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.

* It is used to access each component data such as matrices and object attributes.
|
|
* It is valid only for the current draw, it is not persistent.
|
|
*
|
|
* The most significant bit is used to encode if the object needs to invert the front face winding
|
|
* because of its object matrix handedness. This is handy because this means sorting inside
|

* #DrawGroup command will put all inverted commands last.
|
|

|

* Default value of 0 points toward an non-cull-able object with unit bounding box centered at
