Thanks Tor for the helpful response. This seems a lot more sane to me. More
comments follow:

Just to clarify, "root" is root X window? So I could theoretically have one GC
that
I use between windows of the same application? "Depth" must mean "Color Depth"
and
not window recurrsion depth. Guess my brain is wired weird, because that's
what I
thought the first time I read it.

*blush*. Sorry, missed that. Should teach me to read all the documentation,
including the param comments and not just the main description.

I guess the way I'm currently doing my GCs is fine too since this is what
probably
happens on Win32. I'll still move over to one global GC just because it's
cleaner.
Thanks!
