orientedViewEdgeIterator. * Simplified Python-related error handling in C++ class definitions. The definitions of the following C++ methods were simplified and most code segments using the C/Python API were moved to Director.cpp. ChainingIterator::init() ChainingIterator::traverse() UnaryPredicate0D::operator()() UnaryPredicate1D::operator()() BinaryPredicate0D::operator()() BinaryPredicate1D::operator()() UnaryFunction0D::operator()() UnaryFunction1D::operator()() StrokeShader.shade() * Moved part of the introspection-based automatic type conversion code from BPy_Interface0DIterator.cpp and Director.cpp to BPy_Convert.cpp for the sake of better code organization. * Fixed an uninitialized member in StrokeVertexIterator___init__().
