pub fn process_system_scroll(
delta: LogicalPosition,
hit_scrollbar: bool,
) -> ScrollResultExpand description
Dispatch a system scroll event and return a ScrollResult describing what
happened.
This is the entry point used by headless integration tests and embedders that
drive scroll programmatically. The richer per-document scroll handling lives
in LayoutWindow::process_scroll; this helper packages a delta into a
ScrollResult for return to callers so the result type is observable from
the public API.
