Thanks.

Yes.  The NS port seems to put some own interpretation on
internal-border-width as I pointed out in
http://lists.gnu.org/archive/html/emacs-devel/2009-07/msg00594.html .

The Mac port should behave just as in X11, even for fullscreen frames.
(Actually, I noticed the problem with FRAME_LINE_TO_PIXEL_Y when I was
testing fullscreen frames with large internal-border-width.  The
non-toolkit tool bars are used for such frames because the Cocoa tool
bars can't be used for title-bar-less windows on Mac
