I'm just reading around what I can find about xdg-shell and looking at the 
get_xdg_surface_special() calls I note the extra argument is 2/1/0 for 
main/background/other window styles.
I wonder if the 2 and 1 might correspond to the xdg-shell states for maximised 
and fullscreen (which seem to have those numerci values).
If so, perhaps calling xdg_surface_set_maximized () and 
xdg_surface_set_fullscreen() might have the same effect?
