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