    Default Pcbnew zoom values.
    Limited to 19 values to keep a decent size to menus.
    Roughly a 1.5 progression.
    The last 2 values are handy when somebody uses a library import of a module
    (or foreign data) which has a bad coordinate.
    Also useful in GerbView for this reason.
    Zoom 5 and 10 can create artefacts when drawing (integer overflow in low level graphic
