Apply scaling to this matrix by scaling the base axes by the given <code>xy</code> factors
and store the result in <code>dest</code>.
<p>
If <code>M</code> is <code>this</code> matrix and <code>S</code> the scaling matrix,
then the new matrix will be <code>M * S</code>. So when transforming a
vector <code>v</code> with the new matrix by using <code>M * S * v</code>, the scaling will be applied first!
@param xy
the factors of the x and y component, respectively
@param dest
will hold the result
@return dest
