/** \class GPUCompositeTransformCopier
* \brief A helper class which creates an GPU composite transform which
* is perfect copy of the CPU composite transform.
*
* This class is NOT a filter. Although it has an API similar to a filter, this class
* is not intended to be used in a pipeline. Instead, the typical use will be like
* it is illustrated in the following code:
*
* \code
* struct OCLImageDims
* {
* itkStaticConstMacro( Support1D, bool, true );
* itkStaticConstMacro( Support2D, bool, true );
* itkStaticConstMacro( Support3D, bool, true );
* };
*
* using OCLImageTypes = typelist::MakeTypeList< short, float >::Type;
* using TransformType = itk::CompositeTransform< float, 3 >;
* using CopierType = itk::GPUCompositeTransformCopier< OCLImageTypes, OCLImageDims, TransformType, float >;
* auto copier = CopierType::New();
* copier->SetInputTransform(CPUTransform);
* copier->Update();
* TransformType::Pointer GPUTransform = copier->GetModifiableOutput();
* \endcode
*
* Note that the Update() method must be called explicitly in the filter
* that provides the input to the GPUCompositeTransformCopier object. This is needed
* because the GPUCompositeTransformCopier is not a pipeline filter.
