vtkImageBlend SetInput(1, data) doesn't work
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
When vtkImageBlend was converted to the new pipeline, the SetStencil() was mapped to SetInput(1,stencilData). Unfortunately, because this filter is meant to take multiple ImageDatas as input, SetInput(1, ...) should be reserved for the second image data input.
