   /* An alpha mask to be applied to all icons on the navigation bar (header menu).
    * Icons are have a size of 20px but usually we use MDI which have a content of 16px so 2px padding top bottom,
    * for better gradient we must at first begin at those 2px (10% of height) as start and stop positions.
