This tool uses existing libraries: image, imageio, imageio-lite,
imagediff to perform difference comparison for on-disk images.
We refactor renderdiff to use this tool instead of using
python dependencies.

- Make sure that renderdiff fails when either building or
rendering fails (the previous problem was in the use of &&
that masked the non-zero exit).
- Make sure that golden branch is properly parsed in
postsubmit.yml
- Disable vk loader debug by default
WebGPU's rendering of bloom sems to be non-deterministic. This
is not expected. For now, we disable bloom+webgpu to avoid
hitting flakes in our CI.
This required a slight refactoring of the test configuration
parsing and execution scripts.

- --no_rebuild will skip building the gltf_viewer again
- --num_threads will limit the number of threads used in running
the rendering test.
Both of these options are meant for debugging locally.
- Allow for presets to override selected models when presented
in order.
- Add 'gltf' for model search path
- Add a few simple gltf models to the 'base' preset
- Improve UI so that missing tests do not generate any html
bits.
- Add documentation on using the viewer
- Add renderdiff documentation to the project webpage.
RDIFF_BRANCH=pf/renderdiff-enable-webgpu
- Modify the compare script to output more details of a
comparison. This will include the source/golden directory,
the comparison directory (the new renderings), and a file
path to difference images if the golden does not match
the rendered image.
- The image_diff script can now output a TIFF that is the
difference of two input TIFFs.
- Add a viewer for examining the differences between rendered
output and golden images.
- The viewer consists of a simple server of web API endpoints
for querying difference results (along with rendered images
in TIFF).
- And a web-based (html + lit-element) UI for looking at the
rendered images and differences.
- Move the comparison logic into its own script
- Add entry point bash script to generate the renderings
- Separate the preamble bash logic into its own file
