Never mind, I think I got it. I saw the special meaning of a leading 
slash in an include/exclude pattern in the man page. So:

rsync -aznvvv --exclude '/pix/trinity/' /pix ${DEST}::root
...
[sender] hiding directory pix/trinity because of pattern /pix/trinity/
...
[sender] make_file(pix/0/trinity,*,2)
[sender] make_file(pix/0/pix/trinity,*,2)
[sender] make_file(pix/0/pix/trinity/foo,*,2)
[sender] make_file(pix/0/trinity/trinity,*,2)

So it excluded /pix/trinity/ as desired, yet included other paths that 
had "/pix/trinity/" in them such as /pix/0/pix/trinity/foo"

I only need the single pattern at the moment so --exclude is simpler 
than a filter file, but just for the record I verified a filter file 
like this worked the same too:
- /pix/trinity/

Also please disregard the "+ *" in my previous examples. I know they are 
superfluous. They were in there only because I was starting with a copy 
of a different script that originally had "- *" at the bottom to include 
some patterns and exclude everything else. At the moment I need the 
opposite of that so when I reversed all the + & -, I ended up with a "+ 
*" at the bottom.
