Fields

clip_id: ClipId

The id of the clip this scroll frame creates

scroll_frame_id: SpatialId

The id of the space this scroll frame creates

content_rect: LayoutRect

The size of the contents this contains (so the backend knows how far it can scroll).

clip_rect: LayoutRect

parent_space_and_clip: SpaceAndClipInfo

external_id: Option<ExternalScrollId>

image_mask: Option<ImageMask>

scroll_sensitivity: ScrollSensitivity

external_scroll_offset: LayoutVector2D

The amount this scrollframe has already been scrolled by, in the caller. This means that all the display items that are inside the scrollframe will have their coordinates shifted by this amount, and this offset should be added to those display item coordinates in order to get a normalized value that is consistent across display lists.
