Function vecLengthSquare

vecLengthSquare(a: Vec2, b?: Vec2): number
Returns the length of a vector squared This is the same as vecLength but without the Math.sqrt step, thus avoiding an unnecessary calculation.
Parameters
- a: Vec2
- Optionalb: Vec2
  If not passed, defaults to [0,0].
Returns number
vector length squared
Remarks
The scalar overload can avoid temporary tuple allocations in tight loops.
Example
```
vecLengthSquare([0, 0], [4, 3]);   // returns 25
vecLengthSquare([4, 3]);           // returns 25
```
