Is this testable?

> Source/WebCore/platform/ScrollView.h:485
>      IntRect platformVisibleContentRect(bool includeScrollbars) const;
>      IntSize platformVisibleContentSize(bool includeScrollbars) const;
> +    IntRect platformVisibleContentRectIncludingObscuredArea(bool includeScrollbars) const;
> +    IntSize platformVisibleContentSizeIncludingObscuredArea(bool includeScrollbars) const;

It almost feels like the "including obscured area" could be an enum param to platformVisibleContentRect/Size.

Thanks Simon! Joe and I are still thinking about a test case…we haven't come up with one yet, but it would be very valuable. In terms of the enum parameter, I do think that is a really good idea, and I think we should consider it when we clean up these functions, which I really really want to do.

Oops, http://trac.webkit.org/changeset/171952 is needed too! It's critical, in fact! I accidentally had that part of the change reverted from when I was trying to see if the layout tests I was trying to make actually triggered a difference from this change.
