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.
* 🐛 Fix render_to_pdf call in the ToUnicode test
The test passed a scale argument that render_to_pdf does not take, so
the render-wasm test build failed to compile.
* 🐛 Draw masked group inner shadows in PDF and multi-element export
The CPU renderer behind PDF and multi-element raster export drew a
masked group's drop shadow but never its inner shadow, so the masked
content came out flat. Wrap the masked content in a layer that draws
the inner shadows over it, as the GPU single export does.
* 🐛 Export every visible inner shadow of a masked group
The workspace skips shadows too small to see at the current zoom, to
render faster. Export has no such need, so draw every visible inner
shadow instead of filtering by scale.
* 🐛 Fix shadows derived from imported SVG filters
* 🐛 Fix inherited group fills in exports and group drop shadows
* 🔧 Run exporter tests on render-wasm changes
* 🎉 Render different stroke styles per side
* 🔧 Stabilise per-side stroke snapshots against clip id churn
SVG clip ids come from a counter that lives for the whole test
process, so a snapshot holding one depends on how many clips other
tests emitted first. The masked-group export tests that landed on
develop shifted that count and broke two per-side snapshots, whose
only diff was the id.
Route the remaining per-side snapshots through with_stable_clip_ids,
which renumbers ids in order of appearance. No snapshot in the suite
now carries a generated id.

* 🐛 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.

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.
* ✨ 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.
