    If I'm using XSetWindowBackgroundPixmap(dpy, win, pix), is it
    guaranteed that subsequent changes to the pixmap will appear in win,
    whenever XClearWindow(win) is called?

You will find explicit words about this in both the Xlib and Protocol
manuals.  In Xlib, in Section 3.2.1 (p. 34 in the Digital Press book).
In the Protocol, under CreateWindow (p. 365 in the Digital Press book).
(I'm afraid I couldn't find explicit words in the O'Reilly manuals.)
