Well I don't know why I specially would like to do that, but it gives us 
flexibility without making the API more difficult to use (the ratio mode 
can be optional). Some people might want to have more control... This 
was just a good compromise between Philip's original idea, and the GNOME 
version. I don't have some real usecase behind that :-)
