutter
instants, motion fields) and built by the CPU or the GPU from the plan; with a Matte Layer it
renders on the CPU (catalog::gpu_supported).

VR Blur, Chromatic Aberrations, Color Gradients, Converter (all projections and
cube layouts), De-Noise, Digital Glitch, Fractal Noise, Glow, Plane to Sphere,
Rotate Sphere, Sharpen and Sphere to Plane run on the GPU (fx_vr.rs /
fx_vr.wgsl) with the CPU's equirectangular maths: seam-wrapping, pole-continuing
sampling and latitude-widened box blurs, per eye for stereo layouts.

CC Environment now fades nearly transparent environment texels to black continuously
(colour / max(alpha, 1e-3)) instead of a hard 1e-6 un-premultiply cut-off, which turned the
filtered map's float noise into colour.

Apply Color LUT, OCIO CDL / Color Space / Display / File / Look Transform and
Color Profile Converter compile to colour programs (effects::color_program,
built next to the CPU effects) that fx_lut.wgsl interprets per pixel; LUTs
(1D, 3D, cineSpace shapers, inverses) are read from the storage buffer with the
CPU's nearest / trilinear / tetrahedral interpolation. Lumetri's Input LUT and
Look no longer force the CPU. Custom .ocio configs stay on the CPU.

3D Channel Extract, Cryptomatte, Depth Matte, Depth of Field, EXtractoR, Fog 3D,
ID Matte and IDentifier run on the GPU (fx_depth.rs / fx_depth.wgsl): aux planes
upload as a texture and are resampled onto the buffer grid with the CPU's index
arithmetic; tests compare against the CPU at 1x / 2x aux resolution, padded
buffers, half resolution and 8 / 32 bpc composites.

- Transform: Use Composition's Shutter Angle / Shutter Angle, sampling the transform across
the shutter via EffectHost::params_at (EffectEnv::shutter carries the comp shutter when
motion blur is on); the GPU path defers to the CPU when blurring.

fx_color kernels mirror the CPU effects operation for operation: one per-pixel
pass for the point effects, Lumetri with its Sharpen luminance blur, and Key
Light's matte pipeline (pre-blur, clip, rollback, despot, shrink/grow, softness,
edge band) as plane passes. CPU fallback: Key Light with Inside/Outside masks or
Hard Colour after Screen Softness, Colorama with Interpolate Palette off.

Kernels in fx_generate.wgsl mirror the CPU effects; wipe edges use f64
per-column/per-row terms uploaded as (hi, lo) pairs. CPU helpers shared
with the GPU are now public (camera_lens_spans, gen_mode, pattern_kind,
GrainLook, place_layer). GPU tests in tests_fx_generate.rs.
