blink::TransformPaintPropertyNode / ClipPaintPropertyNode / EffectPaintPropertyNode / ScrollPaintPropertyNode

These are the nodes within those four trees. Every piece of painted content (a “paint chunk”) is associated with a tuple of (Transform, Clip, Effect, Scroll) nodes—its PropertyTreeState. This precisely defines where and how to draw it and enables efficient partial updates. (Chromium Git Repositories)

What they carry (high‑value fields)

Change tracking Nodes track change types (PaintPropertyChangeType) so we can choose fast paths (e.g., update value without rebuilding topology). (Chromium Git Repositories)

Hands off to: painting/recording with GraphicsContext + PaintController.
