// .NAME vtkImagePermute -  Permutes axes of input.
// .SECTION Description
// vtkImagePermute reorders the axes of the input. Filtered axes specify
// the input axes which become X, Y, Z.  The input has to have the
// same scalar type of the output. The filter does copy the 
// data when it executes. This filter is actually a very thin wrapper
// around vtkImageReslice.
