Inaccurate rendering with shuffleListeners query parameter

[veillette]

While working on #129, I noticed that having the queryParameter ShuffleListeners , lead to inaccurate rendering with the curveType button. The image position and scale as well as the rays position do not update correctly, when toggling between convex and concave optic.

It would not be tragic if this sim did not support ?shuffleListeners. So I'm going to unassign this for now, and we can decide whether we want to spend time on it when we get closer to public deployment.

This has sorted itself out after all the changes and refactoring. I can no longer reproduce by switching between concave and convex lens types. Closing.
