Fixing windows build failure

Changing ExclusionShapeValue to not conditionally compile, as RenderStyle::shapeInside/Outside must return a value regardless of whether CSS Exclusions are enabled.

I think OutsideExclusionShapeValue does not make any sense. It is adding a new class without any sense IMO.

Well, it is <shape> (a Basic Shape), 'outside-shape' and 'auto'. It should be more clear here.

> Source/WebCore/css/CSSValueKeywords.in:917
>  // -webkit-wrap-shape

this is not called wrap-shape anymore, is it? Can you update this comment please?

There should be an FIXME here, with a link to a bug report.

You may want to blend with outside shape in the future. Please add an FIXME here.

Can you rename it to oldExclusionShape?

indentation looks wrong here.

I don't think that you need to create this class at this point. It doesn't have any information. Just use ExclusionShapeValue for everything and remove OutsideExclusionShapeValue and ShapeExclusionShapeValue for now. Then we don't have unnecessary vtables and inheritance.
