[EXP] Blink Paint Artifact Compositor: Advanced Architectural Internals

The provided text explains the PaintArtifactCompositor (PAC), a critical bridge in the Chromium engine that converts Blink's paint data into a format the compositor can process. It describes how the system manages performance and correctness by using various update paths, such as fast-track repaints and specialized handling for non-composited scrolling. The technical details focus on PendingLayers as the primary unit for optimizing GPU memory and the logic used to merge or separate layers based on overlap testing and sparsity heuristics. Additionally, the source explores how property trees are mapped to the compositor while maintaining stable identities for animations. The text concludes by outlining debugging strategies and potential architectural improvements for handling complex rendering features like view transitions.
