/**
* @class vtkMatrixToHomogeneousTransform
* @brief convert a matrix to a transform
*
* This is a very simple class which allows a vtkMatrix4x4 to be used in
* place of a vtkHomogeneousTransform or vtkAbstractTransform. For example,
* if you use it as a proxy between a matrix and vtkTransformPolyDataFilter
* then any modifications to the matrix will automatically be reflected in
* the output of the filter.
