soc-2008-mxcurioni: Tested SWIG-less environment more and understood why the 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)
