3199e478a1 spatial/r3: harmonize Vec API with num/quat.Number 
Migration to the new API can be achieved with this rsc.io/rf script:

```
rf ex {
	import "gonum.org/v1/gonum/spatial/r3";
	var p,q r3.Vec;
	var f float64;

	p.Add(q) -> r3.Add(p, q);
	p.Sub(q) -> r3.Sub(p, q);
	p.Scale(f) -> r3.Scale(f, p);
	p.Dot(q) -> r3.Dot(p, q);
	p.Cross(q) -> r3.Cross(p, q);
	p.Rotate(f, q) -> r3.Rotate(p, f, q);
}
```

Updates gonum/gonum#1553.
