matplotlib Code

added width, height to Basemap.__init__

added the ability to specify the map projection region using width and height keywords
(instead of lat/lon or lower and upper right corners).

added get_clim to scalar mappable

mathtext2 - added support for complex sub/superscripts (i.e.fractions etc.)

font_manager.py: added /usr/local/share/fonts to list of X11 font directories

Initial support for complex fractions. Also, rendering is now completely separated from parsing. The sub/superscripts now work better.

moved qApp creation from show() to FigureCanvasQt.__init__()

For qt backends, dont create a QApplication when the backend is
imported. Do it in show().

fixed copyright information

mathtext fonts are now searched in the OS font dir, and in mpl-data dir. env is now not a dict, but a separate class instance.
