The Vec struct already has a Len method, but the squared root could be a performance hit.
When we just want to compare the length of two Vec, it is better to use the squared length.
I suggest adding this in vector.go, under the Len method:
// SqLen returns the squared length of the vector u (faster to compute than Len).
func (u Vec) SqLen() float64 {
return u.X*u.X + u.Y*u.Y
}
I love your work on this repo BTW, it's great and simple to use!
