matplotlib Code

Fix clip path in polar plot legend.

Lots of minor bug fixes.

Removed unused imports.

Increased coverage of backend_driver.py to include almost everything
in axes.py. Lots of little bug fixes.

Simplified sharing axes again.
Plowing through -- making more examples work.
First pass at updating collections (LineCollection mostly works)

Progress on agg_buffer_to_array example.

Lots of progress on Polar transform refactoring. Added point_in_path algorithm.

Removed transforms on the C++ side -- removed many methods that depend
on it in backend_agg in preparation for path generalization.
Lots of general renaming...

New milestone -- resizing figure window works. shared_axis_demo.py
works. (Uses callbacks to track changes between axes's).

More work on dviread and usetex in pdf. It is more usable now,
so I am renaming the method from _draw_tex to draw_tex.
