*blink* Well, that makes things simpler. I latched onto the
gfx_pixmap_t blocks because they were treated as XImages. I didn't see
anything about the visual planes in the actual xlib driver. But I'm
digging around more now.
So I take it that the Window and the Pixmap visual[] array are the four
planes I need to munge... Okay. That will be simple enough. :)

I added a shmid to the pixmap_t type, but I will probably do away
with all of that.
