No EWS because the patch doesn’t apply.

I suggest putting in a patch that only adds the new typedef and is entirely mechanical, and leaving the part that introduces new functions as a separate far smaller patch.

> Source/WebCore/platform/graphics/IntRect.cpp:142
> +IntRect enclosingIntRect(const IntRect& rect)
> +{
> +    return IntRect(rect);
> +}

This must be inlined in the header. We do not want to pay a function call to convert an IntRect to an IntRect.

> Source/WebCore/rendering/LayoutTypes.h:89
> +inline bool layoutUnitEquals(LayoutUnit a, LayoutUnit b)

If the idea here is to use a definition that involves epsilon, then I think you need a different name. After all, == does not use epsilon, so the name "equal" is already taken.

LGTM.  You may want to let Darin take another look too.

Thanks Eric,

I'll hold of landing this for another day or so to give Darin a chance to look at it.
