`tween_after == Shape` was stored on keyframes but never read. Now the render path morphs geometry across a shape-tween span: - VectorGraph::interpolated(other, t): same-topology lerp of vertex positions, edge curves, stroke widths and stroke/fill colours. Returns None when topology differs (counts, deleted flags, edge endpoints, fill boundaries), so the caller holds the source keyframe. - VectorLayer::tweened_graph_at(time): returns an owned morphed graph for a shape-tween span whose two keyframes share topology, else borrows the held keyframe. Editing still uses graph_at_time (the held keyframe). - Renderer (Vello + CPU paths) renders via tweened_graph_at. - SetTweenAction + wired the previously-stubbed "Add Shape Tween" menu. The typical workflow — keyframe, duplicate it (same topology), move vertices, Add Shape Tween — now morphs between the two. Non-matching topology falls back to a hold. |
