Check for invalid texture in draw call

This is for Issue 5578.

laser-controls don't have utility here and are designed for laser pointer kind of interactions. If you want to support controllers other than quest you can just add other headset specific controllers to the entity. What's your case?

For the texture issue I recommend opening a separate PR. Thanks
