Summary0006955: vtkInformation::CopyEntry ignores deep flag
DescriptionMany of the forms of the CopyEntry method in vtkInformation ignore their deep flag. Instead they always do a shallow copy, which of course can lead to some surprising results when a DeepCopy of a vtkInformation or its entries is performed.

I attached a patch to vtkInformation.cxx that should fix the problem.

It seems like none of the vtkInformationKey subclasses provide an implementation for DeepCopy().

Hmm. I must not have noticed that because in my case the missing keys were being recreated again after the copy.

It seems to me that vtkInformationKey::DeepCopy should be a pure virtual class (like ShallowCopy), which would force all of the subclasses to provide an implementation.

Committing Ken's patch to make vtkInformation::Copy()
respect the deep-copy flag. Also added default vtkInformationKey::DeepCopy()
implementation which simply does a shallow copy.
