Description Simon Fraser (smfr) 2023-01-30 14:00:00 PST

Having NSScrollerImp objects in the web process doesn't make sense (since they need CALayers to render). We need to refactor ScrollbarsController in a way that makes sense with UI-side compositing.

This is testable via gestures like "two fingers down on the trackpad" which should flash the scrollers.
