 // This class walks the whole layout tree, beginning from the root FrameView, across
 // frame boundaries. The walk will collect special things in the layout tree and create
 // paint property nodes for them. Special things include but not limit to: overflow clip,
 // transform, fixed-pos, animation, mask, filter, ... etc.
 // It expects to be invoked after layout clean, i.e. during InPaintPropertyUpdate phase.

Nit: this comment should be updated to not use InPaintPropertyUpdate anymore.

Done.
