How to get text scaling value in C++?


I am writing a OpenGL application in C++. I recently discovered that UI elements are very small on high-DPI displays. A bit of research indicates that there is a setting for text scaling factor, which scales up UI elements; how can I read this value from C++ to scale my UI?

I'm not using any libs for UI, it's written in raw OpenGL and uses X for window creation. I'm using OpenGL 3.

As far as I can tell, all the answers there are Windows-specific (they use GDI to figure out the text scaling).
