// 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.
|
|
|
|
// Unfortunately 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.
