Populate a script with `map_<md5>=<sha512>` variable settings and
then run the following to convert the content link files:

    git ls-files -- '*.md5' | while read f; do
      md5="$(cat "$f")"
      sha512="$(eval echo \${map_$md5})"
      rm "$f"
      echo $sha512 > ${f%.md5}.sha512

Adding in functionality to allow inserting vtkNew objects into
stl containers of vtkSmartPointer objects as well as comparisons
between vtkNew objects and raw pointers. Also removing Get() and
GetPointer() calls from vtkNew objects since in most instances we
can just pass in the vtkNew<> object instead of having to use the
Get() or GetPointer() methods to get the raw pointer.

updating the tests to follow modern standards

CHECK_ERROR_MSG and CHECK_WARNING_MSG are used to check the
content of error and warning messages. Error and warning code is often
overlooked during testing. Over the years, these two macros have been
refined to increase their utility. Tests that use the macros defined
their own interpretations. Three different API's have been used in the
macros.

This patch replaces the CHECK_ERROR_MSG and CHECK_WARNING_MSG macros
with methods for vtkTest::ErrorObserver.  All tests that used the
CHECK macros in one form or another have been updated to use the
CheckErrorMessage and CheckWarningMessage methods.

This commit reindents the code with the following utility:
Utilities/Maintenance/vtk-reindent-code.py

This utility changes the positions of the braces so that they are no
longer indented relative to the code block they reside in.

The bash command line used was the following:

for d in Charts Common Deprecated Domains Examples Filters GUISupport \
         Geovis IO Imaging Infovis Interaction Parallel Rendering \
         Testing Views Web Wrapping; do
  for e in cxx cxx.in txx txx.in hxx hxx.in h h.in c c.in; do
    find "${d}" -name "*.${e}" -exec \
      python Utilities/Maintenance/vtk_reindent_code.py {} +

SafeDownCast performs a series of virtual calls and string comparisons,
which is quite slow, especially when used in worker functions.

vtkArrayDownCast will switch between SafeDownCast and the more
efficient FastDownCast (only available for common vtkAbstractArray
subclasses) depending on whether or not FastDownCast is defined for
the specific array type.

Code extracted from:

    https://gitlab.kitware.com/third-party/proj.git

at commit 41bdf05361007f8c5186f3df9944d86bb273ed13 (for/vtk).

These tests purposefully trigger errors in order to test that they
occur. Use vtkTestErrorObserver to catch these errors rather than
printing them as output and causing the test to fail.

This fix is in response to bug report 0015610. Previously, a named parent node
at the end of a Newick tree would cause vtk to crash.

Combine PhyloXML reader & writer tests into a single test,
and make it more thorough.

Change-Id: Ibb32ece7de203269a8508cb06eee91d94706f197

This class allows us to read a PhyloXML file to generate a
vtkTree.  This commit also contains corresponding change to
vtkPhyloXMLTreeWriter.

Change-Id: Idd7a7a997e24f0c751ee51ee8e2e9eb4c9c05c7a

This commit enables vtkXMLWriter and its subclasses to write
their output to a string instead of a file.

This is an improvement over our previous approach of constructing
the path to the baseilne file from the testing directory.

Change-Id: I2dc0e1354c381ff770475ff2ab7f561b0122e582

Forgot to add the new Baseline directory for IO/Infovis tests.
Hopefully this fixes my failing TestPhyloXMLTreeWriter test.

Change-Id: I153e3b280b27888122d2c09d4eddc18362e6382d

This test now compares its output against a baseline .xml file.

Change-Id: I1e612a1375fc933947228cfa03f16a27aab3bca4

This new class allows us to output vtkTrees in the PhyloXML format.

Modularized TestDataObjectIO to reduce test dependencies.

Enable vtkDelimitedTextReader to take a text string as
the input.

Change-Id: I3d9b8dd0db9dfcd5afd9a6f4bbdc06accd942d94

This class allows us to output vtkTrees in Newick format.

This commit also contains a bug fix for vtkNewickTreeReader.
Before this commit, vtkNewickTreeReader created an extra node at
the root of the tree.  This resulted in the height of the tree and
the number of vertices in the tree both being off by one.

Change-Id: Icd04b2ea868719289be210b34a3f772335b85a27

Adding support to accept a string as the input.
Corresponding test is updated.

Add to the Testing/Data directory ExternalData content links mirroring
the content and layout we use from the VTKData/Data directory.

Add a CMake/vtkLegacyData.cmake module, included from CMakeLists.txt and
Testing/External/CMakeLists.txt, to call ExternalData_Expand_Arguments
for all data directories added from VTKData/Data.  This will bulk-fetch
all test input data currently used by tests of any module, enabled or
not.  We can make the DATA{} references more granular later.

Add a VTK_TEST_DATA_DIR variable to refer to the directory we tell the
ExternalData module to populate the real data files.  Replace references
to VTK_DATA_ROOT in test command lines (after -D) with references to
VTK_TEST_DATA_DIR.  Drop the VTK_DATA_ROOT CMake option and stop using
the VTKData repository.

Remove the TESTING_DATA option from the vtk_add_test_cxx API and remove
the VTK_DATA_ROOT option from the vtk_add_test_mpi API since all test
input data are now handled through ExternalData and Testing/Data content
links.

Tell calls to vtk_add_test_(cxx|python|tcl) explicitly when there is no
valid baseline image to avoid passing -V unnecessarily.

Change-Id: Ibe5aecdfa076446ddda0b95e814483eb6622af73

Refactor */*/Testing/Cxx/CMakeLists.txt to use the vtk_add_test_cxx
function instead of direct add_test calls.

Change-Id: I73dee627fa87a399c48b409af046b116fc75a0fd

The vtkTestingInteractor was trying to run regression tests even if
VTK_DATA_ROOT was not defined.

Many Testing/Cxx CMakeLists.txt files tried to run tests that required
input data, even though VTK_DATA_ROOT was not defined.

Subsequent topics will address Tcl and Python tests.

vtkMultiNewickTreeReader internally uses vtkNewickTreeReader to read

are saperated by ";".

Replace all references to ${VTK_BINARY_DIR}/Testing/Temporary with
${VTK_TEST_OUTPUT_DIR} and set the variable accordingly.  The latter is
shorter and will also be useful to build module tests as an external
application that does not have VTK_BINARY_DIR available.

Add module.cmake, CMakeLists.txt, and other build system files.

The modular VTK build system is not yet mature.  The monolithic build
files had a lot of infrastructure.  The modular build files reproduce
much of the functionality but some features will need to be restored
later.  Document status and tasks in "TODO-Modularization.txt".

Move source files from their former monolithic VTK location to their new
location in modular VTK without modification.  This preserves enough
information for "git blame -M" and "git log --follow" to connect
modularized VTK files to their original location and history.
