2D Graph scene in Rust
summary
Proof-of-concept 2D scene graph in Rust uses WebGPU (Mozilla Rust ref impl) to drive GPU-backed nodes (rectangles, image nodes, pipelines reused) and handles text by CPU-rasterizing to textures. Event callbacks use an id-based caller map and cloneable handle pattern (Rc+RefCell) to avoid borrow-checker pitfalls. Prototype runs and renders interactive buttons but is not production-ready: WebGPU spec still evolving, text and large-static-data need subtree-to-texture or virtualization optimizations.
