Prevent border drifting.

Browse Source 
Windows were drifting by FRAME_BORDER_WIDTH pixels when their
borders were toggled on or off.

Windows which had a border before we managed them were drifting
on shutdown and again at startup.  It happened because the absolute
upper-left co-ordinates of a bordered window would in fact be the
upper-left co-ordinates of the border itself, whereas we consider
the client window to have no border and co-ordinates offset by the
titlebar and frame border.
