pub fn use_canvas(

fn app() -> Element {
    let value = use_signal(|| 0);

    let canvas = use_canvas(move || {
        let curr = value();
        Box::new(move |canvas, font_collection, area, scale_factor| {
            // Draw using the canvas !
            // use `curr`
        })
    });

    rsx!(Canvas { canvas })
