Drawing a circle is kind of cheating. The hard part of scaling is drawing UI elements like raster icons or 1px hairlines to look non-blurry.

And doing so actually using X not OpenGL.

Toolkits don't use X to do much (if any) drawing these days. They all use something like cairo or skia or -- yes -- OpenGL to render offscreen, and then upload to X for display (or in the case of OpenGL, they can also do direct rendering).

Yes toolkit authors have realized they have to avoid X11 as much as possible if they want to have good results.

This one of the major motivations as to why X11 guys decided Wayland was a good idea.

Because having your display server draw your application's output instead of your application drawing the output is a bad idea.
