usetex font problem

Oops, I also added the font.family to the Agg key

Checking in lib/matplotlib/backends/backend_agg.py;
/cvsroot/matplotlib/matplotlib/lib/matplotlib/backends/backend_agg.py,v
<-- backend_agg.py
new revision: 1.42; previous revision: 1.41

It would be useful to centralize the cache key generation, since it is
fragile to have texmanager and backend_agg doing this
independently....
