A more careful reading of the pdf spec reveals that Type 1 fonts
embedded in pdf files are not actually supposed to be in pfa format,
but a similar format where the encrypted part is not encoded in
hexadecimal, and where the "fixed-content" part at the end may be
omitted. This fixes the problems with Preview.app.

Revision: 3798
http://matplotlib.svn.sourceforge.net/matplotlib/?rev=3798&view=rev
Author: mdboom
Date: 2007-09-06 11:50:08 -0700 (Thu, 06 Sep 2007)
Log Message:
-----------
Refactoring of FigureCanvas*.print_figure so that each backend does
not have to track all other possible filetypes. This should make it
easier to add new filetype backends without updating lots of places.
All GUI backends have the same base set of filetypes they support,
defined in FigureCanvasBase. Non-GUI backends, for the most part will
still only write to their own file format (and not do any
switch_backend magic.) All GUI backends (where possible) now generate
a list of file patterns for their file chooser dialogs, rather than
having hard-coded lists.
See FILETYPES for matrix of filetypes supported by each backend.
