[Insight-developers] Const Missing in inputs for Process Object

[Luis Ibanez]

Hi,

The array of inputs for Process Object is not const-correct.

In principle there is no reason for a filter to modify its input
so the input should be stored as ConstSmartPointers.

Currently this is done using just SmartPointers.

This constness-defect is propagated through all the Filters
which  basically means that you cannot pass a const image
as input to any filter.      :-/

Does anybody see a conflict in making the array of m_Inputs
in itk::ProcessObject   an array of SmartConstPointers   ?
