Modifies a transform such that a rotation of a given number of radians is performed on any points multiplied by the transform.

The function `apply-rotation`

modifies `
transform`
such that a rotation of `
theta`
radians is performed on any points multiplied by the transform. Any operations already contained in the transform occur before the new rotation.

The rotation is around the point (0,0).

See graphics-state for details of how a transform is used.
