[9] Review request for 8160054: The FileChooser didn't displayed large font with GTK LAF option.

[Semyon Sadetsky]

Hello,

Please review fix for JDK9:
bug: https://bugs.openjdk.java.net/browse/JDK-8160054

webrev: http://cr.openjdk.java.net/~ssadetsky/8160054/webrev.00/

The root case is GTK LnF does not allow to change its default fonts.

The proposed solution let's to use LnF font properties to change the 
defaults.
