matplotlib Code

Add unit test to ensure that rendering complexity exceeded exception is properly propagated to Python.

Uses doubles for rectangle clipping everywhere in the Agg backend.

Do image clipping of images in doubles rather than ints -- prevents the "disappearing image when zooming in too far" problem.

Fix severe slowness with very high image magnification.

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)
