Clipped frames (show-content=false) were applying clipPath to the drop
silhouette. Spread/offset fills were outset correctly but then truncated
to the true selrect, so spread rings vanished on export. Match the GPU:
paint drop silhouettes outside the content clip; keep clipping on the
real content pass only.
Closes#11653
SkSVGDevice drops save_layer composition for text strokes, so emit
center strokes (with <g opacity> when alpha), inner strokes via glyph
clipPath, and outer strokes via inverse-glyph luminance mask.
Closes#11386
* 🐛 Fix stroke to path dropping caps and markers
Caps and markers (round ends, arrows, square/diamond/circle markers) are
painted separately by `handle_stroke_caps` after the stroke itself, so
`stroke_to_path` — which only outlines the shape path — dropped them.
Converting a stroke to a path lost every end decoration except the
Round/Round and Square/Square pairs Skia draws natively, and even those
were missing because the outline paint kept the default butt cap.
Cap geometry now lives in `shapes/stroke_paths.rs` as plain path
builders, shared by the canvas renderer and by `stroke_to_path`, which
unions the caps into the outline for open paths and honors
`to_skia_linecap`. The SVG export no longer overlays the caps a second
time on top of the expanded outline, which would double the alpha of
translucent strokes; the clip silhouette for image strokes gets them
from the outline too.

AA clip on the Current→atlas blit softens shared tile edges so
the canvas background shows through as 1px lines at the 512px
grid when tiles are composed with SrcOver.
Closes#11638
Cached Skia paragraphs bake absolute image/gradient shaders at layout
time. On move, clones reuse those paragraphs while painting at the new
selrect, so glyphs move and the fill stays put. Record the paint origin
when layout is built and translate the canvas when painting from cache
so shaders track the text. Also sync bounds before update_layout so
fills bake against the current container.
SkSVGDevice drops paint image-filters, so re-emit visible layer blur as a
native feGaussianBlur filter on the composite <g>. Match canvas sigma via
radius_to_sigma(value * scale), and skip Skia blur filters on the SVG
VectorRenderer path so shapes do not vanish.
Closes#11380
Closes#11384
Skia's SVG backend drops save_layer+SrcIn, so image strokes are re-emitted
as a linked <image> clipped to an opaque stroke silhouette (filled outline,
clip-rule evenodd). Open-path caps join the silhouette and grow the image
dest by cap_bounds_margin so markers stay textured.
* 🎉 Implement independent image bounds resizing
Add canvas resize interaction mode that allows users to resize an
image object's bounding box independently from the underlying bitmap
content without scaling or distortion while holding the Mod key.

Emit clipped `<image href>` for fills with a registered media URL instead
of Skia base64 embeds. Register URLs from the frontend and exporter via
store_image_url. Cover rect, path, frame, and text (glyph clip) cases in
SVG export tests.
Closes#11383
* ✨ Export solid inner and outer strokes to WASM SVG
SkSVGDevice drops save_layer+Clear used for path Outer strokes, so
solid Inner/Outer strokes on closed shapes are expanded to filled
outlines via stroke_to_path. Center and open paths stay on the shared
stroke path.
Closes#11381
* ✨ Export dotted, dashed, and mixed strokes to WASM SVG
PathEffects do not survive SkSVGDevice, so dotted/dashed/mixed strokes
expand via stroke_to_path with the effect kept, producing filled
outline geometry for all alignments including Center.
Closes#11382
* 🐛 Fix WASM SVG stroke export edge cases
Keep expanded stroke outlines in local space under the leaf CTM so
rotated rects/paths are not double-transformed; overlay open-path caps
after dotted expansion; draw frame strokes outside the content clip;
and route per-side rect/frame strokes through the evenodd band path.
* 🐛 Align WASM auto-width text size with HTML measurement
Include the HTML paragraph-set 1px right margin in Skia auto-width
so WASM and DOM measurements match.
* ⚡ Scope and defer post-font WASM text relayout
Track pending font faces per shape, force-relayout only affected
texts, defer stale-selrect sync until the first tiles paint, and
batch request-render after attr updates. Tolerate missing font-face
keys so callers that omit them do not blow up.
* ♻️ Share text layout paragraphs across modifier clones
Store Skia paragraphs in Rc so TextContentLayout::clone keeps the
cached layout for rotate/pan modifiers. Add layout.clear() and treat
needs_update as paragraphs-empty only.
* ⚡ Reuse cached Skia paragraphs when painting text
Add try_paint_from_layout_cache to paint from TextContent.layout when
versions match, skipping ParagraphBuilder rebuild and layout on each
frame. Wire into the layered text path for plain fills without strokes
or effects.
* ⚡ Paint plain text directly onto Current
Extend can_render_directly for stroke-free text and skip the empty
save_layer in draw_text when no stroke-group opacity is set. Plain text
paints into Current without the Fills/Strokes blit.
Shapes and text with stacked solid fills were exported without fill
attributes because merge_fills builds a Skia shader that SkSVGDevice
does not serialize. Draw each fill layer separately for SVG export,
bottom to top, matching the classic exporter.
Closes#11466
Upload structural shape attrs (base, children, blur, shadows,
flex, layout-item) via multi-shape `_set_shapes_batch` FFI in
chunks of 512, then apply host attrs with use-shape selection.
* ✨ Add text and @font-face to WASM SVG export
Emit selectable <text> elements and inject @font-face rules that
reference the font URLs registered at load time. Text fill bypasses
save_layer wrappers that SkSVGDevice drops. Text strokes are deferred
to a follow-up PR.
* 🐛 Strip trailing commas from Skia SVG text positions
Skia's SVG backend appends a trailing comma to per-glyph x/y lists.
Firefox rejects the malformed attribute and drops glyph positioning,
making exported text vanish or mis-render.

