It looks like this can just be rebaselined.

Nit - could consider using contract instead.

Nit - addEventListener(‘load’, runTest);?

Ditto.

Do these really need to be iOS specific? They seem pretty general. We really should be aiming to have less platform specific code like this.

Agreed. I started to clean things up and it got messy; it's unclear if all the callers want to include borders or not, and which want the interaction rect vs. the content box rect.

Will you finish :) ? Since these are static, and don't rely on the Page at all, it might also be better to move them to their own ElementGeometry.h/cpp (or whatever) file. And/Or move them to WebCore.

Not right now.

Bummer.
