Then you are missing one point: We need a structure that can be defined
(a) via some layout specification package as the one provided by ECB,
and (b) from user interactions in order to fit it into the desktop.el
framework.  In the latter case the user won't care about any such
structures, she simply wants her windows back.

The question is what the _standard_ semantics are when a window ceases to
be topmost and we have to move it somewhere else on the stack.
