dep/animia: add libutil method I changed the "linux" method to be "proc", because it isn't exactly Linux specific this commit also has some changes to the x11 stuff: instead of enumerating over only top-level windows, we iterate over ALL of them this is because many X11 apps actually use multiple windows for some reason, I still can't get it to work with VLC, but it picks up Firefox...
