Now that the dispatcher does its own TryExecute, filters do not need to
do that. This change requires all worklets called by filters to be able
to execute without knowing the device a priori.
It's a filter that Split sharp manifold edges where the feature angle
between the adjacent surfaces are larger than the threshold value.
When an edge is split, it would add a new point to the coordinates
and update the connectivity of an adjacent surface.
Ex. there are two adjacent triangles(0,1,2) and (2,1,3). Edge (1,2) needs
to be split. Two new points 4(duplication of point 1) an 5(duplication of point 2)
would be added and the later triangle's connectivity would be changed
to (5,4,3).
By default, all old point's fields would be copied to the new point.
Use with caution.
This commit adds a worklet as well as a filter that modify point coordinates by moving points
along point normals by the scalar amount times the scalar factor.
It's a simpified version of the vtkWarpScalar class in VTK. Additionally the filter doesn't
modify the point coordinates, but creates a new point coordinates that have been warped.

This commit adds a worklet and a filter to compute
signed integral measures of cells.
It also begins the practic of adding a markdown
changelog entry in `doc/changelog`. See the
changelog entry for details.
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 commit removes `vtkm::filter::Result`. All methods that used
`vtkm::filter::Result` simply change to use `vtkm::cont::Dataset` instead.
The utility API on `Result` that was used to add fields to the resulting
dataset is now available via `vtkm::filter::internal::CreateResult`.
The problem is that there is no good "default" constructor for
ColorTable. The previous default constructor created an empty color
table, but that would be confusing if someone actually tried to use it.
We could set ot to the default preset, but the default preset uses the
diverging color map, which could foul people up if they actually want to
edit or create their own color map. Instead, force the declaration of
ColorTable to indicate what you plan to do with it.
You can still select presets through strings (and we leave ourselves
open to add more presets through strings than enumerating with the
enum), but this provides a way to select a preset that is verified by
the compiler.
Both the dot product filter and the cross product filter require 2
fields to be selected as their input. Previously, you used the
superclass' SetActiveField for the primary field and
SetSecondaryFieldName for the secondary field. This changes adds a
SetPrimaryField method to make the selection more clear. I also changed
SetSecondaryFieldName to SetSecondaryField that optionally takes an
association to make it more consistent.
The first convenience method takes a FieldSelection and a mode. The mode
given will override the mode in the FieldSelection. The intention is to
make it easy to give the constructor argument for FieldSelection and the
mode. For example, if you wanted to pass all variables _except_
"stopfield", you could say
field.SetFieldsToPass("stopfield",
vtkm::filter::FieldSelection::MODE_EXCLUDE);
I also added a convenience method that takes the name of a field and an
association.
field.SetFieldsToPass("pointfield",
vtkm::cont::Field::ASSOC_POINTS);
Granted, you could get the same effect by wrapping this arguments in
initializer braces, but this is a bit more clear.
Previously you passed a FieldSelection to Filter::Execute to specify
which fields to pass from input to output. There is no real reason for
this as other information about input and output fields are member
variables to Filter. This moves field selection as a member variable as
well. (This should also help confusion when updating old code to new to
prevent users from mistaking field passing with input fields.
Also added a few convenience constructors to FieldSelection so that you
can call Field::SetFieldsToPass() with just the string of what you want
to pass.
This allows you to turn off the selection of fields rather than turn
them on. It could be helpful, for example, if you were isosurfacing on a
single isovalue and didn't want to pass the field you are contouring on
(because it's all the same value).
This mode forces the selection to be empty. Although there is no
practical difference between having MODE_NONE and having MODE_SELECTED
with nothing selected (which is the default), this is a semantically
nicer way to say you don't want any fields.
Since we have changed the default behavior of Filter::Execute to be
MODE_ALL, this is a nice addition so that you can clearly specify you
don't want to pass any fields by adding
vtkm::filter::FieldSelection::MODE_NONE as the second argument. (Making
it MODE_SELECTED is not clear that you want none.)
This avoid accidental conversions from DataSet to Result in return
values. This exposed several issues with filters and their tests. Fixed
those as well.

Filters now support executing on a dataset to produce a result dataset
with automatic mapping of fields to the output dataset. Fields to map
can be selected using `vtkm::filter::FieldSelection` class, which provides
constructors to map all or no fields, along with a selection of fields.
This updates all tests to use the new filter API.
