    albumartcache: Also consider height when scaling covers
    
    When scaling down the cover artwork, the current code only understands
    the case where the width of the cover is the big axis. The problem with
    that is that it ends up overgrowing covers which the height is the big
    axis, and breaking the layout of the Albums view.
    
    Fix that by checking which is the biggest axis and always scaling down
    the cover to fit it.
