If the top regular surface does not occupy the full screen, you can 
still click on that underlying fullscreen surface to active and raise it.
I do not understand why this defeats the whole purpose of letting other 
surfaces be above that fullscreen surface.
And this is the current implementation in both compiz, metacity, mutter 
in linux and even in windows.
We can make it better if the other solution really brings benefits.

I did not assume that. ~  Just curious why you said I assume this~
