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. See P2788 for the script that automated these edits. Reviewed By: brecht, mont29, sergey Ref D14069

# Purpose : The thickness and the color of the strokes vary continuously
|
|
# independently from occlusions although only
|
|
# visible lines are actually drawn. This is equivalent
|
|
# to assigning the thickness using a parameterization covering
|
|
# the complete silhouette (visible+invisible) and drawing
|
|
# the strokes using a second parameterization that only
|
|
# covers the visible portions.
