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.
Avoid an offscreen buffer per Fill::Image during tile walks: only use
save_layer when a shape image filter is present; axis-aligned rects and
frames without corner radii also skip the redundant container clip.
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.
* ✨ Add headless wasm render backend to the exporter
* ♻️ Move render-wasm bridge to common and split wasm builds
* 🔧 Upload builtin font variants in the wasm exporter
* ♻️ Move shared font and resources utils out of render_wasm
* ⚡ Fetch only the exported roots in the wasm exporter
* ⚡ Bound save_layer rects in the vector export path
* ⚡ 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.
Marking intermediate surfaces dirty after clearing them on tile
context switch made the first stack composite blit empty
Fills/Strokes/shadows into Current. Dirty means content to
composite, so clear the flags after the clear instead.
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.
Copy Current into DocAtlas and the tile atlas with Surface::draw
instead of image_snapshot_with_bounds, matching the interactive
path and removing a GPU sync stall on every completed tile.
* 🔧 Support background blur on PDF render for strokes and text shapes
* ✨ Add LRU eviction to the wasm image store
* ✨ Add RasterFormat to encode png, jpeg and webp from wasm
* 🐛 Fix client-side wasm export encoding jpeg and webp as png
* 🐛 Skip identity transforms in layout reflow propagation
Layout reflow emitted identity transforms for unchanged children, which
fanned out through the whole subtree on every drag frame and froze large
files in the WASM renderer.
