Function scale

scale(m, v, dst?): Mat4
Scales the given 4-by-4 matrix in each dimension by an amount given by the corresponding entry in the given vector; assumes the vector has three entries.
Parameters
- m: Mat4
  The matrix to be modified.
- v: Vec3
  A vector of three entries specifying the factor by which to scale in each dimension.
- Optional dst: Mat4
  matrix to hold result. If not passed a new one is created.
Returns Mat4
The scaled matrix.
