------- Additional Comments from Adam Barth <abarth at webkit.org>
I put on my Java thinking cap and figure out what this actually does.  It lets
the UI keep track of how much page scaling is possible so that it can properly
react to various pinch-like gestures.  It's also used by the browser UI to
adjust the size of various overly elements to scale them commensurate with the
page.
