[vtkusers] Delete() usage

[Jean-Hugues Royer]

Hi,

In fact I'm using C# (Activiz) and I call Dispose() instead of Delete().

My guess was that Dispose() was calling Delete() internally and that's 
why I tried to ask a generic question.

Unfortunately using VTK_DEBUG_LEAKS is not possible with C# (AFAIK ?) so 
I need to understand exactly how the memory management works to ensure 
no memory leak is present.

Your answer raise another question, I wonder how the C++ (not .NET) 
garbage collector is initialized by Activiz, any one knows ?

Regards.
