Change pipeline state viewers so minimum panel size is smaller

* Add scroll areas for the larger tabs and allow pipe flowchart to
  resize to its minimum size if needed.
* The idea here isn't that anyone will seriously try to use the pipe
  view at 500x200 but more that the minimum size doesn't become a
  problem while moving around windows or panels, or resizing temporarily
