Call GetGrayRgn() to get the region defining the desktop area (union
of screen areas - menu bar), and use the bounding box of the region.

This is somewhere in Inside Macintosh V (Graphics Device chapter, I believe).
Possibly you need to check whether the trap exists and use the low memory
global GrayRgn instead if it doesn't.  Of course, depending on how
GetGrayRgn() is implemented, it might simply return the value of GrayRgn
itself!  Anyone know?
