The CPU pushes just roughly basic draw information to the GPU, where the fragment übershader itself applies the corresponding design look with help of 2D SDF math in an always antialiased way then.

I really like the text rendering part. I've been picking away at that problem recently and it's pretty difficult to do correctly.
