Function card_height 

pub fn card_height(
    text_renderer: &mut TextRenderer,
    theme: &Theme,
    card: &ToastCard<'_>,
    width: f64,
) -> f64

Height of a card width wide: the attribution line (the app, and how long ago it arrived), the title, the body clamped to two lines, the actions and the padding. A card never reserves less room than paint_card paints into it.
