matplotlib Code

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.

Minor changes -- committing so I can merge again.

Just marking a milestone -- about to totally rip things up again.

Running mathtext_demo.py without transforms.py/cpp. Totally broken,
though. Not surprising... ;)

Creating branch to work on transforms/projections refactoring.
