The JavaFX runtime logs a warning at startup if the JavaFX classes are not loaded from the expected named module.

I also missed noticing that the following bug is marked with the need for a release note:

[JDK-8196079](https://bugs.openjdk.java.net/browse/JDK-8196079): Remove obsolete Pisces rasterizer

I'll create one shortly and add a comment to this PR when done.
