matplotlib Code

Continued progress getting more examples to work. Working examples
(with TkAgg backend only) are marked in PASSED_DEMOS for the curious.

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

Lots of new docstrings. Reasonably good state for polar plots.
r-axis labels can be dragged on polar plots. r-scale can be zoomed on
polar plot. Lots of other minor changes too numerous to mention.

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

Lots of minor fixes

Got legend working with new transforms

Transferring work-in-progress

Sends paths to backend only once, and after that uses the "native" path by
reference with a changing transform. Started recongfiguring
patches.py to use only Paths under the hood (to take advantage of this
caching). Removed many methods from backend_agg that should
eventually be replaced by draw_path, at least in theory.

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.
