Add an offscreen area scoring to improve choosing offscreen areas to kick

    out when allocation can't find a free area of the requested size. When
    offscreen pixmaps get used, the offscreen area's score is increased by
    a constant value. Every certain number of increases, all offscreen area
    scores get decreased by a fraction. When choosing a set of areas to
    remove for a new allocation, the set of areas with the smallest total
    score is chosen for removal. While this is not the smartest system, it
    prevents things like always removing the first offscreen area in memory
    (likely the most recent) to be kicked out when doing replacing.
