        [GTK] Toggle buttons visually broken with GTK+ 3.13.7
        https://bugs.webkit.org/show_bug.cgi?id=136130

        Reviewed by NOBODY (OOPS!).

        No new tests. Hopefully covered by existing tests, and our tests only
        run with GTK+ 3.6 anyway.

        * platform/gtk/RenderThemeGtk3.cpp:
        (WebCore::paintToggle): use GTK_STATE_FLAG_CHECKED when compiling for
        GTK+ 3.13.7 and above to ensure toggle buttons display as toggled.
