[gnome-shell/wip/paging] Fixed not updating arrow side when boxpointer doesn't change size (and then it doesn't reallocate it

commit 679c96abdbbdf16a4d19bdb2e8ad009464ca0f14

    Fixed not updating arrow side when boxpointer doesn't change size (and
    then it doesn't reallocate items and doesn't take into account the new
    updated arrow side) but it changes the arrow side because of the
    resolution change.
    Fixed it queuing a redrawing on the border of the boxpointer
