How did you come to the decision to change from Ref to RefPtr?

Is this WTF::move() necessary?

> +    return WTF::move(result);

Ditto.

> Source/WebCore/css/RGBColor.cpp:59
> +    return WTF::move(result);

Ditto.

> Source/WebCore/css/RGBColor.cpp:67
> +    return WTF::move(result);

Ditto.

Oops, I confused this change with other cloneForCSSOM(). Fixed.

I'm assuming you plan to remove the use of PassRefPtr in the arguments in a separate bug/patch.

Ditto.

This is OK as-is. The methods of this class, including this method, assume that argument tokens is a non-null pointer. So, we should change the data type of the argument tokens from CSSParserValueList* to CSSParserValueList& in all applicable methods of this class. This can be done in a separate bug.

I'm assuming you plan to remove the use of PassRefPtr in the first argument in a separate bug/patch.

> Source/WebCore/css/CSSParser.h:357
> +    RefPtr<StyleRuleBase> createMediaRule(PassRefPtr<MediaQuerySet>, RuleList*);

I'm assuming you plan to remove the use of PassRefPtr in the first argument in a separate bug/patch.

> +    RefPtr<CSSBasicShape> parseInsetRoundedCorners(PassRefPtr<CSSBasicShapeInset>, CSSParserValueList&);

Ditto.

Yes, right. Now I focus on removing PassRefPtr in return type first. Then I will plan to reduce use of PassRefPtr in the arguments too.

Ok, let me file a new bug for it.
