Listing the "Blender Foundation" as copyright holder implied the Blender
Foundation holds copyright to files which may include work from many
developers.
While keeping copyright on headers makes sense for isolated libraries,
Blender's own code may be refactored or moved between files in a way
that makes the per file copyright holders less meaningful.
Copyright references to the "Blender Foundation" have been replaced with
"Blender Authors", with the exception of `./extern/` since these this
contains libraries which are more isolated, any changed to license
headers there can be handled on a case-by-case basis.
Some directories in `./intern/` have also been excluded:
- `./intern/cycles/` it's own `AUTHORS` file is planned.
- `./intern/opensubdiv/`.
An "AUTHORS" file has been added, using the chromium projects authors
file as a template.
Design task: #110784
Ref !110783.
Recent failures requiring investigation have exposed some shortcomings
that this addresses:
- When creating the diff image for offline comparison, use a higher
threshold to prevent idiff from printing more output which will often
contradict the primary failure output just above it (very confusing)
- For metadata failures, make sure these get printed so it's obvious
what kind of failure we're dealing with

This checkin will use OIIO to replace the image save/load code for BMP,
DDS, DPX, HDR, PNG, TGA, and TIFF.
This simplifies our build environment, reduces binary duplication,
removes large amounts of hard to maintain code, and fixes some bugs
along the way.
It should also help reduce rare differences between Blender and Cycles
which already uses OIIO for most situations. Or potentially makes them
easier to solve once discovered.
This is a continuation of the work for #101413

This adds saving and loading tests for our supported image formats.
**Saving - bf_imbuf_save.py**
There are 2 template images which are loaded anew for each file save
attempt. One is an 8-bit RGBA image and the other 32-bit. This is
required as many formats use a variety of factors to determine which of
`ibuf->rect` or `ibuf->rectfloat` to use for processing. The templates
are constructed to have alpha transparency as well as values > 1 (or
clamped to 1 for the case of the 8-bit template).
Test flow:
- Load in an appropriate template image
- Save it to the desired format with the desired set of options
- Compare against the reference image
Notes:
- 98 references are used totaling ~3.6MB
- 10-12 second test runtime
- Templates can be reconstructed with the create-templates.blend file
**Loading - bf_imbuf_load.py**
Test flow:
- Load in each of the reference images
- Save them back out as .exr
- Save additional metadata to a secondary file (alpha mode, colorspace etc)
- Compare the saved out .exr with another set of reference .exrs
- Compare the saved out file metadata with set of reference metadata
Notes:
- 98 exr references are used totaling ~10MB
- 10-12 second test runtime as well
A HTML report is not implemented. The diff output organization is very
similar to the other tests so it should be somewhat easy to do in the
future if we want.
The standard set of environment variables are implemented for both:
BLENDER_TEST_UPDATE, BLENDER_VERBOSE, and BLENDER_TEST_COLOR
