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.
