Blink's Rendering: Fragment Tree to Layer Tree Conversion

The provided text details Blink's rendering pipeline, specifically focusing on the conversion of the Fragment Tree to the Layer Tree within Chromium's RenderingNG architecture. It explains how layout outputs, captured as an immutable Fragment Tree, are processed through a Pre-Paint phase to build paint property trees (for transforms, clips, effects, and scrolls). Subsequently, the Paint phase generates display items grouped into paint chunks, each associated with a property tree state. Finally, the layerization algorithm (handled by the PaintArtifactCompositor) evaluates these paint chunks, applying merging heuristics and compositing reasons, to create a cc::Layer tree ready for GPU rasterization and display, with CompositorElementIds ensuring efficient synchronization for animations and scrolling.
