    a client cannot find out about a root window's border/background
    (i.e.  the one at the top of the chain of CopyFromParent defaults).  Pray, why
   is this?

The background/border pixmaps may be freed immediately after creating
the window or changing the window attributes, thus there may be no valid
pixmap id to return to the client.  Background/border pixels are turned
into "pixmaps of undefined size" (see XSetWindowBackground) by the server.
