matplotlib Code

added ploticos.py example for plotting triangular grids.

don't force adjustable='box' for AxesGrid compatability. Added example that uses AxesGrid.

[2908399] Support clip paths in QuadMesh with gouraud shading

[3010563] misaligned title text when using GTK backend

[3011582] stix_fonts_demo.py assert error

When matplotlib is compiled without -DNDEBUG, we get this error on one of the example:

$ python stix_fonts_demo.py
python2.6: CXX/cxx_extensions.cxx:1320: virtual Py::PythonExtensionBase::~PythonExtensionBase(): Assertion `ob_refcnt == 0' failed.
Aborted

added bbox_inches and pad_inches to savefig signature

fix legend doc typos

Axes.grid controls minor and/or major lines; axis.grid allows 'both'

put 3 more pytz zoneinfo files under svn control; they were missed by accident when I updated pytz
