Chromium Animation Architecture: Blink and Compositor Thread Integration

The provided documentation outlines the dual-thread animation architecture within the Chromium browser, specifically focusing on the interaction between the Blink rendering engine and the cc compositor. Blink serves as the primary authority for animation logic and timing, determining if an animation is eligible to be offloaded to the compositor thread for better performance. If an animation qualifies, it is promoted to the cc system, which allows it to continue running smoothly even when the main thread is occupied with heavy tasks. This handoff occurs through a synchronized commit pipeline where state is pushed from the main thread to the implementation thread without standard IPC. While the compositor handles efficient updates to properties like opacity and transforms, Blink remains responsible for the full Web Animations timing model and style interpolations. Ultimately, this architecture ensures visual fluidity by separating high-level semantic rules from low-level frame production and property tree mutations.
