Function rotate

rotate(m, axis, angleInRadians, dst?): Mat4
Rotates the given 4-by-4 matrix around the given axis by the given angle. (same as rotate)
Parameters
- m: Mat4
  The matrix.
- axis: Vec3
  The axis about which to rotate.
- angleInRadians: number
  The angle by which to rotate (in radians).
- Optional dst: Mat4
  matrix to hold result. If not passed a new one is created.
Returns Mat4
The rotated matrix.
