matplotlib Code

Avoid use of "not found everywhere" uint8_t with npy_uint8, since we do include and rely on Numpy.

Remove extraneous "public:"

Speed up nan-handling on curves. Add test case for this.

Fix shortening end of path bug in simplifier. Speed up clipper by not using a queue.

Remove test code.

Create path_cleanup code for use by the Mac OS-X backend. Refactor C++ code to follow Numpy's guidelines for linking multiple C files into a single extension. Remove dependency of Agg backend on _image.cpp and _ft2font.cpp (simplifies linking problems and reduces generated code size).

Rework the nan-handling/clipping/quantizing/simplification
framework so each is an independent part of a pipeline.
Expose the C++-implementation of all of this so it can be
used from all Python backends. Add rcParam
"path.simplify_threshold" to control the threshold of
similarity below which vertices will be removed.

Make curves and NaNs play nice together
........

Change simplification algorithm so it always returns points from the original data, rather than extrapolated ones. This is somewhat experimental.

Remove need for m_done flag in simlifier -- we can just put a path_stop onto the queue instead. Saves one boolean test on every iteration.
