  21 /*
  22 Simple but all-in-one plugin implementation. Resembles the look and feel of
  23 MFC control-bars. The class handles painting of the pane and the items in it;
  24 it generates bar/layout customization events, when the user right-clicks the bar/pane.
  25 Hooking an instance of this and row-layout plugins for each pane
  26 would be enough for the frame layout to function properly
  27 (they are plugged in automatically by the wxFrameLayout class).
