  23  * Simple, but all-in-one plugin implementation. Resembles look & feel of
  24  * to MFC control-bars. Handles painting of pane and items in it.
  25  * Fires bar/layout customization event, when user right-clicks bar/pane.
  26  * Hooking an instance of this and row-layouting plugins per each pane,
  27  * would be enough for the frame layout to function properly.
  28  * (they are plugged in autimatically by wxFrameLayout class)
