Function min

min(a, b, dst?): Vec2
Return min values of two vectors. Given vectors a and b returns [min(a[0], b[0]), min(a[1], b[1]), min(a[2], b[2])].
Parameters
- a: Vec2
  Operand vector.
- b: Vec2
  Operand vector.
- Optional dst: Vec2
  vector to hold result. If not passed in a new one is created.
Returns Vec2
The min components vector.
