rename Python module from 'raytracer' to 'pyrit'
improve Python binding:
- new objects: Container, Octree, KdTree, Shape,
Pixmap, Sampler, DefaultSampler
- all shapes are now subclasses of Shape
- clean, remove redundant Getattr's
- Raytracer render method now just wraps C++ method
without doing any additional work
adjust all demos for changes in Python binding, remove PIL dependency
add demo_PIL.py as a example of pyrit + PIL usage
render_nff.py now either loads file given as a argument
or reads input from stdin otherwise
fix bug in pixmap float to char conversion
#!/usr/bin/python
# this demo needs dragon model from
# http://graphics.stanford.edu/data/3Dscanrep/
