The usage of uint was causing problems with CUDA + MSVC2015 as
type was not defined. Instead we use vtkm::Id as that was the expect
type to be passed to the task

This allows for easier host side logic when determining grid and block
sizes, and allows for a smaller library side by moving some logic
into compiled in functions.
When you have a Vec<Vec<float,3>> it was possible to incorrectly correct
it with the contents of a Vec<double,3>. An example of this is:
using Vec3d = vtkm::Vec<double, 3>;
using Vec3f = vtkm::Vec<float, 3>;
using Vec3x3f = vtkm::Vec<Vec3f, 3>;
Vec3d x(0.0, 1.0, 2.0);
Vec3x3f b(x); // becomes [[0,0,0],[1,1,1],[2,2,2]]
Vec3x3f c(x, x, x); // becomes [[0,1,2],[0,1,2],[0,1,2]]
Vec3x3f d(Vec3f(0.0f,1.0f,2.0f)) //becomes [[0,0,0],[1,1,1],[2,2,2]]
So the solution we have chosen is to disallow the construction of objects such
as b. This still allows the free implicit cast to go from double to float.
So while `Vec3x3 b = x is supported by vtk-m, it produces very incorrect results.
Previously we would compute a 3x3 matrix where each element was a Vec. Using
the jacobain of a single component is sufficient so by using that we safe 2 to
3 times the memory space.
Additionally by moving to doing the derivative as a per component algorithm
we work around the issues found in bug
https://gitlab.kitware.com/vtk/vtk-m/issues/221. In effect when trying to
construct a Vec of Vec from a component of a different floating type e.g.:
Vec3d x(0.0, 1.0, 2.0);
Vec3f a = x;
Vec3x3f b = x;
Vec3x3f c(x, x, x);
Generates bad values vectors such as b which look like:
b: [[0,0,0],[1,1,1],[2,2,2]]
c: [[0,1,2],[0,1,2],[0,1,2]]
Previously, when a Worklet needed a scatter, the scatter object was
stored in the Worklet object. That was problematic because that means
the Scatter, which is a control object, was shoved into the execution
environment.
To prevent that, move the Scatter into the Dispatcher object. The
worklet still declares a ScatterType alias, but no longer has a
GetScatter method. Instead, the Dispatcher now takes a Scatter object in
its constructor. If using the default scatter (ScatterIdentity), the
default constructor is used. If using another type of Scatter that
requires data to set up its state, then the caller of the worklet needs
to provide that to the dispatcher. For convenience, worklets are
encouraged to have a MakeScatter method to help construct a proper
scatter object.

The code had 2 issues:
1. used obsolete 'output' if Git executable was missing. There was a
possibility that output variable was never set and used some garbage
value from parent scope.
2. version pattern matching was too liberal and would match
absolute any long txt so long as it has some numbers in it that matched
a typical version number.
Adding API to DataSet to `CopyStructure` from another dataset. This
copies the cellsets and coordinate systems while leaving the fields
unchanged.
CreateResult no longer copies all input fields to the output dataset
created.
Furthermore, if a Filter subclass doesn't provide `MapFieldOntoOutput`,
then the default implementation simply copies only the selected fields
to the output dataset.
Previously when an external project loaded VTK-m with find_package(VTKm)
and then tried to use anything with OpenGL, you would get compiler (and
probably linker) errors. The problem was that
VTKmRenderingContexts.cmake skipped over the loading of OpenGL libraries
because the vtkm_rendering_gl_context target was imported before this
code was ever called. Correct the problem by going through the motions
of checking OpenGL every time.
Minimizing the need to have complex serialization code in vtkm/cont.
This is first step in moving DIY serialization code out of vtkm/cont. We
need to move that to filter so we can leverage policy correctly
serialize fields.
The vtkm_add_header_build_test was changed to identify "valid" header
files that were actually tested and only adding those to the source
list. This was a mistake. A big part of the point of adding headers that
are not tested to the test build sources is to list them to an IDE.
The test build file did not actually define any symbols, so the linker
might give a warning about it not being used in the library. Define some
unique symbol so that the linker will not complain.
If you tried to create test builds of a header.h and header.hxx, you
would get an error about building two files with the same name (tried to
build header.cxx for both of them). Fixed this by adding the original
extension name to the source file name.
The CMake configuration stopped creating any of the test builds. There
were a couple of errors introduced into this function that needed to be
fixed.
First, the condition on whether the testing should be skipped got
reversed. It was trying to create test build files for all the headers
that were not supposed to be built instead of the ones that were.
Second, the list of source files to build was not created correctly. The
set command that stored the name of the source file got removed, and so
nothing was being added to the list. I restored the variable and used
that consistently for the source file name.
