        Bug 26156: In view-source mode, always render the contents using HTMLViewSourceDocument
        https://bugs.webkit.org/show_bug.cgi?id=26156

        When in view-source mode, render the contents using HTMLViewSourceDocument
        regardless it's applicable for any plugin or not.

        Chromium tells WebCore to render the contents of specified URL when
        view-source: prefix is added to the URL. But currently, DOMImplementation
        ignores inViewSourceMode() when the MIME type is indicating that the contents
        are neither texts nor HTML family documents.

        For example, we can check the contents of asf file without launching media
        player. Rendering contents for view-source:-specified input is not what user
        expects.

        http://code.google.com/p/chromium/issues/detail?id=10545

        I want to fix this issue by this patch. IMHO, regardless of this Chromium
        specific issue, I think we should force use of HTMLViewSourceDocument when
        inViewSourceMode() is specified.
