Well, so was al_toggle_window_frame() then. Should we rename it to
al_set_display_flag()?

Well, we need the flag anyway for al_create_display (same as
ALLEGRO_MAXIMIZED) - so it would very naturally work with just toggling
the flag already. Unlike a resize operation they both are really just a
flag (under X11, indeed "maximize" and "fullscreen" are just two window
properties of the windowing system).

I wouldn't mind having additional extra functions though, they could
simply call al_toggle_display_flag.
