docs: Set this matrix to be a simple scale matrix, which scales all axes uniformly by the given factor.
  <p>
  The resulting matrix can be multiplied against another transformation
  matrix to obtain an additional scaling.
  <p>
  In order to post-multiply a scaling transformation directly to a
  matrix, use {@link #scale(float) scale()} instead.

  @param factor
  the scale factor in x, y and z
  @return this
