	It includes all the features of ParticleSystem.

	Special features and Limitations:	
	- Particle size can be any float number.
	- The system can be scaled
	- The particles can be rotated
	- On 1st and 2nd gen iPhones: It is only a bit slower that CCPointParticleSystem
	- On 3rd gen iPhone and iPads: It is MUCH faster than CCPointParticleSystem
	- It consumes more RAM and more GPU memory than CCPointParticleSystem
	- It supports subrects
	@since v0.8
