That is very informative! I have to say I was pretty mystified by the 
wl_shell_surface object.

Though this implies that there can be more than one shell. Because if 
there is only one shell there is no need for that argument, and the api 
can just be "wl_shell.set_fullscreen(surface)".

What is the meaning of more than one shell? Or is there another reason 
for the shell argument?
