Perhaps not really a bug, but now a limitation.  Definitely file an 
enhancement request.  As John pointing out, the control could have 
been already modified to support Hi-DPI (aka resolution 
independence).  My guess is that Apple is using bitmapped images and 
are just providing multi-res flavors (72 dpi and 288 dpi).

But, IMO, that's bad!  If I were implementing the control, I would 
allow any size and would either vector-based images (e.g. PDF) or 
drawing primitives for the content.

Note that you'll see the same issues for most other controls as well. 
While they do support res-ind, their sizes are pretty much fixed point-
wise.
