The divide by zero happened when mapping a surface to a depth buffer.
Some rays terminated at the origin, which is a singularity in the
project matrix.
This might be indicative of a larger problem. Rays really shouldn't
terminate before the near plane.
There were apparently some fields copy/pasted from the 3D version were
not used in the 2D version (probably because they had no meaning). In
one case, one was erroneously normalized, and could cause a floating
point exception.
When computing the cost for splitting, if a regions was empty you would
get a floating point error when multiplying the (invalid) region bound
(inf or -inf) with the number of points (0). It would then check for NaN
costs and reset that. This worked but caused a floating point exception,
which is problematic for some users.
Instead, check for empty regions before computing the cost and reset the
cost that way.
Singular matrices cannot be LUP factorized, so this condition is
detected and returned in a `valid` flag. However, when the detection
happened, the rest of the computation continued to happen. This could
lead to floating point exceptions, which some applications do not like.
So, when an invalid array is detected, return immediately.
Some functions are supposed to behave correctly when given a NaN. This
might only be valid if floation point exceptions are not trapped, so
disable trapping for these tests.
Some simulations trap floating point exceptions to ensure that their
code is working correctly, and we want VTK-m to work correctly in their
code. To check this, we want to turn on floating point exception
trapping in our test code. This is very implementation-specific, so for
now we are just turning it on for GCC. This will at least alert a
problem on some of the dashboards.

`UnknownArrayHandle` supported an `Allocate` method to change
the size of the underlying array without knowing its type.
However, it did not give all the features of `ArrayHandle`'s
allocate. Namely, you could not specify that the data should
be preserved and you could not provide a `Token` object. This
change adds these (optional) parameters.
It updates the ReleaseProcess.md document to describe our bi-branchial
workflow composed by a release branch and master branch
It also adds ReleaseHotFix.md which describes how to perform a HotFix
onto master/release branch.

Sourcing the file installed on dragnipur is causing a CMake error. I
don't know if it is an install error or a problem with FindTBB.cmake,
but this should get around the problem by just using the "old" method
for finding TBB.
TBB 2020 introduced a new class called `task_group`. TBB 2021 removed
the old class `task` as its functionality was replaced by `task_group`.
Our parallel radix sort for TBB was implemented using `task`s, so change
it to use `task_group` (which actually cleans up the code a bit).
The code in `vtkm/cont/Testing.h` now requires a library, which is not
built if testing is not built. Thus, the benchmarking code was giving a
compile error if benchmarking was on but testing was off.
Change the benchmarking to not rely on anything in the Testing
framework. This means using classes in `vtkm/source` instead of
`MakeTestData`. Also avoid using the `TestValue` defined for the tests.
(In one case, we have a simple replacement.) Also had to fix a problem
with a header file not defining everything it needed to compile.
Years ago we discovered a problem with TBB's parallel sort, which we
patch in our local repo and submitted a change to TBB, which has been
accepted.
The code to decide whether to use our parallel_sort patch does not work
with the latest versions of TBB because it requires including a header
that changed names to get the TBB version.
We no longer support any TBB version with this bug, so just remove the
patch from VTK-m.
The latest version of TBB changes the include directory where the
version is stored, so the old version of FindTBB.cmake would fail
because it could not open this file. This issue has already been fixed
by the FindTBB.cmake in VTK, so pull the latest version of that.
