FX bug : https://bugs.openjdk.java.net/browse/JDK-8195808
FX webrev: http://cr.openjdk.java.net/~prr/8195808/
This updates FX to use proposed new standard Java SE API to specify
an owner window for a Java 2D printer dialog, or to specify "always on top"
behaviour where that is not possible.
The Java SE change is proposed here :
http://mail.openjdk.java.net/pipermail/2d-dev/2018-May/009231.html
The FX change is a simple switch of the class name to use the new class
name.
The rest is removal of now defunct build code.
