Struct ScrollSurface 

pub struct ScrollSurface {
    pub id: WidgetId,
    pub bounds: Rect,
    pub scrollbar: Option<SurfaceScrollbar>,
}

A scrollable surface registered during paint. The consumer pushes one entry per scrollable widget each frame; dispatch_scroll hit-tests the list to route wheel events to the right widget.

Push in paint order (back-to-front). The dispatcher walks last-to-first so the topmost-painted surface wins on overlap — same semantics as ModalStack.

Fields

id: WidgetId

bounds: Rect

scrollbar: Option<SurfaceScrollbar>

Optional scrollbar geometry. When present, dispatch_click can route thumb clicks (auto-start drag) and track clicks (page up/down) without per-backend code.
