[vtkusers] How to enable the stencil buffer?

[Allie Vacanti]

Stencil masks aren't used often in VTK, though the LabeledContourMapper
will use them, see:

https://gitlab.kitware.com/vtk/vtk/blob/master/Rendering/OpenGL2/vtkOpenGLLabeledContourMapper.cxx#L130

Using them requires enabling stencil buffers via the RenderWindow API
and writing
a new OpenGL mapper or renderpass to setup the GL state. There is not an
existing general way to render arbitrary actors into a stencil buffer that
I am aware of.
