matplotlib Code

Update to version 1.7.2 of pyproj

Revampled polar plot example.

mask new TextWithDash, bugs found

draw_lines requires the transform when called, forcing use of new API

TextWithDash extends superclass draw and get_window_extent
methods, instead of replacing them

convert some tabs to spaces

refactored TextWithDash, derive from Text rather than delegate

Specifying an aspect ratio now works with zoom and pan on ganged plots,
with no special code in backend_bases.py

newstyle collections fix

patched backend bases line collection to work with newstyle API
