#cairo_matrix_t is used throughout cairo to convert between different
coordinate spaces. A #cairo_matrix_t holds an affine transformation,
such as a scale, rotation, shear, or a combination of these.
The transformation of a point (<literal>x</literal>,<literal>y</literal>)
is given by:
</para>
<programlisting>
x_new = xx * x + xy * y + x0;
y_new = yx * x + yy * y + y0;
</programlisting>
<para>
The current transformation matrix of a #cairo_t, represented as a
#cairo_matrix_t, defines the transformation from user-space
coordinates to device-space coordinates. See cairo_get_matrix() and
cairo_set_matrix().
