Just what are the relationship of the various window shutdown
messages?

What should a window do to shut itself down without shutting down its
parent?  WinDestroyWindow(hwndSelf)? Which message should handle saving
the window's state, WM_CLOSE or WM_DESTROY?

My current understanding is that the client window proc should process
WM_CLOSE by invoking WinDestroyWindow() on its frame, and then return 0.
Any resource deallocation or state-saving is done while processing
WM_DESTROY.
