Protect against non-finite inputs on Node and OrbitViewController

🦟 Bug fix

Summary

While debugging gazebosim/gz-sim#1499 (review), I noticed that GUI and Sim are often providing non-finite values to Rendering, which often results in crashes. This PR adds some guards for situations that I ran into.

I'm going to keep investigating why downstream libraries are setting NaNs, but having the guards in place helps in any case.