* 🐛 Fix floating-point equality issues in path editing
Replace exact equality checks with tolerance-based comparisons
in path editing functions to handle floating-point rounding
differences after transforms, rotations, or curve fitting.
Changes:
- distribute-content: Round coordinates to 0.1 precision before
grouping to ensure coincident nodes move together
- separate-node: Use gpt/close? instead of exact equality to
find nodes with floating-point imprecision
- collision-step: Use mth/close? for tolerance-based comparison
to detect paste collisions correctly
- resolve-edit-fills: Add cycle detection to prevent infinite
loops with corrupted parent chains
Made collision-step, available-offset-step, and resolve-edit-fills
public for better testability.
Added comprehensive tests for all fixes covering both exact and
floating-point coordinate scenarios.

* 🐛 Fix path editor code review findings
Fix issues identified during code review of path editor enhancements:
- Fix unused binding lint warning in distribute-content that blocked CI
- Fix collision-step floor comparison to use round instead of floor,
correctly detecting collisions when coordinates drift slightly below
integer boundaries
- Fix resolve-edit-fills to recurse through empty parent groups when
searching for inherited fills in nested group hierarchies
- Fix expand-coincident-node-indices to use fuzzy comparison (gpt/close?)
instead of exact equality, handling floating-point divergence after
transforms or rotations
- Remove unreachable dead code in path-point* on-pointer-down handler
- Add tests for collision-step boundary cases, nested group fill
inheritance, and coincident node alignment/flipping

those textures across zoom for progressive previews, and invalidate
by old∪new document coverage so rotate/move edits do not leave
stale fragments on zoom-out.
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.
During view gestures, fast mode renders tiles without shadows or
blur. Writing those tiles into the doc/tile atlas left shadowless
patches when render_from_cache overlayed them on the scaled
preview. Keep the last HQ atlas tiles until the post-gesture
full-quality render completes.
HQ tiles are 512px and the atlas stays at 4096² (64 full-size
slots). Browser zoom plus a forced ?dpr= can need more visible
tiles than that, and a framebuffer larger than the GPU allows.
Pack interest tiles into smaller atlas cells, blit at 512 then
scale, and inset Linear samples so seams do not bleed. Clamp the
canvas backing store and DPR together, wrap Skia at the real
drawingBuffer size, and wait one frame after DPR changes so CSS
client size and overlays stay aligned.
Add a direct container-geometry path for eligible frames: inline blur
when the kernel fits the tile margin, otherwise a cached filter-surface
pass reused across tiles via DropShadowFilterCache on both the direct
and slow render_shape paths.
Move frame shadow logic into shadows.rs. Fix nested/clipped frame
shadows by deferring parent clip to composite time, apply negative
spread via inset, and allow rotated/transformed frames on the direct
path. Skip descendant extrect walks for clipped frames when only
nested drop shadows matter, and skip child silhouettes when the
container fill already covers shadow descendants.
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.
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.

* ♻️ 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.
