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.
