bug#29353: [PATCH] Add window divider faces to NS (bug#29353)

[Keith David Bershatsky <esq@lawlist.com>]

Alan:

It appears that the right divider is encroaching on the fringe to a tune of 1 pixel, i.e., the vertical divider is drawing on top of the left side of fringe bitmaps.  Is this related to the patch, or a new issue?

(face-spec-set 'default '((t :background "black" :foreground "red")))

(face-spec-set 'window-divider-first-pixel '((t :foreground "red")))

(face-spec-set 'window-divider '((t :foreground "DarkBlue")))

(face-spec-set 'window-divider-last-pixel '((t :foreground "magenta")))

(with-selected-frame
  (make-frame '((right-divider-width . 8) (bottom-divider-width . 8)))
  (split-window-horizontally))

  (truncation . (left-arrow right-arrow))
  (continuation . (left-curly-arrow right-curly-arrow))
  (overlay-arrow . right-triangle)
  (up . up-arrow)
  (down . down-arrow)
  (top . top-left-angle)
  (bottom . bottom-right-angle)
  (top-bottom . (left-bracket
                 right-bracket
                 top-right-angle
