[vtkusers] Strange compile problem for callback function based onvtkCommand

[X Z]

When you're compiling in debug mode, VC tend to add
#define new DEBUG_NEW
to your source code. and
DEBUG_NEW in turn, is #defined as new(THIS_FILE, __LINE__)

On the other hand, operator new is defined in vtkObjectBase as

  void* operator new( size_t tSize );

which takes only one argument.  (There isn't a three argument operator new 
defined).
