Canvas rendering is a major remaining path where WebContent directly owns GPU-facing drawing state. Back 2D and WebGL canvas contexts with remote Compositor transports, so WebContent talks to canvas surfaces through IPC while the Compositor owns the rasterization resources. This is a large step toward GPU sandboxing because canvas GPU work now lives behind the Compositor boundary. It also gives OffscreenCanvas the process-independent canvas plumbing that HTMLCanvasElement now uses, making worker-owned canvases possible without another WebContent-local rendering path.
