It would be better if both behave in the same way, for consistency, don't 
you think so ? I mean, that's a bit painful now.

Furthermore, display coordinates are, *to my opinion*, more useful. In many 
cases I've seen, you want for example your text to be 5 or 10 pixels below 
the top of the window, no matter the size of that window (say, for example, 
to display patients info). If you use normalized coords and resize the 
window, your text will move...

What do you think ?
