 * X.H.ManageDocks: ignore struts that cover an entire screen on that screen
 Imagine a screen layout like this:
 
   11111111
   11111111
   11111111
    222222    <--- xmobar here
    222222
    222222
 
 When placing xmobar as indicated, the partial strut property indicates that an
 entire height of screen 1 is covered by the strut, as well as a few lines at
 the top of screen 2. The original code would create a screen rectangle of
 negative height and wreak havoc. This patch causes such strut to be ignored on
 the screen it covers entirely, resulting in the desired behaviour of a small
 strut at the top of screen 2.
 
 Please note that this semantics of _NET_WM_STRUT and _NET_WM_STRUT_PARTIAL is
 different to what is in wm-spec. The "correct" thing to do would be to discard
 the covered portion of screen 1 leaving two narrow areas at the sides, but
 this new behaviour is probably more desirable in many cases, at least for
 xmonad/xmobar users.
 
 The correct solution of having separate _NET_WM_STRUT_PARTIAL for each
 Xinerama screen was mentioned in wm-spec maillist in 2007, but has never
 really been proposed, discussed and included in wm-spec. Hence this "hack".
