/*
  Notes:
  - Tool bar grip is a small grabber contained in the toolbar which lets
    a user move the toolbar around, dock and undock it, and so on.
  - The convention is to let single-rebar tool bar grips rearrange the
    bars in a dock site, and double-rebar grips dock and undock.
    This convention is recommended but not enforced.
