    Fix cairo_matrix_transform_distance documentation
    
    * Use dx and dy instead of dx1 and dy1 to match with the arguments
    * Use dx_new and dy_new instead of dx2 and dy2 to match with other parts of the documentation
    * Use xx, yx, xy, yy instead of a, b, c, d to match with other parts of the documentation
    * Remove the last two sentences that doesn't make sense
