    The line felt too thin.
    
    Note: I am still sceptical with the principle of an increase at the rate of
    1/200% instead of 1/100%.
    
    Also, I am sceptical with changing painting dimensions to int when Qt 
supports
    doubles for everything (see e.g. 463bd17d). If the goal is to force
    integer-width solid lines then one could try to disable antialiasing on Qt's
    side.
    
    I think the painter should move in the other direction, towards more 
doubles and
    fewer ints. For instance, for Hi-DPI, Qt could probably take advantage of 
the
    increased precision even without AA. (Then one would have to fix the problem
    regarding uneven lines, mentioned in the above commit, in another fashion.)
