Draft: Progress Reporting improvements for `vtkPVThreshold` and `vtkContourFilter`
The internal filter of vtkPVThreshold
that does the actual processing was not
passing progress events to vtkPVThreshold
and as a result no progress is
reported on the GUI during the execution of the filter. This commit fixes the
issue by forwarding the events of the internal filter to vtkPVThreshold
.
Combined with vtk/vtk!9836 (merged) it fixes provides monotonic progress reporting for vtkPVThreshold
.
Moreover, vtk/vtk!9836 (merged) fixes the issue of vtkPVContourFilter
not reporting any progress for Unstructured Grids.
