In _Ewk_View_Private_Data struct, viewport_arguments variable is defined. However, the viewport_arguments values are set to 0 because this structure is created by calloc(). So, if application invokes ewk_view_viewport_attributes_get() first without viewport meta tag, the ewk_view_viewport_attributes_get() returns wrong viewport values because viewport attributes values are set 0 instead of -1(ValueAuto).
