Y translation component of the affine transformation
yx component of the affine transformation
yy component of the affine transformation
A #cairo_matrix_t holds an affine transformation, such as a scale, rotation, shear, or a combination of those. The transformation of a point (x, y) is given by: <programlisting> x_new = xx * x + xy * y + x0; y_new = yx * x + yy * y + y0; </programlisting>
