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?

[pix is exactly the same size and depth as the win]

example:

         ...
         ...

        XSetWindowBackgroundPixmap(dpy, win, pix);
        XDrawLine(dpy, pix, gc, x0, y0, x1, y1);
        XClearWindow(dpy, win);
        XFlush(dpy);

does the line appear in win?

I have tried this on several X11R3 and R4 servers, and on all but one
update the window from the pixmap after the XClearWindow.

Thanx for the help,
arman.
