matplotlib Code

Change mathtext.* rcParams so they accept a string which is a set of
arguments to the FontProperties constructor. This has been added to
both the classic and traits based configuration frameworks.

Improve font manager so default font names like "serif", "sans-serif"
etc. are looked for across all fonts in that mapping, not just a
single hard-coded one.
Add DejaVu fonts as an alternative to Vera fonts if present.
Fix how mathtext non-Computer Modern fonts are specified.

Expose Unicode font functionality for mathtext through rcParams

Removed mathtext2. Fix horizontal centering in mathtext. Put all
mathtext_examples on one plot.

Add kwarg 'markup' for all text that allows the user to choose either
'plain' or 'tex' markup. A default may also be provided in the
rcParam 'text.markup'.

First commit of code to embed fonts as paths in SVG files.
