Thank you for these suggestions. I've been doing some digging into 
gState and can't quite figure out what purpose it serves.  I don't think 
there's an equivalent CoreGrpahics call that we can substitute in for it 
(I've been looking at it from that angle). I'll give this approach a try 
and see if I can make any progress. More in a few days, hopefully.

What a headache! Some might call the Win32 and Xlib API's may be 
moribund, but I prefer Debian-speak here: "stable." Grumble, grumble, 
grumble...
