Blink's Paint Property Tree Builder: A Surgical Tour of Dragons

The source text provides an extremely detailed, technical overview of the blink::PaintPropertyTreeBuilder class in Chromium, which is responsible for building the rendering pipeline's four synchronized yet independent property trees (transform, clip, effect, and scroll). The document describes this process as a "surgical tour of dragons" because of the combinatorial complexity required to reconcile all CSS, SVG, and layout features (like sticky positioning, fragmentation, and view transitions) across these four topologies during the PrePaint phase. The explanation walks through the structure of the class, detailing the purpose of various helper contexts, the critical decision gates that determine which nodes are built, and complex edge cases like subpixel accumulation, isolation nodes, and fast paths for direct compositor updates. Ultimately, the class ensures that the Chromium rendering engine can correctly express complex relationships—such as effects and transforms—that cannot be modeled by the single DOM tree, thereby enabling features like fast partial updates and fixing rendering paradoxes.
