win: use correct geometry in calculation of window frame region 

Use window geometry (width, height) including border-width as the base
for frame region calculation with `_NET_FRAME_EXTENTS`, instead of
including the extents themselves.
Fixes issues where the frame would get incorrectly blurred *outside* the
window area.

fixes: #413 #590
