While \file doesn't need an argument, it can't have another doxy
command after it.

Move \ingroup onto same line to be more compact and
make it clear the file is in the group.

Needed for clan-format not to wrap onto one line.

BF-admins agree to remove header information that isn't useful,
to reduce noise.
- BEGIN/END license blocks
Developers should add non license comments as separate comment blocks.
No need for separator text.
- Contributors
This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.

Brecht authored this commit, but he gave me the honours to actually
do it. Here it goes; Blender Internal. Bye bye, you did great!
* Point density, voxel data, ocean, environment map textures were removed,
as these only worked within BI rendering. Note that the ocean modifier
and the Cycles point density shader node continue to work.
* Dynamic paint using material shading was removed, as this only worked
with BI. If we ever wanted to support this again probably it should go
through the baking API.
* GPU shader export through the Python API was removed. This only worked
for the old BI GLSL shaders, which no longer exists. Doing something
similar for Eevee would be significantly more complicated because it
uses a lot of multiplass rendering and logic outside the shader, it's
probably impractical.
* Collada material import / export code is mostly gone, as it only worked
for BI materials. We need to add Cycles / Eevee material support at some
point.
* The mesh noise operator was removed since it only worked with BI
material texture slots. A displacement modifier can be used instead.
* The delete texture paint slot operator was removed since it only worked
for BI material texture slots. Could be added back with node support.
* Not all legacy viewport features are supported in the new viewport, but
their code was removed. If we need to bring anything back we can look at
older git revisions.
* There is some legacy viewport code that I could not remove yet, and some
that I probably missed.
* Shader node execution code was left mostly intact, even though it is not
used anywhere now. We may eventually use this to replace the texture
nodes with Cycles / Eevee shader nodes.
* The Cycles Bake panel now includes settings for baking multires normal
and displacement maps. The underlying code needs to be merged properly,
and we plan to add back support for multires AO baking and add support
to Cycles baking for features like vertex color, displacement, and other
missing baking features.
* This commit removes DNA and the Python API for BI material, lamp, world
and scene settings. This breaks a lot of addons.
* There is more DNA that can be removed or renamed, where Cycles or Eevee
are reusing some old BI properties but the names are not really correct
anymore.
* Texture slots for materials, lamps and world were removed. They remain
for brushes, particles and freestyle linestyles.
* 'BLENDER_RENDER' remains in the COMPAT_ENGINES of UI panels. Cycles and
other renderers use this to find all panels to show, minus a few panels
that they have their own replacement for.

coverity).
Error: `origin` and `edge` args were swapped in final `FindOccludee()` call of `ViewMapBuilder::ComputeRayCastingVisibility()`
Cleanup: main for loop in `Strip::createStrip()` was really confusing (though correct),
generated a false positive in coverity scan, now should be cleaner how it loops over its vprev/v/v2
triplet of consecutive items.

(A - A).norm() is always 0 so condition is always true.
(A - B).norm() and (B - A).norm() both compute the same distance so I
picked one to match surrounding code.

The reported crash was confirmed as a segmentation fault in std::sort().
The cause of the crash was traced down to a binary comparison function
that was not satisfying the so-called strict weak ordering requirements of
the C++ standard sorting function. Specifically, the comparison operator
has to return false when two objects are equivalent (i.e., comp(a, a) must
be false), but that requirement was not met.
Since the binary comparison operator in question could be a user-defined
Python function, here a safety measure is implemented in the C++ layer to
make sure the aforementioned requirement is always satisfied.

Also fixed a potential crash in the copy constructor case.

ImBuf types were getting stored as bitflags in a 32bit integer which had
already run out of space. Solved the problem by separating file type to
an ftype enum, and file specific options to foptions.

This patch introduces a couple new stroke modifiers. The ones currently implemented are based on prototypes by @kjym3 and myself.
The new modifiers:
- Tangent
- Thickness noise
- Crease Angle
- Simplification
- Curvature 3D
The documentation for these new modifier types can be found [[ http://www.blender.org/manual/render/freestyle/parameter_editor/index.html | in the manual ]]:

The reported problem was due to a special case where there are no strokes
to be rendered. Since rendering an empty scene is a waste of time, the issue
was addressed here by skipping the stroke rendering process entirely.
|
|
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.
|
|
Do not know why this shows up now, probably a recent tweak in BLI_utildefines.h or so...

This patch removes several stroke shaders written in C++ that are unused
and don't serve a real purpose any more. The removed shaders are:
- BPy_ColorVariationPatternShader
- BPy_StrokeTextureShader
- BPy_TextureAssignerShader
- BPy_ThicknessVariationPatternShader
- BPy_fstreamShader
- BPy_streamShader
and a few more that weren't even exposed to the Python API.
Some minor edits were made by the reviewer.

operations.
The view map is mostly treated as a read-only data structure by line stylization
operations (i.e., selection, chaining, splitting, sorting and stroke creation). The
only exception is the chaining operation in some cases where insertion of extra
FEdge objects is necessary to ensure the continuity of underlying FEdges from
which a chain is constructed.
The present revision addresses the removal of extra FEdges so to keep the view
map clean and suitable for reuse in subsequent render frames.

The Operators.reset function is exposed to the Freestyle Python API, which makes
it possible to combine multiple style modules into one file.

The problem addressed here is that there was no mean to check if an iterator
points the last of the elements being iterated over. Such checking is necessary
to reliably dereference the iterator (i.e., calling the operator*() method of the
underlying C++ iterator object).
Now Interface0DIterator and StrokeVertexIterator have an .at_last property
to check if an iterator points the last element. Using this new API feature,
the present commit partly reverts the previous commit rBeb8964fb7f19 to
better address T41464.

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.
