NetBSD on amd64. Xorg 1.9.2.

Oh, I can get things to show up on screen. What I'm working with is the
graphicsmagick lib, as a shared object, being loaded into my app. So, I
can: "magick::image myimg; myimg read -file test.jpg; myimg display", and
get a picture on the screen. And I can set the quality, and have it behave
like I'd (sort of) expect: "myimg infoset -quality 2; myimg write -file
test2.jpg", then view that file, and it's low-quality. What I can't do is
"myimg setinfo -display fu:0.0", and seem to have that take effect. A
subsequent "myimg display" happily just displays it on my local display.

X11 is not fully broken, but setting options is failing somewhere. Again,
wouldn't be suprised if PEBKAC, but setting the ImageInfo->server_name
is not working like I'd expect.
