Sets the camera position, so that the particles know how far they are from the camera and can be properly sorted.
NOTE: 3D Billboard Sprite particles always face the camera, so this only needs to be Set (updated) every frame if you plan on sorting these particles relative to one another by their distance from the camera, in order to give proper depth perception of the particles (i.e. by adding the Particle EveryTimeEvent UpdateParticleDistanceFromCameraSquared and the Particle System EveryTimeEvent UpdateParticleSystemToSortParticlesByDistanceFromCamera).
