Hi Lydia,
We should probably adopt a convention. I used the positive-inside
convention only because that is what folks around me are using. But now
I'm discovering the positive-outside convention is probably more what
others are accustomed to. I wouldn't be able to do it any time soon, but
I can change my code to produce positive-outside. I don't have a strong
preference either way.
Josh.
