//===========================================================================
// Summary:
//     CXTPTabManagerAtom is a class that has only one purpose, which
//     is to catch the event when a property of the PaintManager has changed.
//     When a property of the PaintManager has changed, the OnPropertyChanged
//     event if called. When the OnPropertyChanged is caught, Reposition
//     is called to recalculate self layout.
// Remarks:
//     This is the base class for CXTPTabManager.  When a property of the
//     CXTPTabPaintManager has changed, then OnPropertyChanged is called
//     to recalculate the layout.  The paint manager can be accessed
//     with the CXTPTabManager::GetPaintManager member.
// See Also: CXTPTabManager::GetPaintManager
