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.
