 * Parallel lines, `spacing` apart at `angleDeg`, cut to where `inside(x, y)` is true, as the data of one SVG path (a millimetre of the picture is a millimetre of the paper). Each end is found to a twentieth of a millimetre.
 * @param bounds - The box the lines are laid over.
 * @param spacing - The gap between lines, in millimetres.
 * @param angleDeg - The turn of the lines, in degrees from the x axis.
 * @param inside - Whether a point is in the shaded part.
 * @returns Path data: `M x y L x y` for each stroke.
 *
 * @example
 * ```ts
 * import { hatchPath } from "@johnmorrisdotca/chikyu-earth/sheets";
 *
 * const d = hatchPath({ x0: 0, y0: 0, x1: 20, y1: 20 }, 4, 45, (x) => x < 10);
 * console.log(d.startsWith("M"));
