 * Generates evenly-spaced points along a quadratic Bézier curve

 * @param from - Start point (e.g. route endpoint)
 * @param to - End point (e.g. off-route position)
 * @param interval - Spacing between points in SVG units (default: 8)
 * @param curvature - Arc height as fraction of distance (0 = straight, 0.4 = default arc)
