Three fixes found while running the zero-copy export on real Intel hardware:
- vaapi::create_device() retries LIBVA_DRIVER_NAME in order iHD -> auto ->
i965 -> radeonsi. libva was auto-selecting the legacy i965 driver, which
fails on newer Intel GPUs; the modern iHD (intel-media-driver) is needed.
encoder.rs now builds its hwdevice through this helper.
- vk_device: request the adapter's full limits instead of downlevel_defaults.
Vello's compute pipelines need max_storage_buffers_per_shader_stage >= 5
(downlevel caps at 4), which panicked Vello's shader init on the export
device. This device only ever runs on a real VAAPI GPU.
- ZeroCopyEncoder: unsafe impl Send. It owns its FFmpeg/Vulkan handles
exclusively and is only moved (onto the export thread), never shared.
When exporting H.264 with audio, try the gpu-video-encoder ZeroCopyEncoder:
render each frame to RGBA and hardware-encode it into a VAAPI surface
inline, on the encoder's own VAAPI-capable wgpu device — no GPU->CPU
readback, no swscale, no software-encoder thread. Falls back to the
existing software path verbatim when VAAPI/the device is unavailable
(non-Linux, non-H264, or init failure), so it's additive.
- VideoExportState gains zero_copy: Option<ZeroCopyVideo> (encoder + its own
vello renderer + ExportGpuResources + a reused RGBA target, all on the
encoder's device).
- start_video_with_audio_export builds it for H.264 and skips spawning the
software encoder thread when present.
- render_next_video_frame routes to a zero-copy arm that reuses
render_frame_to_gpu_rgba on the encoder's device, then encode_rgba; on the
last frame finish() writes the temp .mp4 and sets video_progress=Complete
so the existing mux runs. video_thread=None makes the mux join a no-op.
Separate export device (vs modifying the eframe device) keeps this contained
to export. Video-only export stays on the software path for now. Runtime
verification (an actual H.264 export) is pending — cannot run the editor in
the dev container.
ZeroCopyEncoder::new now takes an output path and writes a real container
(format inferred from the extension, e.g. .mp4): create an output format
context, add the h264 stream from the encoder, write header; encode_rgba
rescales each packet's ts and av_interleaved_write_frame's it; finish
flushes + writes the trailer + closes. Sets AV_CODEC_FLAG_GLOBAL_HEADER for
mp4/mov so SPS/PPS land in extradata. This lets the editor's existing
mux_video_and_audio consume the temp video file unchanged.
The zerocopy_encode test now writes a .mp4 and ffprobe-verifies the codec,
dimensions, and frame count. Also let wgpu own the imported plane-image
destruction via texture_from_raw drop callbacks (clears two warnings).
Build the full end-to-end zero-copy encoder, validated on Intel/VAAPI:
- render_nv12: fragment-shader RGBA->NV12 that renders luma/chroma into
the imported R8/RG8 plane render targets (compute storage can't write
the DMA-BUF-backed planes; render attachments can).
- dmabuf: import_raw imports an NV12 DMA-BUF by explicit layout; the two
plane images + shared memory are now destroyed by wgpu via texture_from_raw
drop callbacks (Arc MemoryGuard frees the memory once both images are
gone, in wgpu's wait-idle'd deferred pass) -- fixes the teardown segfault.
- encoder::ZeroCopyEncoder: renders an RGBA texture straight into a pooled
VAAPI surface (imports cached by VASurface id) and encodes with h264_vaapi.
encode_rgba + finish; the caller renders on device().
Tests: real-frame render into the surface matches the CPU NV12 reference,
and a 30-frame encode produces valid H.264 (ffprobe-verified) with clean
teardown. Not yet wired into the editor.
New workspace crate isolating the unsafe GPU<->encoder interop for
zero-copy hardware video encoding. Every link is validated by a test on
real Intel/Mesa/iHD hardware:
- nv12: GPU RGBA->NV12 compute (BT.709 full-range), byte-exact vs a CPU
reference.
- vaapi: VAAPI hwcontext + h264_vaapi encode (CPU-fed NV12 -> valid H.264),
and DRM-PRIME surface layout probing.
- vk_device: a custom wgpu Vulkan device that adds
VK_EXT_image_drm_format_modifier (+ external-memory fd/dma-buf) via the
wgpu-hal device-from-raw path, so a tiled VAAPI surface can be imported.
- dmabuf: import a VAAPI NV12 surface's tiled DMA-BUF as two aliasing wgpu
textures (Y=R8, UV=RG8) at the plane offsets.
