Function vecDot

vecDot(a: Vec2, b: Vec2, origin?: Vec2): number
Returns the dot product of two vectors
Parameters
- a: Vec2
- b: Vec2
- Optionalorigin: Vec2
  If not passed, defaults to [0,0]
Returns number
dot product result
Remarks
The scalar overload can avoid temporary tuple allocations in hot code paths.
Example
```
vecDot([2, 0], [2, 0]);   // returns 4
```
