Frame drop shadows re-render every child silhouette inside a single
walker node, so the usual partial drain cadence (every N tree nodes)
lets GPU ops pile up. Flush every few shadow passes instead.
Store encoded media in RAM, upload a shape-sized display texture
eagerly, and only promote the native full texture when zoom needs
it so oversized fillImages do not saturate integrated GPUs.
Present visible tiles via ViewportReady so zoom settle turns sharp
without waiting on the interest ring, and paint at atlas slot size so
DPR 2 does not rasterize 1024 only to downscale into 512 slots.
Keep the shape-to-tile grid zoom-only while scaling GPU paint by DPR
(capped at 1024px). Fix fractional browser zoom and pan, cap atlas slots
with eviction instead of panic, and split paint vs view scale with
explicit paint/atlas/screen tile sizes.
Release packs far more cheap Current draws (e.g. fills_none paths)
into one Partial than debug; a single end-of-Partial
flush_and_submit then stalls the browser. Soft-flush every N walker
nodes (and on Partial yield) keeps ops buffers bounded while Full
still submits via present_frame.
* ⚡ Skip drop shadows that are imperceptible at current scale
Filter drop shadows by on-screen footprint (stricter for recursive
shapes) so overview HQ avoids expensive blur passes that barely show.
* ⚡ Simplify Path and Bool strokes at low scale
At overview zooms, Inner/Outer strokes fall back to Center and
dash/dotted styles become solid when the pattern is subpixel.
Strokes are never skipped so stroke-only icons stay visible.
* ⚡ Drain GPU work on partial render frames
Partial frames only flushed the Backbuffer, so tile GPU commands
queued until present_frame's flush_and_submit and stalled the
browser on large files. Submit the context each partial frame
without presenting Target or re-composing the tile atlas.
* ⚡ Prefer direct painting when effects are imperceptible
Skip the Fills/Strokes layered path when drop/inner shadows would
not paint at the current scale, and allow stroke-only shapes
(fills_none) on the direct path. Apply the same footprint LOD to
inner-shadow painting.
* ♻️ Extract apply_clip_stack_to_surfaces helper
Share the layered-path clip loop so the Current-surface direct
path can reuse the same hard-clip stack without duplication.
* ⚡ Expand direct shape painting onto Current
Allow clip stacks, frames, non-identity transforms, and SrcOver
opacity on the Current-surface fast path; skip empty non-masked
groups. Avoids Fills/Strokes blits for common shapes.
* ⚡ Skip empty drop-shadow blits; warm DropShadows once
Early-out drop-shadow composite when a shape has no visible
shadows, and touch DropShadows→Current once per tile instead
of per shape to keep flush_and_submit cheap.
Pass performance.now from finalize/debounce and re-anchor the WASM
budget if the stamp is 0 or already past max_blocking_time, so HQ
tiles are not yielded after a few nodes with almost no real work.

Use direct backbuffer tile compositing for render_sync_shape (viewer/thumbnails)
instead of the tile texture atlas cache, which left 512×512 transparent holes.
