/** @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
