[vtkusers] vtkCommand calldata parameter of Execute()

[Sebastien Jourdain]

Can't you request the informations that you need as you do get a
pointer to the source where the event was generated ?

Otherwise, you just put anything as it's a void pointer. Create your
own struct and that's it. But make sure you know who delete the
pointer...
