Shape::get_bound assumes 0,0 is inside the bounding box

[MaxVerevkin]

It uses

let mut bound = Bound::default();

as its initial bounding box, which contains all zeroes. If the shape does not contain the origin, this results in an incorrect box. The initial box should probably be something like

let mut bound = Bound {
    left: f64::INFINITY,
    bottom: f64::INFINITY,
    right: -f64::INFINITY,
    top: -f64::INFINITY,
};
