     Given a 1-bit pixmap, I need to create an 8-bit server image.  I did:

	Server_image	result;
	Pixmap		temp;
	XGCValues	gc_val;
	GC		gc;
	Display		*display;

	result = xv_create(NULL, SERVER_IMAGE,
			      XV_WIDTH, 16,
			      XV_HEIGHT, 16,
			      SERVER_IMAGE_DEPTH, window_depth,
			   NULL);
	display = (Display *) xv_get(librarian_base_frame->base_frame, XV_DISPLAY);
	temp = XCreatePixmap(display, xv_get(librarian_base_frame->base_frame, XV_XID), 16, 16, window_depth);
	gc_val.foreground = BlackPixel(display, DefaultScreen(display));
	gc_val.background = WhitePixel(display, DefaultScreen(display));
	gc = XCreateGC(display, temp, GCForeground | GCBackground, &gc_val);
	XCopyPlane(display, pixmap, temp, gc, 0, 0, 16, 16, 0, 0, 1);
	xv_set(result, SERVER_IMAGE_PIXMAP, temp, NULL);
	XFreeGC(display, gc);
	return(result);

The resulting Server_image has depth 0, obviously wrong.  If I do the same
operation, but just create and use a 1-bit deep server image, it works fine.
What am I doing wrong?  Is there a bug creating deep server images this way?
