I'll rescind this last statement. I can see use for it in a print  
only style sheet, in limited circumstances where I know what the dpi  
of the device is. But I'd be happier if I could just specify a 1/4  
pixel line for a printer and have it rounded to 19 pixels on a 9600  
dpi printer. I'm not sure if this actually happens in all browsers or  
not.
