§parent_reference_frame_transform: FastTransform<LayoutPixel, WorldPixel>§parent_accumulated_scroll_offset: LayoutVector2D§nearest_scrolling_ancestor_offset: LayoutVector2D§nearest_scrolling_ancestor_viewport: LayoutRect§current_coordinate_system_id: CoordinateSystemId

An id for keeping track of the axis-aligned space of this node. This is used in order to to track what kinds of clip optimizations can be done for a particular display list item, since optimizations can usually only be done among coordinate systems which are relatively axis aligned.

§coordinate_system_relative_scale_offset: ScaleOffset

Scale and offset from the coordinate system that started this compatible coordinate system.

§invertible: bool

True if this node is transformed by an invertible transform. If not, display items transformed by this node will not be displayed and display items not transformed by this node will not be clipped by clips that are transformed by this node.

§preserves_3d: bool

True if this node is a part of Preserve3D hierarchy.

§is_ancestor_or_self_zooming: bool

True if the any parent nodes are currently zooming

§external_id: Option<ExternalScrollId>

Set to true if this state represents a scroll node with external id

§scroll_offset: LayoutVector2D

The node scroll offset if this state is a scroll/sticky node. Zero if a reference frame.
