      Different focus policies:
      <ul>

      <li>ClickToFocus - Clicking into a window activates it. This is
      also the default.

      <li>FocusFollowsMouse - Moving the mouse pointer actively onto a
      normal window activates it. For convenience, the desktop and
      windows on the dock are excluded. They require clicking.

      <li>FocusUnderMouse - The window that happens to be under the
      mouse pointer becomes active. The invariant is: no window can
      have focus that is not under the mouse. This also means that
      Alt-Tab won't work properly and popup dialogs are usually
      unsable with the keyboard. Note that the desktop and windows on
      the dock are excluded for convenience. They get focus only when
      clicking on it.

      <li>FocusStrictlyUnderMouse - this is even worse than
      FocusUnderMouse. Only the window under the mouse pointer is
      active. If the mouse points nowhere, nothing has the focus. If
      the mouse points onto the desktop, the desktop has focus. The
      same holds for windows on the dock.

      Note that FocusUnderMouse and FocusStrictlyUnderMouse are not
      particulary useful. They are only provided for old-fashined
      die-hard UNIX people ;-)
