Use GetPortLoc and SetPortLoc to retrieve and set the LocInfo record in the
GrafPort. LocInfo records are described on page 16-13 of toolbox ref 2.

Good luck, and let us know if you discover anything -- enhancing quickdraw
for larger screens has a lot to do with the LocInfo records and how quickdraw
handles them.
