http://trac.webkit.org/changeset/114811 purported to rebaseline a bunch of GTK tests, but appears to have inadvertently changed LayoutTests/css3/zoom-coords-expected.txt as well. (See: <http://trac.webkit.org/changeset/114811/trunk/LayoutTests/css3/zoom-coords-expected.txt>) Perform a partial rollout of that change to fix the build results of now-broken bots.
Jer Noble reverted css3/zoom-coords-expected.txt in <http://trac.webkit.org/changeset/114918>.
Oops! I inadvertently committed LayoutTests/css3/zoom-coords-expected.txt. Thanks Jer Noble for reverting the change to this file.
