The set of child windows of a window W is the set of windows that have W
as their parent window.  The set of subwindows of W is recursively
defined as the set of windows whose parent is either W or a subwindow of
W.  Hence the child window of a child window of W is a subwindow of W
but not a child window of W.  The set of child windows of W is always a
subset of the subwindows of W.

It would mean substantial changes in code and documentation.  If people
think it's worth the effort I can try to do that.
