If a worklet doesn't explicitly state an ExecutionSignature, VTK-m
assumes the worklet has no return value, and each ControlSignature
argument is passed to the worklet in the same order.
For example if we had this worklet:
```cxx
struct DotProduct : public vtkm::worklet::WorkletMapField
{
using ControlSignature = void(FieldIn, FieldIn, FieldOut);
using ExecutionSignature = void(_1, _2, _3);
template <typename T, vtkm::IdComponent Size>
VTKM_EXEC void operator()(const vtkm::Vec<T, Size>& v1,
const vtkm::Vec<T, Size>& v2,
T& outValue) const
{
outValue = vtkm::Dot(v1, v2);
}
};
```
It can be simplified to be:
```cxx
struct DotProduct : public vtkm::worklet::WorkletMapField
{
using ControlSignature = void(FieldIn, FieldIn, FieldOut);
template <typename T, vtkm::IdComponent Size>
VTKM_EXEC void operator()(const vtkm::Vec<T, Size>& v1,
const vtkm::Vec<T, Size>& v2,
T& outValue) const
{
outValue = vtkm::Dot(v1, v2);
}
};
The older Xcode 9 compiler has troubles with ArrayHandleDecorator that
are similar to those of earlier Microsoft and Cuda compilers.
Note that the logic behind the changed compiler check has a lot of
guesswork involved. I noticed this problem on a laptop with Xcode 9
installed. However, even though Xcode uses the clang compiler, it
notoriously does not return the actual clang version. Instead, it
returns some toolchain version that has nothing to do with it. I'm
pretty sure Xcode 9 is using clang version 4 under the covers, but
__clang_major__ reports 9. Oddly, Xcode 10 reports __clang_major__ as 8,
so that's not too much help. So instead, we check for
__apple_build_version__, which returns the Xcode version (sort of) and
that seems a reasonable comparison.
Although I have not tried it, I'm willing to bet that the older clang
outside of Xcode will also have issues. Here is where the real guesswork
takes place since I don't have handy compilers to try. Like I said, I
think the internet claims that Xcode 9 is using clang 4, so also add to
the check any compiler that reports itself clang 4 or below.

The collection of connectivity algorithms had a couple of inefficiencies.
By moving to using WorkId we can remove a couple of arrays of the same size
as the input domain. In addition by moving to using atomics we can remove
an bool output array with a size equivalent to the input domain and
a call to reduce.
The previous implementation of `RuntimeDeviceTracker` occasionally
outputted a log at level `Info` about devices being enabled or disabled.
The problem was that the information given was inconsistent (so it would
sometimes announce one change but not announce a different corrective
change). This could cause weird confusions. For example, when you used a
`ColorTable`, it would use a `ScopedRuntimeDeviceTracker` to temporarily
force the device to `Serial`. The log will just tell you that the device
was forced to `Serial` but never tell you that the devices where
restored to include actual parallel devices.
This change helps correct these with the following changes:
* Added a new log level, `DevicesEnabled`, that is a higher level than
`Info`. All logging from `RuntimeDeviceTracker` goes to this log
level.
* Change the logging output of `RuntimeDeviceTracker` to output a list
of currently enabled devices whenever a change happens. That way you
don't have to guess what happend for each change.
* Change `ScopedRuntimeDeviceTracker` to log whenever the scope is
entered or left.
The tao ones won't compile otherwise. This should be okay, since these
are all just compile time helpers on host-only functions -- they won't
generate different sized data structures etc if we mix them in the
same build.
Previously MeshQuality defined its own SetOutputName method which broke
convention as was confusing. Deleted the output name defined in
MeshQuality and instead use the one defined in the superclass.
The VTK file reader caused an error to be thrown when reading a file
that had a METADATA section at the end of the file. The problem was that
the METADATA section had some whitespace after its last line (which is
probably typical). This caused an eof check to pass and then a
subsequent search for a token to fail.
The solution was to eat the whitespace after the METADATA section to get
the reader at the next token or in eof condition if it is at the end of
the file.
In FilterDataSet::MapFieldOntoOutput, it was getting each field to map
using the traits reserved for the active field. However, when mapping a
field outside of the DoExecute, we want to consider a broader set of
types.

VTK-m now provides the following filters with the default policy
as part of the vtkm_filter library:
- CellAverage
- CleanGrid
- ClipWithField
- ClipWithImplicitFunction
- Contour
- ExternalFaces
- ExtractStructured
- PointAverage
- Threshold
- VectorMagnitude
By building these as a library we hope to provide faster compile
times for consumers of VTK-m when using common configurations.
By leveraging WorkletVisitPointsWithCells we can get already
pre-computed i,j,k locations helping with performance
In addition we have made the algorithm easier to read by
leveraging VTK-m Vec types.

This patch removes (or conditionally removes) the Set method from
portals that are read-only so that IsWritableArrayHandle will work as
expected. The ArrayPortal doxygen has been updated to reflect this.
The remaining exceptions are `ArrayPortalVirtual` and
`ArrayPortalMultiplexer`, since their mutability cannot be determined at
compile time.
