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.
These are meant to test Hydra integration. Currently they are only enabled
for WITH_OPENGL_RENDER_TESTS=ON due to similar reasons as Eevee and
Workbench, which is that they require a GPU and results can be platform
dependent due to hardware and driver differences.
There are separate tests for USD and Hydra export paths. The goal is to
make these identical, but they aren't yet. So for that reason they have
separate reference renders, and there is a HTML page to compare them.
