/** @brief CCParticleSystemQuad is a subclass of CCParticleSystem

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 CCParticleSystemPoint
- On 3rd gen iPhone and iPads: It is MUCH faster than CCParticleSystemPoint
- It consumes more RAM and more GPU memory than CCParticleSystemPoint
- It supports subrects
@since v0.8
