    effectiveSizeHint has a quirky behavior, one of the quirkinesses is when the hfw function is
    combined with user-specified min/max sizes. The input to hfw function (e.g width) must be within
    the min/max width constraint, and the output must be within the min/max height. This sets up a
    loose dependency between minimum width and maximum height (or minimum height, depending on the
    type of hfw function). Note that its only the concrete subclass that implements that hfw
    function that knows if this dependency means that the height will increase or decrease when the
    width is increased.

    The application should try to ensure that the user-defined sizes are within the range so that
    they don't conflict with the hfw function.

    Suppose, for instance that the hfw function is:

        height = 2000/width

    and the item has these user-defined sizes:

        min  ( 5,  5)
        pref(100, 10)
        max (500,100)

    what is the return value if one calls item->effectiveSizeHint(Qt::MinimumSize, QSizeF(10, -1)); ?
    The sizeHint() function would return QSizeF(10, 200), but it would be bounded down to 100 due
    to the max value, so it would return (10, 100). This is not what the item expects, since it
    really wants that its hfw is respected. If this is a label with wrapped text, this would most
    likely lead to that some text is clipped. This is certainly not what the app developer wants.
    Now, it would be better if the user changed those constraints to match the hfw function:

        min ( 20,  5)
        pref(100, 10)
        max (500,100)

    here, it says that the width cannot be smaller than 20. This is because if it becomes smaller
    than 20 the result of the hfw function would violate the max height (100).

    However, there is a similar problem if the width passed to the hfw function reaches *max* width:

    the sizeHint() function would now return QSizeF(500, 4), but 4 is smaller than the minimum
    height (5), so effectiveSizeHint() would return (500, 5), which would leave too much space.
    In this case, setting the max width to 400 fixes the problem:

        min ( 20,  5)
        pref(100, 10)
        max (400,100)


    The implementor of a hfw widget must be aware of this when sizeHint() is reimplemented, so that
    the default min and max sizes works sensible. (unfortunately the implementor does not have the
    control over user-set values).
