Bumping the minimum GTK version to 3.20 will preclude running on OL 7 / RHEL 7 at all (RHEL 7 has GTK 3.8, which is why that minimum was chosen). I think this is OK, but is another reason I want to see a separate JBS issue to bump the minimum.

I mis-remembered the GTK version in OL7. I just tried it on an OL 7 VM I still had lying around, and it also has GTK 3.22 and using this PR, the MonkeyTester with EXTENDED stage style and a HeaderBar runs just fine, including the context menu.

I was more thinking that we would file a new issue to bump the minimum to 3.20 and provide a release note using that bug that JavaFX requires 3.20 as a minimum. If we end up not doing that, then a release note that the extended stage style needs 3.20 would be good.
