           WMs each have their little quirks with that.  When you change the

           size hints, they get a ConfigureNotify event with the
jorgen@6899
   845
           WM_NORMAL_SIZE_HINTS Atom.  They all save the hints then, but they
jorgen@6899

jorgen@6899
   850
            - A code-initiated move or resize

slouken@6541

           The following move & resize seems to help a lot of WMs that didn't

           properly update after the hints were changed. We don't do a
jorgen@6899
