This is just the custom-node example plugin that comes with the plugin API. It draw a single (deforming) square.
I assumed that the Drawable's computeBound() method, which returns a BoundingBox, was used for collision detection. The overridden computeBound() method in the example plugin appears to be returning reasonable values, and it does get called by winviz. If not for collision detection, what is this method for?
