Would be great if you could put the Layer overrides in one block too.

// Layer interface.
CreateLayerImpl();
Update();
...

and then the rest of the methods.

Done.

 
-  void PushPropertiesTo(LayerImpl* layer) override;
-
-  void set_recorded_viewport(const gfx::Rect& recorded_viewport) {
-    picture_layer_inputs_.recorded_viewport = recorded_viewport;
-  }
-
-  DisplayItemList* display_list() const {

Thanks for the cleanup. :)

-    return picture_layer_inputs_.display_list.get();
-  }
