We were recomputing which widgets to show only when we were on the other side of the repaint boundaries. That doesn't work well for pageable lists because we come to rest exactly on a repaint boundary, which means we don't cull the other page. After this patch, we recompute the set of widgets using an edge-trigger when we hit the boundary. That's better than using a level-trigger so that we don't continuously recompute the set of widget as we sit at the boundary.

!!! Oh, nevermind. I see now that you are changing this API signature. I thought you had just found places that didn't have the right signature.

Yeah, I just made this instance of this pattern match the one we use elsewhere.
