[Performance]Time taken Camera.Render.Culling.ParticleSystem.Prewarm increases to relation to the PaticleSystem was outside view
Culling.ParticleSystem.Prewarm takes longer to start the longer the Particle System was culled.
To Reproduce:
1. Open the scene in the attached project & Play.
2. Press space bar to move the particle system off-screen.
3. Press space bar to move the particle system back.
4. Observe in the profiler that, ParticleSystem.Prewarm is called.
5. The longer you have waited between 3 & 4 the more time is taken byParticleSystem.Prewarm.
This is more noticeable on a device, for example on iPhone 5 after waiting 10-15 secs the it takes about ~ 0.8ms, but ~4ms if the particle system moved back after ~ 5 minutes.