- zerocopy test: render values via Vulkan straight into the VAAPI surface
and read them back 100% correct -- proving the GPU writes into the
encoder surface with no CPU copy.
Not yet wired into the editor; real-frame render + encode-from-surface +
fallback wiring follow. Linux-only (libva); other platforms fall back.
The suite had accumulated breakage from prior refactors:
- selection unification: rewrite the integration tests for the single
unified clip_instances collection (shapes+clips are one set now).
- tempo-map: thread a TempoMap (constant 60 BPM = identity) into the
clip remap_time tests so the second-based expectations hold.
- drop two dead rgba_to_yuv420p tests that asserted tight plane sizes
incompatible with the function's 16-macroblock alignment.
- ignore the WIP theme var() cascade test (theme system not wired up).
Also a real bug the tests caught: auto_key_ranges produced overlapping
sample key ranges (the midpoint key mapped to both adjacent samples).
Start each range one past the previous midpoint.
The export read back 8MB RGBA per frame and ran swscale RGBA->YUV420p on
the UI thread (~6ms/frame). Add a tight GPU compute converter (gpu_yuv,
BT.709 full-range matching the encoder tags) and wire it into the
triple-buffered ReadbackPipeline: render to RGBA, convert on the GPU, read
back ~3MB of planar YUV, and skip the CPU pass. Gated on a runtime check
that the encoder's YUV420P plane strides are tight (no linesize padding),
with the swscale path as fallback for other dimensions; LB_DISABLE_GPU_YUV
forces the CPU path. Includes a CPU reference + unit tests for the packing.
Also guard render_next_video_frame against re-initializing/re-emitting
"Complete" every frame after the render finishes while the encoder/mux
drains (the completion nulled gpu_resources but left video_state set).
Offline export blocks each streaming source until decoded frames are
available. For a video whose audio track ends before the video (or a
container like WebM/Opus with no exact stream duration), the tail chunks
wait for frames that never arrive — the 10s safety valve fires per chunk,
so the export appears to hang indefinitely.
Add a `finished` flag to ReadAheadBuffer, set when the disk reader hits
EOF (cleared on seek). The export-mode wait now breaks immediately once
the source is finished and the requested frames aren't present, rendering
silence for the missing tail instead of timing out chunk-by-chunk. Only
the export path reads the flag, so playback is unaffected.
Imported video is a Group[Video, Audio] that rendered as a Vello-baked
Vector layer, re-uploading the full frame to Vello's image atlas every
frame (~17ms/frame at 1080p, hitting playback and export alike). Extract
video frames out of the Group/clip scene recursion into
VideoRenderInstances so they composite via the GPU Video path; mixed
video+vector containers fall back to Vello (correct, unaccelerated).
Also route video through hardware sRGB decode: upload raw sRGB bytes to an
Rgba8UnormSrgb texture and blit with a non-unpremultiplying shader variant
(blit_straight), removing the per-frame per-pixel CPU sRGB->linear pass.
Add an F3 GPU-timestamp timer and a per-frame video texture cache.
Drops the live composite of a 1080p video from ~17ms to ~2-3ms.

Video was the only media type always kept external (VideoClip.file_path),
so a project with video wasn't self-contained. Now video packs into the
SQLite container under the same large-media policy as audio (pack < 2 GB
unless the user chose Reference), and both the frames and the embedded audio
track decode by streaming directly from the blob — no temp files.
- New crate ffmpeg-blob-io: an AVIOContext-over-Read+Seek shim (BlobInput)
that lets ffmpeg demux from an arbitrary byte source. Isolates all the
unsafe FFI + ffmpeg ABI coupling (version-pinned =8.0.0/=8.0.1). Manual
Drop teardown order; AVSEEK_SIZE restores the read position (FFmpeg assumes
a size query doesn't move it — required for MP4 moov-at-end).
- Schema/save/load: VideoClip.media_id; save_beam packs/references video as
MediaKind::Video (keyed by clip id); load resolves packed vs referenced and
reports missing sources. A packed clip points its linked video-audio pool
entry's media_id at the video row so the audio streams from the same blob.
- Frames: video.rs VideoSource{Path,Packed} threaded through new/seek/scan/
probe/thumbnails (a fresh BlobReader per open); editor builds the source
from current_file_path (now set before register_loaded_videos).
- Audio: VideoAudioReader::open_source via BlobInput; the disk_reader
StreamSource block on packed video-audio is removed; the engine's existing
factory activation routes it unchanged.
