Looks great.

Kinda a mouth-full, but I don't have better.

> Source/WebCore/platform/graphics/GraphicsContext.h:560
> +        : m_context(context)
> +        , m_saveAndRestore(saveAndRestore)

I think we technically indent these on level (differnet from how xcode does things).

> Source/WebCore/platform/graphics/GraphicsContext.h:576

> +            m_context.save();

We could make this a counter instead.  Not sure how useful that would be.

Oh, that's so sexy.

Bleh.  (For another patch. :)

You call it "stateSaver" other places.

LGTM.

> +    GraphicsContextStateSaver stateSaver(*paintInfo.context, false);

I think we should turn this bool into an Enum at some point.
