matplotlib Code

mathtext.* font rcParams now use fontconfig patterns to specify fonts.
Support converting FontProperties objects to/from fontconfig patterns.

Added step plot based on patch by Manuel Metz

Support get_image_magnification in pdf backend

There's no need to link ttconv with CXX (it hasn't used it for
sometime, but I forgot to remove it from the build.)

Update PyCXX to latest upstream stable version (5.4.0)

Extremely minor bugfix that prevents the cycle finder from printing
out dictionaries.

Fix \sqrt (broken when I made the parser more strict).

Fix a buglet affecting getp: if a numpy object has shape==(),
you cannot take its length.

rcdefaults working with mplconfig

Make rcParams.update(rcParamsDefault) when new traited config is
switched on.
