vtkCompositePolyDataMapper::ComputeBounds with plain vtkPolyData input
When browsing the code of vtkCompositePolyDataMapper::ComputeBounds I noticed that the branch for computing the bounds from a single vtkPolyData input does not call this->BoundsMTime.Modified() before returning, but the main branch dealing with a vtkCompositeDataSet does. I don't know in what situation this would give problems, and so I don't have a test case that fails because of this but it seems to me to be an inconsistent behavior of the ComputeBounds method.
