Spheres often don't look smooth enough. Apparently the
algorithm that decides how many polygons to use is a
bit more conservative than it should be.

    Seriously, there is in fact a problem with this heuristic
    (heuristics always have problems - if they didn't they
    would be algorithms). The calculation takes place
    in 'normalized device coordinates' which do not take into
    account the size of the window on the screen. The
    calculations are reasonable for a small window, but not
    reasonable for a large one.

    this is a feature, not a bug.
