All my testing looks good apart from a couple of known issues that are being tracked by follow-up bugs.

The CanvasPattern bug that Jay referred to is tracked as [JDK-8347937](https://bugs.openjdk.org/browse/JDK-8347937). The only other issue I've found is one I filed a few days ago:

[JDK-8349561](https://bugs.openjdk.org/browse/JDK-8349561): Preview images on yahoo.com rendered incorrectly
