Graph groups and comments: fit frames them, the band catches them (#95)

   object's position. Ctrl/Shift-click adds or removes single nodes, dragging any node of a
   selection moves all of them, and `Delete` removes all of them — one undo step either way.
+- **The band catches groups and comments too** (#95), and they end up in the *same* selection as
