[Isaac] Matplotlib font encoding problem

I'm not sure what is going on here, but I can tell you that

FYI, I get the same problem on Windows XP with simple_plot.ps.

It's a simple win32 gotcha: you have to open binary files on win32 as
'rb'. linux doesn't make a distinction but windows does.

win32 ps users, you need to edit
site-packages/matplotlib/backends/backend_ps.py line 356 and use

    font = file(fontfile, 'rb')

The corrupted binary data hint triggered the idea - thanks Paul for
the hint and Alan for the bug report!
