Although the results are correct in Chrome (same result in software or hardware), the test is still failing since LayoutTestController does not seem to do the right thing for composited layers.  I think we need a way to make LayoutTestController.display() (or more precisely, WebViewHost::displayRepaintMask) write its results into the composited layer, rather than on top of the framebuffer.

So in this case, we shouldn't rebaseline (commit a new expected result), since the result is still wrong until LayoutTestController is fixed.
