Speed2's UI scaling efforts made me think of an easy way to make new scaled icons to complete the UI scaling. I came up with a script that crafts the icons together from lookup images so you only have to specify each shape and symbol once and don't have to edit hundreds of icons individually.
You can find it here: https://github.com/BlackYps/FAF-Icon-Generator
You can use it to generate icons of almost any size. Detailed usage instructions are on github.
I also attached the set of Icons at 125% scale that I made with the script. They are ready for use.
