[vtkusers] vtkRenderWindow progress event

[Sean Larkin]

I tested the StartEvent and it works fine.  When I call the Render() method
the start function that I set is entered as expected.  I then checked to
make sure that my RenderEvt was being registered and it was.  For some
reason the ProgressEvt is never fired, thus my function is never called.
Could this have something to do with using Activiz.NET?

The documentation says that the RenderEvt is supported and Intellisense in
Visual Studio says that it does as well.  The problem is that when I set the
RenderEvt function as shown below, that the my progress function is never
entered when the code is run.  Why would this happen?

The RenderWindow invokes: StartEvent, EndEvent, AbortCheckEvent and
RenderEvent.
