Debian Bug#585442: python-matplotlib: crashes when calling axis() after imshow()
This allows the C++ exception raised when Agg rendering complexity is exceeded to percolate up correctly to a Python exception, rather than crashing the interpreter.
Fixes problem in last commit.

tick_params: fixed errors in handling top, bottom, etc. kwargs.

Let pcolor antialiasing default be controlled by patch.antialiasing.
See ticket 3017725. In most cases antialiasing is better than, or
nearly as good as, non-antialiasing. A note about artifacts is now
in the docstring.

add antialiased=True to pcolor call (SF bugs item #3019150)

[3018374] Link to examples is hardcoded

[3015217] Don't add piwik code to html docs by default
This prevents the web browser from making remote http requests when browsing the docs locally.

Add Axes.tick_params and pyplot.tick_params to control tick and tick label appearance.
This allows interactive modification of tick and tick label color, size, etc.

revert r8445,8446 and fix plot_directive.py to support sphinx 1.0

remove align_ylabels.py entry from howto_faq.rst to test doc-build
