[numeric]  angle of rotation, in radians. The direction of rotation
is defined such that positive angles rotate in the direction from
the positive X axis toward the positive Y axis. With the default
axis orientation of cairo, positive angles rotate in a c

Applies rotation by <code>radians</code> to the transformation in
<code>matrix</code>. The effect of the new transformation is to first rotate the
coordinates by <code>radians</code>, then apply the original transformation
to the coordinates.
