OpenJFX: Follow HiDPI Scaling Settings in Fedora Workstation 32 (Gnome)

[Kevin Rushforth]

We will need a new bug ID for this (we never reuse a bug ID for which a 
commit has been pushed). You can file a new bug, mentioning JDK-8137050 
in the Description, at:

https://bugreport.java.com/

Question for other Linux users on this list: are any of you using a 
Linux machine with Hi-DPI scaling? Is it detecting it properly or do you 
have to set the scaling property (either via gsettings or the GDI_SCALE 
env variable)  yourself?
