/** @class ParticleSystemQuad
 * @brief ParticleSystemQuad is a subclass of ParticleSystem.

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.
