In stead of using a "magic number" of 150, it would be better to query
the underlying OS directly. Obviously this is not portable, but we
have done this under Windows. Querying the width or height of the
taskbar, and subtract that from the screens size.

But then you can have a multi-monitor system too, so now Screen size
and Desktop size differs too... ;-)

And don't for get the Golden Ratio for window sizes:  1.618
