    app: better defaults for image dimension.
    
    Current defaults are from another time. Acceptable defaults could be
    common screen resolutions. 1366x768 is apparently the most common
    (according to various stats on the web), but since we target advanced
    graphics artists, let's go for 1920x1080, which is the second most
    common resolution, also known as Full HD.
    For unstable builds, let's have at least one odd number, uncommon ratio
    and higher values, encouraging tests with less common numbers and bigger
    images. I chose 2001x1984. Feel free to update to any other funky values
    following these "unstable" rules.
