Function lerpV

lerpV(a, b, t, dst?): Vec4
Performs linear interpolation on two vectors. Given vectors a and b and interpolation coefficient vector t, returns a + t * (b - a).
Parameters
- a: Vec4
  Operand vector.
- b: Vec4
  Operand vector.
- t: Vec4
  Interpolation coefficients vector.
- Optional dst: Vec4
  vector to hold result. If not passed in a new one is created.
Returns Vec4
the linear interpolated result.
