lwpolyline vertices defined with spread

[ditjedatje]

Hi,

I bumped into this problem:

func (d *Drawing) LwPolyline(closed bool, vertices ... []float64) (*entity.LwPolyline, error) {
	size := len(vertices)
	l := entity.NewLwPolyline(size)
	for i := 0; i < size; i++ {
		l.Vertices[i] = vertices[i]
	}
	if closed {
		l.Close()
	}
	l.SetLayer(d.CurrentLayer)
	d.AddEntity(l)
	return l, nil
}

shouldn't this be:

func (d *Drawing) LwPolyline(closed bool, vertices [][]float64) (*entity.LwPolyline, error) {

Where the spread operator is replaced with a [] so the vertices are correct.
I tested this change and it works fine.

Thanks
