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.
See: https://projects.blender.org/blender/blender/issues/103343
Changes:
1. Added `BKE_node.hh` file. New file includes old one.
2. Functions moved to new file. Redundant `(void)`, `struct` are removed.
3. All cpp includes replaced from `.h` on `.hh`.
4. Everything in `BKE_node.hh` is on `blender::bke` namespace.
5. All implementation functions moved in namespace.
6. Function names (`BKE_node_*`) changed to `blender::bke::node_*`.
7. `eNodeSizePreset` now is a class, with renamed items.

Use a shorter/simpler license convention, stops the header taking so
much space.
Follow the SPDX license specification: https://spdx.org/licenses

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.

Previously individual strokes were represented by distinct mesh objects
no matter how many vertices and materials each stroke has, although
the vertex and material counts can be quite small depending on the input
scene data. Now stroke meshes are packed into a minimum number of
mesh objects, so as to reduce the overheads of Blender object creation.
Removed the previous changes for passing a line style through the Controller, and
revised the BlenderTextureShader to assign the shader node tree of a line style
(if specified) to strokes. This way the assignment of shading nodes can be done
through both the Freestyle GUI and Python scripting.
Now the shader node tree of a line style ID datablock is used to define textures
as well as their mapping and influence.
TODO: Textures alpha channel mapping and influence.
TODO: Blend mode in the Output Line Style shader node.
Changes were made in Stroke::Resample(int) in C++ to prevent a potential infinite loop
caused by an inconsistency between Stroke::_Length and the stroke length computed
based on stroke vertices. Such a stroke length inconsistency is usually caused by missing
calls of Stroke::UpdateLength() (i.e., API implementation bugs), but also may occur due
to scripting errors in user-defined style modules. This commit is meant to help script
writters to identify the latter error cases. Now Stroke.resample(int) may raise a runtime
error to signal an error condition.
A crash in the Freestyle renderer was reported by Ton on IRC with a stack trace
below. Note that #2 is in Freestyle, whereas #1 is in the compositor. The problem
was observed in a debug build on OS X 10.7 (gcc 4.2, openmp disabled, no llvm).

Apparently a name conflict between the two Blender modules is taking place.
The present commit hence intends to address it by putting all the Freestyle C++
classes in the namespace 'Freestyle'. This revision will also prevent potential
name conflicts with other Blender modules in the future.
Special thanks to Lukas Toenne for the help with C++ namespace.
StrokeVertex.point2d() instead of .getPoint(). It is noted that .point2d()
returns a 3-dimensional vector representing a 2D-projected point, with the z
component indicating a normalized depth of the original 3D point, whereas
.getPoint() returns a plain 2-dimensional vector. This fix should have been
done in revision 48510...
Also made fix for callers of Stroke.Resample() not calling stroke.UpdateLength().
on the console during Freestyle rendering. The debug prints are turned off
by default now. Errors are still printed on the console.
A patch set implementing this functionality was provided by Bastien Montagne.
Many thanks! :)
The Post Processing tab in the Render buttons has new Line Thickness options for
defining unit line thickness in two different modes as follows:
1. Absolute mode: The unit line thickness is given by a user-specified number
in units of pixels. The default value is 1.
2. Relative mode: The unit line thickness is scaled by the proportion of the
present vertical image resolution to 480 pixels. For instance, the unit line
thickness is 1 with the image height set to 480, 1.5 with 720, and 2 with 960.
* Stroke::Resample(int nPoints) was not properly working when a wrong
value was returned from Stroke::getLength2D(), resulting in repeated
warning messages "Warning: incorrect points number" during stroke
rendering. The main cause was that stroke geometry shaders did not
update the two-dimensional (2D) length (also referred to as curvilinear
abscissa) after they modified the 2D points of stroke vertices. Now
all stroke geometry shaders make explicit calls for Stroke::UpdateLength()
that has been introduced for recomputing the 2D length. Many thanks to
Josef who reported the problem together with sample .blend files for
reproducing the issue.
* Missing Python wrapper of Stroke::getLength2D() was added.
