Please review fix for JDK9:

bug: https://bugs.openjdk.java.net/browse/JDK-8149115

webrev: http://cr.openjdk.java.net/~ssadetsky/8149115/webrev.00/

Currently the hidpi support on linux only reads GDK_SCALE environment 
variable to get the native scale. Although, Gnome3 and Unity DE use own 
settings to control the interface scale. The fix adds possibility to 
read those settings to make java apps hidpi scale similar to the native 
apps. Currently only integer scale values are supported. If native scale 
is not an integer value it is rounded to the nearest integer.
