What I want is if an application has a control panel window atop it's
main window, and you full-screen the main window, the control panel
remains atop the fullscreen window, and does not (even temporarily) go
This means that before raising the fullscreen window above the panel,
this control panel must be raised first, and then the fullscreen window
placed below it.
The best way I see to do this is to to not have the compositor reorder
the window. Instead the client will raise it's control panel window,
then raise the fullscreen window to be below it.
There may be other methods by which clients communicate a "stacking
window graph" to the compositor. This has to be an arbitrary directed
acyclic graph of windows and clients must be able to modify it
synchronously with any changes to their state. Each edge in this graph
will have to have information about what other windows may be inserted
between this pair. IMHO this is much too complicated and does not fit
with Wayland's design.
