Summary:  Matrix: Invert, wrong computation

Original Submission:  computation of  the inverse in class Matrix.cs
(System.Drawing/Drawing2D) is wrong, in 
method:   public void Invert()

The  coefficients dx, dy should be computed to:
dx = (m21*dy-m22*dx) / determinant ;
dy = (m12*dx-m11*dy) / determinant ;
