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.
This warning is emitted when the compiler performs an optimization, and wants
you to verify that the presumptions it is making are valid. For this case
we can correctly promise the compiler that the values will not overflow and
the optimizations are correct.
Adding an example that demonstrates how to write a distributed filter
that customizes the execution for all blocks in a MultiBlock. This is a
reinterpretation of the `reduce/all_to_all` example provided by DIY.

Histogram filter now correctly computes the histogram for multiblock
input or when operating in a distributed environment. It employs
reduction to reduce local/per block results to generate the final
output.
This revamps Filter API to improve support for multiblock dataset and
distributed use-cases. Filters now operate on MultiBlock alone thus
`Filter::Execute(MultiBlock&)` is the primary method.
`Filter::Execute(DataSet*)` is only provided as an convenience that
internally puts the dataset into a MultiBlock and calls the primary
method.
Subclasses can provides PreExecute and PostExecute overrides to handle
init/reduction operations for filters with operating on multiple blocks.
Since blocks can be distributed, filters are expected to handle that as
well.
Subclasses can provide `PrepareForExecution(MultiBlock*..)` to customize
behavior for handling multiblock inputs. Default is to simply loop
over blocks.
Updated FieldHistogram worklet to support executing the worklet using a
precomputed range. This will be needed for distributed and multiblock
use-cases.
