Struct ScrollView 

pub struct ScrollView { /* private fields */ }

A panel that clips its content and scrolls it with the wheel.

It paints like a Panel, so it takes a background and a border through the style builders. Its paint also reports the view’s heights to its bindings, which is how the offset learns its range and the thumb its track.
