Not a rust developer, but this seems like an opportunity for Egui to have switchable layout engines.

If you want a simple, one pass layout that super fast, you use the fast-and-dumb-on-purpose-engine. If you want a fancy dynamic scaling layout with breakpoints and blah blah blah, you use the whole-damn-browser-engine.

Thinking along the lines of geometry managers in Tk. Or wxWidgets Sizers.

Maybe I am missing something basic and this won't work/doesn't address the problem.

But maybe there's good prior art to learn from here.
