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.

File headers: SPDX License migration Use a shorter/simpler license convention, stops the header taking so much space. Follow the SPDX license specification: https://spdx.org/licenses - C/C++/objc/objc++ - Python - Shell Scripts - CMake, GNUmakefile While most of the source tree has been included - `./extern/` was left out. - `./intern/cycles` & `./intern/atomic` are also excluded because they use different header conventions. doc/license/SPDX-license-identifiers.txt has been added to list SPDX all used identifiers.

Freestyle Python API improvements - part 9. * Fix for wild card import statements (e.g., "from Freestyle import ") was done. Now import statements are either without using "from" or with all imported names explicitly listed. GNU GPL header blocks were added to Python programs. Additional code clean-up was also made. * Removed freestyle_init.py and extra-lines.sml that were no longer used. 2013-02-24 23:43:40 +00:00			`# Author : Stephane Grabli`

Updated Freestyle API modules according to the new hierarchical package structure. Additional bug fixes were also done along with the code updates: * Fix for the use of old Interface1D.pointsBegin() and .pointsEnd() method names in the definition of pyDensityAnisotropyF1D and pyViewMapGradientNormF1D. * Fix for wrong data types (int instead of bool) for: - pyChainSilhouetteGenericIterator constructor and its .orientation property in modules/freestyle/chainingiterators.py. - SpatialNoiseShader constructor in styles/external_contour_sketchy.py. - ChainSilhouetteIterator constructor in styles/multiple_parameterization.py. 2013-11-24 22:18:38 +00:00			`from freestyle.chainingiterators import ChainPredicateIterator`

Freestyle Python API improvements - part 8. * Proper handling of keyword arguments was implemented in Operators and ContextFunctions, as well as in methods of Interface0D, Interface1D, Iterator, their subclasses, Noise and IntegrationType. * Operators' methods and functions in the ContextFunctions module were renamed from CamelCase to lower cases + underscores. Style modules were updated accordingly. * Additional code clean-up was also made. 2013-02-24 02:39:38 +00:00			`Operators.bidirectional_chain(ChainPredicateIterator(upred, bpred), NotUP1D(QuantitativeInvisibilityUP1D(0)))`
