Note that documentRect() does apply a transform. I don't know if you really wanted 

unscaledDocumentRect()

here or not. I'm not sure.

Should probably have absolute in the name.

> +LayoutRect Element::eventBoundsOfElementAndDescendants(bool& includesFixedPositionElements)

Should probably have absolute in the name.

This broke Windows build:

I don't see anything wrong with the code, will try a clean build.
