Zijun Zhou a9053f7efb Color management: Add AgX view transform and make it default
On a user level this view transform provides much better handling of colors in
the over-exposed areas.

With this configuration the following display devices are available, including
AgX view transform for them:
* sRGB
* Display P3
* Rec.1886
* Rec.2020

NOTE: There is no Filmic view transform available for the newly added display
devices.

AgX also brings an implementation of False Colors view transform, which replaces
Filmic-based, and is available for all display devices.

The backward compatibility is preserved. The new files will default to AgX view
transform, which makes it non-forward compatible.

More technical details is available in the original PR #106355.
Please note that the PR has been split into more incremental changes when
was landing.

Campbell Barton e955c94ed3 License Headers: Set copyright to "Blender Authors", add AUTHORS
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.

Jesse Yurkovich aa3bdfd76a Image: Use OpenImageIO for loading and saving a variety of image formats
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

Jesse Yurkovich 2d34a09043 Tests: Address imbuf_save failures on ARM64 builds
This does 2 things to address the ARM64 failures:
- Increases the threshold to be inline with what Cycles uses
- Disables the 2 problematic WebP variations (#105006 will track)

Jesse Yurkovich 7699c7407d Tests: Add tests for image format saving and loading
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
