//--------------------------------------------------------------------------
// ParticleEmitter data:
//  A note about the phiReferenceVel, it will only be useful in cases in
//   which the axis of the emitter is not changed over the life of the emission
//   i.e., a linear projectile say, or an explosion that sits in one place.  A
//   grenade, for instance, wouldn't necessarily give the desired result (though
//   it might in certain cases).
//  One more note: overrideAdvances should probably only be turned on for emitters
//   that are attached to explosions.  It prevents the emitter from advancing a particle
//   to the boundary of the update it was created in.  Its useful for explosion emitters,
//   which fake a 1000 ms update, and never update again, since we sometimes want those
//   particles to pop up with exactly the same position.  On a projectile, it's likely
//   to cause non-random looking particle "clumps" if there's a low frame rate condition
//   on the client.
