Sweet patch, just some stylistic comments.

Since we're sure that m_image can't be null, I'd write this like so:
return toStyleCachedImage(*m_image).cachedImage()->url();

> Source/WebCore/css/CSSImageSetValue.cpp:64
> +        toStyleCachedImageSet(m_imageSet.get())->clearImageSetValue();

Same here.

> Source/WebCore/css/CSSImageSetValue.cpp:194
> +    CachedResource* cachedResource = toStyleCachedImageSet(m_imageSet.get())->cachedImage();

And here.

> Source/WebCore/css/CSSImageValue.cpp:108
> +    CachedResource* cachedResource = toStyleCachedImage(m_image.get())->cachedImage();

And here.

> Source/WebCore/rendering/style/StyleImage.h:97

Not that it matters much, but "resource" seems like a strange name for what's being passed around here.
