BUG: vtkImageIterateFilter was not copying meta-data.
BUG: vtkImageIterateFilter was not copying meta-data.

After the VTK 4 compatibility removal changes, vtkImageIterateFilter
was no longer copying meta-data from input to output (using passes)
during RequestInformation. This is a temporary fix. I will refactor
this later.
