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 // Unfortunatly 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.
