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.

Cleanup: Add a copyright notice to files and use SPDX format A lot of files were missing copyright field in the header and the Blender Foundation contributed to them in a sense of bug fixing and general maintenance. This change makes it explicit that those files are at least partially copyrighted by the Blender Foundation. Note that this does not make it so the Blender Foundation is the only holder of the copyright in those files, and developers who do not have a signed contract with the foundation still hold the copyright as well. Another aspect of this change is using SPDX format for the header. We already used it for the license specification, and now we state it for the copyright as well, following the FAQ: https://reuse.software/faq/

Keying Screen node from tomato branch Merge Keying Screen node developed in tomato branch into trunk. This node is aimed to make dealing with non-even greenscreens better by generating gradiented image which could be used a input for keyer nodes. Based on building voronoi diagram using motion tracking markers as sites position and average pattern color as color for that site. Pretty straignforward node, some documentation is there http://wiki.blender.org/index.php/User:Nazg-gul/Keying#Screen_color

Compositor: Use RBF Interpolation in Keying Screen node This patch changes the interpolation algorithm utilized by the Keying Screen node to a Gaussian Radial Basis Function Interpolation. This is proposed because the current Voronoi triangulation based interpolation has the following properties: - Not temporally stable since the triangulation can abruptly change as tracking markers change position. - Not smooth in the mathematical sense, which is also readily visible in the artists sense. - Computationally expensive due to the triangulation and naive rasterization algorithm. On the other hand, the RBF interpolation method is temporally stable and continuous, smooth and infinitely differentiable, and relatively simple to compute assuming low number of markers, which is typically the case for keying screen objects. This breaks backward compatibility, but the keying screen is only used as a secondary input for keying in typical compositor setups, so one should expect minimal difference in outputs.
