    xlogo = XtCreateManagedWidget("xlogo", labelWidgetClass, toplevel, NULL,0);
    XtSetArg(args[0], XtNbitmap, XCreateBitmapFromData (XtDisplay(xlogo), 
	XtWindow(xlogo), xlogo16_bits, xlogo16_width, xlogo16_height)); 

The problem is that XtWindow(xlogo) returns 0, not a valid window id.
X widget doesn't get a window until it's realized.  The simplest thing
is to instead use the root window of the screen.
