This release bundles three independently-useful pieces of work that
overlap heavily in shared files (types, store, i18n, App, CanvasStage,
tests), so they ship together.
SVG asset editor
- New asset kind 'svg' (SvgAsset { canvas, layers }), authored from
inside the existing shape primitives (rect / circle / text / polygon /
freeform). "+" button under the Images sidebar header; opens a
sub-editor that swaps the library sidebar for a dedicated layer
panel, hides the timeline, and uses the same canvas-resize flow
("Edit canvas size" via right-click → no Document settings entry
while in scope). Children carry a single t=0 keyframe each.
- Multi-select rotation in SVG scope only: a temporary group pivot
appears at the selection centroid (draggable), rotation around it
shifts each layer's x/y/rotation. Pivot follows the centroid drift
on Konva-transformer scale/move. Outside SVG, transformer
rotateEnabled stays off (group-rotate write-back is unreliable
per prior feedback).
- Authored SVGs are placed as layers in the main scene and rendered
via drawMaskedGroup at t=0; thumbnails surface in the sidebar via
renderSvgThumbnail. Drop / click / drag / dbl-click-to-edit work
via a transparent svg-hit catcher rect routed in the stage handler.
- Freeform default stroke is red (#e23b3b) so the open path is
visible immediately. addDrawingPoint resolves the layer through
activeLayers so freeform draws correctly inside SVG and clip
scopes too.
End keyframe type
- Keyframe.kind: 'normal' | 'end'. End kfs carry no props, mark the
visibility cap. layerActiveRange / isLayerActiveAt / sampleKeyframeSet
ignore them for interpolation and use them only as the visible-from
/ visible-until bounds.
- One-time migration in normalizeProject synthesizes an end kf at the
time of the last normal kf for layers that relied on the legacy
"last kf = disappears" semantics; layers using hold:true to extend
visibility past the end skip the migration. Idempotent.
- Timeline UI: new "+end" toolbar button (multi-select fan-out, toggle),
"Convert to end" / "Back to normal" entries in the kf context menu
(easing / still-frame / duplicate hidden for end kfs), end kfs
render as a flat axis-aligned square (vs. the diamond-rotated normal
kf). Render filter drops end kfs that collide with a normal kf at
the same time so legacy migrated projects don't read as four-point
stars.
UX polish
- TAB-collapse stage anchoring: the canvas content stays put when the
asset / properties asides toggle (CanvasStage's ResizeObserver
compensates viewX/Y by the container's bounding-rect drift).
- Topbar clipboard button copies the current frame to the system
clipboard as a PNG via navigator.clipboard.write([ClipboardItem]).
- chromeClick predicate adds .timeline to the editing-panels bail so
the synthetic click after a Timeline box-select drag no longer
wipes the just-committed kf selection.
- Right-click on a polygon vertex stops propagation so the vertex
context menu wins instead of the generic stage menu opening on top.
