Added a set of stroke geometry modifiers to the Geometry tab of line styles
in the Parameter Editor mode. Now the following stroke geometry modifiers are
available, each with a set of animateable parameters:
- Sampling: changes the resolution of stroke backbone polylines.
- Bezier Curve: replace stroke backbone with a Bezier approximation of the
stroke backbone.
- Sinus Displacement: add sinus displacement to stroke backbone.
- Spatial Noise: add spatial noise to stroke backbone.
- Perlin Noise 1D: add one-dimensional Perlin noise to stroke backbone.
- Perlin Noise 2D: add two-dimensional Perlin noise to stroke backbone.
- Backbone Stretcher: stretch the beginning and the end of strokes.
- Tip Remover: remove a piece of stroke at the beginning and the end of strokes.
To branch users: When you have a .blend file with Freestyle options specified,
you may want to add a Sampling modifier with the 'sampling' value set to 5.
This value specifies a resolution of polylines for line drawing in Freestyle.
If no sampling modifier is specified, your line drawing will result in coarse
polylines. Before geometry modifiers were introduced, this initial sampling
was automatically done. Now the initial sampling is a tunable parameter that
can be omitted, allowing better control on polyline resolution.

or greater than zero; otherwise, time is used as a seed.

occasional unexpected long lines.
1. The Parameter Editor mode was extended to prevent strokes from
doing quick U-turns that "enable" a known bug in strip creation
that generates unexpected long lines in question.
2. A verbose warning message was added to make the existence of
the strip creation bug visible to users. When the bug affects the
stroke rendering, the following warning shows up in the console:
> Warning: problem in strip creation (the strip is most likely doing a U-turn).
3. The extrapolation option of CurveMapping (used in alpha and
thickness modifiers in the Parameter Editor mode) was identified
as another source of unexpected long lines. Now the extrapolation
option is unconditionally disabled (even when users enable it
through the GUI).

The bug was reported by Jonathan Hudson, thanks!

* Made changes to the Controller so that dynamically allocated
memory areas (e.g. imported mesh data, winged edges, and a view map)
are released soon after they become unnecessary.
* Added a new feature edge selection criterion based on image border.
When the "Selection by Image Border" option is enabled, feature edges
are selected only if they are within the border of the image being
rendered. The border is defined either by the frame size or a border
region (specified by the Shift-B key in a 3D View window). When large
scenes are rendered, this clipping by the image border leads to less
memory consumption.
* Enabled the "Silhouette", "Border", and "Crease" edge types of
the Selection by Edge Types option by default.
When no edge types are specified, all feature edges including "Ridge",
"Valley" and "Suggestive Contour" are detected at the cost of extra
memory consumption. Disabling these three edge types and enabling
some other edge type leads to less memory consumption. This change
is intended to help new Freestyle users by providing a typical, low
memory consumption default setting.
* Slightly rearranged the UI controls for feature edge selection.

The Freestyle tab in the Render buttons has a couple of new
options "Group" and "Group Negation". The Group option specifies
a group of objects (defined through the Groups tab in the Object
buttons), while the Group Negation value is either INCLUSIVE or
EXCLUSIVE. If INCLUSIVE, feature edges belonging to some object
in the group are selected. Otherwise, those feature edges not
belonging to any object in the group are selected.

of both ends of strokes. The three cap types are: 1) butt caps (flat);
2) round caps (half-circle); and 3) square caps (flat and extended).
Also implemented an option to join those feature edges of the same
object. These options are available in the "Stroke" tab of the
"Freestyle: Line Style" panel in the Render buttons.

Parameter Editor mode. This is a WIP commit. Only the base line
color, base alpha transparency, and base line thickness are respected.
More additions are anticipated to account for other parameters.
* Added FRS_finish_stroke_rendering() to clean Freestyle-related
temporary resources after stroke rendering.
* Some functions in FRS_freestyle.cpp are now declared as static
functions, so as not to mess up the program-wide name space.
* Made the StyleModule class inheritable, and defined new subclass
BlenderStyleModule that takes a Text object instead of a file name.

* Fixes for Vector instantiation that now takes only a sequence object of
2, 3, or 4 elements -- an API change in revision 28417.
* Deleted vector.py that is no longer used.

the Freestyle module, so that there is no need to make their names
globally unique.

This allows users to test the types of those objects that are returned
by API functions, by means of usual Python idioms such as "type(I) is T"
and "isinstance(I, T)".
* Removed all occurrences of ViewVertex::castToTVertex() in the following
modules and rewrote the code segments using it by means of the "type(I)
is T" idiom mentioned above:
ChainingIterators.py
PredicatesU1D.py
* Replaced all occurrences of vector.Vec2, vector.Vec3, Vec2f and Vec3f
by Blender.Mathutils.Vector in the following modules:
anisotropic_diffusion.py
Functions0D.py
shaders.py
sketchy_topology_broken.py
* shaders.py: Fixed NameError's concerning math.pow().
* shaders.py: Added a Python equivalent of getFEdge function, defined
in source\blender\freestyle\intern\view_map\Functions0D.cpp as follows:
FEdge* Functions0D::getFEdge(Interface0D& it1, Interface0D& it2) {
return it1.getFEdge(it2);
}
* shaders.py: Replaced fe.qi() by fe.viewedge().qi().
* contour.py: Fixed the import statement for freestyle_init.py.

* Added a generic getName() method that allows subclasses to omit the method to return their class names.
BPy_Convert.cpp
BPy_Convert.h
* Added to BPy_StrokeVertexIterator_from_StrokeVertexIterator() a second argument to specify the direction (reversed or not) of the iterator to be created.
BPy_Stroke.cpp
* Added support for Python's native iterator protocol.
* Added code to parse the optional argument of strokeVerticesBegin().
BPy_StrokeVertexIterator.cpp
BPy_StrokeVertexIterator.h
* Added support for Python's native iterator protocol.
Stroke.cpp
* Fixed a null pointer reference.
Stroke.h
* Added new method Stroke::strokeVerticeAt(i) that returns the i-th StrokeVertex of the Stroke.
