Register a rendering hook to gain access to the Canvas. Reactivity managed with manual dependencies.

Usage

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

    let canvas = use_canvas_with_deps(&value(), |curr| {
        Box::new(move |ctx| {
            // Draw using the canvas !
            // use `curr`
        })
    });

    rsx!(Canvas { canvas })
}
