In cases where the form factor of a transformed (e.g. rotated) object is needed, the complex part of the wave vectors can also lie in the x- or y-direction.
In such cases, the form factor should be able to deal with wave vectors that have complex components in any of the three directions.

* Currently, only the real part of the wave vector is transformed
* When using the evaluateForComplexkz functions are called, the z-part of the real wave vectors is currently used to deduce the original incoming (or outgoing) angle (it still contains the z-part in the top air-layer). When the vectors are passed as complex vectors, this information should be retrieved in another way.
