Please go ahead and do the changes, it will make the life of people 
porting VTK44 app to VTK5 much easier !

As a side note, I would like to move the protected function to the 
public ones:

vtkAlgorithm:
virtual void SetNthInputConnection(int port, int index, 
                   vtkAlgorithmOutput* input);


So that VTK44 code:

vtkImageBlend blend
blend SetInput 0 background
blend SetInput 1 foreground

becomes:

vtkImageBlend blend
blend SetNthInputConnection 0 0 background
blend SetNthInputConnection 0 1 foreground

Comments ?
