Last merge has overwritten refactored "PostvisualizationRenderer.java" and broke functionality to visualize "Agent.getGroupMembership()"

One of your last merges into master has overwritten changes of commit 9e0da1c9.

Please, restore "PostvisualizationRenderer.java". It was refactored intentionally to keep the code readable and easy to extend. Then, include your changes cleanly so that existing functionality is not broken - thanks.
