      • translateNestedSubprocesses

        protected void translateNestedSubprocesses​(org.activiti.bpmn.model.Process process)
        Since subprocesses are autolayouted independently (see 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.
