The new and improved vtkm::cont::ColorTable provides a more feature complete
color table implementation that is modeled after
vtkDiscretizableColorTransferFunction. This class therefore supports different
color spaces ( rgb, lab, hsv, diverging ) and supports execution across all
device adapters.
Due to recent changes to remove static arrays that are not supported on
some devices, the function to return all the local point indices on a
face was removed. That left no way to get the structure of cell faces
short of pulling an internal data structure.
This change resurrects a function to get point indices for a face. The
interface for this method has necessarily changed, so I also changed the
corresponding function for getting edge indices.
These changes now allow VTK-m to compile on CUDA 7.5 by using const arrays,
when compiling with CUDA 8+ support we upgrade to static const arrays, and
lastly when CUDA is disabled we fully elevate to static constexpr.
1. Add a 'FastVec' class that copies input vector types to an efficient
Vec type on the stack. Specializations avoid copies of already efficient
types.
2. Update 'WorldCoordinatesToParametricCoordinates' functions to utilize the
'FastVec' class. This should improve performance when the passed in
vectors are of slow types like 'vtkm::VecFromPortalPermute'.
3. Since most input Vec types will convert to the same 'FastVec' type this
also reduces the code generations. Some code refactoring was required for
this.
When the implementation for the cell derivative functions was made, the
special cases for creating the Jacobian for wedge and pyramid cell
shapes was not working. Instead, it just used the hexahedra case for a
degenerate cell. This fixes the issues with the special cases.
There were multiple issues to be fixed. There were some complaints
by the compiler about types. There was a mistake in the pyramid table.
But the biggest issue was a problem with macro expansions. It was
the classic tale of forgetting that you have to encase parameters
in parenthesis to make sure that operator precedence comes out as
expected.
Created split implementation. Parallel radix
sort calls moved to vtkm_cont library.
Added key value radix sorts. SortByKey will invoke
radix sort when the key is a fundamental C++ numeric
or character type.
Added fast path for vtkm::SortLess and vtkm::SortGreater
calls to Sort and SortByKey.
If a global static array is declared with VTKM_EXEC_CONSTANT and the code
is compiled by nvcc (for multibackend code) then the array is only accesible
on the GPU. If for some reason a worklet fails on the cuda backend and it is
re-executed on any of the CPU backends, it will continue to fail.
We couldn't find a simple way to declare the array once and have it available
on both CPU and GPU. The approach we are using here is to declare the arrays
as static inside some "Get" function which is marked as VTKM_EXEC_CONT.

There are still some warnings left:
* Some text in markdown files are incorrectly picked up as
doxygen commands
* ArrayPortalTransform weirdly inherits from a specialized
version of itself. It's technically correct C++ code, but
gives doxygen fits.

Previously once an ArrayHandle was stolen it was placed in an invalid state
where it could not used again by VTK-m. Now instead after being stolen it
is placed into a state where it is identical to memory allocated outside
of VTK-m and passed in.
