Bug 282875 [UI] Allow parts of models to be rendered
We need to change the rendering protocol to allow a 'createGui' to specify the container it should be created under (in SWT-land this would be a Composite). This is necessary to facilitate unit tests and to allow the ad-hoc rendering of chunks of a model within an arbitrary container (i.e. a Dialog or Wizard). In order to do this we'll have to make an API change to the PartFactory's 'createWidget' so that it will get the parent container as a parameter. In order to 'upgrade' an existing PartFactory you would simply replace the code you're currently using to find the correct container with the new parameter's value.

					if (logger != null)
						logger.error(e);
				}
			}
		} else {
			newWidget = null;
		}
		return newWidget;
	}
	@Override
	public void hookControllerLogic(MPart<?> me) {
		super.hookControllerLogic(me);
		Widget widget = (Widget) me.getWidget();
		if (widget instanceof Shell && me instanceof MWindow) {
			final Shell shell = (Shell) widget;
			final MWindow w = (MWindow) me;
			shell.addControlListener(new ControlListener() {
				public void controlResized(ControlEvent e) {
					w.setWidth(shell.getSize().x);
					w.setHeight(shell.getSize().y);
				}
				public void controlMoved(ControlEvent e) {
					w.setX(shell.getLocation().x);
					w.setY(shell.getLocation().y);
				}
			});
