// managed by the frame, i.e. resized/moved when the frame is and whose size
// is accounted for in client size calculations - all others should be taken
// care of manually. The CreateXXXBar() functions create this, main, XXXBar,
// but the actual creation is done in OnCreateXXXBar() functions which may be
// overridden to create custom objects instead of standard ones when
// CreateXXXBar() is called.
