Function bezierGestalt

bezierGestalt(
    p0: Writable<Vec>,
    p1: Writable<Vec>,
    p2: Writable<Vec>,
    p3: Writable<Vec>,
): {
    end: Writable<Vec>;
    endTangent: Writable<Vec>;
    start: Writable<Vec>;
    startTangent: Writable<Vec>;
}
Cubic Bezier (p0..p3) → {start, end, startTangent, endTangent}. Moving an endpoint carries its control point (tangent preserved); writing a tangent moves only its control point. Square linear iso — all pairs invariant.
Parameters
- p0: Writable<Vec>
- p1: Writable<Vec>
- p2: Writable<Vec>
- p3: Writable<Vec>
Returns {
    end: Writable<Vec>;
    endTangent: Writable<Vec>;
    start: Writable<Vec>;
    startTangent: Writable<Vec>;
}
