    mutter: don't show the resize popup for 2 x 2 size increments
    
    In a HiDPI environment, all gtk+ apps will report a 2 x 2 size
    increment to avoid odd size. But that does not mean they are
    resizing in cells like terminals, so they resize popup should
    not be shown.
    
    Ideally, we should ignore <= scale x scale increments, but in
    practice scale is 1 or 2, and even in a lo-dpi setting a 2 x 2
    increment makes little sense so let's keep the patch simple.
