/**
 * Since subprocesses are autolayouted independently (see {@link #handleSubProcess(FlowElement)}), the elements have x and y coordinates relative to the bounds of the subprocess (thinking the
 * subprocess is on (0,0). This however, does not work for nested subprocesses, as they need to take in account the x and y coordinates for each of the parent subproceses.
 * 
 * This method is to be called after fully layouting one process, since ALL elements need to have x and y.
