    34 Page scale is used to implement zooming gestures.  This is typically done in conjunction with using a porthole/virtual viewport model where the viewport that the user sees is a subset of the viewport as exposed to the web page.  Page scale effects the virtual viewport, not the CSS viewport, so layout is generally speaking not impacted by a changing page scale.  Fixed position elements are an exception to this - they are often rooted to the virtual viewport and not the CSS viewport.  This behavior is not well defined and there are many behavior differences between different ports.