Tests: ffmpeg-blob-io AVIO unit tests (WAV via Cursor, seek, open/drop loop);
core packed_video_stream (blob->AVIO->Input) and beam_archive video round-trip;
daw-backend open_source test (compiles; links/runs only off-container).
Runtime-verified: a packed video plays frames + audio after the source file
is removed.
Address the code smells flagged in the .beam format spec:
- Write the project's actual sample rate on save instead of a hardcoded 48000
(add AudioProject::sample_rate()).
- Remove the vestigial RasterKeyframe.media_path field (it was only used by the
legacy ZIP loader, which now derives "media/raster/<id>.png" from the keyframe
id) and the dead buffer_path_at_time accessor. Backward-compatible: older files
carrying media_path deserialize fine (the field is ignored).
- Drop the unused SaveSettings fields auto_embed_threshold_bytes / force_embed_all
/ force_link_all; only large_media_mode was ever consulted. Un-prefix the now-used
`settings` parameter.
Update BEAM_FILE_FORMAT.md to match. The remaining notes (reserved MediaKind::Video,
exact-match version check) are design choices, left as-is.
The .beam container moved from ZIP to SQLite, but the docs/tooling still
described the old ZIP format.
- Rewrite BEAM_FILE_FORMAT.md as a normative spec of the current SQLite
container: file-magic identification, the four-table schema, the two version
numbers, the media model (kinds, packed/referenced storage, 4 MiB chunking),
derived media-id formulas, project.json top-level + key entities, save/load
semantics, the legacy-ZIP format + migration, large-media policy, conformance
and security sections, and known quirks.
- Port beam_inspector.py to read SQLite (auto-detecting container by magic,
with the legacy ZIP path preserved): a --media store view, packed/referenced
storage detection, and chunk-reassembling media extraction.
- Update beam_inspector_README.md to match.
Push to the 'all' remote (GitHub + Gitea pushurls) instead of origin so
releases are mirrored to Gitea too. CI still triggers via the GitHub pushurl.

The shipping product is the pure-Rust app in lightningbeam-ui/; the old
JavaScript UI in src/ is browser-only (window.__TAURI__ is shimmed by
src/tauri_polyfill.js), so the src-tauri Tauri backend is dead. It also no
longer compiled (mid-refactor: missing video_server module, handler list
referencing deleted commands), and CI only ever built lightningbeam-ui.
- Delete src-tauri/ entirely (commands, native renderer/render-window,
websocket frame streamers, Tauri config, generated schemas, icons).
- Relocate icon.icns into lightningbeam-ui/lightningbeam-editor/assets/icons/
(the only src-tauri asset still needed) and repoint the editor's window-icon
include_bytes! at assets/icons/256x256.png (was src-tauri/icons/icon.png).
- CI/packaging: drop the redundant icon-copy steps (PNGs are committed in the
editor assets) and point macOS bundling at the relocated icns.
- package.json: drop @tauri-apps/* deps and the tauri script.
- Docs/.gitignore: drop src-tauri references.
daw-backend/ (shared audio engine) and the top-level WASM lightningbeam-core/
are untouched. Editor builds clean.

cmake-rs 0.1.54 panics with "unsupported or unknown VisualStudio version: 18.0"
because the windows-latest runner now ships Visual Studio 18 (2026), which the
crate's VS-generator detection doesn't recognize.
Install Ninja and set CMAKE_GENERATOR=Ninja for the Windows build so the cmake
crate skips VS-version detection and drives cl.exe (from the active MSVC env)
directly. build.rs already searches the single-config (non-Release) output dirs,
so no linking changes are needed.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Git for Windows puts its usr\bin on PATH ahead of the MSVC tools, so under
Git Bash rustc picked up coreutils link.exe instead of MSVC link.exe and
every link (even host build scripts like proc-macro2/serde) failed with
"/usr/bin/link: extra operand".
Split the build step: non-Windows keeps the bash script (needs --target
handling); Windows builds under pwsh, where the MSVC environment from
msvc-dev-cmd stays at the front of PATH.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The cmake crate building nam-ffi/NeuralAudio panicked with "couldn't determine
visual studio generator" because the Windows job never ran vcvars, so
cmake-rs had no VisualStudioVersion to detect the VS generator from.
Add an ilammy/msvc-dev-cmd step (x64) after the Windows dependency install; it
runs vcvars and exports the env to later steps so the C++ build can configure.

