Add-ons may attempt to load the GPU module in background mode when no GPU
context has been initialized yet. This would give an error on import.
If then later the GPU context does get initialized, for example for a
render engine, import would still fail as the module is cached.
This reverts commit d7f124f06f, and again
throws errors in methods and constructors instead of module import.
Pull Request: https://projects.blender.org/blender/blender/pulls/123395
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.
