This is a regression introduced in rBce729677db3e and rBb408d8af31c9.
RoundCapShader and SquareCapsShader had to remove (almost) overlapping
stroke vertices to avoid sudden thinning of line thickness. For instance,
the test .blend file from https://developer.blender.org/T36425#231460
suffered from the reported line thinning (although T36425 was originally
caused by a different bug).
This patch adds some new functionality to the Freestyle Python API, notably:
- MaterialBP1D, checks whether the supplied arguments have the same material
- Fixes a potential crash in CurvePoint.fedge (due to NULL pointer)
- Makes (error handling in) boolean predicates more robust
- Adds a BoundingBox type, to make working with bounding boxes easier
- Adds several new functions (get_object_name, get_strokes, is_poly_clockwise, material_from_fedge)
- Adds a StrokeCollector StrokeShader, that collects all the strokes from a specific call to Operators.create()
- Adds hashing and rich comparison to the FrsMaterial type
These new features (most of them, anyway) are needed for making a more robust SVG exporter that supports holes in fills.

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.

Freestyle sections of the API docs were empty due to Freestyle module reorganization
in commit rB6498b96ce7081db039354228213d72e8c70bd3aa.
Module __all__ property was added to submodules so as to properly exclude irrelevant
documentation elements such as mathutils.Vector.
This revision is meant to update Freestyle's Python scripts to make full usage
of the new features of Python and Freestyle's Python API.
Freestyle's Python scripts are pretty old already, and were never given much
attention. With the 2.7x generation of Blender coming up, this is an excellent
time to update Freestyle's Python scripts, hopefully adding some new features
and achieving some speed improvements on the way.
Main goals:
* use for loops where possible
* general cleanup, making use of more recent python features (generators,
ternary operator, ect.)
* update the documentation on the way (it's lacking atm)

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.
Both C- and Python-coded API components were rearranged into logical groups.
New Python modules are packaged as follows:
freestyle - Top-level package
freestyle.types - Classes for core data structues (e.g., view map)
freestyle.chainingiterators - Pre-defined chaining iterators
freestyle.functions - Pre-defined 0D and 1D functions
freestyle.predicates - Pre-defined 0D and 1D predicates
freestyle.shaders - Pre-defined stroke shaders
freestyle.utils - Utility functions
The Python modules are installed in scripts/freestyle/modules. Pre-defined
styles are installed in scripts/freestyle/styles.
To-do: update styles according to the new Freestyle API package structure.
