- fixes undeclared name error with GCC 13.3.1 used in fedora39 runners.

From the image, it looks like the unit test read two input files.
However, the unit test code doesn't actually read any data files.
Instead, it programmatically generates two vtkImageData. I think
the baseline was accidentally checked in and the regression test
logic failed to detect the error.

Also, the test has been fixed to assign all components to avoid
random value initialization.

- the link options are now centralized in the `VTK::vtkWebAssemblyTestLinkOptions` target with `INTERFACE` visibility.
- this leverages the fact that all unit tests link with the `VTK::TestingCore` library.
- On emscripten platform, the asyncify link options are separately appended on the vtkRenderingWebGPUCxxTests target.

Add support for setting multiple constant values for use with
mappers which support manipulating multiple textures.

Ben Boeckel authored 3 months ago and Spiros Tsalikis committed 3 months ago

When SSIM returns a negative value, the histogram bucketing ends up
writing to out-of-bounds memory. Don't do that and instead shift the
buckets to account for the full range of values that are possible.

Finally, add commentary on the code.

The clamping is still preserved as enabled by default in vtkTesting,
because we want to treat the anti-correlated images (negative values)
in the same way as not similar.

- dynamically construct the arguments for
  recognized engines, like chrome/chromium.

When an operation supports only 1 input, but many inputs have
been provided, we make sure that only the first is used.

Also add anonymous namespace

For some reason the baselines are slightly different on macos.

Remove the threshold that existed before because
the new image testing framework is now used, whose
threshold ranges from 0 to 1, and 0.05 is a good default.

- this fixes flakiness in couple unit tests due to a spurious error that occurred when creating extra threads https://github.com/emscripten-core/emscripten/issues/12223 by completely disabling threads for unit tests.
- sync XHR in `vtkPreloadDataFileIntoMemory` is apparently possible when the mimetype is `text/plain` - https://stackoverflow.com/a/63920556/7102809
- Now, `vtkEmscripten.cmake` does not enable threads by default when `VTK_BUILD_TESTING` is `WANT` or `ON`.
- Make `VTK_USE_PTHREADS` honor the value of `VTK_WEBASSEMBLY_THREADS`. This correctly configures code in VTK which assumes pthreads exist.
- Remove pthread proxying and offscreen canvas link flags from unit tests as they're no longer required.

Indexing into a multi-component image, the pointer was walking an
additional step using the scalar size. Since, the pointer is templated
over the underlying type, indexing directly into the active component
yields the right result.

Rework vtkImageSSIM mode logic to separate an explicit automatic mode (default)
from a new MODE_INPUT_RANGE. MODE_NONE has been removed.

When an input vtkImageData did not contain point scalars (e.g., because it contains tensors, or no point data at all) then vtkImageReslice crashed.
It is not a problem if the filter only processes scalar data, but it should never crash, for any kind of input data.

- enablesr Rendering{Core, OpenGL}CxxTests in browser with vtk.wasm.
- upgrades to CI can be found in the next commit.
- all C++ tests are run with a python script Testing/WebAssembly/runner.py. This script coordinates the entire wasm testing process.
- the runner.py script generates a html file per unit test at runtime, serves the html, js and wasm files with a http server and opens the URL in a browser. It implements some usefule POST/GET actions which enable C++ tests to preload/dump files and forward stdout/stderr/exit codes to the python process.
- this commit introduces vtkEmscriptenTestUtilities which can load data files and baseline images required by a c++ unit test from a browser sandbox.
