matplotlib Code

Fix bug in mathtext related to \dots and \ldots (Thanks, Fernando Perez)

Fixed a bug in RRuleLocator that generated invalid datetimes when padding the axes bounds for large ranges of times or with times that are close to the boundaries of valid datetimes.

Change default joinstyle to round

User specified tickers and labels for any given axis will now take precedence over "default" values.

Fix TkAgg backend.

Reduce number of marker objects in pdf output

Make resolution of 1 be the default on a polar plot.

Fix markevery -- the tuple form was not working (if it ever was).

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).

Fix bug in markevery where markers were being recursively removed.
