If I remember correctly Windows does something wierd here.  If you set
your machine to "small fonts" then it assumes one value for
pixels-per-inch.  If you set it to "large fonts" then it assumes another
value.  Neither of them may be the actually PPI of your screen.  I think
it has to be done this way for back compatibility.
