After the last patch, after each resize the X server fills the complete wibox
with its background color which means that the widgets will still flicker. This
patch fixes this by setting the wibox' bit gravity to NorthWest.
This means that if a wibox is enlarged, only the new, larger part will be filled
with the wibox' background color and the rest of the wibox' content will be left
intact. With this patch I couldn't see any flickering anymore.