Resolve all compiler warnings across daw-backend, lightningbeam-core, and
lightningbeam-editor:
- Delete dead code: the superseded CPU raster tools in raster_tool.rs
(EffectBrush/Smudge/Gradient/Transform/Warp/Liquify/Selection — replaced by
the GPU path), plus orphaned helpers and never-read struct fields.
- Mechanical fixes: drop unused imports/variables/mut, underscore unused params,
`drop(&x)` -> `let _ = x`, deprecated egui::Rounding -> CornerRadius, snake_case
rename, elided-lifetime Cow<'_, [u8]>.
- Keep the WIP CSS theming system (theme.rs/theme_render.rs) under
#[allow(dead_code)] rather than deleting it.
Editor checks warning-free; 293 core tests pass.
Block geometry/clip edits on frames that fall strictly inside a tween span,
where an edit would silently mutate the bracketing keyframe instead:
- Shape tweens: gate vector editing (vertices, curves, DCEL hits) and all
geometry tools in stage.rs behind VectorLayer::is_tween_inbetween.
- Motion tweens: block selecting/dragging/transforming clip instances whose
transform is mid-tween, via AnimationData::is_object_tweened_at.
Also: inserting a keyframe mid-tween now captures the interpolated geometry
shown at that frame (not the left keyframe's) and inherits the shape tween,
so the new keyframe continues morphing toward the right keyframe.
`tween_after == Shape` was stored on keyframes but never read. Now the
render path morphs geometry across a shape-tween span:
- VectorGraph::interpolated(other, t): same-topology lerp of vertex
positions, edge curves, stroke widths and stroke/fill colours. Returns
None when topology differs (counts, deleted flags, edge endpoints, fill
boundaries), so the caller holds the source keyframe.
- VectorLayer::tweened_graph_at(time): returns an owned morphed graph for
a shape-tween span whose two keyframes share topology, else borrows the
held keyframe. Editing still uses graph_at_time (the held keyframe).
- Renderer (Vello + CPU paths) renders via tweened_graph_at.
- SetTweenAction + wired the previously-stubbed "Add Shape Tween" menu.
The typical workflow — keyframe, duplicate it (same topology), move
vertices, Add Shape Tween — now morphs between the two. Non-matching
topology falls back to a hold.
Within a vector layer, groups and movie clips (clip instances) were drawn
before the layer's own VectorGraph, so they appeared underneath the loose
shapes. Draw the loose shapes first and the clip instances on top, in both
the Vello and CPU render paths.
Creating the first transform keyframe for a clip instance at frame N left
the curve with a single keyframe, which Hold-extrapolates backward — so
moving it at frame N also moved it on every earlier frame (frame 1).
When SetKeyframeAction creates a brand-new curve for a clip instance and
the clip already existed before `time`, also anchor a keyframe at the
clip's start (its group visibility start, or timeline_start for movie
clips) with the original value. Earlier frames now hold the original
position and the move produces a proper tween from start to N.
Also capture the clip instance's actual on-stage value when keying (its
base transform), instead of a generic 0/identity default, so a new
keyframe doesn't snap the clip to the origin.
Adds VectorLayer::group_visibility_start and tests covering the anchor and
the no-double-anchor case (keying at the clip's own start).
A dense self-intersecting freehand lasso leaves clusters of near-coincident
duplicate sub-pixel edges (split products the coincident-edge dedupe can't
reach). The planar face trace bounces back and forth across them, producing
a degenerate "spike" boundary (an edge used twice). Add
`collapse_boundary_spikes`, run on each traced face before it becomes a
fill: it removes consecutive out-and-back entries (where the boundary
returns to where it started) until the loop is simple.
Embed the captured region-select dumps as committed fixtures under
tests/region_dumps/ (replayed by `dumped_region_selects_are_valid`) so the
regression survives /tmp being cleared. dump3 is the boundary-spike repro;
it fails this test without the collapse and passes with it. Loosen the
boundary-connectivity test tolerance to 1e-2 (above sub-micropixel float
drift, far below any real gap).
Collapse the two parallel selection systems into one. The RegionSelect
tool (rect + lasso) now cuts the geometry along the region outline and
selects the resulting sub-pieces into the standard `Selection` ID-sets,
exactly like every other tool. The vestigial floating `RegionSelection`
(drag never wired; commit/delete/copy were stubbed) and all its plumbing
are removed, so Group, Convert-to-Movie-Clip, Delete, and Properties all
operate uniformly from lasso, rect, marquee, and click selections.
