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.

* DRW Instance Data Manager

* This is a special memory manager that keeps memory blocks ready to send as VBO data in one
|
|
* continuous allocation. This way we avoid feeding #GPUBatch each instance data one by one and
|
|
* unnecessary memcpy. Since we lose which memory block was used each #DRWShadingGroup we need to
|
|
* redistribute them in the same order/size to avoid to realloc each frame. This is why
|
|
* #DRWInstanceDatas are sorted in a list for each different data size.
