Summary Hierarchy of renderers for elements with a document needs to be unified

Today, we have 3 elements which can contain an HTML document: HTMLIFrameElement, HTMLFrameElement and HTMLObjectElement. Their renderers are: RenderIFrame, RenderFrame and RenderEmbeddedObject, respectively. Their hierarchy is: ... RenderPart RenderEmbeddedObject RenderFrameBase RenderIFrame RenderFrame So common functionality has to go into RenderPart, which is really too broad. It would be better with an added class: ... RenderPart RenderFrameOwner RenderEmbeddedObject RenderFrameBase RenderIFrame RenderFrame This more closely mimics the corresponding Element hierarchy and RenderFrameOwner would give us a place to put the common code.