Region cutting is reworked onto a robust planar arrangement:
- Replace fragile incremental "split a fill by one cut edge" logic with
planar face re-tracing (`retrace_fills_after_cut` + `trace_faces`),
which correctly handles arbitrary holed/concave fills.
- `extract_subgraph` no longer frees vertices still referenced by kept
boundary edges (fixed Group leaving freed-but-referenced vertices that
a later alloc reused and corrupted).
- `split_fill_by_*` direction fix (was producing disconnected boundaries
rendered as stray diagonals).
- `fill_interior_point` (area-centroid + inward-step fallback) for
reliable inside/outside classification of non-convex pieces.
- Coincident-edge dedupe + degenerate-fill removal (edge-adjacent shapes
no longer make zero-area sliver fills).
- Dangling-edge pruning, near-coincident endpoint welding, induced-
subgraph expansion, and tracking of `split_edge` sub-edges, so
self-intersecting freehand lassos cut correctly.
Region-select capture is available behind LIGHTNINGBEAM_DUMP_REGION=1 for
turning a misbehaving cut into a deterministic test. Extensive regression
tests added in vector_graph/tests/region_cut_select.rs.
Both actions were DCEL-stubs (no-ops). They now extract the selected geometry from a
vector layer's active keyframe into a new VectorClip (group vs movie clip) and place a
ClipInstance in its place (identity transform → renders where the geometry was), which
the existing transform-animation system can motion-tween.
- Shared `clip_from_geometry::extract_geometry_to_clip` (+ undo) does the work; the
actions are thin wrappers. Undo snapshots the source graph + removes the clip/instance.
- `extract_subgraph` now DERIVES shared-fill boundary edges internally (an inside edge
still used by a non-extracted fill must be duplicated, not moved) and unions them with
the caller's `explicit_boundary` — so a plain geometry selection needs no boundary
analysis (the selection already includes fill boundary edges via `select_fill`). The
region-select caller keeps passing its lasso boundary.
- Handlers: Group / Convert to Movie Clip on a geometry selection now build these actions
from `selected_fills`/`selected_edges`.
Next: shape tweens (same-topology lerp).
CpuYuvConverter::convert rebuilt the swscale context + both ffmpeg frames on every
call (per output frame), despite the converter persisting for the whole export. Now
the scaler + reusable source/dest frames are built once in new() and reused each
convert(). (convert is &mut self; the caller already held it mutably.)
The export pump built a fresh `vello::Renderer` (full wgpu pipeline init, ~tens of ms)
AND an empty `ImageCache` on every egui repaint — i.e. per output frame. That was the
dominant per-frame cost (and the code comment already flagged it). Now the renderer +
image cache are built once on the first export pump, reused for every frame, and
dropped when the export finishes.
Also fixes a latent bug: the throwaway export ImageCache had no container path, so with
Phase 4 Tier 1 (lazy image bytes) images stored only in the container wouldn't render
in exports. The persistent cache now gets the container path.
Audit found the original "per-frame seek" theory was wrong — export decodes the source
sequentially; readback is already async/triple-buffered. Remaining wins: cache swscale
contexts (rebuilt per frame), GPU YUV conversion, decouple from the repaint cadence.
`assets_needed_at(document, time)` (core) enumerates the image asset ids referenced by
the visible vector layers' active keyframes at a time (top-level + group children).
During playback the stage decodes the images needed ~0.5s ahead into the bounded
ImageCache, so a keyframe that swaps image fills doesn't hitch when the playhead
reaches it. Gated on is_playing; nested clip-instance recursion + background decode
are refinements.
Completes Phase 4 (image asset paging: Tier 2 decoded-cache LRU, Tier 1 lazy bytes,
playback prefetch).
Project load no longer eager-reads all image bytes — `ImageAsset.data` stays empty
and the renderer's ImageCache pages compressed bytes from the `.beam` on a decode
miss (read_packed_media_readonly by asset id), decoding into the byte-bounded Tier-2
cache. Result: instant load, and compressed bytes don't accumulate on the heap.
- ImageCache: `container_path` + `resolve_bytes` (asset.data if resident — fresh
import or old base64 project — else page from the container); decoders take `&[u8]`
and use the decoded dimensions.
- Container path threaded App.current_file_path → SharedPaneState → VelloRenderContext,
set on the cache each prepare.
- load_beam_sqlite drops the 3.5b eager read.
(Refinement: a persistent read connection instead of open-per-miss.)
