  28 // Turning the border on/off by changing the motif_wm_hints property
  29 // works on Irix 4DWM.  Does not appear to work for any other window
  30 // manager.  Fullscreen still works on some window managers (fvwm is one)
  31 // because they allow the border to be placed off-screen.
  32
  33 // Unfortunately most X window managers ignore changes to the border
  34 // and refuse to position the border off-screen, so attempting to make
  35 // the window full screen will lose the size of the border off the
  36 // bottom and right.
