mpl doesn't explicitly do anything with nan .  I think what you are
observing has something to do with how agg is handling these values,
because they are passed straight through to the backend.

So, for now, there is no place in the mpl code to go, though I would
like to add some support for nan, or masked arrays, or masks, in the
future.
