Also separate out the parallel functionality and move it into a subclass,
vtkPMergeArrays.

This should quiet output when vtk3DLinearGridPlaneCutter executes.

It can be used only when boundary cells alone are extracted.

Added new threaded methods in vtkPolyData and vtkBoundingBox
for computing GetBounds(). Added a comparison test for the
methods vtkPolyData::GetBounds(), vtkPoints::GetBounds(),
and vtkBoundingBox::ComputeBounds(). The speed improvements on
large meshes is approximately 10x.

Also, the new vtkCellArray API, and the vtkArrayDispatch
framework is used. Note, as before, this new vtkPolyData::GetBounds()
only considers points used by cells to determine the bounding box.

Performance considerations required tuning the vtkCellArray and
vtkCellArrayIterator to share memory when possible (i.e., avoid
copying). Also cleaned up documentation and API for these classes.
A test was added to ensure that iterator is functioning properly
(e.g., is faster, sharing storage buffer as appropriate).

Finally discovered an error in vtkParametricKuen which was
generating NaN on some systems, which messed up the GetBounds()
computation.

In C++11 the return type of a lambda can be only inferred if the
lambda is a single statement with an explicit `return`. So for
functions that have no return, we have to explicit state that
they don't have a return.

Simple fix to avoid divide by zero

bunch of missing override qualifiers on destructors

This reverts commit a7800961, reversing
changes made to f89fc4ea.

Updating `vtkPipelineSize` API to avoid dependency on mapper and hence
on `VTK::RenderingCore`.

vtkLineSource now support ability to manually specify the locations
along the line segment(s) where to add intermediate sample points.

This is needed to addresses paraview/paraview#19236.

vtkCellCenters is a fairly basic filter that uses vtkCell API.

This reverts commit 481b902f, reversing

This reverts commit 039fc8f4, reversing
changes made to 6fa0fb57.

vtkLinearCellExtrusionFilter is a modeling filter.
It takes polygonal data as input and generates an unstructured grid data on output.
The input dataset is swept according to the input cell data array value along the cell normal and creates new 3D primitives.
Triangles will become Wedges, Quads will become Hexahedrons, and
Polygons will become Polyhedrons.

The improves and optimize the LagrangianParticleTracker multithread implementation by :

* Avoiding useless allocation
* Using thread-level variable
* Avoiding using mutex by doing actual reduction of the output
* A few bugfixes and memleaks fixes
* Add QuadraticRoot to vtkMath
* Add a vtkBilinearQuadIntersection class

for some reason the decltype seems to fail.

These files were listed more than once via other means (usually
`CLASSES`).

Remove a few unnecessary virtual keywords as well.
