How to let window auto size with browser window size?

[kitepad]

I check out egui_template and compile to web. But ui canvas is fixed size in browser window, can not claim all width even browser window size is bigger.

Check out https://docs.rs/epi/0.12.0/epi/trait.App.html#method.max_size_points

That is really counter-intuitive, isn't it? I can't understand why my app maximizes correctly on the native platform, but needs

fn max_size_points(&self) -> Vec2 {
    vec2(f32::MAX, f32::MAX)
}

on web.
Is this an expected behavior? Maybe we should make default implementation?

P.S.
Main egui demo works perfectly at https://emilk.github.io/egui/index.html, but when compiled locally, its size is incorrect.

It's not ideal, but if we fill the full width WebGL gets really slow in firefox: https://bugzilla.mozilla.org/show_bug.cgi?id=1010527#c0
