As Tom Dowdy of Apple (dowdy@apple.COM) has pointed out to me, there's a 
perfectly good ROM call, GetWMgrPort(), which will return a pointer to the 
Window Manager's GrafPort.  As Tom says, "Using low memory when there is a 
ROM call available is a really bad idea."

I agree.

Mea culpa, mea maxima culpa...
