How to run an app headless?

[Thiago Milczarek Sayão]

Hi Johan,

I just wanted to replicate a simple test outside of the testing system to
see why the behavior change in focus is happening on
https://github.com/openjdk/jfx/pull/1110

So the solution Kevin replied to in this email was enough.

The fix for this PR seems to have focused the button that is used in
the MouseEventFirerTest.
testAnchorRight[0], so the
testing values are different (because of the focus decoration shadow).

Before the PR and the change made in
https://bugs.openjdk.org/browse/JDK-8296621 the button does get focused,
but when
the test runs, values are not updated yet.

It's weird because with the PR, focus does get a little bit delayed because
it happens after the window is shown
 (makes sense to me to show and then focus).
