Lay out horizontal and vertical Japanese text with kinsoku, ruby,
emphasis, warichu, tate-chu-yoko and proportional font features.
Carry the layout through glyph paths, SVG export and text selection.
Update the Rust and ClojureScript binary formats together, including
the editor bridge and headless exporter. Resolve CJK fallback fonts
and add renderer tests and font fixtures.
When render-wasm is active, generate SVG for the Code inspector and
Copy as SVG from the WASM export path instead of classic SVG codegen.
Add multi-root render_shapes_svg so multi-select stays one document.
Closes#12567
* 🐛 Fix shadows derived from imported SVG filters
* 🐛 Fix inherited group fills in exports and group drop shadows
* 🔧 Run exporter tests on render-wasm changes
Emit an XHTML foreignObject with CSS backdrop-filter for visible
background blur. The inner div uses clip-path:path(...) for the GPU
fill+stroke silhouette (glyph outlines for text). The FO sits outside
opacity and layer-blur filters. Stacked on the masks SVG export work.
Paint the mask subtree into a native <mask mask-type="alpha"> and wrap
content under mask="url(#…)", matching GPU DstIn (soft/group masks).
Drop silhouettes use the same alpha mask; empty-fill SVG paths inherit
group fills.
Closes#11378
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
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.
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.
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
* ✨ 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.
