(http://freestyle.sourceforge.net/doc/html/index.html) has been
incorporated into the Blender/Freestyle Python API implementation
in the form of Sphinx-based embedded docstrings. Some C++-specific
descriptions of classes and functions were revised so that they are
suitable for Python programmers. Missing docstrings were filled,
and sparse descriptions were extended. By means of the new
documentation system for Blender, an up-to-date Freestyle Python
API reference will be part of the Blender 2.5 documentation.

Also exported the Operators.chain() function.

of the original styles are supported: stroke attributes are correctly taken into account, Python shaders are supported. Added SamplingShader.

polymorphism for the following classes: BinaryPredicate0D (__call__), BinaryPredicate1D (__call__), UnaryPredicate0D (__call__), UnaryPredicate1D (__call__), StrokeShader (shade), ChainingIterator (init, traverse).
Other methods could easily be supported in the future. The method now works as planned for the contour style. For style modules with Python shaders, there still is a problem that I will fix right away.

former predicate methods were not working. As Stéphane had mentioned a few months ago, Freestyle uses SWIG directors to provide cross-language polymorphism. The API and the system I had provided did not support that feature and only implementations in C++ were supported. To correct the problem, after researching how directors are implemented in SWIG, I provided the same functionality. So far, I only provided the code for the UnaryPredicate1D class and it works. The implementation is in intern/python/Director.cpp and Operators.cpp. I will port the remaining directors tonight and continue to test it.
To prevent strokes from piling up after each render, I clear the canvas at each render now (as it should have been all along)

API renders a correct result for the test style module 'contour.py'. More testing needs to be done to make sure my work was correct.
To make it work, I had to:
- update Operators to include all of its methods in the Python API
- redefine the Freestyle modules as local classes, allowing predicates to support the __call__ method (I found out that Python does not allow modules to be callable). The API is defined in the new freestyle_init.py file.
- remove all references to former Python Freestyle API (located in source/blender/freestyle/python/, under the Freestyle.py file) and replace it with the new API file.
- normalize all constants related to the Nature class
- redefine the logical_operators.py file so that AndUP1D, OrUP1D and NotUP1D would be subclasses of a UnaryPredicate1D subclass having a operator() implementation. Using UnaryPredicate1D as a superclass would somehow prevent calls to the operator(). For the time being, I chose ContourUP1D (even though it does not really matter which subclass it is, since the __call__ method is redefined in all of these classes). I will implement this classes in C++ to get rid of the problem altogether.
- turn off a few classes that somehow are not well recognized (Noise, Curve...). I will reenable them later once I understand what's going on.

classes, except EdgeModifier and TimestampModifier (which aren't even ported via SWIG), are available under the Blender.Freestyle module. Testing of the porting will now begin to make sure the SWIG-less system works as the original.
Quite a few modifications were made to finish the API:
- Freestyle's SConscript was modified to catch all files within the intern/python directory, allowing integration of future shaders implemented in C++.
- the Operators class was ported, with a special care of making its methods static (using the METH_STATIC flag in the tp_methods method definitions)
- all of the type-checking functions [ BPy_[class name]_Check(obj) ] were changed to allow subclasses to be seen as that type too: instead on looking at the ob_type value, the PyObject_IsInstance function is used.
- all of the iterators can now retrieve the object pointed to by the operator, using the getObject() method. A directedViewEdge pair is returned as a list of the two elements in the pair.
- all of the style modules were copied to a style_modules_blender/ folder and were modified to use Freestyle as a Blender's submodule. IntegrationType and MediumType was also integrated (for example, changing MEAN to IntegrationType.MEAN).
Testing now begins. If everything works correctly, I'll move on to lib3ds removal right away.

prefix to avoid library name collision.
Included MediumType's initialization at proper time to avoid Blender's crash.
