[vtkusers] vtkRenderWindow progress event

[Sean Larkin]

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.
