VTK 8.2.0-rc2 ready for testing

The second release candidate for VTK 8.2.0 is ready to try.

You can get it from the downloads page, http://www.vtk.org/download/#candidate or from git with the 8.2.0.rc2 tag.

The changes over rc1 consist of a handful of bug fixes, most notably a change to fix python wheel building. Things could turn up in testing of course, but I anticipate that this version will be retagged as 8.2.0 final in about two weeks.

The full set of changes over v8.2.0.rc1 are

Brad King (1):
cmake: Set policy CMP0083 explicitly to avoid warnings

Cory Quammen (3):
Remove direct disable of GL_SCISSOR_TEST
Silence viewport warnings
Make vtkCleanPolyData work with polylines again

Prabhu Ramachandran (1):
ENH: Facilitate building wheels.

Utkarsh Ayachit (1):
no need to wrap vtkPythonInterpreter.

Please try this version of VTK, and report any issues to the bug tracker so that we can try to address them before VTK 8.2.0 final. Kindly set the 8.2 milestone on your issue and merge requests for 8.2 to ensure that they are tracked during the remainder of the release process. Further, please base / rebase all 8.2 target branches off of the v8.2.0.rc1 tag to ensure minimal merge conflicts with the release and master branches.
