- The emission rate of ParticleEmitters can be set as particles per second (instead of particles per frame).

- Particles that are outside the sub aren't visible inside hulls even if they overlap with the sub.
- ParticleManager takes the movement of the particles into account when determining which particles to cull. For example, a particle that will move upwards can be emitted even if it's below the camera view.
