Transform

4x4 transformation matrix representing position, rotation, and scale

Example:

// Create with specific values
var t = Transform({
    position: Vector3(0, 1, 0),
    rotation: Rotation(0, Math.PI, 0),
    scale: Vector3(1, 1, 1)
});

// Get entity's transform
var worldT = entity.worldTransform;

// Combine transforms
var combined = Transform.multiply(parentT, childT);

// Transform a point
var worldPoint = Transform.transformPoint(entity.transform, localPoint);
