[Xr] about Xr design

Newbie question:

I just started to play with Xr and I note that the library works with pixel 
metrics (with the possibility to scale with XrScale).

My question is: why not device independent metrics, as in PostScript?. The 
README file asserts that the API is based on the PostScript operators, so why 
not include also the device independent metrics?

Of course I know its possible to work with device independent metrics if I 
know the resolution at which I will display and some work with XrScale. The 
question is simply about a matter of design of Xr.
