Fonts and features too small on HDpi display

@snhirsch Thank you for your feedback.

While the hDPI problem with Java apps on Windows and macOS have been solved since Java 11 or so, the situation on Linux seems to be more complex, as it depends also on the desktop manager.

On my Ubuntu 22 with Gnome, I was able to change the scaling using -Dsun.java2d.uiScale=2.0. See https://stackoverflow.com/questions/58699877/how-to-fix-scaling-of-a-java-based-application-on-a-high-dpi-display-in-linux.

• Open a terminal and go to the directory where Antares is installed. In my case, this is /opt/antares.
• Go to ./lib/app
• Set write permissions on Antares.cfg, e.g. by "sudo chmod a+x Antares.cfg"
• Edit the file and add -Dsun.java2d.uiScale=2.0
• Save
• Restart Antares

In my case, the UI is now scaled by a factor 2.

Thanks, Andreas! In the interim I discovered a slightly different workaround that seems to accomplish the correct scaling:
$ GDK_SCALE=2.0 /opt/antares/bin/Antares
Under KDE this can be done by a quick edit to the .desktop file. Might be worth adding some discussion to the FAQ? (If it's there already and I missed it - shame on me...)

@snhirsch Thanks for suggesting to add the workaround to the FAQ. I'll do that with the next release update.
