New issue 449 by beneficial.terminator: Off-by-2*wa_border_width error in  
XMonad.Actions.UpdatePointer
http://code.google.com/p/xmonad/issues/detail?id=449

What steps will reproduce the problem?
1. Enable XMonad.Actions.UpdatePointer
2. Set borderWidth to 100 (or some other large number) in xmonad config
3. Move the mouse pointer to the right of or below a window, then switch  
focus to that window

What is the expected output? What do you see instead?
The pointer should move to the edge or center of the newly focused window.   
Instead it moves as if the focused window is 200 pixels narrower on the  
right and 200 pixels shorter at the bottom.

In XMonad.Actions.UpdatePointer.windowAttributesToRectangle, because of the  
way WindowAttributes is calculated, the dimension
     wa_width wa
should be
     2 * wa_border_width wa + wa_width wa
and analogously the dimension
     wa_height wa
should be
     2 * wa_border_width wa + wa_height wa
.
