Right again Jason. I was basing my layout off of the iPhone slider because that is what we use in the Settings section of the application for this feature. Poor oversight on my part when I was working on this revision earlier today to not adjust for the lack of the slider button.
Since pinch to scale is somewhat hidden, this is actually a secondary approach to font adjustment in the USA TODAY update. The more straight forward approach for scaling that is being added to the application is through Settings. Couch posted a screen of that for context.
This new screen I'm uploading shows the five equal areas. I think that helps a lot as well.