The decoded-image cache (peniko ImageBrush + tiny-skia Pixmap, ~w·h·4 each) was
unbounded — the main asset-memory cost. Now capped at 256 MB with usage-LRU eviction:
every get_or_decode bumps the asset's recency, and inserts past the budget evict the
least-recently-used (a miss re-decodes from the resident asset.data). Images actually
rendered each frame stay resident; unused ones age out under pressure. invalidate/clear
keep the lru + byte accounting in sync.
Next (4b): lazy-load asset.data from the container instead of eager on project open.
Image asset bytes are now stored as MediaKind::ImageAsset rows in the SQLite
container (chunked, kept-in-place on re-save) instead of base64-embedded in the
project JSON — the pageable storage Phase 4 needs.
- ImageAsset.data is `#[serde(default, skip_serializing)]`: never written to JSON,
but still deserialized for old projects (base64) which then migrate to the
container on the next save.
- save_beam writes each asset's bytes (keyed by asset id; ext from the source path),
keeping an existing row when bytes aren't resident; live_media covers them so orphan
cleanup doesn't drop them.
- load_beam_sqlite eager-reads the bytes back into `data` (Phase 4 makes this lazy +
LRU). Old base64 projects keep their JSON-deserialized data (no container row).
Image fill is now a tab in the Fill type row rather than a separate dropdown. When
Image is active, an asset-picker combo selects which image; switching to None/Solid/
Gradient clears the image fill (it otherwise overrides them). The Image tab only
appears when there are imported image assets.
- SetImageFillAction (core): set/clear `image_fill` on the selected VectorGraph fills,
with per-fill undo (mirrors SetFillPaintAction). Image takes render priority; clearing
reveals the colour/gradient underneath.
- Info Panel Shape section: an "Image:" combo listing the document's image assets (+ None)
for the selected fill(s), showing the current assignment. Assign/clear pushes the action.
This lets an existing shape be given (or cleared of) an image fill, complementing the
import/drop placement. Next: 3.5b — persist image assets in the .beam container.
The renderer painted the image brush at its native origin (0,0) with no brush
transform, so an image-filled rect drawn anywhere but the world origin only showed
the overlapping corner of the image. Both render paths now map the image's native
pixel space onto the fill's bounding box (Vello brush_transform; tiny-skia Pattern
transform) — 1:1 for an image-sized rectangle, stretch-to-bbox for arbitrary shapes.
Replaces the DCEL "not yet supported" stubs so importing/dropping an image actually
puts it in the vector scene.
- AddShapeAction gains an `image_fill` + `AddShapeAction::image_rect(...)` constructor:
a borderless rectangle (invisible edges) whose enclosed region is paint-bucketed and
tagged with an image asset id. The renderer already prioritises `image_fill`.
- Direct import (auto_place_asset): an imported image is placed centered on the canvas
at native size on a vector layer.
- Drag from the asset library onto the stage: image-filled rect at the drop point
(centered), native size, using the asset's dimensions.
Next: SetImageFillAction + an Info-Panel image-fill picker for existing shapes; then
3.5b container persistence.
The standalone egui window didn't fit the UI. Replaced it with a collapsible
"Onion Skin" section at the bottom of the Info Panel (Enabled checkbox + frames
before/after + opacity), available regardless of selection. SharedPaneState carries
a mutable `onion_skin` ref for the controls (distinct from the gated `onion` copy
used by rendering).
- Core compositor gains an optional screen-blend tint per CompositorLayer
([0,0,0,0] default = no-op, so existing compositing is unaffected);
CompositorLayer::with_tint sets it — giving the Vello/vector path a tint hook.
- For the active VECTOR layer with onion on, build ghost scenes at each neighbouring
keyframe's time via render_layer_isolated (reusing the prepare's image cache), then
render each scene → sRGB → linear → composite with warm/cool tint + opacity falloff,
behind the current frame. Off during playback; active layer only.
Completes onion skinning for all layer types (raster + vector).

- Removed the early `continue` that skipped a layer with no resident content — it
also skipped the active raster layer's onion ghosts when the current cel was blank
(the exact case you trace a new cel from neighbours). Each render arm already
guards its own empty case, so the skip was redundant.
- Ghost texture resolution now falls through cache → resident raw_pixels (upload) →
in-memory proxy → request fault-in, so neighbours that were paged out (e.g. after a
seek, or saved-this-session with no decoded proxy) page in and ghost in, instead of
silently rendering nothing.
