/** @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
- It supports subrects
- It supports batched rendering since 1.1
@since v0.8
