* \class ExternalTransform
* \brief An external transform.
*
* This transform warps an external transform.
* This transform is NOT meant to be used for optimization. Just use it as an initial transform, or with transformix.
*
* The parameters used in this class are:
* \parameter Transform: Select this transform as follows:\n
* <tt>(%Transform "ExternalTransform")</tt>
*
* The transform parameters necessary for transformix, additionally defined by this class, are:
* \transformparameter TransformAddress: specifies the memory address of the external transform. \n
* example: <tt>(TransformAddress "000002A3CB9AACC0")</tt>
