Blink PaintPropertyTreeBuilder: Lifecycle, Operation, and Integration

The provided text offers a comprehensive technical examination of the PaintPropertyTreeBuilder within Blink’s rendering engine, detailing its function during the PrePaint phase of the document lifecycle. Its primary role is to efficiently create and update the four core property trees—Transform, Clip, Effect, and Scroll—which establish the coordinate system and visual context for all painted content. The process is orchestrated by the PrePaintTreeWalk, which utilizes dirty bits on layout objects to ensure updates are incremental and constrained, often skipping large, unchanged subtrees for performance. Furthermore, the document explains how mechanisms like contain: paint create isolation boundaries to block property updates from cascading unnecessarily, and it covers how the resulting property trees are essential for subsequent Painting and Compositing phases, ultimately linking layout changes to GPU-ready graphical instructions.
