cc::Viewport: Engine of Compositor Interaction

The source provides a detailed architectural examination of Chromium’s cc::Viewport class, which is a critical, stateful controller within the rendering engine's compositor responsible for all high-performance viewport interactions. It explains that the class manages the complexity of the dual-viewport model, which separates the static Layout Viewport from the user-visible Visual Viewport to enable smooth pinch-zooming without expensive relayouts. The analysis traces how cc::Viewport facilitates compositor-threaded scrolling and zooming by translating user input gestures into highly efficient mutations of the Property Trees, specifically the ScrollTree and TransformTree. Ultimately, the text establishes that this specialized component is the engine enabling a fluid user experience by isolating high-frequency tasks from the main rendering thread.
