RetainedImage is being deprecated. Migrating away.

[miketwenty1]

I got RetainedImage working a while back with my bevy app, but I see it's going to be deprecated in favor of egui::Image.
I was struggling to get the qr code appearing. egui::Image's require lifetimes it seems and that apparently doesn't play nice with the bevy Resource system I was using that requires static lifetimes. Any help would be great. Currently getting a blank qr code in the egui window.

#[derive(Resource, Deref)]
pub struct MyQr(pub String);

#[cfg(web_sys_unstable_apis)]
pub fn spawn_qr_code(mut commands: Commands, i_data: Res<IDataFromServer>) {
    info!("spawning QR code");
// ...
// create some qrcode svg string and save it to a resource

    let image = code
        .render::<svg::Color>()
        .min_dimensions(200, 200)
        .max_dimensions(300, 300)
        .dark_color(svg::Color("#800000"))
        .light_color(svg::Color("#ffff80"))
        .build();

    commands.insert_resource(MyQr(image));
}

#[cfg(web_sys_unstable_apis)]
pub fn update_qr_code(
    qr: Res<MyQr>,
    i_data: Res<IDataFromServer>,
    mut egui_context: EguiContexts,
) {
    egui::Window::new("i")
    .show(egui_context.ctx_mut(), |ui| {
        let qr_clone = qr.0.clone();
        let bevy_egui::egui::Vec2 { x, y } = ui.available_size();
        let smaller = x.min(y);
        let qr_bytes = qr_clone.as_bytes().to_vec();
        let someimg = egui::Image::from_bytes("bytes://qrcode.svg", qr_bytes);
        let button_min_size = bevy_egui::egui::Vec2 { x: 120.0, y: 60.0 };
        ui.with_layout(egui::Layout::bottom_up(egui::Align::Center), |ui| {
            someimg.load_and_calc_size(ui, bevy_egui::egui::Vec2::new(smaller, smaller));
        });
    });
}

I have a similar issue where I am currently using RetainedImage and the required lifetime for egui::Image is somewhat prohibitive.

Any comments or updates here?
