ScrollBarView etc... needs redesign to utilize new View architecture

[tig]

ScrollBar and ScrollView are still mostly working in #2361 but need a bunch of changes to really work well again.

In addition, I'd like to revisit the pattern used. The new Frames concept should allow any View to have scrolling without having to add and manage a bunch of scroll objects as is needed today. The idea being the Adornments Frame (temporarily called BorderFrame) can host scroll bars and the work I've done to decouple Bounds from Frame such that Bounds could have a non-zero Location should make scrolling much easier on devs.

So, for now #2361 will be no-bueno relative to scroll bar use cases.

Dupe of #2489
